I am trying out the new xcode 16, and am trying to sign some existing apps. I have a .developerprofile from xcode 15. But I cannot find a way to import it (I think I need the private certs, in order to sign an app). There is no "import" button at the bottom of the Accounts tab, within the xcode Accounts Settings.... Is there any other way (e.g: Terminal) to import an existing .developerprofile into xcode? Or am I missing something?

Odd one here. I'm having trouble getting a signed, notarised, stapled app to actually run. It is packaged as a zip file. When uncompressed and run from finder, I get "“iShowU Switcher” cannot be opened because the developer cannot be verified." and "macOS cannot verify that this app is free from malware." (this is publicly available, https://shinywhitebox.com/download-thanks/17/1 - app is called iShowU Switcher, currently in development) Here's what I've checked: signed codesign --verify --deep --verbose iShowU\ Switcher.app iShowU Switcher.app: valid on disk iShowU Switcher.app: satisfies its Designated Requirement notarized spctl -a -t exec -vvv iShowU\ Switcher.app iShowU Switcher.app: accepted source=Notarized Developer ID origin=Developer ID Application: Shiny White Box Limited (PMJ275ZTUX) stapled xcrun stapler validate iShowU\ Switcher.app Processing: /Users/neil/Downloads/iShowU Switcher.app The validate action worked! So it all looks sane to me. If I remove the quarantine bit (xatter -d -r) then the app runs fine. Ideas of where to next look?
