AppWrangler
Keep every app on your Mac in check — CPU, efficiency cores and memory, per app. A free, open-source menu bar app for Apple Silicon Macs.
Helps the app you're using stay fast, even on an 8 GB Mac with lots of apps open.
- 🪄 Works on its own. Auto mode keeps the app in front at full speed and moves everything in the background to the efficiency cores. No rules needed.
- 🧊 Rescues low-memory Macs. When memory runs short, it can freeze the apps you haven't touched for a while, and each one wakes the moment you click it. It also tells you which app is eating your RAM and what to do about it.
- 🎛 Puts you in charge when you want it. Per-app CPU limits, efficiency cores and memory limits, with conditions such as "only on battery". You can also ask Claude to tune your Mac for you.
Free and open source (GPL-2.0), for macOS 13+ on Apple Silicon. It uses well under 1% of one core and never connects to the network.
