you can use the built in VNC (edit:) if your linux machine is up to date and configured correctly.

In the finder , Go > "Connect to server..." and enter vnc://linuxmachine.local

I tried this to connect to a rpi that was setup and got

The software on the remote computer appears to be incompatible with this version of Screen Sharing.

So YMMV

AND, if you have some systems that you access regularly, you can add them to the Favorite Servers list in the screen that pops up.

AND AND, if you want a bookmark on your desktop or wherever, once connected to the system, you can drag the name of the system you accessed to the Finder.

Thanks, I've never knew MacOS has built-in VNC client

I use Nomachine. the built in mac VNC doesn't allow you to use the windows button on a conected PC

im having a rough time trying to get it to work with no machine.

If you're looking the one compatible with raspberry pi, you probably have brew, so vnc-viewer is an option

brew install --cask vnc-viewer
it's compatible with pi's (4 at least) vnc settings, so simply connect via the ip address (get it with netstat) like 192.168.100.5, the home.local didn't work

or
brew install tiger-vnc

You might want to give MultiVNC for Mac a try. It supports Tight encoding and encryption, has some limited power user features like statistics and input macros and is open source. Disclaimer: made by me.

The MacOS Screen Sharing VNC method does NOT allow for copy / paste into non-mac machines.
