Basiswissen

Photoshop CS5 is the first 64-Bit capable version of Photoshop for OS-X. At the same time it's Intel only - dropping all support for the old Power PC platform. All of our plug-ins can still be used with this new Photoshop version on the Mac. They might not work directly after installing CS5 however because Photoshop's default configuration is set to running in 64-Bit mode. To use the plug-ins with Photoshop CS5 you have to configure Photoshop to run in 32-Bit mode as all previous versions of Photoshop have. First locate the Photoshop CS5 executable using the Finder. It should be in the Applications/Photoshop CS5 folder on you HD unless you installed it elsewhere. Select the executable and right click to bring up the info dialogue. Alternatively press cmd+i after selecting the file. On the info panel check the option that tells OS-X to run Photoshop CS5 in 32-Bit mode. The screenshots used here were taken on a German copy of OS-X but the locations of the respective items will be the same for other languages.

When will we support the 64-Bit Photoshop on the Mac natively?

We have just added 64-Bit support to the PC version of ColorPerfect so you might wonder if and when we will do the same for OS-X. Directly supporting the new 64-bit mode is likely going to take a while. That is so because of another major change in the software's architecture that is exclusive to the 64-Bit version. You might have read about that before. It was on the media when CS4 turned out not to be 64-Bit enabled on the Mac. The architecture used by Adobe for all 32-Bit versions of Photoshop on the Intel Mac platform is called Carbon while the one mandatory for 64-Bit software on the Mac is called Cocoa. As you know we do support all OS-X Photoshop versions back to 7.0 with three different plug-in versions developed on different systems. The 64-Bit compatible version would be the fourth. We're confident that this will happen eventually but until it does please be patient. Feedback on whether you are a registered user who is actively waiting for this version would be appreciated as knowing the actual number of users doing so might have an impact on the priority we assign to this.
