are the cs3 products power pc programs? i ran the cs3 master collection on my 32-bit intel-based 2008 macbook pro without problems. but when i upgraded to a 2011 64-bit macbook pro, the same cs3 software, as well as all of my 2010 autodesk software, seems to lag the machine down like crazy.
after three new logic boards and the same problems continuing, i finally had a manager at applecare tell me that it was not the computer that was the problem, but that it was because of cs3 and autodesk, that both of those older programs are 32-bit ppc programs that were revving rosetta up like crazy and causing all of my graphics problems.
at first, i accepted his answer, but have since grown suspicious. i work with 20 other people in the same department that all run various versions, some of them older than mine, and many of them on new apple products, without issues.
for examples of my graphics issues, see below:
CS3 was PPC and Intel. Get Info on the application to switch between the binaries.
Yes, running in Rosetta is slow, and crash prone.
