For some time I can’t change the font of FileMerge. Then he suddenly started using the Helvetica font (sans serif, variable width) for files that he does not recognize (for example, typescript source files). This can be temporarily changed in Monaco by changing the font to ... Helvetica. Yes, this is very strange.
But now it shows all the text white on white, and only the changed section is visible due to a different background, and I can not change it. I tried to find all the pref files and reinstalled Xcode, but the text remains white on white.
Does anyone know how to change this or where to change the (pref) file?
This may be a write permission issue, as I run it from an account other than admin.
Thanks.
