It has always been easier to run third-party software on a Mac than on an iPhone or iPad. Despite the introduction of the Mac App Store a couple of years after the iPhone’s App Store opened, it has always been possible to download and run third-party scripts and software on your Mac from anywhere. It’s one reason why the iPhone and iPad are subject to new European Union regulations about software sideloading and third-party app stores, while the Mac isn’t.

That’s not changing in macOS 15 Sequoia, the new version of macOS that’s due to be released to the public this fall. But it is about to get more annoying for some apps, according to a note added to Apple’s developer site yesterday.

“In macOS Sequoia, users will no longer be able to Control-click to override Gatekeeper when opening software that isn’t signed correctly or notarized,” the brief note reads. “They’ll need to visit System Settings > Privacy & Security to review security information for software before allowing it to run.”
