NEW! SnowChecker

The SnowChecker application scans your hard drive for applications and allows you to only display relevant compatibility data. Other features include sorting and search. Click here to download.


Below is a list of applications and their compatibility status with Mac OS X 10.6 Snow Leopard, the most recent operating system from Apple. Please collaborate by sharing your experiences using each application and by adding applications not already listed. Note: due to abuses, registration is now required to edit the list. Thanks for your cooperation.

Snow Leopard is now available!
Order Snow Leopard from Amazon for only $25!

Update: There are now four categories: UNKNOWN UNKNOWN.png is for apps that are untested, OK OK.png for apps that work fine, NO NO.png for apps that do not work, and WARNING WARNING.png for those with some problems.

NEW! Please visit the Discussion Forum to share compatibility information and Snow Leopard tips and tricks.

Please do NOT force removal of a lock whilst someone else is editing. It's EXTREMELY RUDE and INCONSIDERATE!

Please note: This is a text based editing system. To add information, be prepared ahead of time by having your data ready to paste in (open TextEdit, copy everything from the first || , to the last || , then replace the placeholders with the information needed.), using the following format :

|| Application Name || Version || Website URL || [[image {OK/NO/UNKNOWN/WARNING}.png]] || Notes (Comments) ||

When you have replaced the placeholders with your info, and choose OK, NO, UNKNOWN, or WARNING to set the correct graphic icon. Paste the edited text into its corresponding alphabetical place in the text list. Do not add it into the code above, it doesn't work that way : )

Please also note that editing anything besides application compatibility data (i.e. ads) will get you banned. Thanks. -admin

For information about potential printing issues on Snow Leopard, see printing-issues

Java Note: After Snow Leopard installation, only Java SE 6 remains and is used for all Java applications and applets; previous Java versions (which were present in Leopard and Tiger) are gone. This may cause issues with Java apps/applets that don't work correctly with Java SE 6: these will need to be updated to work with Snow Leopard.

Quicksilver b56a7 OK.png b56a7 reported to work perfectly, though the "Services Menu Module" Plugin causes Quicksilver to crash on launch. You can delete/move "Services Menu Module.qsplugin" from "~/Library/Application Support/Quicksilver/PlugIns" to temporarily fix the issue. Other plugins may cause a similar crash, including the "Airport Module" plug-in. If you use Spaces and "Show Icon in Dock" is unchecked in preferences, when you invoke Quicksilver, it will only open in the Space that it was started in. Workaround is to have "Show Icon in Dock" checked, which is a bit annoying either way. Airport module crashes/doesn't work.
