I purchased CS6 Photoshop and now I can't open it on my IMAC because it's an older processor that doesn't have the capacity to handle 64bit. The windows version has an option for 32 bit but not MAC. Seems a "bit" unfair.!

Yes, some of the older Intel iMacs were 32 bit only.

Apple is dropping 32 bit support rather quickly, and we had to do the same.

Microsoft is not dropping 32 bit support in the forseable future.

Hi Bob,

The system requirements are listed here:

There are some limitations on both on the Win and Mac side. XP for example doesn't support some GPU enabled features like 3D.

Let me know if you need assistance with a return, or suggestions for newer hardware.

Hi Jeffery, I feel like I am in a Catch 22. I decided to try to return CS6 and get an older version of CS5 with 32 bit. Now I found out that Adobe doesn't sell older versions and it is not easy to find older authorized versions at a good price. Maybe I should upgrade my processor but that is not easy or cheap to do as well. Any advice?

Ugh. Yeah. Obtaining older versions is tricky. This article covers ways to protect yourself from counterfeit versions:

That said, only current versions are supported with free support incidents.

On a mac, there isn't a way to upgrade just the processor. It may be worthwhile to upgrade the system depending on how much work you do. A 64bit Mac would allow you to use more than 4GB of RAM. Also, newer systems with SSD drives provide a pretty big performance win.

Probably not what you wanted to hear, but those are the options and some info that may help.
