I have two Macs, desktop and laptop. Since they both belong to me, they both sign in with the same Apple account. I find that if I sign and notarize an app on one, the other must be powered off. Otherwise, notarization will fail.
Is this intentional? If so, what is the rationale? Is there a way to fix or avoid it?
Both systems run macOS Tahoe with the latest updates. Both are set up the same way for signing using the same certificates. The build process is identical on each.
