Apple Removes Ability to Run Unsigned Apps in macOS 15.1 (opens in new tab)

Funny, there were no notes or warnings about this when I clicked “update now” and of course, OS updates can’t be rolled back… Not sure what Apple is doing here but it sounds rather evil.

The Author didn't check if they have a unique problem ... it it seems they have an individual issue. Which is still shit, but not the kind of suggested by the alarmist headline.

I checked my version, it its 15.1. on a M2 Macbook Air. Its fine. Same for at least 3 other people I asked and which checked.

Wow, I guess I'm never upgrading to that OS version or buying more Apple hardware for development when this puppy dies.

I haven't found much information about this online. One YouTube comment claimed Apple has only removed the ability to launch unsigned apps via right-click, but you can still open them deep in the setting menus.

This claim does not appear to hold water. Works fine for me on both an M1 Ultra Mac Studio and M2 Max MacBook Pro running macOS 15.1.

Seems like it’s just a bug that the author is experiencing.

Apple removing the ability to run unsigned software entirely would footgun Mac sales. No way they would do that.

Hopefully just a bug. If not, Apple should be ready for more expensive legal battles (at least in the EU).

Hasn’t affected me. And I use a bunch of homebrew installed software.

The error message shown on that blog looks more like a bug than a policy message.

Is the brew ecosystem impacted by this?
