The System Watcher allows you to monitor the status of your system. Processor, memory, network, gpu and disk based information is displayed.

The System Watcher is a lightweight yet powerful app to monitor your system.

• Basic System Information
Keep track of all your system loads. This includes CPU load, memory usage and network speeds.

• Menu Bar Extra
The menu bar extra shows the network download- and upload speed, the total CPU usage the used memory. Additional menu bar widgets can be unlocked with System Watcher Pro.

• Overlay Window
The overlay window always stays on top of other windows. So even if you have a full screen app running, you can use the overlay window to keep track of your system.

• Battery Information
You can check the battery parameters on the battery page. This page shows detailed information about the internal battery. If you are using a Mac without battery, this page is hidden.

• GPU page
See information about the state of your primary graphics card.

• Disks page
See all connected disks and their current performance statistics.

Great little app!

This is what I was looking for and an improvement for certain things over what you get from Activity Monitor.

It seems to work well and uses very little resources. I'll watch for a bit and will probably end up getting the full version.

I'll be buying the full version soon. Going to test it out a bit longer, but I'm pretty sure.

Developer Response ,

Thank your very much for your kind review. A big update for the System Toolkit is planned for macOS Big Sur 👍
