Unfortunately, Apple changed their console log system a few years back, and it’s much less easy to use for the average person. You could try the following, but I’m not 100% sure that it will work.
- Open the Console app.
- Type uchr in the search field at top right.
- Click the start button.
- Now move the keyboard layout into the Keyboard Layouts folder.
- Hopefully you will see if there is a problem.
Sadly, when I try it, it doesn’t seem to work. There may be some way around this, but I haven’t been able to find it in limited testing.
The only guaranteed method I know of is to use the command line program klcompiler to check it. The problem there is that this has to be downloaded from the Apple Developer site, which requires an Apple Developer account. That’s free if you want that, but it’s more hassle than most people want to go through. If you do want it, it’s part of the Font Tools package.
