Pincer

A small crab who wants your Mac restarted. Memory safe, of course.

One of the 2 you pick with Notchpals ($4.99 once, with Blip), or $0.99 later, after you buy Notchpals. Plus local tax, if any.

Add to Notchpals opens Pincer in the app's Browse window, to try in your notch.

All 8 of Pincer's faces. Each line comes with the face that fits it.

Plugged in. Good. My shell can stop rattling now.

Over a week without a restart. Memory gets cluttered. Restart soon.

Disk almost full. I live in a tiny shell and I keep it tidier than this.
