A side effect of Downloads' demise will make it more difficult for users of older versions of Mac OS X to find software to download. "Apps that do not run on the currently shipping OS will be rejected," Apple's guidelines state.
When the Mac App Store launches next month, it will support only Snow Leopard, or Mac OS X 10.6, not the older Leopard (10.5) or Tiger (10.4). Several programs that appeared Monday in the top 10 on Downloads run on Tiger and/or Leopard as well as Snow Leopard.
Developers who want their software in the Mac App Store when it opens have until 5 p.m. Pacific time on Dec. 31 to submit their programs to Apple.
