Never heard of it, I'll give it a try!

If you're talking about the program you use in the terminal, you can install it via homebrew

No, the GUI. 7-zip integrates well with the shell: select a group of files, right click -> make zip file, and so on. Or right-click a zip file and select extract. If you're accustomed to Linux you might not know what they're talking about.

TortoiseGit (and TortoiseSVN) are similarly convenient. Right click a folder with an SVN repo checked out, and select "SVN update". Right-click an empty space, and select "SVN checkout". SVN was the main distribution method for some modding communities before things like Steam Workshop and Github, specifically because TortoiseSVN made it so convenient. Checkout into your addons folder, and periodically update. What could be simpler?

How about PeaZip?

I've used PeaZip in the past but only on Windows, I was not aware that a MacOS version exists! I'll give it a try. Cheers

Imagine voluntarily moving to mac.
