I bought a new keyboard recently: the Lofree Flow 2 with 84 keys (so a 75% layout) in ISO-DE, with keycaps intended for macOS.
At first glance, that sounds like exactly the right combination for me. Compact, mechanical, pleasant to type on, visually clean, and supposedly Mac-friendly. In practice, however, I ran into a surprisingly annoying problem almost immediately.
On the Q key, the keycap shows the @ symbol. That is already slightly misleading, because on this keyboard, that does not behave the way my muscle memory expects on macOS. Under Windows, this sort of placement often makes sense because Alt+Q can produce @. But on macOS, if your fingers are trained differently, things become awkward fast. Even worse: a wrong combination in that area can easily drift into Cmd+Q, which closes the currently active application. That is irritating, but still survivable.
The real issue sits elsewhere.
