I loved, and lived by, iCalViewer. It still 'runs' in 10.8.5, but it doesn't see any of my Apple calendars, it only sees my Google calendar which is blank anyway. Sadly that is still better than what TimeWorks does, which is nothing. Unless crashing counts as something. TW doesn't stay running long enough to even see the UI, that's assuming it has a UI because I wouldn't know. As is I wouldn't keep it on my Mac if it were free, which it isn't. DateLine seems to be the next best thing but I miss iCalViewer's "finish line" approach to showing appointments, meetings, etc…
