In searching for the solution the only one was shown in the screenshot below, which is not available in Mac version. Yes, I can scroll looking for the yellow/error triangle, but doing so through one tracker's 1500+ torrents is a major PITA. In uTorrent type clients I can sort on the 'Tracker' column and all with errors will be together.
Alternatively give us an 'Error' button in the Filters bar.
