I have anNSTableView showing the contents of a directory. I watch for FSEvents, and each time I get an event I reload my table view. Unfortunately, the current selection then disappears. Is there a way to avoid that?

Well, you can save selection before calling reloadData and restore it after that.

NSInteger row = [self.tableView selectedRow];
[self.tableView reloadData];
[self.tableView selectRowIndexes:[NSIndexSet indexSetWithIndex:row] byExtendingSelection:NO];

This worked for me in some cases. But if you insert some items BEFORE the selected row, you should andjust your row variable by adding count of added items to it.
