I have to say I love being able to use my iPhone as my microphone on my MacBook Air for Mac Dictate. It is annoying that sleep state is not reflected on the phone, but the biggest problem is that if you have a screen time lock selected, it will quit communicating with the computer when you hit that time mark. It is disappointing to me that this problem has been discussed for over a year and not been addressed. Still, it is easier than carrying an additional microphone or using the unsupported internal microphone.
