Apple Insider reports that Apple has activated the new Find My Mac tool for developers with early access to Apple's iCloud service, allowing users to locate, lock and even wipe a lost Mac computer.

Find My Mac first appeared in developer previews of Mac OS X Lion. In May, it was discovered that the feature contained evidence that Apple was planning to migrate MobileMe accounts over to the new iCloud service, codenamed "Castle."

Upon locating a Mac, users can use the tool to play a sound, send a message, lock the screen and erase the hard drive. The service is expected to release to the public this fall along with iCloud.
