Izotope:

is a complete mess within Pro Tools. I managed to get RX Connect and Monitor to work for which is of some use.

Only certain components of Ozone work. The Low end Focus and Ozone 9 AAX plugins crash every time, whereas vintage limiter and others seems to work.
Don't try wrapping AUs or VST with Blue Cat as this doesn't work either.

Celemony Melodyne Studio:

Can't transfer audio into plugin. Can't import or open sessions with active Melodyne's in them

D16:
Nothing works

PSP:
Only ARM coded Plugins work

Elastic Audio:

Can't seem to open sessions or import tracks with Elastic audio enabled in them as per audiorepublica

Acustica:

Plugins run but cause overloads easily even at high buffers
