Fresh install of MacOS and OBS still triggers Rosetta install on run

[spm1001]

Sorry if this is silly one - I've not previously used OBS and wanted to go straight to this M1 version.

Compilation completed without error (using M1 version of Homebrew too if that matters.)

On trying to run the newly minted OBS I get the 'To open 'OBS' you need to install Rosetta' dialog so am assuming there's an x86 binary lurking somewhere? Ideally I'd like to live without Rosetta at all.

Tried using file to discover it - seems to be one stray x86_64 for virtualcam which might be the trigger?

% find . * -exec file {} \; > results.out
% cat results.out | grep x86
...
./Contents/Resources/data/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit bundle x86_64] [arm64:Mach-O 64-bit bundle arm64]
./Contents/Resources/data/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam (for architecture x86_64):	Mach-O 64-bit bundle x86_64
...

Removing the plugin from the OBS folder still gives the error but I'm not sure when MacOS interrogates the app to see if it needs Rosetta.

It might be nice if it didn't trigger the Rosetta install but not sure if that's possible.

Thanks for raising this, @spm1001. Unfortunately I can't reproduce this in my environment. Furthermore, I can confirm that VirtualCam is compiled as a universal binary and its object file targets arm64:

/Applications/OBS.app//Contents/Resources/obs-plugins/mac-virtualcam.so: Mach-O 64-bit bundle arm64
/Applications/OBS.app//Contents/Resources/data/obs-plugins/mac-virtualcam/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit bundle x86_64] [arm64:Mach-O 64-bit bundle arm64]
/Applications/OBS.app//Contents/Resources/data/obs-plugins/mac-virtualcam/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam (for architecture x86_64):	Mach-O 64-bit bundle x86_64
/Applications/OBS.app//Contents/Resources/data/obs-plugins/mac-virtualcam/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam (for architecture arm64):	Mach-O 64-bit bundle arm64

Universal binaries will run using the same architecture as its parent process; see here for more information.

Confirm that the shell that you're running ./install.sh from is running using arm64 instructions:

$: arch
arm64

I have the same issue on a fresh macOS 12.0.1 install. All binaries and libs seem to have arm64 versions or bundles, but double clicking the app still tries to install Rosetta. Some interesting messages from console:

error 12:30:59.157670-0700 Finder LAUNCH: User preference exists for x86_64 but runtime support is not installed.
error 12:30:59.157774-0700 Finder LAUNCH: Launch failure with -10669/ <private>
error 12:30:59.158874-0700 CoreServicesUIAgent handle LS launch error: {\n Action = oapp;\n AppMimimumSystemVersion = "10.8.5";\n AppPath = "/Applications/OBS.app";\n ErrorCode = "-10669";\n}

Any idea where this "user preference" comes from or is stored?

Interestingly, launching from the command line works:

That's a weird one. Unfortunately, I'm not sure. You might want to try running fs_usage while you start up OBS to see which plist Finder is accessing here. Strangely enough, I can't find any documentation on that specific error on the Internet.

I have a clean Mac install (installed 1 hour ago!) - I haven't installed anything else yet except for homebrew.

I am running install.sh:

hackeron@Romans-MacBook-Pro obs-installer-for-apple-silicon % arch

When I click on the OBS executable, it tries to install rosetta.

However, if I run it like this, it doesn't!

hackeron@Romans-MacBook-Pro obs-installer-for-apple-silicon % ~/Downloads/OBS.app/Contents/MacOS/OBS

Very strange!

Hey, Roman; thanks for using this! Can you try running this in Bash instead of zsh?
