Yes. Every MacOS update is a shitshow of things that stop working. My company always have to send out a message to everyone asking them not to update when a new OS version is out, until it's been tested some more. Always break something.
We do this in IT for windows. A mac update is exactly like a win10 version update, and both require testing before rolling out. We spend months testing Windows10 version updates. You just don't see it because its all behind the scenes. Right now we're committed to ONE win10 upgrade a year due to this.
That sounds like a security nightmare. How do you handle out of bound security patches?
He probably meant feature updates, security updates was at-least for us, 2-3 days of testing.
Separating feature updates from security updates was one of the best things Microsoft ever did.
True, but it was nearly a "have to" for a rolling release used in big enterprise.
