OK, the "Checking for Updates" ran through a lot faster with the LAN cable than over WiFi, and it is now really installing. I have hardwired LAN for all the desktops, except this one that is at a corner without a jack. ...
Are you getting a weak wifi signal to that computer? Even the older versions of wifi are generally faster than most peoples internet connection, so they should not be a bottleneck. Unless you have super-fast internet, and very old wifi?
Something does not seem right.
I thought running the installation off a DVD would not require much Internet download, yet it was so painful. Wonder how much patience one would need to do everything over a WiFi.
My experience with other OSs (OSes?), Mac and Linux, is that the DVD is generally out of date enough that there are many, many updates to download. The DVD install may not save so much time.
This really aggravated me when I went to do a major upgrade to my Mom's mini-Mac. She had a fairly slow connection, and I wouldn't have time to do the download and install while I was there. I found Apple had some sort of 'combined updates' (I forget their term for them) that you could download, so I did that at home, and saved the 'combined update' to an external hard drive, and took that over to her house. Should have been a quick install.
Well, boot up and it's giving me security warnings, says it really needs to make xyz update... OK. But then of course, that update requires another update and a reboot, and that update requires another update and another reboot, and on and on... very frustrating.
I complained on the forums that Apple should keep these 'combined update' files more up to date (it was ~ 6 months old, with several large xxx MB updates released afterwards ), or they don't help much. You'd have thought I said bad things about Steve Job's mother! All the rationalization of why this is a perfect system, I should get fast internet, update every time one is available (trust me - you don't want to throw every update at a 'frail' computer user!), etc, etc
It's often a mess.
