Q&A: MacFixIt Answers

MacFixIt Answers is a feature in which I answer Mac-related questions e-mailed in by our readers.

This week, readers wrote in with questions on how to read older AppleWorks documents in newer versions of OS X, how to get files to all open in a specific application, recovering a
Mac Mini's files from a system that will not boot, and whether or not cleaning utilities are useful. I welcome views from readers, so if you have any suggestions or alternative approaches to these problems, please post them in the comments!

Question: Managing old AppleWorks documents
MacFixIt reader Don asks:

I have dozens of AppleWorks Draw program documents, ".cwk". How can I convert them? I was hoping Pages would work, but apparently not.

Answer:
Unfortunately, Apple removed support for these older formats, so your best bet is to get access to an older Mac on which you can run AppleWorks (you should be able to do this in
OS X 10.6 Snow Leopard) and then use that to convert the older documents to a more universal file format that can be opened in Pages, Word, or another word processor.

If your Mac was able to run Snow Leopard at one point and you have the installation discs available, then one option is to install Snow Leopard on an external hard drive and then boot off of that to run AppleWorks and convert your documents.

Question: Setting a default application for a file type
MacFixIt reader "tytwins" asks:

I am trying to get all .jpg files to open with Photoshop by default. I go through the Get Info window to make this change, and it sticks until I shut the computer down or restart it. Short of reinstalling the OS, is there a way to fix this behavior so that it works properly?

Answer:
Try using Get Info and selecting the desired application, and then click the Change All button below the menu where you selected the application. If this does not work then it indicates a problem with the system's launch services. Try running the commands I mention in this article to clear this and rebuild it to hopefully fix the problem. Then again try clicking the Change All button to assign the file to your application of choice.

Question: Recovering a Mac Mini's files if it cannot be repaired
MacFixIt reader Burneto asks:

My Mac Mini is dead. I think it overheated. Is it worth fixing? Can I recover disk contents?

Answer:
It may be simply a matter of a dead power supply, which can be fixed easily; however, I am not certain of the costs. If it will not power up then you will need to take it in for a repair estimate, and if you find it not worth fixing after getting repair quotes, then you can still recover the disk's contents by removing it (check out the how-to guides at iFixit) and then using an external drive enclosure to attach the drive to another system, which should allow it to be read like any standard USB or FireWire drive.

Question: Whether or not cleaning utilities are useful
MacFixIt reader Michael asks:

I have been around the Apple Support Forums a long time as a user and throughout my membership, I have heard arguments for and against using cleaning utilities such as OnyX on your Mac. The claim against the utilities is that they obstruct the OS in normally taking care of old caches and hidden maintenance routines, which may lead to problems in the future. Another opposing viewpoint is that Macs simply behave differently from Windows PCs when it comes to cleaning, and ... that these cleaning utilities are more for the world of Windows than in a Mac.

As a result of this confusion, I was wondering what your take is on this topic and whether it is necessary or not to use cleaning apps such as OnyX (or even MacKeeper) on your Mac. All I can say is that I personally use OnyX for Internet cache cleaning and nothing else.

Answer:
My stance on these utilities is they should only be used when needed. Often they offer scheduling options for cleaning numerous features all at once, but if your system is running fine then there is no need to periodically run them. If you find slowdowns in the system, then some of the routines these programs have can be beneficial.

Ultimately they should only target temporary files and so should not harm anything; however, as with any program there is the chance that a bug or two could cause problems. This is why it's best to leave well enough alone. However, the clearing of caches and the running of other maintenance scripts will not hurt the system as some have claimed.

The Windows registry has been a source of problems with performance in some situations, which is why some folks have assumed these programs are necessary on that platform. However, even the "need" for these is often questionable.

I keep OnyX on my systems as well, but do not have it configured to automatically clean or run on a schedule.

Man arrested in Alaska Coast Guard base deaths

ANCHORAGE, Alaska An Alaska man was arrested Friday in last year's shooting deaths at a Coast Guard air station on Kodiak Island that left two employees dead, the U.S. attorney said.

James Michael Wells of Kodiak is accused in a federal murder complaint of killing Petty Officer 1st Class James Hopkins and retired Chief Boatswain's Mate Richard Belisle on April 12.

Another Coast Guard member found the victims shortly after the two would have arrived for work at the station, which monitors radio traffic from ships and planes and is home to cutters, helicopters and rescue swimmers that aid mariners in the Bering Sea and Pacific Ocean. Their bodies were found in the rigger building, where antennas are repaired.

FBI agents immediately flew to Kodiak Island from Anchorage, about 250 miles away, to investigate the case as a double homicide. Few details were released in the weeks after the deaths.

Wells' arrest came after "an extensive investigation" led by the FBI and the Coast Guard Investigative Service, with help from the Alaska State Troopers, U.S. Attorney Karen Loeffler said in a statement.

Wells is expected to appear in court next week in Anchorage, Loeffler said.

No one was immediately reachable by phone Friday evening at the U.S. attorney's office to provide additional details.

Hopkins, 41, was an electronics technician from Vergennes, Vt. Belisle, 51, was a former chief petty officer who continued service to the Coast Guard as a civilian employee.

Meteorite hits central Russia, more than 500 people hurt

CHELYABINSK, Russia (Reuters) - More than 500 people were injured when a meteorite shot across the sky and exploded over central Russia on Friday, sending fireballs crashing to Earth, shattering windows and damaging buildings.

People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave according to a Reuters correspondent in the industrial city 1,500 km (950 miles) east of Moscow.

A fireball blazed across the horizon, leaving a long white trail in its wake which could be seen as far as 200 km (125 miles) away in Yekaterinburg. Car alarms went off, windows shattered and mobile phone networks were interrupted.

"I was driving to work, it was quite dark, but it suddenly became as bright as if it was day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains.

"I felt like I was blinded by headlights," he said.

No fatalities were reported but President Vladimir Putin, who was due to host Finance Ministry officials from the Group of 20 nations in Moscow, and Prime Minister Dmitry Medvedev were informed.

A local ministry official said such incidents were extremely rare and Friday's events might have been linked to an asteroid the size of an Olympic swimming pool due to pass Earth at a distance of 27,520 km (17,100 miles) but this was not confirmed.

Russia's space agency Roscosmos said the meteorite was travelling at a speed of 30 km (19 miles) per second and that such events were hard to predict. The Interior Ministry said the meteorite explosion had caused a sonic boom.

Russia's Emergencies Ministry said 514 people had sought medical help, mainly for light injuries caused by flying glass, and that 112 of those were kept in hospital. Search groups were set up to look for the remains of the meteorite.

"There have never been any cases of meteorites breaking up at such a low level over Russia before," said Yuri Burenko, head of the Chelyabinsk branch of the Emergencies Ministry.

WINDOWS BREAK, FRAMES BUCKLE

Windows were shattered on Chelyabinsk's central Lenin Street and some of the frames of shop fronts buckled.

A loud noise, resembling an explosion, rang out at around 9.20 a.m. (12:20 a.m. ET). The shockwave could be felt in apartment buildings in the industrial city's center.

"I was standing at a bus stop, seeing off my girlfriend," said Andrei, a local resident who did not give his second name. "Then there was a flash and I saw a trail of smoke across the sky and felt a shockwave that smashed windows."

A wall was damaged at the Chelyabinsk Zinc Plant but a spokeswoman said there was no environmental threat.

Although such events are rare, a meteorite is thought to have devastated an area of more than 2,000 sq km (1,250 miles) in Siberia in 1908, smashing windows as far as 200 km (125 miles) from the point of impact.

The Emergencies Ministry described Friday's events as a "meteor shower in the form of fireballs" and said background radiation levels were normal. It urged residents not to panic.

Chelyabinsk city authorities urged people to stay indoors unless they needed to pick up their children from schools and kindergartens. They said what sounded like a blast had been heard at an altitude of 10,000 meters (32,800 feet).

The U.S. space agency NASA has said an asteroid known as 2012 DA14, about 46 meters in diameter, would have an encounter with Earth closer than any asteroid since scientists began routinely monitoring them about 15 years ago.

Television, weather and communications satellites fly about 500 miles higher. The moon is 14 times farther away.

Cruise passenger: People thought ship was "going to tip over"

(CBS News) Four thousand people who have been adrift at sea for four days are finally nearing shore Thursday night. This evening, the Carnival cruise ship named Triumph is being towed into Mobile Bay, Ala., and is expected to dock by midnight.

She left Galveston, Texas, a week ago, loaded with her maximum 3,143 passengers and crew of 1,100. The brochure described a four-day cruise in the Caribbean, but an engine room fire left her adrift and powerless.

All aboard have suffered in squalid conditions, stranded as Carnival slowly brought the ship in.

When CBS News flew over the Carnival Triumph, it was within sight of shore -- but still seven hours away from the dock.

Inside Carnival cruise nightmare: Passenger describes deteriorating conditions

From up there we could see people waving, some with signs that appear to be made out of bed sheets. One said "SOS" -- save our ship -- but at this point it's not the ship that needs saving, it's the passengers.

The ship has been without power since an engine room fire five days ago. CBS News reached passenger Jacob Combs on the phone.

"The really bad part is there was no running water and toilets for almost the first 30 hours," Combs said. "Once they finally did get running water, the toilets only worked in certain places. I would say it's the worst smell imaginable."

Emailed photos (above) reveal squalid conditions. Many passengers used red plastic bags as toilets. Hundreds slept in hallways or topside to escape the foul and stagnate air below deck.

Carnival CEO Jerry Cahill insists passengers were never at risk. But 22-year old Leslie Mayberry disagreed.

"It was leaning to one side it was literally like walking up hill whenever the boat was leaning," she said. "I mean it was very scary," Mayberry said. "I mean a lot of people thought it was going to tip over and sink. And then you look out on the deck and you see the ocean and there is no one, you are just by yourself and you are so alone, even though you are around 3,000 other people on this boat."

The towline pulling the 14-story tall ship snapped, delaying Thursday's operation. It was re-attached, but it will be nightfall before the ship arrives at the terminal. Nellie Betts came from Tupelo, Miss., to meet her daughter.

"There's no reason why those people should be out there as long as they have. Why? I want to understand why," she said. "What is taking them so long to get them out?"

Once the ship arrives at the terminal, Carnival plans to put most of those passengers on a two-hour bus rid to New Orleans or even to Galveston, Texas, but some already are saying, "no thanks" - they have relatives picking them up in Mobile so they can go straight home.

Nightmare Ends: Passengers Leave Disabled Ship

After five days without power in the Gulf of Mexico, the Carnival Triumph cruise ship carrying more than 4,000 people arrived in Mobile, Ala., to greet a cheering crowd of friends and family members waiting to embrace their loved ones.

Passengers began to disembark the damaged ship around 10:15 p.m. CT Thursday in Mobile, Ala. The last passenger disembarked the ship at 1 a.m. local time, according to Carnival's Twitter handle.

As the ship docked, passengers lined the decks of the ship, waving, and whistling to those on shore. "Happy V-Day" read a homemade sign made for the Valentine's Day arrival and another, more starkly: "The ship's afloat, so is the sewage."

Some still aboard chanted, "Let me off, let me off!" and "Sweet Home Alabama."

The Carnival Triumph departed Galveston, Texas, last Thursday and lost power Sunday after a fire in the engine room disabled the vessel's propulsion system and knocked out most of its power.

After power went out, passengers texted ABC News that sewage was seeping down the walls from burst plumbing pipes, carpets were wet with urine, and food was in short supply. Reports surfaced of elderly passengers running out of critical heart medicine and others on board squabbling over scarce food.

Passengers said many of the cabins became intolerable with the smell of raw sewage. They were forced to create makeshift beds out of lounge chairs on the ship's deck.

"We kind of camped out by our lifeboat. We would have nightmares about Titanic basically happening," passenger Kendall Jenkins told ABC News Radio after disembarking from the ship.

"I am just so blessed to be back home," she added.

Jenkins was one of many passengers that were photographed kissing the ground when they exited the ship.

WATCH: Carnival CEO Gerry Cahill Apologizes to Passengers

Approximately 100 buses were waiting to take passengers on the next stage of their journey. Passengers have the option to take a bus ride to New Orleans or Galveston, Texas, where the ill-fated ship's voyage began. From there, passengers will take flights home, which Carnival said they would pay for.

Inside the buses, Carnival handed out bags of food that included French fries, chicken nuggets, honey mustard barbecue sauce and apples.

Deborah Knight, 56, decided to stay in Mobile after the arduous journey was over rather than board a bus for a long ride. Her husband Seth drove in from Houston and they checked in at a downtown Mobile hotel.

"I want a hot shower and a daggum Whataburger," said Knight.

She said she was afraid to eat the food on board and had gotten sick while on the ship.

Cruise Ship Newlyweds Won't Be Spending Honeymoon on a Boat

For 24-year-old Brittany Ferguson of Texas, not knowing how long passengers had to endure their time aboard was the worst part.

"I'm feeling awesome just to see land and buildings," Ferguson said, who was in a white robe given to her aboard. "The scariest part was just not knowing when we'd get back," she told The Associated Press.

Carnival president and CEO Gerry Cahill praised the ship's crew and told reporters that he was headed on board to apologize directly to its passengers shortly before the Carnival Triumph arrived in Mobile.

"I know the conditions on board were very poor," Cahill said Thursday night. "I know it was very difficult, and I want to apologize again for subjecting our guests for that. ... Clearly, we failed in this particular case."

Luckily no one was hurt in the fire they triggered the power outage, but many passengers aboard the 900 foot colossus said they smelled smoke and were living in fear.

North Korea nuclear test prompts stern warnings from neighbors

SEOUL/TOKYO (Reuters) - South Korea sent a stern warning to North Korea on Thursday, two days after the North tested a nuclear bomb, saying it could strike the isolated state if it believed an attack was imminent as it deployed a new cruise missile to drive home its point.

North Korea conducted its third nuclear test on Tuesday, in defiance of U.N. resolutions, pushing it further along the path of developing a workable long-range nuclear missile and drawing condemnation from the United States, Japan, Europe and the North's only major ally, China.

Pyongyang said that the test was designed to bolster its defenses due to the hostility of the United States, which has led a push to impose sanctions on the country after its long-range missile launch.

North Korea on Thursday repeated its warning that any further sanctions would provoke it into taking firmer action.

Seoul warned that it would strike if attacked. South Korea has already relaxed rules allowing troops on the border to return fire directly without seeking permission from the army chiefs.

"The cruise missile being unveiled today is a precision-guided weapon that can identify and strike the window of the office of North Korea's leadership," Defence Ministry spokesman Kim Min-seok told reporters."

Japan, which has little capacity to strike at the North if threatened by an attack because of the constraints of its pacifist constitution, said it had the right to develop such capability in response to changes in the regional security situation - but had no plan to do so at present.

"When an intention to attack Japan is evident, the threat is imminent, and there are no other options, Japan is allowed under the law to carry out strikes against enemy targets," Defence Minister Itsunori Onodera told Reuters in an interview.

"Given Japan's political environment and the peace-oriented diplomacy it has observed, this is not the time to make preparations (for building such capability)," he said.

"But we need to carefully observe the changing security environment in the region."

Any sign that Japan was moving to develop such a capability would upset neighbors China and South Korea, where memories of Tokyo's past military aggression run deep and which have reacted strongly in the past to suggestions it might do so.

It is unlikely the United States, which acts as a security guarantor for both its allies, would permit any major escalation in any conflict with North Korea.

Japan and China are engaged in a bitter island dispute that has soured relations between the two and alarmed Washington while Seoul and Tokyo have also clashed verbally over a separate disputed island.

DIPLOMATIC STAKES RAISED

The United States and its allies are pushing for new sanctions at the U.N. Security Council aimed at slowing North Korea's nuclear and long-range missile development.

President Barack Obama spoke to Japanese Prime Minister Shinzo Abe on Wednesday about North Korea's nuclear test and reaffirmed U.S. commitments to Japan's security.

"They pledged to work closely together to seek significant action at the United Nations Security Council and to cooperate on measures aimed at impeding North Korea's nuclear and ballistic missile programs," the White House said in a statement after the call.

The United States and its allies are believed to be pushing to tighten the noose around North Korea's financial transactions in a bid to starve its leadership of funding.

Japan's Onodera called on the North's biggest benefactor, China, to join in strengthening the sanctions.

"I think China is the one that is most concerned about the development ... From now on, it is necessary for us, including China, to seek effective steps, effective economic measures (against North Korea)."

North Korea has repeatedly said it is planning what it terms "stronger measures" against the United States and its allies, although it hasn't specified what those could be.

It is not capable of hitting the United States, but its medium-range missiles can hit Japan and South Korea. It also has an estimated 8,000 artillery systems stationed within 100 km of the heavily militarized border between the two Koreas.

"If the U.S. and its allies challenge the DPRK (Democratic Peoples Republic of Korea) with 'strong measures', (a) 'financial freeze' and fresh pressure and 'sanctions' over its underground nuclear test, it will react to them with stronger measures for self-defence," its KCNA news agency said on Thursday.

Australia signaled its displeasure with Pyongyang by banning diplomats seeking to reopen an embassy there from visiting the country.

While it was still unclear what fissile material North Korea used in its third nuclear test - its statements appeared to indicate that it was likely plutonium as it is easier to miniaturize than uranium - it seemed that initial environmental fears about the test were not realized.

China's Environment Ministry said it had found no abnormal radiation from the test site, which is around 100 km from its border. South Korea too said it had not detected any radiation.

Cordlife Group posts S$5.6m net profit in fiscal Q2

SINGAPORE: Cord blood and tissue banking service provider Cordlife Group posted a net profit of S$5.6 million for its fiscal second quarter, boosted by a one-time disposal gain of $2.7 million.

Excluding the disposal of its 10 per cent interest in China-based stem cell company, China Stem Cells (South) Company, Cordlife's underlying net profit grew over 50 per cent to S$3 million.

Revenue for the quarter rose 24 per cent to S$8.8 million.

Cordlife attributed the higher revenue largely to successful marketing efforts to educate expectant parents on the benefits of its cord blood banking services.

Going forward, the group is optimistic that it could benefit from policies to boost fertility and birth rates in Singapore.

The firm said the extension of Child Development Accounts, as well as the higher Baby Bonus, will allow more parents to afford to store their children's cord blood stem cells as an additional medical treatment alternative.

Jeremy Yee, executive director and CEO of Cordlife Group, said: "The Population White Paper was a very interesting one.

"What we look at, at the end of the day, is the fact that the government essentially is going to spur more investment by putting in more infrastructure in place so that the population can grow.

"More incentives have been given to parents to have more children. So all these are positives."

Cordlife's shares closed on Thursday almost 5 per cent higher at 66 cents.

Researchers develop a more accurate car navigation system

Researchers say new navigation system can be installed on any vehicle, including a Volkswagen Touareg.

(Credit:
Josh Miller/CNET)

Driverless cars could get a big boost from a new system that researchers say will increase the accuracy of in-car satellite navigation systems by 90 percent.

Researchers say the system combines conventional GPS signals with data from sensors such as accelerometers and gyroscopes to determine a vehicle's position within six feet of its location, a dramatic reduction from the current margin of error of 50 feet. The system can be installed inexpensively in any vehicle, say researchers at Spain's Universidad Carlos III de Madrid, where the system was developed.

"We have managed to improve the determination of a vehicle's position in critical cases by between 50 and 90 percent, depending on the degree of the signals' degradation and the time that is affecting the degradation on the GPS receiver," David Martín, a researcher at the Systems Intelligence Laboratory, said in a statement describing the project.

The system aims to tackle the greatest challenge faced by conventional GPS systems in urban settings: loss or disruption of satellite signal due to interference created by buildings, trees, and tunnels. The new system uses contextual information and an algorithm that eliminates deviations caused by degradation or loss of signal from satellites.

The researchers have installed a prototype system on an "intelligent
car" with the goal of capturing and interpreting all the information available while driving a car. The team sees applications of the system in driverless car systems currently under development by Google and a handful of automakers.

"Future applications that will benefit from the technology that we are currently working on will include cooperative driving, automatic maneuvers for the safety of pedestrians, autonomous vehicles or cooperative collision warning systems," the team said.

Ultimately, the team hopes to develop a system that harnesses the sensors built in to smartphones, such an accelerometer, a gyroscope, a magnetometer, and GPS, as well as taking advantage of communications tools such as Wi-Fi, Bluetooth, and GSM.
