first off i am going to give the specs of my mac so that you all can have a better idea of what I am working with. Imac intel, 3.06 ghz, 4gig mem 500gig hd, Mac OS X Server 10.6.8 (10K549) I purchased this mac about 6 months ago for a home studio for music production and have been generally happy with its performance. There are however some pretty big problems that I believe are OS and Hard Drive related. The Mac refuses to shut down or restart on its own it will idle with the white screen with the apple in the center for days on end if left unattended. attempts to run disk utility turn the computer into a mess and also i cannot perform permission repairs or wipe the OS because it needs a copy of server and I do not have access to the original disks. Since I am doing music I have no need for all of the needless script and background operations that server continuously run's. I believe that is part of why my mac is running so slow. Also file transfers are nightmarishly slow and the mac refuses to free up memory on its own and will automatically cache 2 gigs on start up that I can never seem to free up even when next to nothing is running. I have a brand new copy of snow leopard that I would like to be able to do a clean install with. I think this would fix a lot of the issues I am having but you are talking to a busy Marine who has a very limited number of hour's to deal with these kind of tech problem's. Any feedback or advice would be much appreciated. Thank You!
