The release notes accompanying the OS X 10.9 Mavericks Developer Preview indicate that the new OS is compatible with all Macs able to run the current OS X version, OS X 10.8 Mountain Lion.
When Apple announced OS X 10.9 at Monday’s WWDC keynote, the company failed to get into the specifics of the software, such as which Macs would be able to run the next-generation OS. If the Developer Preview is any indication, most Mac owners able to install Mountain Lion will also have machines capable of running Mavericks.
Those familiar with the Mavericks Developer Preview tell AppleInsider that the OS supports the following Macs:
The system requirements call for a 64-bit Intel-based Mac running Mac OS X 10.6.7 Snow Leopard or higher with 8GB of disk space free.
Of course, since Mavericks is currently in beta, there’s no guarantee that the final version will carry the same system requirements as the Developer Preview.
