When you run PowerPC apps on an Intel Mac, a translator called Rosetta is used by the system. This will use more RAM and those apps will not run as fast as their equivalent Universal apps. However, unless your G5 was a Power Mac dual or quad core, an Intel iMac running a PowerPC app (using Rosetta) may be as fast or faster than the G5 running the same app natively.
Will my PowerPC Apps work in the Intel system?
So the answer is YES, most (but not all) PowerPC apps will run on Intel Macs using Rosetta. Increasing your iMac's RAM will improve performance (but that's always true).
Would they harm the system?
NO. Rosetta is a built-in part of the system. Sort of like Classic, but better integrated and more seamless.
Adobe was late in making their apps Universal, but I believe they have completed the transition. The upgrades are not free, unfortunately. If your current versions run fast enough on your Intel iMac, you should keep using them.
Thanks for the great response!
I had heard about Rosetta before but I thought the system would inform whenever an App was running under Rosetta, as we were able to see with Classic...
That explains the 1GB ram being all used, as Photoshop and Flash are two professional Apps... I'll run some tests working on heavy files at the same time before deciding if I buy another 1GB or 2GB ram.
If you don't mind, I'd like to copy your response and paste it at the G5 forum, where I also posted the same question... as I believe many Mac users may own both systems.
Of course I'll give you the credit for the information.
