>The Big Sur 11.2.2 update is a good example of what’s almost a null change, yet requires ... 3.1 GB for an M1 model.

What Is the change?!

Official site doesn't have entry for 11.2.2 or am I missing something ?

GUI says this: macOS Big Sur 11.2.2 prevents MacBook Pro (2019 or later) and MacBook Air (2020 or later) models from incurring damage when they are connected to certain third-party, non-compliant powered USB-C hubs and docks.

Then for more details it sends here: https://support.apple.com/en-gb/HT211896

What about massive writings to SSD? has it been addressed? Or it's not a problem?

PS: GUI says for my M1 it's 2.17GB and article says 3.1 GB who is correct?



I get the feeling Apple isn't going to fix the swap issue anytime soon. I don't think they're being insidious about it, though: the BSD memory model is (arguably overly) complicated, and refactoring any portion of it's memory management is guaranteed to be a pain in the ass. The TL:DR is that MacOS doesn't virtualize memory, and when that memory is unified it will frequently spill over into the swap storage. I have no idea how Apple can pull themselves out of this one, and I have a sneaking suspicion that the swap usage will only increase as time goes on.


What do you mean that macOS doesn't virtualize memory? Would you mind expanding on your thoughts a bit more?


macOS doesn't use the BSD VM (UVM), it uses a heavily modified Mach VM.


Bug fixes and performance improvements, probably.

(The actual answer is that the release notes are only available in the US version of the support page: https://support.apple.com/en-us/HT211896 )


For some reason the en-gb page is missing 11.2.2, but it's on the en-us page:
