I’ve been bad about upgrading the OS of my MacBook, and now it’s hopelessly out of date. A lot of software no longer runs on Leopard, including Chrome autoupdate, TextMate, and GIMP. Lack of Chrome autoupdate means no updated Flash, which means no YouTube. Time for an upgrade.
Unfortunately, you cannot upgrade to Mountain Lion without going through Snow Leopard first, and Snow Leopard is no longer sold in stores or on the apple.com site. After calling a local Apple store, I found out that the only way to get the upgrade is to call 1-800-MY-APPLE and ask for an upgrade. They’ll ask you for the serial number of your Mac in order to ensure compatibility, your email address, and standard billing information. The cost of the upgrade disk, without expedited shipping, came out to about $26 in my case.
Hope this helps those of you who procrastinated like me and are searching for information about where to get the Snow Leopard upgrade.
