when screen sharing from old 13” retina MacBook Pro to old iMac - how can you have iMac go full screen ? (As opposed to exact size of retina MacBook ?)
to iMac screen how can scale to fit the iMac screen?
MacBook Pro 13″, macOS 12.1
Sure, using an external monitor will allow you to specify any resolution that monitor can support. Read Connect an external display to your iMac - Apple Support or Use an external display with your MacBook Pro - Apple Support.
Connect a display to your Mac - Apple Support discusses AirPlay also.
You don't.
Scaling is either on or off. A Mac whose screen resolution is lower than the one you are using to view it does not get enlarged merely to fill the screen with a bunch of enlarged pixels.
Thanks - figured that might be the case.
does it scale up if I use a normal monitor (not iMac) with HDMI?
