By unused, I mean the green colored piece of pie in Activity Monitor.
If you want a 3 or 4 gig virtual Mac, you'll need about that much space unused on your Mac.
The one thing you'll need is memory (RAM). I think of the real Mac like I do my home, with personal property, while I think of the virtual Mac as my office space, my cubicle, having only work-related items. All my own personal stuff is kept to the real Mac. This arrangement has many advantages, including resisting the pushing and shoving of Apple to constantly upgrade our OS, Xcode, and iOS targets.Īnother advantage is a pristine working environment with its own clean Keychain, Desktop, and so forth having only items related to Xcode project(s). To answer your question, 'Any suggestions?': Use a virtualizer like Parallels, Fusion, or VirtualBox to run Lion, Mountain Lion, or Mavericks in a virtual environment. Tip: If you are looking at picking up older devices, you'll want to target iOS 4.2.1 not 4.3, as every device supporting 4.3 can be upgraded to iOS 5. Ignore the snarky comments by people like matheszabi there are good reasons to support the millions of units of older devices.
