Does Zorin OS support TPM 1.2 when installing?
Take a look at this guide:
(Zorin 17.x is forked from ubuntu 22.04)
ZorinOS has no TPM-related hardware requirements. You can install it with older TPM chips or no TPM chip at all.
Just to confirm for you - I installed Zorin Pro 17.1 to my 15 year old PC with no TPM.
You are good to go!
