The difference between "arm64-darwin-23" and "arm64-darwin-22" indicates the version of macOS. These identifiers are used for Mac computers with Apple’s M1, M2, and M3 chips.
- arm64: This denotes the CPU architecture of Apple Silicon chips.
- darwin: This is the name of the macOS kernel.
- Numbers (22 and 23): These represent the major versions of macOS.
Specifically:
- arm64-darwin-22: Corresponds to macOS Ventura (macOS 13).
- arm64-darwin-23: Corresponds to macOS Sonoma (macOS 14).
These differences mainly affect the development environment and software builds. Package managers like Bundler use these identifiers to install the appropriate versions of libraries or gems.
Developers usually address this issue by:
- Adding a platform: Using commands like bundle lock --add-platform x86_64-linux
to add the necessary platform.
- Universal specification: Specifying all macOS versions as universal-darwin
to avoid version-specific issues.
Each time a new macOS version is released, a new platform identifier may be added. Developers need to be aware of the macOS versions their projects target and make necessary adjustments.
Thus, while the difference between "arm64-darwin-23" and "arm64-darwin-22" is simply a version difference, it holds significant importance in software development. Proper handling ensures compatibility across different macOS versions.
