objc: Class RunLoopModeTracker is implemented in both /opt/miniconda3/lib/libQt5Core.5.9.7.dylib (0x168cffa80) and /Users/lewis/.julia/artifacts/d594d9e68b9d104aaf1a41d933728d2dad54c869/lib/QtCore.framework/Versions/5/QtCore (0x176e5aaa8). One of the two will be used. Which one is undefined.
Seems hard to avoid. The Python implementation will have QT5 and associated libraries for matplotlib. Not clear why Julia also needs its own QT. Possibly for other charting libraries not using Python?
