I have written a Wiki page with snapshots for this issue. Feel free to edit 
and/or reformat as needed. Once a 25.2.2 RC is released, I can just add a new 
Step 1 that says “install LibreOffice 25.2.2 RC or later”:

https://wiki.documentfoundation.org/MacOS/Dark_Mode

I want to thank Cloph for the Light Application Color extension workaround. I 
also want to thank Sahil for jumping in and handling all of the theming code 
and creating the extension that give users a way to get their document content 
in light mode.

Essentially, the unexpected change in recent macOS updates (they surprisingly 
removed a deprecated features in a minor release) is the trigger for this 
issue. Users wanting the old look (document content in light mode and toolbars, 
etc. in dark mode) find their way to the Appearance preferences and change that 
from “System” to “Light”. With the Apple change, the system colers don’t change 
(they now always return the color for the system light/dark mode, not the 
applications light/dark mode leading to both light and dark colors mixed 
randomly into an unreadable mess even when you switch back to “System”.

I will try to get links to this Wiki page on r/libreoffice and in bugzilla. 
Keeping LibreOffice on the 24.8 branch for now I think will really reduce the 
support load. Hopefully I can find a fix for bug 156855. Documents appear to be 
using cached colors and some colors won’t update the color until LibreOffice is 
restarted.

One last thing: I am expecting that we will see a steady stream of “cannot see 
any black text in document” posts (i.e. the first “known issue” in my Wiki 
page). My prediction is that this will be the biggest cause of users changing 
the appearance from “System” to “Light” and might affect all platforms.

I don’t know if this is still the case, but back when I added full dark mode in 
NeoOffice, there were a lot of users that had documents with all the text set 
to black instead of automatic. Maybe Microsoft Office or Apple’s Pages and 
Nmbers? I don’t think this is our bug but we might need some help from 
marketing to get the word out on what to do when this happens.
