How to reinstall macOS - Apple SupportGoodOperator wrote:
At first- I was experiencing frequent magic keyboard input lag, erroneous inputs, and constant disconnects/reconnects (which persists).
Someone suggested booting into safe mode and then booting back into regular startup, which I attempted. What has followed is a new issue wherein my 2.4Ghz connected mouse will jump over certain on-screen items, like links, or anything clickable.
The skips and jumps don't always happen but they happen 75% of the time or more.
I've tried everything I could find online short of reinstalling macOS.
I also have had an issue where the Macbook would wake immediately after sleeping, which I thought might be related to bluetooth, since something during my debugging of that pointed to that being the case.
I've started simply useing the pmset sleep now command since that is the only way I can have a functional sleep state on this $6000 computer. Needless to say I'm extremely disappointed.
Any help from the community would be great. Thanks.
Reinstall the macOS on top of your existing macOS is painless and certainly would be telling one way or the other.

It is unclear when you say " magic keyboard input lag" ...
are you saying the built in internal keyboard or an external keyboard?
if the mac is not performing as expect new out of the box, return it or exchange it for one that works.
