I have recently bought the new Mac Pro Intel and I have photoshop CS2 and Illustrator 8. I have NOT installed either as I have heard they will not perform properly on the new Mac. Can anyone tell me their experience / opinion.
Illustrator 8? I think the earliest carbonized version of illustrator is 10, although 9 may have been. 8 is definitely not carbonized. You will not be able to run that on a mac pro, the software is 9 years old and written in PPC code for classic mac OS. Photoshop CS2 will run with no issues after you upgrade to 9.0.1, a free download from adobe.
I ran Creative Suite 2 (PS, AI, DW mostly) on a 2GB Macbook (not pro) for nearly a year and it worked fine. PS is much slower to start up, but once it is running performance is ok - but some advanced operations will be slower.
