Software Update FAIL: -1001

Apple – Support – Discussions – Software Update FAIL:.  Are you getting this error message? “A networking error has occurred: timed out (-1001). Make sure you can connect to the Internet, then try again.”

KJK555 suggests this:

Run Permissions repair, if that doesn’t help:
1. clean everything out of the /Library/Updates directory.
if it still don’t work:
2. rename or delete this file:
/Library/Preferences/com.apple.SoftwareUpdate.plist
if it still don’t work:
3. rename or delete this file (in your home directory):
~/Library/Preferences/com.apple.SoftwareUpdate.plist
Last resort:
4. archive and install (unless someone chimes in with more suggestions).

And Carolyn Samit suggests this:

HI,

HD>Users/YourName/Library/Caches com.apple.SoftwareUpdate

Delete this file: Cache.db restart your Mac and see if you can run Software Update.
