I'd like to see if there's anything I can do to speed up my work Mac (other than buy hardware, as my company is waiting until a certain point to do this) . I'm running running on 10.4.11, have a 2.16Ghz Intel Core 2 Duo processor and have 1GB 667Mhz DDR2 SDRAM. The machine doesn't appear to be too cluttered and running Activity Monitor to look at processes doesn't seem to show anything that shouldn't be there (afaik). It runs perfectly fine on startup, even when using lots of programs, but as the day goes on gets slower and slower until I have to restart. I generally run Word 2004, Thunderbird, Firefox and Photoshop CS3. Ideally, I need to have these running side by side all day. Is there anything I can do?
