I did a clean install of Mountain Lion last month. I reinstalled all my apps from freshly downloaded installers, rather than copy anything to my pristine system folder. I copied my music, photos, and other documents from my Time Machine drive. Now, I have constant permission problems on all these folders. I don't have permission to do anything to any of these folders or subfolders. I can't rip a CD to iTunes, I can't sync my iPhone. I can't download anything. I can change the permission on each folder individually, but there must be thousands of them. There must be an easier way. Changing permissions for a parent folder doesn't change the subfolders. Disk Utility reports no problems when I repair disk permissions. Thanks in advance for any help.
Also, the iPhoto app disappeared after the clean install. I don't know how to re-install it. Do I have to wipe my drive clean again and install Leopard from my original DVD that came with my iMac? That would be a huge job to get back to Mountain Lion. I'll post this question in another thread and link it here.
