DSD256 with problem

I have a doubt, using the Mac with IOS I can use it without a problem until DSD128.
When I try to use DSD256 it works, but it fails.
I use the DAC of the Oppo 205 that goes up to DSD256.
I’m using a Mac mini I5 with 8GB of memory, an exclusive computer for audio.
Is this a problem with the processor or Audirvana?
