Q: Can I use a Gateway Keyboard on a mac?

Yes.

(126241)

The Windows keyboard will function with your iMac, exclusive of any special function keys that may require a driver.  On the Windows keyboard, the two keys (Windows and Alt) next to the space bar are juxtaposed, when compared to their positions on a Mac keyboard.  Just remember that the Windows logo key functions as the Apple Command key and the Alt key is the same as the Apple alt/option key.

There are two helpful articles about using a non-Apple keyboard with Apple Mac product;

one is from Microsoft support and the other is from Apple Support. (Note: Boot Camp.)

This article, which should help in a reverse logic, similar to Microsoft's w/ additional ideas:

•Boot Camp: About keyboards and key assignment for Microsoft Windows - Apple Support

•Keyboard Mappings using a PC Keyboard on a Macintosh:

Hopefully these will be of some help since most times the keyboard can be used without issue

however a few instances where an official Apple keyboard (even older white plastic) is a

better choice for a Mac with OS X, than a windows-based PC keyboard for startup shortcuts.

Good luck & happy computing!
