Oh yeah, and you don't have to be afraid an OS update will make your laptop unbootable. Has happened to me under Ubuntu twice.
That's not true. Apple's yearly OS upgrades can and do brick machines. At least with Ubuntu, I'd stand a good chance of diagnosing and fixing the issue.
Also, we are just talking about Ubuntu here and not all Linux distributions. For example, NixOS is a Linux with an entirely different method of managing upgrades.
- Apple Kerberos does not support MS-KKDCP and multiple factor auth. Services that require Authentication Indicator are simply not available from macOS. Their Ticket Viewer is even more simplistic than in 10.6 timeframe.
- Their IPSec implementation is weird and haven't managed to make it work with Strongswan yet.

Just wait, sometimes it happens there too. There's a reason for that recovery partition.
