Sonoma Calendar iPhone Calendar Synchronization Problems

Hi again... (seems that I am talking to myself here)

Here again what I have done with Calendar over the last few years, up to and including macOS 12, and what I want to continue doing with macOS 14 and on:

I DEFINITELY DON'T want to use Calendar via iCloud, simply because it is not neccessary with my setup and because my calendars are sensitive data that is nobody else's business but mine. Period.

I re-thought the whole calendar thing and came to the conclusion that I only need one instance on my MacBook Air, plus a searchable archive of passed years (which in my case goes back to 2008). Such a searchable archive can be created by printing the whole caledar in weeks view and saving as a PDF file, that can be searched with simple apps like the Preview app.

For my weekly backup archive of Calendar I so far used "File", "Export", "Calendar Archive", which worked fine up to and including macOS 12.x.

During the time trying to fix my problem with Calendar v.14 macOS 14 last week I used "File", "Export", "Calendar Archive", as usual. During that time I had to completely delete the calendar data for several times and play back the backup I created. Then I discovered, that those restored calendars don't yield any search results anymore. The archive files have the extension ".icbu". So apparently there is a bug in Calendar v.14 handling icbu-files. BTW, older icbu archives from macOS 12 and older don't have that problem.

Next thing I did was a different backup, "File", "Export", "Export", to backup each calendar separately, in my case 4 calendars, each having the standard ".ics" file extension instead of ".icbu".

After resetting Calendar (deleting everything in the "Users/username/Library/Calendars/" folder) and playing back my 4 separate ".ics" files, searching through the calendars worked again! BTW, there is no need for things like "reindexing" because calendar is based on a sqLite database engine, so searching is always a query to the underlying SQL-database.

So, there still is the problem of synching the Mac with the iPhone via USB-C cable, without getting the calendars corrupted or completely shredded. There is the question why do database entries like a hole day event (on Mac Cal) become a 2 days event on the iPhone Cal. This is a significant bug that needs to be corrected, asap.

... I can't believe that nobody at Apple has done something about these problems for such a long time. The complaints are numerous and documented.

But I am still talking to myself...

Hi again:

As I can see, there seems to be no-one having the same problem. A brief update:

Meanwhile I upgraded to macOS 14.6.1 on ma MacBook Air M1 and iOS 17.6.1 on my iPhone 15 Pro. The situation did not change. The synching problems are still the same. :-( :-( :-(

Will Apple ever do something about it?

And another problem... Since the upgrade to Sonoma I can't do any searches in the Mac Calendar! :-( :-( No results, although there should be results... What happened? Being able to search for Calendar events is crucial to me.
