One of the inconveniences of using MAC OS is, without a doubt, Korean input.
Of course, it may feel like the problem is resolved once you get used to it.. However, for some reason, I seem to be making a lot of typos when working on a Mac lately, so I looked it up and found that Gureum Inputter, which is widely used in the Mac environment, has started supporting Apple Silicon Macs.
Since the usage instructions are clearly shown on the site, I recommend checking them out and giving the installation a try.
It seems the most outstanding feature of Gureum Inputter for first-time users is the ability to input Korean using the Command key on the right, mimicking the Windows environment. Of course, I’ve gotten used to switching between Hangul and English using the Caps Lock key on the left, but... after all, the Windows shortcuts I’ve used for a long time seem better.
(Because it's hard to change Caps Lock to Hangul/English switching on Windows...)
I hope this helps those of you who are struggling with key input in a Mac environment, just like me.
