Hi,
Yes, Monkey Island 2 for Macintosh works here, but I had to use a Leopard Mac to extract the .img contents, and then Mac OS 9.2 to extract the archives themselves with StuffIt Expander. Modern versions of macOS won't extract the old HFS .img files anymore, but you can use the ScummVM companion (https://www.scummvm.org/dumper-companion) on a modern PC if you want to extract the .img files.
(I'm sure other extractors exist for modern systems, but since I have some old Macs here I just did it this way for the moment.)
I might write a small guide about this if people need it, because indeed Limited Run Games just put raw floppy images with zero instructions.
By the way, some of you may have noticed that the Limited Run Games version of MONKEY1-EGA has a corrupted DISK4.img file, which means that the game will crash when reaching the Mêlée Island map.
Fortunately, they also provided KryoDump images, so there's a way to recover a functional MONKEY1-EGA. Here's my guide for this:
