[anticipate]

Finally working in Massachusetts

EDIT: Nope. It started and then failed. But we are making progress. Apple really messed up today lol

EDIT 2: waited a bit; working.

That was nice while it lasted... download like 2GB worth in 5 minutes span and I am getting the error again. At least it's working sometimes...

 

[p8blr]

I managed to get it to download a few more gigs but it just errored out again at 5GB...

 

[JAdmiral]

Still not working in SoCalif.

I waited this long. Best to wait until tomorrow.

Got up to about 9gb now it crashed again. Same error.

If you are getting "An Error Occurred While Installing the Selected Updates", do the following:
1. Launch the terminal
2. Run `sudo killall -HUP mDNSResponder`
3. Retry update

I'm going to wait until tomorrow and try again.

 

[Samuel Sosa]

OK...mine crapped out at about 7gb downloaded. And I'm back to the same annoying error message.

try the terminal command sudo softwareupdate --clear-catalog

It seems to be working

You are up late across the pod.

I’m a bit of a night owl at the moment

I tried again and it's resuming where it left off. Los Angeles / no VPN

 

[NoImDirtyDan]

Refreshed system update by using the App Store link, making progress

Edit: error continues

Edit: Restarted and download is moving

Edit: Full stop at 4.xx GB

I don't get it I download the first 4GB in 20 seconds and it just stops at 4.38 every time

Update pushed through now....download speeds spiking up and down randomly. Hopefully, it goes through

12.18/12.18....waiting on installer to show up.

Failed with new error "#@" missing or invalid redownloading, speeds are very slow now

Finished downloading finally!

 

[jeff6666p]

just failed

 

[Phil77354]

Stuck at 2.88 GB.

Just failed again.

If you are getting "An Error Occurred While Installing the Selected Updates", do the following:
1. Launch the terminal
2. Run `sudo killall -HUP mDNSResponder`
3. Retry update

Was consistently giving me the error, just did that and now it's already up to 7gb.

I tried a bunch of VPN locations. Worked for a while and in all cases eventually failed.

Well this is interesting. My software updates suddenly claims I have no internet and that my updates are managed externally.

I'm in Riverside County, no VPN -- 20 min to go.

My mac picked up a Safari update.

update: it's downloading perfectly fine.

 

[Dangermen]

When on a VPN, can anyone look at a ’netstat -an’ or an ‘lsof -Np‘ to see what IP address range the connection is being formed to?

 

[CosmicDog]

Pathetic.

Netflix, etc, can handle the load when a new movie or TV series is dropped. You'd think Apple would've figured this out by now.

Netflix stages servers directly at most ISPs in high-usage areas. I don't think Apple would do the same for (roughly annual) OS updates.

 

[steveaburns]

Downloading, no VPN -- US, west coast.

stopped, and won't restart.

Apple is starting to be as bad as Microsoft. Ughghgh

Huh, not even close.
I use win10 and OS X every day. trust me. xD win10 is imho the best windows but OS X is great in compare to that

 

[decypher44]

Still not working for me (SoCal). It did prompt me to upgrade to the latest Safari browser. That was weird.

Hey guys, can confirm that it's possible to START the download using a VPN on an Australian server, and disconnect the VPN a minute later, getting a huge speed bump on the download.
