Expiring Developer Certificates Causing Some Mac Apps to Refuse to Launch – Mac Rumors

A number of Mac apps failed to launch for users over the weekend because of a change to the way Apple certifies apps that have not been bought directly from the Mac App Store.

Uh, okay.

Victims of expired provisioning profiles over the weekend included users of 1Password for Mac who had bought the app from the developer’s website. AgileBits explained on Sunday that affected users would need to manually update to the latest version (6.5.5), noting that those who downloaded 1Password from the Mac App Store were unaffected. The developers’ surprise was explained in a blog post:

“We knew our developer certificate was going to expire on Saturday, but thought nothing of it because we believed those were only necessary when publishing a new version. Apparently that’s not the case. In reality it had the unexpected side effect of causing macOS to refuse to launch 1Password properly.”

Here’s more on this issue from TidBITS.

  1. You are probably confusing development and distribution certificates. The document you’ve linked to talks about expired development certificates. Which are not the same thing as the Developer ID Application certificate (a.k.a. one of the distribution certificates).
