icloud doesn't sync all my devices

This problem has caused me profound problem after an apple tech advised that I completely wipe and restore my drive, I have spent days worth of hours trying to work it out with MacOS Sierra because of the following issues, and even lost thousands of dollars worth of business due to apple mail sync dependencies:

Everything is contact driven but my contacts across multiple devices are out of sync

A tech didn't realize that the profile and drive had been migrated, so there was a duality in the boot records so completion of my iCloud sync never completes and the permissions are all incorrect.

My Profiles go up but do not come back down - and the apple webpage does not let you access multiple folders - so doing this for about 10000 files and recreating the structure - on an external drive that apple indexes while your trying to do it is nearly impossible.

Engineers were not aware of the folder hidden in the iCloud that can be revealed through SUDO commands that contains the backend metadata for over 300 applications, and those applications on each device since 2006 AppStore launched and almost wiped the back end after I downloaded every file 1 by 1.

After multiple rebuilds I cannot get a 2015 MacBook Pro back to a Single User / Non - Networked in sync profile mode because of a stuck sync which keeps bringing down the settings even though I turn them off, or attempt too, in settings, prior, so I end up in a several day reset pattern.

Consequently - you can see the problems this would cause with something like XCODE or even MAIL when MAIL can't get your contact information right.

The key seems to lay in 3 specific arenas: after El Capitan your Macs extremely dependent on contact information - 1. for Siri which is a pain, but the least of my issues, as 2. when it is out of sync across several devices causes huge problems with mail and calendars. 3. The iCloud will not resume proper sync if you lose your original migratory UUID information with the previous boot record which I have, but don't know how to make the mac approve both as it did previously and the 300 or so folders of metadata that support iCloud based "shared apps" that I lose if engineering resets my iCloud account on the back end (think purchases made prior to iCloud, handoff or even Microsoft word)- I am Mac loyal since the age of 12 however being told "We do not guarantee retrieval of information from the iCloud" and several weeks (hour to hour) of support, I am at my wits end. I just want to be able get back to working on apps as easily as I can on a PC - without losing 10 years and thousands of dollars of data. Has anyone iCloud issues this to this degree? I have been in data science and development for 2 decades and there are so many undocumented aspects that I don't know how to fix this.

Any help would be appreciated more than you know.

I'm assuming you are no longer syncing with iTunes to get contacts, calendar, etc. synced between devices (but mail is a different matter, the mail app does the syncing). If your iphone and mac are connected to icloud and you have turned on calendar and contact syncing in System Preferences/Settings, then they will sync that data. You indicate that it seems to. However, that syncing process means the data is also stored in iCloud and you can view it (email also) by logging into icloud.com with a computer browser.

You imply that the contacts and events in calendars are not listed in icloud.com. The only way this can happen is if you are logging in using a different icloud ID than the one used on your devices. I suggest you look at the mac and iphone to verify what the ID is. It cannot be the same as the one you use to log into icloud.com with browser.

As for letting someone else access to your data on icloud (I assume by giving them your ID and password), this is like giving your PIN to a friend so they can log into your bank account via the web.

ALL I HAVE FIGURED THIS OUT! It took me around an hour, and this is for when the updates on your Mac calendar don't show up on your phone. You need to make sure that when creating the event on your Mac, the Calendar it is on is the iCloud calendar. Double click the event, hit edit, then click on the Caledar - a menu should pop up. Make sure to choose an iCloud calendar.

For myself, I have deselected all calendars that are only on my Mac and selected and created different calendars under the iCloud option. Seeing I use both and iPad, iPod Touch and my Mac I need all my calendar events accessible on all my devices along with the alerts sent via the cloud.

So if I have something that has an alert to remind me of an event and I am on my iPad I and not near the Mac I would not know.

So in my opinion if you have more than one device it would be in your best interest to have all calendars in iCloud and not any on your Mac but that choice is clearly yours.

But for me this is the system the works best for me.

iCal on my Mac sync to iCloud but not all of the calendar sync to my iPhone 4S and iPad 3rd gen. Older data lost but immediate data appear as soon as I update my iCal on Mac. Older data means that after a week or two the data gone from both iPhone and iPad, but still there on Mac and iCloud. What should I do? Anyone please advise!

Put all calendars, on all devices, in the iCloud account, maybe read the posts above?
