No official package manager.
The Macbook cases ground through the user when they're on an insulated surface (there is no ground pin on the Macbook power adapters).
Audio crackles when the machine grounds through the user. Makes speakers hum.
I guess some of these are hardware issues.
The ground connection, where available, occurs through the metal stud which the duckhead slides into. Correct me if I'm wrong, but even the UK (Type G) duckhead doesn't connect ground even though the physical ground pin is mandatory.
I know that most DC adapters are unearthed, but my lived experience is that you can often feel electrovibration in the aluminium Macbook chassis when ungrounded and it goes away when the Apple DC adapter is grounded.

The first time I noticed it I was a bit worried about it all. I had a volt stick from work (a safety device to identify live wiring) and surprisingly it illuminated when I brought it near the metal chassis of my macbook. Some further tests with an oscilloscope showed that it was floating a good couple of hundred volts, but the capacitance was so low that the energy payload was never going to do any harm to a human. I don't care, I still just ground the thing.
As for specific features, I'd really like to see a list of all the different MacOS components so I can remove the things I don't care about (iMessages, Photos, Facetime, etc.) like I can do on all my Linux boxes. It would be nice to have integration with MacOS' various distribution formats too, and while we're asking I'd love to see a declarative approach like NixOS, that would really put MacOS head-and-shoulders above your average Linux distro.
Every other OS, be it windows, android, ios, linux, *bsd,... has a package manager included. Mac is the only hold out.
That's a watchdog kernel panic (maybe). Shouldn't be seeing that unless you have misbehaving NFS mounts or something.
Usually, I was able to get it to complete whatever it was trying to do and log me in by holding it directly in front of my air conditioning unit (this was as ridiculous as it sounds), but a few weeks ago even that didn’t work. I had to completely wipe the machine and reinstall macOS. It’s been fine so far.
Logic board was replaced "under warranty" (it's a 3 year old machine with no Apple Care!).
Oooh, I had fun with this one on an airplane. Kept getting shocks to my funny bone.
That's the app store. It just needs to be extended to deliver a wider range of things like CLIs or system extensions.
