Apple’s OS X Snow Leopard is now available for all Macintosh users with the Intel-based Macintosh.
Things to Do Before You Upgrade
Be sure that your data are backed up and you’ve checked the compatibility list. Many vendors are still updating their software and it may not work after the upgrade. Software that utilizes specific drivers (sound, video, etc.) may not be compatible and will either be unusable or will crash the installation. For software that you use regularly, be sure to check the vendor’s site for an update first.
My Personal Experience
I upgraded two MacBooks; one went very smoothly but the other crashed and burned due to some software incompatibility and I had to reformat the drive. Fortunately, I had a good backup; without it I would have lost everything.
What’s New?
Finder: rewritten for Snow Leopard, restore deleted items to original folders, enhanced and larger icon views, more reliable disk eject, sortable search results.
Dock: scroll through your stacks, activate Exposé from the Dock, navigate folders in stacks.
Systemwide: faster shutdown and wake-up, automatic updates for printer drivers, new Automator templates, text substitution, faster Time Machine backup, all-new thesaurus, date in the menu bar, and many other refinements.
