So my Dad's Mac Pro has been acting up the past year. I can't tell if it just needs more RAM or if something is the matter. It's a pretty pimped out machine, but lately it's been sooooo slow. I'm having dell 1997 flash backs here. I'm talking 20-30 seconds to open a "file open" button. It's odd because I can edit huge video projects and photoshop files, but it's the LITTLE things that are hiccuping. perhaps someone can help? Here are the specs: Model Name: Mac Pro Model Identifier: MacPro2,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 3 GHz Number Of Processors: 2 Total Number Of Cores: 8 L2 Cache (per processor): 8 MB Memory: 4 GB Bus Speed: 1.33 GHz Boot ROM Version: MP21.007F.B06 SMC Version (system): 1.15f3 Serial Number (system): 1572305EUPZ Hardware UUID: 00000000-0000-1000-8000-0019E3F944E6 again, the symptoms: sometimes when trying to open a file or function the computer stops, and makes that "warming up sound" like its rebooting and REALLY takes its time to think. It seems to only be doing these symptoms on small functions and tasks.
