How does that explain why some people have been able to install the 15.4.1 update on their Studio Display? And if 15.4.1 isn't intended for the Studio Display, users shouldn't be shown an alert saying an update is available. It's also unclear what 15.4.1 does for the display. For iOS, it was mostly about patching security vulnerabilities. Does that apply to the Studio Display too?
This seems most likely to be correct. I know these things happen, but it makes Apple look bad. It's probably a privacy issue within Apple, and the groups who should have planned this out didn't know about each other.
What’s the version number of the update you were able to install on your ASD?
Display Firmware Version: Version 15.4 (Build 19E241); Before apple stopped signing 15.4 ( a week +ago)
OK, thanks. I mistakenly thought you had installed the newer update. Hopefully, Apple will get this sorted out soon. Or at least before my SD arrives.
Nope. I successfully did the update to Display Firmware 15.4 (Build 19E241) a while ago using an M1 Pro MBP connected via Ethernet. At the time I did the update (I'm thinking it was within days of getting the Studio Display), my MBP was running v 12.3 not 12.3.1 of Mac OS. So it's not Apple Silicon vs Intel because my Apple Silicon MBP did the update fine.
Nope on both. It failed even before I updated to 12.3.1 while I was on 12.3. I also tried via ethernet as well with no luck. This is an Apple server issue that they have still not resolved from the looks of it.
Thanks for the additional details. It's good to know what variables have been ruled out.
Yes! I just went and checked. It downloaded and installed. I’m officially on version 15.4!!
When the restart countdown started for me I just hit restart from the countdown window instead of waiting. It restarted immediately. Then the 3 dots came up on the monitor and a notice it was updating and not to unplug it. Took about 8 minutes to go through the whole process.
