I am (mostly) a Mac person. I have my work laptop and a personal MacBook Air, and the 2019 vintage Mac mini that I am currently typing on. Work is rather militant about keeping the OS up to date for security purposes. Usually, when Apple releases a new MacOS version, the brains at our Infosec group usually spends about 3 weeks to validate that all our internal apps function.
This time was different. They did all that validation before launch date, and they announced on the eve of the launch that we were ready on Day one, even going further and *STRONG* recommending that we all upgrade ASAP.
I am a good doobie, so during lunch, I turned around and did the upgrade on my Mini that is pinch-hitting until my PC components arrive later this week, and the upgrade went smooth. Including the download of 4.5G of data, it took about 25 minutes to upgrade.
Thus after my last call ended at 4:00PM, I fired up the upgrade. About 5:30 I returned to the computer and logged in, checking a few of the usual suspects, and all is well.
Before I retired, I kicked off the upgrade on my MacBook Air. All three updated on launch date.
Love or hate Apple, they do make major updates painless.
Glad it was an easy transition for you.
I have very limited experience with Apple, and it wasn't positive. Unless Linux emulators have gotten better about playing nicely with .docx, I'm stuck in M$ hell.
