Hi Fendzilla,
the problem you’re experiencing is documented here Unreal Engine Issues and Bug Tracker (UE-97265) and it’s considered resolved upgrading to UE version 4.26

It would help to know a little more info: what’s your OS version? What Unreal Engine version are you using?

There’s a topic from Jul 2020 here in GameDev forum about a very similar issue:

Unreal Engine Build Failed (Missing Library)

After an update to my MacBook Pro, I found Unreal Engine unable to build any project. Any time I start up a project, it complains that /System/Library/MultitouchSupport.framework/Versions/Current/MultitouchSupport is missing and fails to build the project, immediately closing. Here is the build log: Running bundled mono, version: Mono JIT compiler version 5.16.0.220 (2018-06/bb3ae37d71a Fri Nov 16 17:12:11 EST 2018) ~/Applications/Unreal Engine/UE_4.25/Engine ~/Applications/Unreal Engine/UE_4.2…

Hi Arilal,
Thank you for your reply.
I tried running it on different versions of UE, 4.22.3 4.25.4, 4.27.2. all gave the same error.
my mac is running the Monterey version 12.0.1.
I will try working my way around it with the link you have shared. if any additional information is available please let me know.

Are you sure it’s exactly the same for 4.27?

After trying to update Xcode and connecting the git, 4.27 worked on bull cow. Thank you for your help! I’m back on track now
