1: Previously encountered this problem in Windows, and then deleted the current user directory all about Adobe software and files, the folder is OK, in the imac may also encounter this problem.
Method:
In the imac computer, we hold down the option key, and then click the "Go" button in the Finder on the computer desktop to go to the "repository" and find Adobe files/folders to delete them.
2: After the deletion, we go to Adobe Application Manager and install the software after the system has been cleaned up.
3: Then we break the network, and then find Photoshop CS6.DMG program, you will find that the "program can not initialize" the window, haha!
4: After the installation is ready to use OH.
5: Enjoy your Mac version of PS, no need to switch back and forth between the system!
If it's still not working, we may have a problem with the imac system or the imac is not compatible with our Photoshop version, just to find a compatible imac Photoshop software installation.
