"An error occurred while installing the selected updates."

Still giving me error on 3 different machines, 2 of which are on different ISP's.

 

[mauriciorp]

It is the same for me. Not resolved!

 

[udontno]

Same for me. Gonna restart the computer and see if that makes any difference.

System status green, no joy in Mudville.

 

[appletvbob]

Force quit system preferences and restart. Nope. Every trick in the playbook all for naught.

On both of the MacBook Pro's in our household clicking Upgrade Now gives us an instant error. I'll try again in a couple hours.

 

[Ve0]

Still have the error

 

[Dominat0r]

Apple tech "How about we just turn the light green?" Apple tech manager...."Sounds good"

 

[MattyK-USA]

Rebooted, still no love.

Maybe should write a little cron job to try every 10 mins or so...

 

[cobra521]

Same error here - I'll guess everyone who has a Mac is trying to get the 12GB file. Meh...

This morning I was ready to get Big Sur but instead I got a Big Sur-prise 😭

 

[xpinit]

Pity Apple finds the need to lie on their system status page when the issue is clearly still occurring. Bad customer service Apple.

 

[xpinit]

Y

Apple tech "How about we just turn the light green?" Apple tech manager...."Sounds good"

Lol yeah, probably something like "Screw the customers, the execs will be watching the status page and toast us... better lie and say it's all fixed" allegedly of course

 

[runnoft]

Now eventually, you'll be able to upgrade after selecting the "Upgrade Now" button, right? Hello? Yes?

"It just works..."

Remember the good old days?

Using Proxyman, I can see that Software Update is trying to download from http://swcdn.apple.com/content/down...x1n2wpf8rik5agns2z43ikqu/InstallAssistant.pkg but getting a 403 error from the server.

 

[dmccombs]

"It just works..."

Remember the good old days?

The current reality is "It just barely works..."

 

[wilsonlaidlaw]

Apple claim on their status page that the update download fail issue is fixed - WRONG.

 

[SuperFluffyBunny]

Look in "Console" app --> "Log Reports" --> "install.log"

NSURLErrorDomain Code = -1100 (File Doesn't Exist), with a PKURLTransportError = 503 (Service Unavailable)

Note - this is a CDN Apple uses to distribute updates, Apple pulled it from some CDNs, but not all.

 

[moebis]

Apple left themselves open for it: Bug Sur

 

[hatchettjack]

got to love apple! it just works could not be truer

 

[zeropointzero]

I rushed here to MacRumors to confirm I am not the only one with the issue.... looks like the majority of us are getting the same error. bummer for my iMac Pro.

[dvdhoo]

Apple says it has been resolved. Nope, still error.
