Apple OS 10.5 Leopard
Apple OS 10.5, aka Leopard, was released last Friday and is full of new features. The best review we have seen is from John Siracusa, it is very deep and covers pretty much everything there is to know. For a higher level quick and slick overview, check out Apple’s guided tour. As with any software, particularly operating systems, there are some bugs. One or two of them are significant including a Windows-esque blue screen of death in some upgrade circumstances. Unless you are in a position to do a clean erase and install, our advice is to wait until Apple has had time to offer patches or verified procedures to correct these problems. REMEMBER: When attempting any kind of upgrade or fresh installation, mirror your startup disk to an external drive before doing anything!
