Just bought a MBA this past week and it has Lion installed (10.7.4) and am supposed to download ML 10.8 within a certain time frame (30 days) or I'd have to pay for it. I have a few programs that I am not sure are 10.8 compatible and do not want to upgrade to 10.8 until I know for sure. I was sent the download code in an email after submitting my "UP TO DATE" claim but did NOT download yet until I know for sure what I need to do in order to download but install at a later date. So.....will it allow me to download but not install? Or do I have to find where it downloaded and save it somewhere, etc? (i.e., much like when Lion came out for SL users and it was saved to a jump drive, etc). Thanks for any replies in advance!
