macOS 14 jobs hanging on security remove-trusted-cert command

[djc]

Description

I've written up the issue in some detail in rustls/rustls-native-certs#179.

Repeating some salient bits here, this script (executed with sudo) ends up hanging:

+ ANY_CA_PEM=integration-tests/one-existing-ca.pem
+ ANY_CA_SUBJECT='OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
+ security authorizationdb write com.apple.trust-settings.admin allow
YES (0)
+ reset
+ security remove-trusted-cert -d integration-tests/one-existing-ca.pem
SecTrustSettingsRemoveTrustSettings: The specified item could not be found in the keychain.
+ true
+ list
+ cargo test util_list_certs -- --nocapture
+ grep 'OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
cert[95] = OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign
+ test_distrust_existing_root
+ assert_exists 'OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
+ list
+ cargo test util_list_certs -- --nocapture
+ grep 'OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
+ security add-trusted-cert -d -r deny integration-tests/one-existing-ca.pem
+ assert_missing 'OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
+ set +e
+ list
+ cargo test util_list_certs -- --nocapture
+ grep 'OU=GlobalSign Root CA - R3, O=GlobalSign, CN=GlobalSign'
+ ret=1
+ set -e
+ test 1 -eq 1
+ reset
+ security remove-trusted-cert -d integration-tests/one-existing-ca.pem

It seems to have worked on macOS 14.7.4 runners (image 20250331.1204) and failed with macOS 14.7.5 (image 20250421.1374). I since also noticed #11893 which suggests that our script might stop working in macOS 15, but since this is still on macOS 14.7 I'm not sure if that is related to the current failure.

Successful run, failed run.

(Previously discussed in #4734.)

I have started having issues running security add-trusted-cert .. without sudo. Currently macos-latest runs macOS 14.7.5. Adding sudo solved the problem.

[djc]

To be clear, our project is already using sudo (but one level up, in executing the script).

Hi @djc, We are currently waiting the vm rollout of new macOS 14.7.6 runner. The updated version is already available in the macos-latest image level, but it's deployment is scheduled for next week due to MSbuild deployment freeze this week. We appreciate your patience and will notify to you as soon as deployment is complete. Hopefully, your issue will be resolved once macOS 14.7.6 available.
