Bushel - the macOS virtual machine app for developers
I'm looking for beta testers!

For developers who want to be rigorous and uncompromising in their app testing.
You can set up your virtual machine for almost any configuration, from a fresh, factory reset of the Ventura beta all the way back to Big Sur.
Test, simulate, roll back and debug apps and scripts however you need to without worrying about destroying your machine.

If you want to be invited to our first TestFlight, or even if you just want updates on Bushel, sign up at the website, and we will get in touch with you.
