Welcome to the list, hanNd2NO.
Before getting into the details, what version of AutoKey are you using?
If it's not 0.95.x, then you should upgrade, if possible, for many reasons.
(I'll provide instructions if that's the case.)
My experience is that you can copy anything into the proper directories
and they just work - if the files are good.
However, they do not show up in the AutoKey Main Menu (if it is open)
unless the menu is closed and reopened.
So, try closing and reopening the Menu after adding your abbreviation files.
If that doesn't work, try closing and restarting AutoKey (making sure
it's gone with something like ps -ef | grep [a]utokey.)
If that still doesn't work, try both steps again, but with an AutoKey
trace running. It probably won't show us anything, but it's worth a try.
In any case, whenever you're trying something new like this, you should
be running AutoKey from a terminal so that you can see any error or
warning messages it issues.
See
https://github.com/autokey/autokey-python2/wiki/Problem-Reporting-Guide
for how to run a trace.
If you post any trace output to this list, etc., please review it first
to assure that there's no sensitive information such as passwords in it.
I am attaching the .txt and .json files from one of my working phrases.
It has a hotkey and a trigger phrase defined.
You can compare them with your generated phrases.
You can also install them on your system to test your installation
procedure.
Just to make sure, what does OS X use for a newline? Is it the same as
Linux - just a linefeed, or a carriage return+linefeed like Windows uses?
Something invisible like that in your files might cause an issue.
If this doesn't either solve it or give us actionable clues, then we'll
have to pursue it with the developers.
(So, save any test results, etc. in case we have to show them to the
developers.)
You could also post one of your phrases (both files as attachments), I
can see what happens when I try to install them here.
When you do get it to work, it would be great if you could share it with us.
