Apparantly, the manual is "incomplete" for OSX.
- Krita on OSX is randomly different than windows and linux. https://forum.kde.org/viewtopic.php?f=137&t=133233
- Filepaths are different too, this is the only predicatable difference.
- I have no OSX device.
Therefore, I cannot write these differences in the manual, nor can I anticipate them. This means that this cannot be solved with "sure, just tell me what to check", as I am not able to tell what is different.
For filepaths I can try to make a macro, so that this just copy-pastes the same lines everywhere, but for the rest it needs to someone who dedicatedly tests every single damn thing and crossreferences them against the manual and then fixes the manual.
