I have a "Late 2012" Mac mini and a new 16" MacBook Pro. Both are macOS 10.15.2 - Catalina. Both are set to DarkMode. Both have qbittorrent v 4.21.
qB on the MBP is dark. qB on the mini is light. qB preferences are all the same. I can't find what's going on. BTW, the dark qB looks and acts great.
Any ideas?
