Xcode 11.3.1 update isn't downloading

I just let it run - took overnite+, but it finally finished. Lots of devs doing the same thing right now, so...

I tried rebooting and the problem persisted. Then, I logged into my apple developer account via the web and notcied there was a banner saying 'Our terms have changed ... yada yada ... you must accept them'.

Then I returned to the laptop, rebooted again, and the circle with no progress with the square in the middle was gone and Xcode was fully updated - the problem seems to have been with the download progress indicator not reflecting reality - because there is no way it downloaded the 7.8GB that fast.

This has been happening for years with big apps (FCP, Logic, etc), sometimes I see similar behavior in the podcast app on iOS too. Doesn't seem to be a priority for them to fix it.

Interesting on accepting the new terms and conditions. I have checked & accepted that (sometime in the last week or so).

I had disabled System Integrity Protection (SIP) to develop and test my own endpoint daemons. Today I re-enabled SIP and removed my daemons, the software update proceeded.

So... I don't know if it was a SIP issue or a Terms & Conditions issue, but it is working for me now.
