Hey fellow Mac users. Anyone got UE 5.3.1 running on Sonoma? Any problems, hick-ups? Thx!

OK. Sorry to hear. So you are trying to open an older project (5.2?) and it crashes? What if you create a new project? Still crashes?
Currently all my packaged builds under 5.3.1 are 300% bigger in size than before or than in Windows.

WTF. Have you also updated Xcode? Any observations performance wise?
Everything’s updated. Performance seems the same. Digging into the files project seems duplicated x3, no idea why, but honestly don’t think it’s worth the effort. Clear coat was broken for almost a year in Mac and nobody seemed to care about it, not when it was broken and not even when it was randomly fixed in 5.3, so whatever.
For reference this is my original post MacOS 5.3 build is 300% larger than 5.1? - Development / Platform & Builds - Epic Developer Community Forums (unrealengine.com)
Yeah, it seems like we Mac users are the step children. I get it though, Apple has a long way to go hardware-wise. It is just curious to me why they would put so much effort into porting the engine in general but then half-assing it on the last meters. I am still happy they do. I am just playing around with unreal engine and need a Mac for my work. So a PC is not option.

Hey, I have a 5.1 project and updating (forced) to Sonoma broke the dotnet6 dependency. I cannot build any sourcecode. (Made sure xcode and dotnet are up to date, but it simply fails, claiming that the Platform SDK is not installed properly.)
Is there any fix or workaround?
(Last Intel based Mac, non-M based.)
Under Platforms/‘Content/SDK/Device Management’/mac/SDK management. It shows this
Of course only 15 is supported on Sonoma.

Is there a solution?
I’m no m3pro and Sonoma and when I try to update device I get:
UATHelper: Installing Sdk (Mac): ERROR: Mac: Unable to find any Sdks that could be installed
So I cannot package anything…

Someone on my team was having this same issue when trying to boot our VR project. This fixed it for him,
in Config/DefaultEngine.ini, turn off r.ForwardShading
r.ForwardShading=False
