MATE is a gnome 2.0 derivative, so none of the solutions I've read that involve running a shell-extension such as "dash-to-dock" will work on MATE. MATE Tweaks has but one checkbox "Enable dock" under panel. How to make it pop up when I move mouse cursor to bottom of screen? Looks like its only two behaviors are: 1) hidden when an app is full-screen in foreground; and 2) displayed otherwise. I have used docks in other desktops (gnome 3) and the "popup" behavior is one I'd like to see in MATE, which I overall prefer to the gnome 3 and KDE approaches.

Install plank and the option to enable dock will be activated.
Open terminal and run
sudo apt install plank.Then open
mate-tweakand go to the panel section.Select Enable dock. And you will get a Mac OS like dock.
To customize plank, open terminal and run plank --preferences
