Scroll Reverser. Not as often now, but back when my MBP was my “everything” computer, I’d use a mouse and separate keyboard regularly.

But if you ever use a mouse regularly, you’ll notice that the scrolling follows the natural scroll direction of the trackpad. Scroll Reverse lets you invert it just for mice.

Also Macs Fan Control. Not really an issue on the new M-chips, but for anyone with an Intel Mac reading this, this is a godsend. Set your own fan curve, and monitor CPU temps from the nav bar.
