When you boot OS X 10.6 to Safe Mode by holding the Shift key after hearing the boot chimes, you will see a gray progress bar appear at the bottom of the initial gray Apple screen. While this bar is showing the system will run various maintenance tasks such as checking the filesystem and clearing some caches, after which it will load into Safe Mode. This process should only happen if you intentionally boot into Safe Mode, but there may be instances in which you see it happen at each boot, even if no keys are held during bootup.… Read more
Admit it! Sometimes you are so mad, you just want to slam something on the floor, step on it, and then kick it a few times. I know a friend who did just that with his portable drive only to later regret losing data and hurting his big toe. If only he had had the IoSafe Rugged Portable, his data would have been safe. His toe's another story, however.
First introduced at CES 2011 with a bang (quite a few bangs, actually), IoSafe's Rugged Portable is the first mobile external hard drive that can really withstand serious beatings and abuse. The drive can handle drops, water submersion, dust, chemicals, and being crushed by a vise. I have personally shot at it with a shotgun--at a demo, not out of anger--and it didn't break.
This means that if you happen to drop it in the street and the thing gets run over by IoSafe SoloPro can handle. To make up for this, the Rugged Portable is about 15 times more compact and lighter. The drive is slightly smaller than a 3.5-inch internal hard drive and weighs about 1 pound. It's designed to be carried around, while the SoloPro is meant to be used at home only. … Read more, chances are it will survive quite easily. As a matter of fact, the only situation it seems the Rugged Portable won't survive is extreme heat, which its brother the
Users may find that kernel panics can occur when running system utilities like Time Machine when other programs are installed and causing issues. The problem can be narrowed to a third-party installation by booting in Safe Mode. If Time Machine runs properly in Safe Mode, an extension or program is causing your crashes.

Often when troubleshooting systems, you might wish to boot into Safe Mode to run in a minimized boot environment to test if a third-party extension or add-on is causing problems with your machine. In addition, booting to Safe Mode also runs some cleaning and maintenance routines on your system, which can help iron out problems.
Most people know about using the keyboard to boot to Safe Mode, by pressing the Shift key down after hearing the boot chimes, and holding it until you see the grey Apple icon with the spinning indicator below it. You may also see a progress … Read more
If a group of scientists can get their project off the ground, there's a chance U.S. air travelers may one day be able to bring aboard more liquids in their carry-on luggage again.
The team, led by Oklahoma State University chemistry professor Allen Apblett, has come up with what it says is a nanomaterial that can both detect and neutralize some dangerous explosives. If deployed in a practical manner at airports in the U.S. and elsewhere around the world, it could, in theory, make it possible once again for some people to bring more liquids with them … Read more
A German advertising agency highlights an innovative idea from Mercedes-Benz in this Web video.
The Mercedes-Benz safety feature, "Pre-Safe," is a collision warning system that anticipates oncoming hazards.
In the ad "Transparent Walls," the Pre-Safe concept plays out more like an art installation piece than a safety feature demonstration. Transparent Walls shows what Pre-Safe would look like as seen through human eyes.
Live video is captured on the onside of a wall and projected around the corner onto another wall--making the wall look transparent. As drivers pass, they can literally see what is coming from behind … Read more
Many users are aware of some boot commands for Mac OS X that provide different functionality for your system. The following is a more comprehensive list of the keyboard commands you know and many you may not.
A recent tweet from @superfetz reminded me of several boot commands I've learned over the years, so I thought a more comprehensive list would be useful for MacFixIt readers.
While you cannot run any code from Terminal or otherwise to set an order of boot devices, you can easily control where your Mac boots via keyboard commands. The following key combinations can … Read more
Sometimes problems happen for what turn out to be rather bizarre reasons. Recently we were contacted by MacFixIt reader "Frank" who had a long-standing problem where his Mac Pro would not accept boot arguments such as booting to Safe Mode when holding the Shift key.
Many times when boot commands are not working people suspect either the PRAM, the SMC, or an enabled firmware password is the root of the problem; however, this is not always the case. Sometimes incompatible hardware or faults in hardware can interfere with the ability to pass boot arguments to the system, though … Read more
We're constantly installing and uninstalling the programs that we review for Download.com, and we're sure you can imagine the mess that this creates on our computer: files, icons, and menu items that are left behind, and lots and lots of registry errors. Fortunately, there's a wide variety of registry cleaners that can tidy things up for us. Argente - Registry Cleaner is one such program. We can't say that there's anything about it that really sets it apart from the crowd, but it does an adequate job as far as we can tell.

When troubleshooting various aspects of OS X and Mac hardware, one common routine is to boot into Safe Mode to automatically run some maintenance routines and prevent the system from loading inessential features. This can be done by holding the Shift Key immediately after hearing the boot chimes when starting the system up; however, sometimes this may not work.
Booting to Safe Mode requires the Mac's firmware to send the kernel some variables (boot arguments) that it interprets as a command to modify the procedures it uses to load the rest of the system. These can be set manually … Read more
