Do Mac OS apps stop working if your Mac Developer ID Application cert expires?

I’ve done lots of test deployments to devices that are registered in my wildcard provisioning profile. After the cert expires the app no longer runs on the test devices. You have to renew the cert and provisioning profile, re-save and reinstall the app on the device if you want it to work again.

I don’t know if it is different if you are distributing with an app-specific provisioning profile, since I haven’t tried that.
