I finally got it working again.
When I re-installed RM (version 2) I noticed that the option to install the driver for 10.9 and higher was grayed out.
I had a (sorta) clean install of El Capitan on another bootdrive, I tried installing RM 2 and then it did gave me the option to install this driver...
Back to Sierra, still the same. Then I tried an older version of RM (1.3 Beta), This did install the driver, than I re-installed the latest version of RM an now it´s fully working as it is supposed to.

After upgrading to a newer Mac, Rig manager no longer recognizes my Kemper.
I re-installed RM (including an update), updated the Kemper to 5.3.1.13085, but the problem remains.....
It's not a faulty USB port or cable, as I can "see" my Kemper under Hardware>USB>Profiler (including correct serialnumber)
Anyone got any suggestions??? Is the a Sierra security setting or something??

What speakers/monitors do you use?
Happy Kempering
Those are Soundcraft Spirit Absolute 2.

Welcome, Henry.
I agree with @Armin - you must Profile the J-Station before you sell it. There was much love for that thing back in the day, especially for cleans through to mild crunch.
I sorta only used the Rectifier amp, clean to mild crunch in not really my thing....

Hey there,
I'm Henry from the Netherlands, I'm not a Kemper owner yet, I hope to have my Kemper by the end of this month.
At this time it will mostly be used at home for recording/re-amping.
Ohh, I now use a Johnson J-station (and some amp sims more recently), but that's in a different league.
