This is a quick extra to share a bit of important news.
Well, we spoke a little too quickly: in our last IvanExpert News, we advised that it was safe to go ahead and install Snow Leopard (Mac OS X 10.6). We stand by that comment for general use. However, we wish to caution that there is a bug in Snow Leopard which has caused major data loss for a few people who use one of the lesser-known features of Mac OS X, called Guest Account.
Fortunately, the issue is easy to avoid, and we'll explain how right here. But you're at all nervous about it, you can also hold off on upgrading until Apple fixes the bug. When they do, we'll sound the all clear. You can also contact us and we'll be glad to answer any questions.
Here's how to safely install Snow Leopard (or make it safe if you've done so already):
- First of all, perform a backup before you upgrade. If you use Time Machine, you should already be cool. If not, we can recommend Carbon Copy Cloner or SuperDuper to help you with this task.
- If you haven't installed Snow Leopard yet, and you're not sure which version of Mac OS X you're currently running, go to the Apple Menu and choose the first item, About This Mac. 10.6 = Snow Leopard, 10.5 = Leopard, 10.4 = Tiger, 10.3 or below = it's about time!
- If you are upgrading from Tiger (Mac OS X 10.4) or an earlier version of Mac OS X, go ahead and install Snow Leopard. When you're done, do not log in as a Guest if that option is available to you.
- If you are running Leopard (if you haven't upgraded yet), or Snow Leopard (if you have), go to System Preferences, Accounts, authenticate by clicking the padlock, and click on Guest Account in the list of users. Make sure "Allow guests to log into this computer" is unchecked. Close the window. If you're on Leopard, you can now go ahead and install Snow Leopard.
This should prevent you from getting hit by the bug, and otherwise allow you to enjoy Snow Leopard's speed and stability improvements.
Snow Leopard and Printing
On a side note, the #1 problem people are having after upgrading from Leopard to Snow Leopard is printing: Their current printer drivers don't work anymore, so they need to install new drivers. If you have upgraded and are having a printing problem, here are some resources:
- This Apple support page has a chart of Snow Leopard compatibilities with numerous printer models, and links to drivers.
- This Apple support page has instructions on how to add a printer in Snow Leopard.
