AIM for Mac 1.5 (beta 1) is now enforcing the minimum Mac OS X system requirement of 10.5.3 or higher due to the following basic reasons: OS and Application stability and faster release schedule. When we encounter an issue with a 10.5.0 or 10.5.1 update, we can either try to fix the bug with a workaround or test it the fix on a future release of Mac OS X. Our goal is to produce the best quality software in the most optimum release timeline.
So, if you're running Mac OS X 10.5, 10.5.1 or 10.5.2, please use the Mac OS X System Update or go to Apple's Mac OS X download site for the most current update. For all future releases of AOL Mac software, we'll be supporting Mac OS X 10.5.3 or higher.
For those AOL users who haven't upgraded their Leopard system to 10.5.4 or higher, could you please drop me a comment below? Is it the size of the download? You like to wait for other to test updates prior to installing?
thanks!
