When running setup command on an M1 arm64 mac the dependencies fail to download.
This issue is occurring in Github //UE5/Release-5.3 @ CL 26560699
This issue is NOT occurring in Github //UE5/Release-5.2 @ CL 26001984
Marked As Regression
Workaround for the issue is to remove line 13 of Engine/Build/BatchFiles/Mac/GitDependencies.sh and run /Engine/Binaries/DotNET/GitDependencies/osx-x64/GitDependencies
Setup.command process completes without downloading dependencies.
Dependencies are downloaded
