Fixing 7zip High RAM Usage on Mac
## Direct Answer
To fix 7zip using too much RAM on your Mac, you can try limiting the number of CPU cores it uses. You can do this by opening the Terminal app, navigating to the 7zip installation directory, and running the command `./7z -mmt=1` to set the number of CPU cores to 1. Alternatively, you can also try updating 7zip to the latest version or disabling multicore support.
## Step-by-Step Guide
Here’s a step-by-step guide to fixing 7zip high RAM usage on Mac:
1. **Open Terminal**: You can find Terminal in the Applications/Utilities folder, or use Spotlight to search for it.
