SCUMM: Add practice mode box for Mac Loom Unlike the PC version, the practice mode box appears to be hard-coded in the Mac version. The script that draws the box in the PC version just sets variables in the Mac version. This implementation is based on screenshots. To keep things a bit saner, I've split out the Mac-specific drawing to its own file.

SCUMM: Make Mac Loom practice box clickable It turns out that the practice box (which shows note names in practice mode) is a verb. The DOS version turns this verb on and off when needed, but Mac Loom only sets variable 50 and 54. I have no idea why there are two different variables, because variable 50 seems to be enough. Anyway, this simply turns the verb on and off, and adjusts its coordinates. It seems to work well enough.
