This question is about Emacs 27.2-2 from https://emacsformacosx.com/ on Mac M1. From the release notes1 M1 support should be added since 27.2-1. However, on latest stable version I was getting an error "This application will not run on your computer. Sorry!". How could I get it run on Mac M1? What was the condition that could throw this error? Thanks.

  • It won't open for me either. It tells me "“Emacs.app” is damaged and can’t be opened. You should eject the disk image." :-( – amitp May 12 '21 at 15:16
  • I finally went back and tried 27.2-1 and found that it was working fine on Mac M1. Maybe you could also try and see if it works? – timcoding May 12 '21 at 16:47
  • I wanted to follow up on OP's question from six months ago. Does Emacs 27.2-2 from https://emacsformacosx.com/ work on Mac M1? – midas0441 Nov 11 '21 at 11:17
  • From a brief test, 27.2-2 seems to work on M1. Maybe this thread should be marked resolved? – midas0441 Nov 13 '21 at 13:05

    27.2-1 works, but 27.2-3 gives the same error: "This application will not run on your computer." Regression or something? – Owen Mehegan Feb 15 '22 at 05:08
  • I could not get any of 27.2.{1-3} (or `homebrew/cask/emacs`) to work on mini M1 Big Sur. "This application will not run on your computer" or crashes. Finally I upgraded to Monterey - emacs is that important to me - and was able to install successfully. – Gordon Apr 02 '22 at 20:21

This same thing happened to me where using v27.2-3 on an M1 mac gave me the This application will not run on your computer. error; however, when I uninstalled the cask and reinstalled the normal formula which at the time of this writing is 27.2, it ran correctly for me. Would love to see the Emacs team patch the Cask version to run properly on an M1 Mac.
