MacIosInfo
Resolve a macOS build number (the value Xcode writes into BuildMachineOSBuild,
e.g. 24G830) into a macOS version and marketing name.
MacIosInfo.macos_build_to_macos_version(build_number: "24G830") #=> "15.7.9"
MacIosInfo.macos_build_to_os_name(build_number: "24G830") #=> "macOS Sequoia"
MacIosInfo.macos_version_to_os_name(version: "15.7.9") #=> "macOS Sequoia"
Installation
Add this line to your application's Gemfile:
gem 'mac_ios_info'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install mac_ios_info
Usage
macos_build_to_macos_version
Returns the exact macOS version for a known build number.
MacIosInfo.macos_build_to_macos_version(build_number: "20D80") #=> "11.2.2"
MacIosInfo.macos_build_to_macos_version(build_number: "24C101") #=> "15.2"
MacIosInfo.macos_build_to_macos_version(build_number: "25G83") #=> "26.6.2"
A build number begins with the Darwin (kernel) major version, so when a build is not in the table the major version is still derived from it rather than giving up:
# a point release published after this gem was updated
MacIosInfo.macos_build_to_macos_version(build_number: "25Z999") #=> "26"
"UnKnown" is only returned when even the release family cannot be determined:
MacIosInfo.macos_build_to_macos_version(build_number: "99A1") #=> "UnKnown"
macos_build_to_os_name
Goes straight from a build number to the marketing name. This works for every build of a known release family, including ones not in the version table.
MacIosInfo.macos_build_to_os_name(build_number: "24A335") #=> "macOS Sequoia"
MacIosInfo.macos_build_to_os_name(build_number: "24Z999") #=> "macOS Sequoia"
macos_version_to_os_name
MacIosInfo.macos_version_to_os_name(version: "10.13.5") #=> "macOS High Sierra"
MacIosInfo.macos_version_to_os_name(version: "11.2.2") #=> "macOS Big Sur"
MacIosInfo.macos_version_to_os_name(version: "26.6.2") #=> "macOS Tahoe"
MacIosInfo.macos_version_to_os_name(version: "15") #=> "macOS Sequoia"
Supported releases
| Darwin | macOS | Name |
|---|---|---|
| 16 | 10.12 | macOS Sierra |
| 17 | 10.13 | macOS High Sierra |
| 18 | 10.14 | macOS Mojave |
| 19 | 10.15 | macOS Catalina |
| 20 | 11 | macOS Big Sur |
| 21 | 12 | macOS Monterey |

| 23 | 14 | macOS Sonoma |
| 24 | 15 | macOS Sequoia |
| 25 | 26 | macOS Tahoe |
Exact build numbers are listed for macOS High Sierra through macOS Tahoe. Builds outside that table resolve to the release family via the Darwin major version, so a new macOS release does not have to be added here before it reports correctly.
Development
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
