Hey y'all, I'd really appreciate some help here because I'm almost at breaking point :/ Okay so, I installed the Leopard beta. Stupid and possibly illegal/unethical, I know, but hey, I couldn't help myself. After realising that it was a real pain to use, I wanted to revert back to Tiger. Whaddya know, it won't let me! Once you upgrade your system, you can't downgrade, apparently. So I figured I'd SuperDuper! my hard drive to my external one, erase and install Tiger, then restore it back to how it was using Disk Utility. It restored okay, but then it wouldn't boot! The little pinwheel (not beachball) sat under the Apple startup logo, spinning and spinning for hours.. I'm guessing this is because I'm trying to boot a Leopard hard drive under Tiger..? So now I'm at the point where I erased and reinstalled Tiger again, and I'm simply trying to drag-and-drop my Users, Applications, and Library folder from my external hard drive to Macintosh HD, but even THIS doesn't work, as it says "This operation could not be completed because you do not have sufficient privileges for some of the items". Please, please, please.. I am so desperate and so confused. I know what I did was stupid and it'll certainly teach me a lesson or two, but for now, please help me :(
