LOL, I actually just checked right after commenting, I was commenting too early!
Happy to tell that it now works perfectly and I can view my file normally.
I used the version given in the link,
ST-klayout-0.26.9-macOS-Catalina-1-qt5Brew-RsysPsys.d…
Thanks for the replies, sorry that I was unable to do more tests without the knowledge of how to compile it from source. I am totally new to Mac and still trying to figure out how to run some other software lol
@ sekigawa, thanks and great to know!…
