Is a macOS installer I've made with createinstallmedia on an Intel-based Mac bootable on an M1-based Mac?

    Have a look at: How to create a bootable installer for macOS. My read on it is as long as the hardware supports the version of macOS on the USB Installer it should work. Sep 7, 2021 at 18:03
  • right, thank you, I'm just unsure as to whether or not apple transparently downloads you an apple silicon exclusive variant when downloading from an apple silicon mac, and vice versa on an intel mac. will test my installer soon and post back here

    Eric Reed, The reason I posted what I did, as a comment, is I'm not 100% sure. My guess it that's what the whole universal binaries are supposed to be about. In any case, after you've tried and definitively know, you can self-answer your question. Sep 7, 2021 at 23:19

The macOS installers are compatible with both Intel and Apple Silicon (M1, M2, etc.)

How to Verify

Here’s how I verified it:

On an M1 machine (running macOS Ventura):

  • Went to How to download macOS and srolled down to “Or use the App Store or your browser”
  • Clicked Monterey 12 to download it via the App Store
  • Created USB disk using /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/$VOLUME_NAME

On an Intel machine:

  • Booted from the USB disk
  • Installed Monterey
