The new version of Reason (Reason Studios, formerly the Propelerheads) drops support for ReWire, but it coexists with Reason 10, which supports ReWire hence no problems for me. I have both versions of Kontakt (5 and the newer 6), so this is not a problem in the sound isolation studio. NOTION (current version) is fine with Kontakt 6 and had no problems enabling it for use as a VSTi virtual instrument.
#MELLOTRON FOR MAC UPDATE#
I also did the Studio One Professional update, and after the update it shows Kontakt 6 as being "blacklisted" and does not verify Kontakt 6 or allow it to run. On a related note, I upgraded to Kontakt 6 last year when Native Instruments had their 50-percent discount sale and so far have installed it to the 2.8-GHz (8-core) Mac Pro (Early 2008) running macOS El Capitan. Next I will do a SuperDuper! (Shirt Pocket) backup of the 2019 MacBook Pro update it to macOS Catalina 15.2 update Studio One Professional and then do the basic ReWire MIDI experiment, which I expect to have the same results.

I repeated the basic ReWire MIDI experiment, and everything is working nicely in macOS Catalina 15.2 on the 2012 MacBook Pro. Once Studio One Professional was updated to the current version, I checked NOTION for updates and there were none so the current version of NOTION is 6.5.470 and is 64-bits, as is Studio One Professional. Then I did the update to Studio One Professional (4.5) with no problems, although the first attempt failed due to network slowness (timed-out or something) but the second attempt was successful and again no problems. I did the update to macOS Catalina 15.2 on the 2012 MacBook Pro with no problems.
