When I click Mastering on my Stereo Out, it does nothing and stays greyed out. When I select Mastering Assistant from the Mix menu, it also does nothing. Is anyone else experiencing this frustration and/or find a solution?
MacBook Pro 15″, macOS 13.6
I have found that the Mastering Assistant will not work if ANY of the outputs are anything but stereo out. That being said... it appears Mastering Assistant only works in Stereo Out format. Hope this helps.

Still isnt fixed
It just worked for me god, it was so simple but hard to guess, I onle clicked on the Mono-Stereo two circles intersected appearing option to like ''restart'' that function, and mastering assistant finally appeared.
I had one channel with surround selected for the output for no reason
By switching it to stereo the assistant finally appears
I can't even find that plugin at all I've updated the software and that plugin is nowhere to be found
I have a 2017 15" 2.9Hz i7 MBP.
I did figure out that if you remove all other plugins from Stereo Out, then Mastering Assistant will then become available. In the support article it shows a screenshot utilizing a compressor just before Mastering Assistant, but removing all of that is the only solution I've found for making it work.
Since the Mastering Assistant needs to control the output, no, you can't put anything there before using it. It needs to apply units based on its analysis of your work. You can do tweak it all afterwards. So, you can master the piece yourself manually and be done, or you can use Mastering Assistant FIRST and then tweak afterwards, but not really do both in that manner.
What Mac have you?
It worked for me as follows:
Stereo out channel: Settings > App Presets > Select an app preset (e.g. Basic). Then press Mastering > Mastering Assistant opens.
Hope I could help.
Let's make sure everyone knows how it actually works and how to apply it, rather than taking pot shots in the dark.

This is the window I get when trying to open Mastering Assistant
It's not really a plug-in that you can load in. It only appears in the Stereo-Out channel in the mixer.
