I am using a m1 MacBook Pro and do not want any intel applications. Therefore all apps I install are either universal or plain arm64. But rosetta2 is still activated because ms office 2019 which updates itself to arm version later is distributed in intel binary. After that, all apps I use are native.

However, the 'CarbonComponentScannerXPC' exists as the only process with Intel code. The Activity Monitor tells me perhaps it is from the AudioToolbox framework. I search on the Internet but cannot find more information. Can anybody tell me what purpose it serves? Is there any way to remove or stop it?

  • I have this process too, and like you want to nuke it. I don't know what's causing it to execute.

  • If it's part of the OS, then leave it alone. It could perhaps be something that Rosetta runs inside itself. Incidentally, I downloaded Office 2019 from an MS support page, and it was UB.

  • @benwiggy R2 is a binary translation engine, one shouldn't see arbitrary Intel apps running. Moreover, the parent process is AudioComponentRegistrar.

  • @benwiggy My office is offered by my university, which unfortunately is an earlier intel version.

UPDATE:there is no clean way to disable Rosetta 2 after enabled you can disable SIP and then remove files. https://developer.apple.com/forums/thread/669486

this process comes with Rosetta 2, and if enable Rosetta 2 the process named CarbonComponentScannerXPC will always start after boot

  • Why? It wasn't there in BigSur.

  • Act like a new feature on Monterey, now is removed on Monterey 12.1

    Does CarbonComponentScannerXPC cost anything? (e.g., excessive CPU cycles). And is there a way to disable Rosetta 2?

Did you install Homebrew? I found that after installing Homebrew (even though it said it was made for the M1 chip) my MacBook Pro also has the CarbonComponentScanner process. After resetting my MacBook Pro to factory again and installed all my apps, except Homebrew, everything was back to Apple processes only.
