I have some further observations.

Firstly, I installed LibraCAD on my son's old Mac Mini which is running High Siera. On that system the parallel function works.

I then compared Version 2.1.3 with Version 2.2. rc2 of LibreCAD on my own MacBook Air running Big Sur. I get the same strange behaviour with both versions of LibreCAD. However, I noticed something else. Whereas on the Mac Mini, when I select the Parallel function and move the cursor across a line I get parallel lines appearing on ether side of the original line depending on the side from which I approach the original line. I believe that this is the correct behaviour. However, on my MacBook Air as well as only having parallel lines appear when the original line is either horizontal or vertical, the parallel lines will only appear on one side of the original line.

Unfortunately, I have no way of determining whether this behaviour is related to the hardware or to the operating system. The Mac Mini is quite old and High Siera is the last version on the Mac OS which is compatible with it and downgrading the MacBook Air to High Siera would be an horrendous challenge.
