We've had several folks let us know about an apparent problem with the new iMacs, both in post comments and by email tips. There has been an Apple Discussions thread about the issue, which involves random freezes in the new iMac. It apparently causes the interface to completely lock up and requires the user to perform a hard restart to recover. Macworld is reporting that Apple has now admitted that there is a problem. An Apple spokesman told Macworld that they are "tracking down the root cause of this bug, and will issue a software update which corrects it as soon as we can - most likely later this month."

Want to lock up OS X? Of course you do! When friends with Windows complain that Macs don't have all the features of PC's, you can whip out this little trick to show then that, yes, OS X can lock up just as tight as Windoze. How? You'll need two Macs: one can be any kind of Mac, the other has to be a laptop (also a Mac).

First, mount a network volume onto the laptop any way you like. I have a Mac mini in the den we use as a file server (amongst other things). I mount one big honkin' USB drive on all our laptops (three iBooks, a Macbook Pro, and a Macbook) and use it as our Backup.app drive. Next, close the laptop. This puts it to sleep, and "freezes" the state of the machine. Step three involves driving/biking/running as far away from your home network as possible. For this to really work, you'll want to get near another WiFi network. Now here's the tricky part. Upon opening the laptop, quickly navigate to the Finder and open a new window. Anything to access the Finder, essentially, and prompt it to start looking for that (now missing) network volume. During this, the Mac will be scouring the airwaves for a new signal. Upon finding one, it'll ask to join. Say yes, and if you've got your Airport strength in your menu bar, you'll see the name of the network start to scroll across. For me, that's where the party ends.

I've tried this on all flavors of Tiger, on a G3, G4, and Intel-based laptop, and it all does the same thing: rainbow wheel and lock up. Once I left my G4 iBook on for 4 hours, and Finder never recovered. No key combos will return sanity, just a floating wheel, with no other response from the OS. Not even CPU gauges update! The only solution is to hold down the power key and reboot. Who says PC users get all the fun? You'd think with UNIX being built for networking...

I'd bet that many of us are familiar with the scenario that Don Foy describes at Macsimum News: You're listening to your iPod when it inexplicably freezes up. No amount of button pushing will get it to do anything. Or, you plug it into your Mac and nothing happens. It doesn't show up on the desktop and iTunes does not see it. How do you remedy the situation? As Don suggests, remember the five R's:

• Reset your iPod Find out how to reset your model here.
  
• Retry with a different port. Perhaps the iPod itself isn't to blame?
• Restart your computer
• Reinstall the iPod software and iTunes
• Restore your iPod Caution: This wipes everything!

This should have your little friend happy and healthy again in no time. Now, wasn't that easy?
