My Macbook has been much slower than usual lately, and today it just stopped creating files. When I try and open Skype, it tells me it cannot create the users file, when i try to open itunes, it tells me it cannot create the itunes folder. I have repaired the disk permissions and verified the disk. Verification came back okay. I'm now at a loss as for what to do. I can't download any new files (it tells me that I'm out of disk space, while I have 50 gb's free), so downloading anything to fix the problem won't work. Thanks in advance guys..
