Description
Description:
Problem
setup-python fails on self-hosted macOS EC2 runners with:
Error: ln: python314: Permission denied
The setup.sh installer script uses sudo to install the Python framework into /Library/Frameworks/ (line 50), but the subsequent symlink creation inside that root-owned directory runs without sudo, causing a permission error on runners where the CI user is not an admin.
Action version:
v6
Platform:
- Ubuntu
- macOS
- Windows
Runner type:
- Hosted
- Self-hosted
Tools version:
Any
Repro steps:
Make a deployment on a MacOS instance where the runner is running as a standard user with sudo permission.
Expected behavior:
The installation process creates symbolic links without failures.
Actual behavior:
Fix:
Can be addressed by this PR: https://github.com/actions/python-versions/pull/384

Research direction
Review setup.sh around line 50 and the referenced pull request in actions/python-versions#384 to understand the installer and symlink steps. Reproduce the setup-python v6 installation on a standard-user macOS self-hosted runner, then confirm that symbolic-link creation completes without a permission error.
