Hello, For some reason or another, I right clicked on my Macintosh HD icon, chose get info, then changed permission to read & write, and applied it to all enclosed items. Then I restarted my MacBook and it wouldn't boot. It would just hang on the Apple logo boot screen with the spinning thing. So I did some research online and saw that I would have to wipe my whole hard drive and start over since I applied read & write to all enclosed items. I put the OSX disk in, and booted to it. Before I went to install a fresh copy of OSX, I tried to repair disk permissions instead. To my delight, it worked. I was able to boot like normal. But now I am having some strange problems. -When I load Firefox, the bouncing icon will be all jumpy. -When I log into Skype, the log in sound will only play halfway. -The most weird and major problem is the no setting will save at all. If I add a new bookmark in either Safari or Firefox, then quit and reopen the program, it will not be there. If I change my home page, the setting won't save after I quit out. If I remove something from my OSX dock, then log out then log back in, it will be back. Any ideas on what I need to do?
