As the title says does Mimo support Apple ProRaw for stills?  If not can the Osmo Mobile be used with for stabilizing Apple's camera or other 3rd party camera apps?

Hello there Dr Tone. Thank you for reaching out and for this inquiry. I am sorry to say that the DJI Mimo application does not support Apple ProRaw. In addition, you may use the DJI Osmo Mobile product as stabilizer, which means you can use original camera without the DJI Mimo Application and use the DJI Osmo Mobile product to provide more stabilization. Thank you.

You dont have to use the Mimo app,  you can still use the apple camera app if you want.
