macOS 15 is now the default macOS version for GitHub Actions runners

The depot-macos-latest label now runs with macOS 15 (Sequoia) by default, giving you access to the latest Apple development tools and SDKs for your GitHub Actions workflows.

If you need to pin a job to a specific macOS version, you can use:

• depot-macos-15 for macOS 15 (Sequoia)
• depot-macos-14 for macOS 14 (Sonoma)

Both runner types use M2 chips with 8 CPUs, 24 GB of memory, and our disk accelerator for faster I/O operations.
