Activity Monitor - How to view multiple panels at the same time I'm currently trying to view multiple metrics at the same time using Activity Monitor app (yes I have tried top, htop, etc but I was wondering if this is possible with Activity Monitor). 
Fx. looking at the CPU and Memory panels without having to switch between them.

Thanks guys!
You can choose your own set of columns to be displayed on any particular tab by right-clicking on the column headers (or View → Columns) and checking columns to be displayed. For example, this lets you show the Memory column while on the GPU tab.

If you really want to display two different tabs using two windows, you can launch a second instance of Activity Monitor with open -na "Activity Monitor".
