Recently I installed PS CS5.1, upgrading from CS4.
I thought CS5 automatically started in 64 bit mode. The problem is that it will not recognise more than 4.0 Gb Ram. I have 24 Gh installed which is recognise by the computer. Cannot find as how to check that it is in 32 or 64 bit modes.
System - MacPro 4,1. 2.66 Gh quad core intel processor.
1: How do I find which bit mode it is in?
2: If it is in 32 bit mode, how does one change it to 64 bit?
3: If it is in 64 bit mode, why doesn't it recognise the 24 GB Ram &what solutions are available?
Thanks for your help,
Did you see it install the 64 bit program? The current CS6 only comes in 64 bit flavor for a Mac not sure of the older CS5.
In the Finder, first close Photoshop, then click on the Photoshop icon (the application itself not the folder) and use Command I (Get Info)
In the info window there is a check box for "Open in 32-bit mode"
If it is selected, you are in 32- bit.
You should make sure this is Unselected to be able to run in 64-bit mode.
