Hi guys I need your advise on an iMac 17" Core 2 duo. I got this mac since 2007 and it became super slow since 2008 .....i wanna fix it i don't know how. Bootup time is at least 6 mins, Everything takes at least 3-4 mins to load, recently things ain't really loading at all. I've had reformatted it because I thought that would fix the problem; it didn't work. So I suspect it is a hard drive problem and I am considering buying a hard drive to end the misery. The problem is that I am not sure if it is really a hard drive problem. Are there any other ways that would make a mac slower? Thanks for your advise.
