Why is macOS Ventura Not Working with the Garmin Aviation Database Manager?

13.2.1 macOS Ventura has now been released. This resolves a compatibility issue with the Garmin Aviation Database Manager application. Please update your Mac's operating system to macOS Ventura 13.2.1. to resume using the Garmin Aviation Database Manager. 

Here is Some Background on the Issue and How to Correct the Problem:

• Apple decided to restrict access to an API in the Ventura OS that Garmin used to update database SD cards and thumb drives for avionics. The 13.2.1 version of the Ventura OS release resolves this issue.

Solution:

• Update macOS Ventura to 13.2.1
• How to Update macOS

For those Unable to Update to macOS Ventura 13.2.1, See the Workaround Below:

Note: This should only be needed for new SD cards or cards that have been recently formatted.  If the card is currently working, do NOT format the card.  If the card is formatted, the necessary file information will be deleted.  The workaround will then be needed for each card that is formatted.  This means that if you format three SD cards, the workaround will be required on each card if working with macOS Ventura.

This process is very technical and should only be used if you are a Mac expert with experience with the Mac Terminal.

Instructions: 

In the Ventura operating systems below 13.2.1 we have found some issues that cause the current version of Garmin Aviation Database Manager to give an error code showing this message or a message with a 272 instead of 287:  

This is the workaround for customers encountering errors similar to the ones listed above. Ensure that the Garmin Aviation Database Manager is on the latest software version 22.12.8 or newer. If you are unsure of what your software version is click on the Garmin Aviation Database Manager tab on the app menu bar. Then click on About Garmin Aviation Database Manger and the version will be listed below.

• Note down the DEBUG messages from the Garmin Aviation Database Manager mentioning a raw disk file path ( /dev/rdisk2s1 in this example), keep this file path in mind as we will need it later.

  *This is the name of the removable drive's pathway

• Open the Terminal app and enter the following command:
• 1. sudo chmod 666 RAW_DISK_FILEPATH
     1. Example: sudo chmod 666 /dev/rdisk2s1 

*The chmod command changes the permissions on the SD card so the Garmin Aviation Database Manager can access it.

• Enter your admin password and hit Return 

a.  The command will run but will not output any message if there was a success or failure.

• Return to GADM and try to update the card again, it should work now.
