IMO, https://www.ifwiki.org/index.php/Glulx is a poor choice of link to help people who don’t know how to play a Glulx game. It starts with a list of versions, then it has a “How to play” section, which just links to https://www.ifwiki.org/index.php/FAQ#How_can_I_download_and_play_IF.3F which, in turn, suggests Gargoyle for all platforms (“Gargoyle works well on Windows, Linux, and Mac.”)
In 2021, I strongly disagree with Gargoyle as a recommended interpreter for macOS, because the latest 2019.1 version doesn’t support HiDPI displays (i.e. any MacBook sold since 2018); the result is a blurry mess on macOS.
On a page like this, rather than “Any Glulx/Z-code player”, I recommend suggesting your favorite interpreter.
My favorite desktop interpreter is Lectrote, which actually does work great on Windows, macOS, and Linux (unlike Gargoyle). My favorite Android interpreter is Fabularium, and my favorite iOS interpreter is Frotz.
