On Behalf Of User @Marcal303
I can confirm that that the Traktor Kontrol S3 Firmware for MAC OS Does not update.
I do not think that the correct firmware version has been uploaded for MAC Users.
I had assisted Marcal303 remotely earlier & can confirm that this version (Link Below) for MAC OS is not version 1.2.0

This Is The MAC OS Update Details
The same information is presented in the Windows version as well.
I am honestly not sure if the Dev team will ever look into this but for users who own an S3 Unit, My best advice - 1 of 2 methods
1 - Download a Windows OS Iso & run it virtually ( VMWARE or alternatives ), download the demo of Traktor Or install licensed version of traktor on the virtual machine & update the firmware that way
2 - Try Get a windows laptop, Install Traktor pro & update the S3 Kontrol unit that way.
This should resolve MAC OS users until One Day the NI Dev Team comes to terms that alot of users are experiencing major problems.
Here is the link to the Windows Firmware Version to assist.
