The drawbacks of virtualisation is the cost and performance.

Being a Mac owner, you are spoilt for choice with VMWare Fusion, Parallels or Virtualbox. This means that I can test the features and functionality of OS X Mavericks without compromising my every day working with OS X Mountain Lion.įor many people, virtualisation is the answer and this generally works well. It runs alongside, but completely separately from, OS X Mountain Lion. This is especially true if your Mac is your only computer.įor example, by partitioning my Mac’s hard drive, I have been able to install OS X Mavericks as a separate installation.

The great thing about Macs (and Apple products in general) is that they usually retain their resell or trade-in value fairly well compared to other machines. MacBook Air and Pros on top of each other side view (Image credit: iMore)
