The macOS Monterey beta is available right now to anyone enrolled in Apple’s developer program or the company’s Beta Software Program.

The macOS Monterey beta requires a large download for all compatible Mac models. It’s several gigabytes which means it will take awhile for the download and installation to finish up.

We can’t tell you exactly how long the installation process will take because mileage will vary from person-to-person and device-to-device. The timing also depends on your familiarity with the beta process and your current version of macOS.

That being said, we can help you approximate how much time you’ll need to spend downloading and installing the macOS Monterey beta on your Mac.
