I have a finder extension and have noticed that when I switched the finder display mode to 'cover flow' that a second instance of the FIFinderSync is allocated and then after that calling:
[[FIFinderSyncController defaultController] setBadgeIdentifier:overlayID forURL:url];
fails to set the badges anymore. I noticed that Dropbox has the same problem.
Should I be using something other than [FIFinderSyncController defaultController] or is this a bug in the finder?
I am running 10.13.5.
