I guess, you should just try running KRE on your M1 mac. It should run.

Why I guess so? See the following post by @duyluong of Katalon

I guess that Katalon Runtime Engine is built as a x86-64-based application software. On mac with Apple silicon chip, KRE run on top of a emulation layer named [Rosseta 2](https://en.wikipedia.org/wiki/Rosetta_(software)). The Rosseta 2 provides an X86-inteface to the application. The x86-64 to Arm64 instruction translation makes the application run slow.

So KRE should run on Apple M1. However you should note that it could be **slower** than Katalon Studio for Arm64. Here is a performance comparison report: [Katalon is slow to execute tests cases on MAC - #31 by kazurayam](http://forum.katalon.com/t/katalon-is-slow-to-execute-tests-cases-on-mac/99924/31)
