No RTAS plugins or AAX32 bit plugins will work in PT11 and up. There is only one format that works with 11 / 12 / 2018 etc and that is AAX64 bit format.

I dont know what hosts you can buy to use rtas format inside PT11 but VST and AU on Mac you can use Bluecat MB-7 MK2 or Patchwork both cost money, around $100 normally but lowered deals can be found online for one of those sometimes.

So PT11 and up No RTAS plugins will work without above workaround.
