One of my biggest whims with mac is that you can't really snap windows... especially not with keyboard shortcuts. Download Rectangle or Magnet (very similar if not the same apps, Rectangle seems to be less resource "intensive").

I know a lot of devs use Fishshell already, but highly, highly recommend. If you're using VS Code I'd checkout Tabnine. Uses a fuck ton of ram but is very useful during longer sprints. I'd even go as far as to ask your manager if that could be a potential integration.

I've also assigned a handful of shortcuts and macros to my Logitech g502.

There's also some software out there that lets you use to different computers almost symbiotically. With my linux VM I can remote into it using NoMachine. You can transfer files, copy/paste, and more.

Please put the subwoofer on the floor, it makes quite the difference!

I've had this problem too... and man does it suck. What really helped me was getting out in nature. And this is coming from someone who would rather sit at my desk all day lol
