Otherwise we start to periodically get RST's from GitHub, possibly because of too many connection opens, which has an effect of cancelling previously received bytes. These RST's can be observed in tcpdump/Wireshark or Console, emitted from the libusrtcp.dylib library, com.apple.network subsystem, for the Tart process: >tcp_input [C59.1.1.1:3] flags=[R] seq=1805021659, ack=0, win=0 state=CLOSED rcv_nxt=1805021659, snd_una=1752355607 You can also observe the "Received Bytes" in "Activity Monitor" for the Tart process while pulling ghcr.io/cirruslabs/macos-runner:sequoia, and this value will periodically decrease.
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.Frameworkfor 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.
Tart powers Cirrus Runners service — a drop-in replacement for the standard GitHub-hosted runners, offering 2-3 times better performance for a fraction of the price.
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.
