I was running AE Version 6.0 in OS 10.6.8 on an iMac 2.5 GHz Intel Core i5, 16 G of ram. I installed Adobe Application Manager, that said I was 'up to date'. There were more choices to download. I thought I would be ok to upgrade the OS.
I upgraded to 10.8.5. That killed my After Effects. Before re-formatting and rebuilding in 10.6.5, is there an update I can run? Is there an older version of AE that will run in OS 10.8?
My Photoshop CS died too. I have searched to find system requirements for older versions and I can't find them.
Thanks for helping.
if you are talking cs6, I can still run cs4 on yosemite. i was able to run it on mavericks too. i still occasionally have to open some older projects in cs4 due to a few things that don't render the same in cc and a couple third party effects that they need.
i will say that when i upgrade the os, i partition the main drive, and duplicate the current boot drive (and all the apps) to the new partition. boot to that partition and make sure everything is working fine (maybe run things form that partition for a few days), then upgrade the os on the original partition and see how things go.
that way if there are issues i can always quickly reboot to the other os where everything works as before.
you don't necessarily need to partition the drive, you could use a second bootable drive, but partitioning OS X is pretty simple and free. if you search for things like 'OS X partition boot drive upgrade' you should find all the steps necessary. i used superduper to do the duplicating.
it obviously won't help you at this point, but if you try to upgrade again, i'd try this method.
