Even if others can't, Apple (NASDAQ:AAPL) has no problem backing Windows 8.

In an update released Thursday afternoon, the company added support for running Microsoft's (NASDAQ:MSFT) latest Windows operating system in Macs running the 10.8.3, or "Mountain Lion," edition of the Macintosh OS.

Apple has long made it possible to "boot" or load Windows on a Mac via a native software program called Boot Camp. The company upgraded the app in 10.8.3. Other improvements include fixes to certain flaws found in earlier versions of the OS, plus the latest edition of the Safari browser.
