Intermittent failure in code signing on Mac Mini

[macumber]

Issue overview

The Mac Mini ARM64 is failing intermittently around code signing operations

Current Behavior

I have seen two failure modes:

1. Failure in "Configure for codesigning"
   https://github.com/openstudiocoalition/OpenStudioApplication/actions/runs/13744554223/job/38437897985

A new keychain file (the /_work/_temp/ directory is wiped clean for each build) is created but import of the DeveloperIDG2CA.cer fails because it already exists in the keychain

• security import AppleWWDRCAG2.cer -k /Users/irvinemac/actions-runner/_work/_temp/app-signing.keychain-db

CPack Error: Problem compressing the directory

Inside that log file is

Critical: Failed to sign app bundle: running codesign failed with exit code 1: error: The specified item could not be found in the keychain

Expected Behavior

The code signing should work repeatedly without fail.

Steps to Reproduce

It's possible that running CI actions back to back cause this behavior to switch around? The call to security unlock-keychain unlocks it for 6 hrs (due to potential for long builds). The call to notarytool store-credentials says it imports the profile to the default keychain. It's possible that these unlock times and interaction with the default keychain cause issues?

Possible Solution

Can we use a keychain file for IFW CodeSigning.cmake and not the default keychain?
Do we need some always run GitHub workflow steps to clean up keychains for future runs?

Environment

Some additional details about your environment for this issue (if relevant):

• Platform (Operating system, version):
• Version of OpenStudioApplication (if using an intermediate build, include SHA):

Context

Have to continuously re-run the Mac actions to get them to work.
