Android Calendar Sync to Mac sans Google Calendar?

Hello all. I am new to this board and this is my 1st post. I am looking to upgrade my current phone to an Android device in September, and am highly leaning toward the HTC Incredible. I have a very important question, however, that I can't seem to find an answer to...

I have an Imac desktop computer, am still using a Palm TX device, and it's calendar, to dos and memos, are all very important to me. Ideally, obviously, I want my Android device to replace my Palm, however, I'm wondering if there is a way to sync the calendar on the Android phone, to my Mac computer WITHOUT using Google Calendar at all. I am very adamant about NOT using Google Calendar, as I do not want any type of internet based calendar. Can this be done? Does the android phone come with desktop calendar software for mac, or is there some type of sync software available on the web? Or can it be synced with my ical calendar (without involving Google Calendar)? Any and all help is greatly appreciated. Thanks!
