Edit: and a follow-up question, is there a good Z-Machine interpreter for the macOS terminal?
Regardless of which you play, there are likely to be frustrating, unfair, perhaps unsolvable puzzles present. Modern players often have the Infocom invisiclues at hand while they do so.
There are some pretty nutty things buried in the game, though - there's a spot in Zork 1 where by typing "temple" or "treasure" at the appropriate location you can teleport from one to the other - the supposed hint for this is they both have a granite wall. WTF?
I believe at the time, as a teenager, I finished most of the Infocom games available without using clues - it can be done. I think I never got the optimum outcome for Deadline.
I recently (this year) finished Starcross without hints or clues, aside from the copy-protection "map" at the start.
