Network Error -1001

Yes - I just had the same problem when I upgraded my Mini to 10.5. Software update was able to connect to the internet and tell me I needed to install a load of updates, but when I tried, I got this; "A networking error has occurred: Cannot open file (-3001). Make sure you can connect to the Internet, then try again."

Clearly this is absurd and likely to lead less-computer-savvy people to want to throw things out of high windows and curse Apple roundly for the stupid contradiction. Apple - please fix this!

A work-around is to go to http://www.apple.com/support/downloads/ - download what you need (listed in the software update window) and install each package separately - I just did that. It takes longer and it's a bit more 'techy' than it really should be - but it does work.

Same thing happens on a dual 2.3 G5 trying Software Update at 10.5.0. Deleted networking prefs and same thing happens. Internet connection is fine. Went to support page and downloaded 10.5.2. No help on restart...same error message.

Hi there,

If your not getting internet connectivity through Safari or Software Update or iTunes as well, but you CAN with Firefox etc.. then it's possible that you have an *invalid web proxy*.

Go to your Dock, open *System Settings*, open Networking, if you're using Airport, Double click your Airport in the list (Show: Airport), Go to the Proxies panel, uncheck *Web Proxy* if it's checked. Click *Apply Now*.

Lastly, click on the TCP/IP panel and *RENEW DHCP Lease*.



I hope this fixes your problem!

I was able to fix my Software Update error -1001 problem by quitting Software Update, then trashing the com.apple.SoftwareUpdate.plist pref file (located in HD>Library>Preferences Folder), then re-launch Software update! Horray!

Hi,

I am getting this error message too when trying to run Software Update.

I'm tempted by Richard's suggestion but am nervous about 'trashing' any files that I don't fully understand.

Could someone advise if this is a safe thing to do - i.e If I copy this file before trashing, and put it back afterwards if this approach doesn't work how much harm could I do ?

Thanks

RIchard's 'trick' totally worked for me. I've been unable to use update for months. Hooray!

Just confirming, along with Linda, that removing the file as suggested by Richard worked for me.

NB - This is a specific fix only for the 1001 error message when attempting to run Software Update on a machine that could otherwise connect to the internet perfectly well.

Many Thanks
