Hello Techuser99,
I understand you are trying to share your MacBook Pro screen to your iMac, and wish the MacBook displayed full screen. I am happy to assist! Here is an a guide that discusses how to do this:
Share the screen of another Mac
This article contains the section "Screen Sharing Preferences" with the following information:
- On your Mac, start a screen sharing session with another Mac on your network.
- Choose Screen Sharing > Preferences, then set the following options:
- Under Display, select “Scale to fit available space” or “Show full size,” depending on how large your screen is and how much of it you want to use for the shared screen. This option changes the default behavior for when you share the screens of computers you’ve never connected to before. To change the current scale, choose View > Turn Scaling Off or View > Turn Scaling On.
If you have any issues let us know!
Thanks
