The MacBook software is so good that I’ve never had issues with misclicks or movement despite your palms sitting on it while typing.
Long ago I installed Linux on a MacBook and found it unusable because of clicks and movement while typing. It’s probably improved these days though.
It is so incredibly "weird" to press on a MacBook (non Neo) trackpad when it is off, it's like touching a dead thing.
I had palm rejection work perfectly in my 2015 laptop; for my 2022 laptop, I had to switch to Fedora for the latest software.
