Not true.

MacOS releases a new version each year, the current MacOS landscape looks like:

- MacOS Sequoia (previous version, everything works as expected)

- MacOS Tahoe (current version, broken experience, basically Apple's "Windows Vista/8 moment")

- MacOS Golden Gate (next version, fixes what was broken in Tahoe, comes out in a month)

I'm on MacOS Sequoia because I have things that can't be broken by updating to Tahoe.

I also cannot test how my websites/webapps will work in a month, because Safari's beta (called Safari Technology Preview) only works on Tahoe and Golden Gate.

I cannot wait a month to update to Golden Gate because Golden Gate drops support for my iMac.

And I can't test the new version of Safari on my Windows or Linux devices because Safari isn't available for them.

I can test the Webkit browser, but that doesn't include the Safari specific changes that apple makes which I need to be able to test.

So, I can't test Safari until I wait a month and purchase a new apple machine.

(Oh by the way, apple keeps cancelling orders for new machines)
