Same here. Using UE 5.4.4 with macOS Sequoia and Xcode 16. Sometimes a bunch of UE instances spawn in the Dock and I have to force-quit all of them. Also, packaging gets stuck on ‘processing assets’ unless the Output Log window that appears in the background is manually closed.

So is there a ticket for this I really dont wanna roll back. I knew I shouldn’t have updated. Have the made any updates since the MacOS update I have been away for a bit.

The OP of this thread says they were running Sonoma 14.4.1 back in April, for UE 5.3.

For me, I have not upgraded to Sequoia. I responded to this thread in May with my specs. I was having the same issue on Sonoma 14.4.1, with UE 5.4.2, and still now (October) with Sonoma 14.7 with UE 5…4. Still super annoying.

Looking back above when Sequoia came out, looks like other folks were/are having the same issue. So, it seems it was definitely an issue prior. And apparently for folks who weren’t having the issue before have now joined the club.

Sigh.

I only raised a ticket for the hanging packaging process, that is obviously related to this issue. There’s no response yet from Epic.

Same issue. Twinmotion will not quit, and has to be force quit everytime. Also, my laptop will not shut down if Twinmotion has not quit. Started happening with Sequoia 15.0.

Same issue on Mac Studio M1, up to UE 5.5 Beta. Raised a bug about packaging issue too. Unsure how to bring stronger awareness to UE team rather than opening a bug that doesn’t seem considered.
However packaging works well from terminal. I can share the command line if anyone needs it.

It seems to be related with the background cooking process not ending properly.

I’ve done some tests with CookProcessCount=4 on my Mac Studio. The cooking times are significantly reduced (from 6 minutes to less than 1 minute on a simple project), which is great. But I need to manually end each cooking task by closing its associated window. Then the packaging process continues and completes successfully.

I was hesitant to update to Sequoia, now I regret it as I have the same problem. No solution - just adding to the list of complainants!

Same here, running on MBP M3 Max, 64GB, Sequoia 15.0.1

I’m new to Unreal Engine. So far everything else seems to be running sweet.
