I installed Mountain Lion two days ago with no problems except that my 2011 13" MacBook Pro was a bit slower. Yesterday night there was a little shock on the keyboard at which point the system froze. A forced restart was initiated. The system became stuck on the Apple logo screen with the progress indicator animating. I reset the NVRAM. Safe mode was causing system to freeze as well. I repaired the disk permissions and did not see any problems except an issue with java. Today I reinstalled Moutain Lion and the issues still persist:
- It takes a lot of time to boot
- Logging into the desktop is really slow
- Launching Finder freezes the system, or Finder crashes outright
- The menu bar with the clock Apple and etc disappears
- Spotlight indexing is endless
I physically opened the laptop today (believing I had nothing to lose), removed the RAM and reinstalled it with no resolution to my issues. I would like to like to know if the Toshiba 500 Gigabyte hard drive is damaged and whether or not I need to replace it. I also have important files that I want to save but the laptop is too slow which prevents me from doing so.
