gameagent.com has posted a Mac Match service to instantly determine if a particular game will run on your Mac. Or you can just check out the Mavericks system requirements instead.
Operating System: OS X v10.6.8 or later
Processor: Intel Core 2 Duo
Numbers of cores: 2
Processor Speed: 1.86 GHz
Turn Mac Match On
Memory: 2 GB
Hard Disk Space: 8 GB
Video Card: NVIDIA GeForce 7800, ATI Radeon X1600, Intel HD Graphics 3000, or better with 256 MB of Video Memory
Also note that Mavericks will require Macs with a 64-bit architecture, meaning that if youre still using a Mac from as far back as 2006 with a 32-bit architecture, you’re out of luck even if Mac Match says you meet all the other requirements.
