Over the last three months, the OSX side of my Mac Pro has been a pain to use. I say OSX side because my Bootcamp partition which is running Windows 7 on a dedicated Intel X-25M is running very smooth and is a pleasure to use. However, on the Mac side, the system is simply unusable. I have been getting endless beachballs and constant freezes when launching Safari, iPhoto and iMovie 09 (the latter is the worst). Ive tried resetting my PRAM, resetting the video management controller and doing an archive install of Snow Leopard and nothing has helped. Ive followed previous advice and tried cloning my SSD Boot Drive onto another HDD which was completely free in my system. Booting from the cloned HDD showed better performance i.e. no beachballs. However with time, the issue has started again. So it seems it is not related to the SSD but rather to the OS which makes me think that I will have to do a clean install of Snow Leopard. Now, my Mac HDDs are set up as follows: 1: Intel X-25M 80GB G2 SSD Boot Drive 2: Hitachi 640GB Apple Stock HDD (clone of SSD Boot Drive) 3: Western Digital 1.5TB (Home folder located on this disk) *Note: Ive also tried creating other user accounts but it seems the problem persists on all user accounts. The problem is I will be starting a very important project with Photoshop next month and I want this problem to be solved. So Im thinking this is my best option: Secure erase my SSD with instructions from Macforums Reinstall Snow Leopard onto this drive Clone the Hitachi Drive onto the SSD Should this work? Any ideas or thoughts are welcome.
