Dear forum, hi I'm new here and came here as last resort because I just don't know what to do anymore. I hope one of you can maybe help. Ok, the problem is that... My Macbook pro is sloooow!!! It is soooo "curse" annoying! I just don't know what is wrong with it. When I try to run programs such as FL studio 11 it is slow that it freezes a bit, like missing frames... Seconds in a timer go from 1s to 4 then 7 instead of just 1, 2, 3 and 4, etc... With Final cut Pro it's the same problem. I have filmed a Rally course in the NL at full HD with 60fps, but when I try to edit the movie parts in the program it misses frames and slows down. It is super annoying. I can't work like this... I just don't know what the problem is. -When I run the activity monitor it doesn't show any huge cpu usage (FL studio only uses 10%!! ) -I completely cleaned my mac with MacKeeper -Have no viruses or stuff like that. -I have more then 300gb free space on my HD -Temps don't really go up, around 80°c max, which is normal... -I have the latest software and Mountain lion. -2GHz interl core I7 processor. -4gb 1333 MHz DDR3 Memory. What must I do to be able to run my programs?
