Hi, I am new here and need help upgrading my iMac7,1 10.6.8 to 10.9. I only have 1gb memory and modified the one OSInstall.mpkg to support only 1gb. When I booted to installer it said 2gb required. Clicked ok, and was installing, until when it said, Remaining time, 5 minutes and froze, nothing moving. Tried mouse did not work. I am going to leave the imac overnight. Btw, |I checked the logs a few times before, and got a few errors, such as Missing CoreServices etc. and other stuff.
