I have a Macbook running OS X 10.6 that "freezes" at the login screen. The system will turn on normally, but when the login screen appears the mouse and keyboard do not allow any of the options to be clicked. I can move the mouse but can't click on anything. After forcing shutdown and restarting about 5 times it finally allowed me to log in, but it froze shortly after logging in. I noticed a few times that if I wait long enough after clicking on a user it will eventually log me in...I"m thinking it's possibly a hard drive issue? Any ideas?
Here's what I've tried so far...
-USB Mouse (same results)
-Safe Boot (same results)
-Apple diagnostics show everything is OK
Since it is 10.6 I believe I would need the disk to get into Disk Utility, but any suggestions or ideas as to what might be the problem would be great. Thanks!
