For MacOS Catalina

  1. download the latest version https://www.xquartz.org
  2. install it as the instructions
  3. restart your Mac (this step can solve "cannot open display")
  4. open the terminal application in XQuartz and input xterm to test

For Linux

Once you restart your Mac, you can directly login your remote host
ssh -Y yourUserName@host
test xterm, it will open a new window on your Mac.

DO NOT export DISPLAY=IP address in your .bashrcfile

Using the steps above, I succeeded in solving problem like 'Gtk-WARNING **: cannot open display:'

Hope these tips will help someone in the same trouble like me.

Good luck!

Instead of using -Y you should use -X
You will need to add the following to .ssh/config on the mac side:

Host *
	XAuthLocation /opt/X11/bin/xauth

this is because xauth lives in a different location on macos than it normally would on linux
