Hello Eric!

Don’t fret - our developers are still working on it. We had issues with Simlink on Big Sur as well which have now been solved. Hopefully, the solution will apply to the FMS Data Manager too!

I will advise as soon as our developers have made more progress!

Happy New year! :tada:

Hello Malte ! I hope you’re doing well !
I understand that this issue is not the easy one and I’m sure the developers do their best to solve it. In the mean time, is there a possibility to update manually the FMS data on my add-ons ?
Thank you and best regards.

Of course! Should have told you about it from the beginning, my bad sorry.

You can manually download FMS Data for any product from the FMS Data Manual Installation dropdown in your account downloads on!

Do you still experience this problem with FMS Data Manager on Big Sur? I am unable to reproduce the issue with the latest version installed. If you do, please follow the steps below:

  1. Open finder and press Cmd ⌘+ Shift+ G
  2. Type ~/navigraph/fms-manager/logs in the prompt that shows up
  3. Attach any relevant logs found in the folder (presumably the latest one) to your next post

Kind Regards,
