By default, it shows path: /etc/fppkg.cfg
When I tried to change path in a combobox to /Users/mac/.config/fppkg.cfg
I immediately got Access violation error in Lazarus and it aborts.
I tried to recreate this configuration - the same Access violation error.
I checked this file - /Users/mac/.config/fppkg.cfg
It exists and seems to be OK on first glance.
Note, that I have a clear new macOS installation, with no old versions of Lazarus or FPC.
