How do you keep edit selections and adjustments when transferring raw files?

I'm editing raw shoots in Lightroom Classic on my macbook pro laptop in the field, making selections and making ajustments on those selects.  So from a shoot of say 1,000 images I will select perhaps 200 4 star on a first pass and of these images I may select 50 to be 5 star on a second pass. I'll spend some time making adjustments on the 50 5star final selects. 

When I return to base I back up the whole raw shoot to my data storage and then import these raw images into Lightroom Classic on my iMac Pro desktop so that I can see the images better on the larger screen and refine the edit further.  

I would like to be able to import all of the selection and adjustment data that I made on my laptop when I open the images on the desktop but I've not found a way to do this.  I've tried saving metadata to the raw files (command S) on the laptop before copying them to my data storage but this metadata info isn't recognised by the desktop LRC.  I'm running 10.15.7 on the desktop 10.14.7 on the laptop and LRC 10.3 on both machines.  Any ideas on how to fix this would be much appreciated.
