I'm having some problems with my 2009 macbook pro, it's a 17" 2.8 GHz Intel Core 2 Duo with 4GB RAM. When it first starts, it is very slow and takes a while for the first program to open. I use google chrome and this is also very slow when first opened (about 30seconds for the first page to load), after the first page has loaded it is fine. The other problem was Photoshop CS5 and Bridge CS5 which were both running extremely slow which made them unusable and I went back to CS4. My hard drive has 79gb free and I have used OnyX to 'clean' everything up but it hasn't really made any difference. If anyone has any suggestions to get this fixed that would be great, cheers!
