Yesterday, I had a folder (called "Other") with read and write access for Joseph (Me), everyone, (unknown), and Joseph (Me, again), but for some reason I couldn't write to the folder - I only had read access even though three forms of me had read and write. I tried changing the permissions of the parent folder to read and write (which they already were for everyone, but I added my account too for the hell of it) and then applying it to the enclosed items, but that just added "wheel" to the Other folder's permissions and didn't fix the problem. Repairing permissions did nothing, I ended up just setting my entire Macintosh HD to read and write for everyone and a few other people, then applying to enclosed items. That worked, but then for some reason it changed my external hard drive's permissions to "Custom" for Me, Me, unknown, and everyone. I can't access my external at all now, and nothing happens when I try to change its permissions. There was a little checkbox that said "Ignore permissions" or something, which I unchecked, but it didn't do anything and it's not there anymore. I'd just format and reinstall Leopard, but I can't access my backups, and I can't find my Leopard DVD anyway. Anybody have any idea what the hell's going on? Edit: Also, I haven't changed any permissions or installed or done anything that could've caused this. All I've done the past couple weeks is play Starcraft and use Photoshop. Also, Tiger > Leopard. Photoshop stopped working, so I tried restarting my computer. Now it just keeps restarting. It turns on, loads (grey Apple screen with the spinning gear) for about a minute and a half, then restarts again. I tried resetting the PRAM a few times but that didn't help.
