can someone explain gb usage when updating
if your macbook has 2 gb memory and 250gb hd and you have SL and want to upgrade to Lion or Mtn Lion or Mavericks BUT they require 2gb memory to upgrade to...does it use all of the 2gb you have? in other words you have 2gb it requires 2gb so your are left with zero gb because you upgraded?
Note, I am sure this is dependant upon how much stuff you have on your mac as well...for me mine is new and has nothing trans from my pc yet!
Anyone??
MacBook, Mac OS X (10.6.8), 2010 MC516LL/A 7,1 Intel Core Duo
