So my fiancee 13" late 2008 air finally arrived, two days late! Thanks Hermes! Anyway it is a 1.6 Core2Duo with 2GB ram and 128GB SSD. It is in ok condition with screen bezel lifting at base where meets body but overall good for age. It arrived running mavericks but decided to upgrade to El Capitan. So downloaded El Capitan, oddly search of app store it not there but google it and go via apple support page, which redirects me to app store and there it is. So hour to download all ok. The install hung at 29 mins to go, started with 31 mins to go. So powered off then restart, this time go to 15 mins to go, after 45 mins I turned it off and went bed as was little after midnight. Gonna try again later after work. Any idea what going on? --- Post Merged, Nov 25, 2016 --- Well my fiancee at home decided to try while I'm at work. Took hour and half but El Cap went in.
