Which versions of Photoshop, all of them? I have CS6 and am not satisfied with it because it's bloated. I want to go back to CS3 or at least CS5.
Look at the specs for Photoshop CS6!
Multicore Intel processor with 64-bit support
Mac OS X v10.6.8 or v10.7. Adobe Creative Suite 3, 4, 5, CS5.5, and CS6 applications support Mac OS X Mountain Lion (v10.8) when installed on Intel-based systems.**
1 GB of RAM
2 GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
1024 x 768 display (1280 x 800 recommended) with 16-bit color and 512 MB (1 GB recommended) of VRAM
What did they do, hire some sloppy hackers to code it? This is disgusting. CS3 ran on freaking iMac G4s.
PowerPC G4 or G5 or multicore Intel processor
Mac OS X v10.4.8-10.5 (Leopard)
512 MB of RAM
64 MB of video RAM
2 GB of available hard-disk space (additional free space required during installation)
CS3 would see my machine and feel humble to operate on such a beast.
Believe it or not, a lot of the software today (CS6) is actually written to take advantage of the current hardware and would have compatibility issues with older hardware.
Have fun editing 12Kb flip phone photos! Some of us actually use the acceleration features that take advantage our latest hardware or OS we're running.
