I’m doubtful that the first card was actually ruined by formatting it in a Mac. My guess is that it was formatted into a "file system" the Sony can’t recognize, probably either the APFS or HFS+ file systems which are used by Macs of various generations.
And I’d feel fairly certain that the reasons Sony says to only format the card in the player are to allow it to establish the appropriate file system on the card, and to allow it to create a set of named folders that it is designed to work with when it is being used.
I’m also guessing that the Sony utilizes one of the many variants of the Linux operating system, and formats the card into an Ext4 file system.
What I suggest that you do first is to try to re-format the apparently failed card in your Mac, choosing a file system that is recognizable by essentially all modern computer operating systems, such as FAT32. Then see if the Sony can recognize the card and re-format it into its own format.
As far as being able to transfer files with the Mac on a card that has been formatted by the Sony, if I am correct in presuming that the Sony uses Linux and the Ext4 (or earlier Ext) file system I believe you would have to purchase and install the following program in your Mac:
