I upgraded to Mountain Lion and now I can't use any of my software!
What a disaster and huge mistake. Upgraded to Mountain Lion and now I can't run Autocad 2012 for Mac, any of my Adobe Creative suites software such as Photoshop, Illustrator.. and now I can't even do upgrades because Mountain Lion doesn't allow me to launch DMGs. I've lost thousands of $'s in software, not to mention time, but most importantly now I can't even work! I just tried to revert back to Snow Leopard by intalling it back in my hard drive and it won't let me. I never used Time Machine. Is there any way on earth I can revert back to my old operating software??? Please help. And if you haven't upgraded yet and are thinking about it. BEWARE - and don't do it. I've been reading that Mountain Lion isn't working with Microsoft applications either. Omy...I haven't even checked that. 😟
and of course no one at Apple support can or will help me
iMac, OS X Mountain Lion (10.8)
