Sure, Macs don’t have viruses. Sure, they tend to be much more stable than their PC counterparts. Sure, the technology upon which Mac OSX is built is much more robust. But that doesn’t mean that you won’t run into an occasional problems.
So in my random ventures online, I found a great article on MacInstruct about what to do if you get in a bind on your mac. The article has some good tips, even if your Mac begins to act a little funky. Its rare, but it happens.
Take a look, both at the article and at the site itself – its got great tips for a wide range of users (not to mention amazing graphics like the one for this post!)
