The good news is PhotoShop seems to do all that it's supposed to. The bad news is that this app ignores pretty much every Mac convention and UI standard. You might as well run the PC version in Boot Camp or a virtual machine.

-- Installation is horrible. You have to run "Setup" from a folder buried two layers deep in the DMG, and the release notes, while full of information ABOUT installation, fail to mention this rather important fact.

-- Install places a gratuitous copy of the Opera browser on your computer. Depending on your setup, you may find this browser opening web pages instead of Safari. Urgh.

-- Uninstall is worse. You have to run Setup again, which then tells you to de-authorize the product first (why can't setup do this?), which is funny since there is no de-authorize option.

-- You have two window choices: minimized in the Dock or full screen. Yep, the app takes over your whole desktop, no matter how big your screen and how small the photo you are working on. Urgh.

-- Forget Mac UI. You have non-standard menus and Adobes own half-baked GUI model. Simply browsing for a photo to edit involves one app switching out and a different app launching. A truly awful experience.

So **** for functionality, but * for creating the most awful Mac app experience I have ever seen. There are better choices.
