Greg Hurrell 32d084e9ed fix(homebrew): wrap macOS version dependency in on_macos block (#1264)
GoReleaser's Homebrew template always emits a bare `depends_on :macos`
for macOS-only formulae. Combining that with the `depends_on :macos =>
:ventura` line injected via custom_block triggers a Homebrew deprecation
warning on `brew upgrade`:

  Warning: Calling `depends_on :macos` with `depends_on macos:` is deprecated! Use `depends_on :macos` with `depends_on macos:` inside an `on_macos` block instead.
  Please report this issue to the cirruslabs/homebrew-cli tap (not Homebrew/* repositories), or even better, submit a PR to fix it:
    /opt/homebrew/Library/Taps/cirruslabs/homebrew-cli/tart.rb:22

Declaring the version constraint inside an `on_macos` block is the form
Homebrew recommends and silences the warning without changing behavior
(still macOS-only, Ventura or newer).

Tart is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon. Built by CI engineers for your automation needs. Here are some highlights of Tart:

  • Tart uses Apple's own Virtualization.Framework for near-native performance.
  • Push/Pull virtual machines from any OCI-compatible container registry.
  • Use Tart Packer Plugin to automate VM creation.
  • Easily integrates with any CI system.

Many companies are using Tart in their internal setups. Here are just a few of them:

Note: If your company or project is using Tart please consider sharing with the community.

Usage

Try running a Tart VM on your Apple Silicon device running macOS 13.0 (Ventura) or later (will download a 25 GB image):

brew install cirruslabs/cli/tart
tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest tahoe-base
tart run tahoe-base
