Reminder App on Mac stopped working shortly after migrating to new Mac

Hi all,

short update.

I had a very nice phone call with management support from Ireland yesterday evening.

We tried all the above, like sing in as other user, safe mode, disable iCloud sync, enable it and so on...

All without success.

Interseting is, when I create a new user and sign in with Apple, the Reminder App does work and also syncs happily. So the Reminder App in General seems to work on the macOS installation, but not within my account.

So finally the conclusion is:

Either during the migration from the TimeMachine Backup the Reminder-App got damaged or the Backup on my TimeMachine Drive is damaged.

According to support I have now two options:

• Reset the MacBook completely, set it up as 'new' and then again migrate from the same backup

or

• Reset the MacBook completely and start from scratch by creating a new user and then manually migrate the files from the backup (Which will take a weekend or so to get everything back at the stage where I am now, with all my customizations etc.)

I will first try to restore it from same backup and see if it works. If not, then obviously I have to go for the fresh setup and manual migration :-(

Both are quite time consuming, but thats the only way to go.

The person on the support phone told me, that he has never seen something like this before. The support was great, friendly and we had spent a good and nice hour on the phone, unfortuentely without success.

I will keep you all updated once I have tried the above so if one of the above works, we can post it and mark it as final solution.

@TKPC.KSE thanks for reporting, interesting to hear that I am not alone… but sad

Hi all,

I tried option 1

• Reset the MacBook completely, set it up as 'new' and then again migrate from the same backup

no success, problem still exists.

i do not want to set up a complete new account and migrate all manually, this will be a whole weekend to set it up as I am used too… don’t want to spend so much time.

let us hope Apple developers find the bug and hopefully going to fix it somehow.

Hi JovonaP.,

thanks. I just created a new user and started the Reminders App. It works fine. I did not set up the second user with my apple id, just created a new user from the scratch and started reminders and it shows something.

It is not empty:

so it seems to be only with my user account there is something wrong with the Reminders app.

Dear Sean_B1,

thanks for the quick answer, much appreciated.

Safe-Mode did not resolve the issue, still havgin the same problem. I tried it even two times, booting into safe-mode, just to make sure.

Here are some additional informations:

System version: macOS 12.5 (21G72)

Kernel version: Darwin 21.6.0

Hardware: MacBook Air (M2, 2022), 16 GB RAM, 512 GB SSD

How this occured:

I migrated from a MacBook Pro 2016 to this new MacBook Air.

The MacBook Pro 2016 was also running on macOS 12.5

Migration was done using TimeMachine Backup from an external SSD drive.

All went fine during migration, no issues, all services running well on the new System, except 'Reminders App'

Any suggestions?

Cheers

Thanks Henderson_86,

did not help, I tried to remove all login items and rebooted, same problem.

Going to contact support and hopefully will post the solution here when it is fixed.

Thank you all, will keep you updated.

Not for me.

Still my Reminders app is not working, showing a blank screen (as in my first post).

I am still running on macOS 12.6 (21G115)

I have high hopes, that in macOS 13.0 it is going to fix itself.

Let's see
