OS X 10.8.3, wireless internet connection.
An attempt recently to update the OS on my mac to OS X 10.8.4 via the App Store indicated a consistently shifting range of time to do so--2 hours being the shortest and 14 hours(!) the longest.
When it seemed like the time to do the job would be 14 hours, I force quit the process. (This was but one of the total number of updates available to me; had I chosen to update them all, would it have taken days? A lifetime?)
1. Is the long update time due to the wireless connection?
2. Is there a way to expedite the process?
