"I need to test on Ventura but I'm on Sequoia"
Spin up any macOS version without touching your main system. Test backwards compatibility without the risk.
"I want to test Sequoia beta without nuking my laptop"
Kick the tires on new releases in complete isolation. Break things without consequences.
"I need a sandbox for crypto/sketchy stuff"
What happens in the VM stays in the VM. Delete with one click. Perfect for security research.

"I need to test against older Xcode versions"
Keep multiple Xcode versions in separate VMs. Test against any iOS SDK without cluttering your main machine.
