Go to System Preferences (under the apple) and Software Update is about the middle of the “Systems” line. On the bottom of the Pref panel for SW Update there are check boxes for checking automatically and downloading automatically. If you spend any significant amount of time attached via an expensive or slow connection, turn them both off.
I would turn off “download automatically” under any circumstances — when you are trying to do something and it runs really slowly, it’s pretty frustrating to realize that it’s because your computer was downloading 500MB of printer driver updates for a printer that broke and you threw in the trash two years ago!
Me too. I’m running a mid-2010 Mac Mini with 8GB RAM.
The first couple of times when I tried using the Software Update app, I couldn’t get the download to begin; after I clicked the Agree button, the dialog box closed, but the download never started. The Software Update app was still running, just not doing anything. I’d close the app and tray again with the same results.
Today I tried and the download did download and started to install. When it reach the ‘Registering components’ stage near the end, it appeared to hang at around 98% complete.
Because I was doing onther stuff on my computer, I let it sit there for about 40 minutes. Then, all of a sudden, it finished the install. I’ve opened iTunes and the ‘About’ box tells me I’m running iTunes 10 .4 (80) 64-bit.
My machine acted a little strange after the update as well. The menu bar at the top didn’t fill in with color. Once I clicked on it, it appeared normally and has been normal since. However for this person, it seems software that needed updating first was the cause. MacMastery has the answer.
