Here is the compatibility information.

It says for PT 10.3.10 (last PT10 version) your operating system needs to be 10.6.7 - 10.8.5
It also says for PT 2019.12 your operating system needs to be 10.13.6 - current

Cannot get both.

If you want PT10 to coexist with a 64-bit PT version, your maximum operating system is 10.8.5 which means the choice of PT version would be 11.0 - 12.4

To be compatible, that is. Anything else and you are experiencing on your own.
What we do in life, echoes in eternity.
