Re: Installer pkg built with Xcode 12.2 won't open in macOS 10.10 and 10.11
I've had similar problems when code-signing and notarizing an app using Xcode 12.2 on Big Sur.toggle quoted messageShow quoted text
On my DTK (Apple Silicon) machine running macOS 11.1 beta and Xcode 12.2, if I go through a standard build and notarization using the Xcode GUI, everything appears to be fine. The codesign and spctl commands report everything is fine when I run them on macOS 11 or 10.15 and the app launches as expected. However, on macOS 10.10, I get the error "the sealed resource directory is invalid" when I run spctl and the system refuses to launch the app, saying it's damaged.
However, if I build on my MacBook Pro running macOS 11.1 beta and Xcode 12 beta, the resulting app doesn't have any problems. I'll boot back into Big Sur and find out which Xcode 12 beta I'm running. In any case, I'm hesitant to update to Xcode 12.2 for fear my builds will no longer work on 10.10.
