I upgraded to Mountain Lion, and then to Mavericks within days of their releases.
I was really disappointed with Calendar "Alert/Snooze" notification capabilities lost when iCal went away with ML (What were Apple thinking; appears an intentional exclusion to me.). So I was forced to purchase BusyCal from the App Store (It wasn't inexpensive). I discussed with Apple tech support, by phone (haven't done so about Mavericks yet) in the past, and spent too much time trying to get the person on the other end of the line to understand my issues - very frustrating. They couldn't understand what I was talking about (Don't Applers use calendars and snoozes - how do they keep track of their days schedules?). But BusyCal mimicked the snooze capabilities of iCal (and "MicroSoft Outlook" I was forced to use at my employer before I retired). And, although unhappy with having to pay $$ for BusyCal, I've been doing fine since.
Then, after I upgraded to Mavericks, I read the original post to this string and was getting happy - until I tried Mavericks snooze (I didn't drop my BusyCal app - never get rid of what works until you have a viable alternative). For the life of me, I can't figure out why Apple (by the way I am a GIANT Apple fan; have been for over 30 years - own almost 1,200 shares of AAPL common stock). And I understand new software releases are likely to have bugs/issues. But this has been and issue, at least with me, for over two years (upgrades) now. I think that is way too long, unless there is something I don't understand here.
NOW TO THE POINT - Mavericks calendar "Snooze" options currently look mostly great to me. Except, based on my use of Mavericks calendar so far, if you are not at sitting your compurter when the "original" or "snoozed" calendar alert pops up it will "dissapear"/ gone within XX minutes, without your "affirmative" election to "do something," like "Dismiss" or "Snooze to a Later Date and Time" .... If it "goes away" you have lost it - not good! I need to be able tell my software (not them to me) when to "delete/dismiss" my alert notifications - not let "dumb" software make the decision for me.
Why can't Apple just mimick BusyCal???
Am I missing something?
