I can't use Adobe Flash (vers. 8) anymore because it's a PowerPC applicaiton, and I can't log onto the World Community Grid anymore and, when I tried to reinstall the software, I was told that it "can't be opened because it is from an unidentified developer" and that I need to alter my security preferences. I wasn't able to find anything in System Preferences that could help me. Also Spaces has disappeared, and that was an incredibly useful tool for me. Anybody know what I can do? Should I just uninstall Mountian Lion?

MacBook Pro, OS X Mountain Lion
