EazyOakIf this keyboard operates in the same manner as the Topre clone RC930, then it will work on a Mac with a couple caveats. If you want it to act like a "true" Mac keyboard, you'll need to use the OS X keyboard preference pane to map the Alt key to Command. Further, the board does not recognize any inputs before the operating system is loaded. So if you dual-boot Windows with Boot Camp or need to run the recovery console, you'll need to have an Apple or other fully Mac-compatible keyboard attached.
