"Out of Application Memory" Error MacBook Pro (retina) [Mavericks]
It's difficult to recommend a straight-forward solution, but here are some things I would do to isolate/resolve the issue:


Open your Activity monitor in Utilities and look at the memory tab/Load.
Use another browser (Firefox, Chrome) to see whether the problem is related to Safari
Log in as another user (create new account if necessary) and try from there to see whether it is account-related
Quit Safari and delete ~/Library/Safari/Downloads.plist
Last not least check your download source (link) for the VMware Fusion 6.0
