    That machine is stuck at OS X 10.6.8 Snow Leopard. The most practical things you can do to boost performance are to add more memory (to the maximum of 2GB) and install an SSD. But really, it's time for a new Mac.

  • Your MacMini probably is ID Macmini1,1 (go to Apple Menu --> About This Mac --> More Info --> System Report --> Hardware Overview --> Model Identifier).

    If Macmini1,1 (2006): Snow Leopard is the highest OS supported. Memory can be increased to 2GB. The hard drive can be replaced with a 2.5" SATA I or SATA II HD or Solid State Drive of any capacity up to 2TB. Suggest doing an internet search for "Mac mini Upgrade Guide" if you plan to do upgrades yourself. Otherwise go to an Apple Specialist for both memory and hard drive upgrades.


    If Macmini2,1 (2007): Lion (OS 10.7.5) is highest OS supported (if at least 2GB of memory present). Memory can be increased to 4GB.

    If Macmini3,1 (2009) or later: Yosemite (OS 10.10) is currently highest OS supported.

  • If you could upgrade the hardware such as ram, that would be a good idea before upgrading to a new version of OS X. Otherwise, I highly recommending NOT upgrading because it will cause extreme bottleneck and performance to slow down.
