Hello to yoiu gail from maine,
I am quite delighted to get a response to my question so soon. Okay, if I understand you correctly you don't care so much about thatch aspects of my computer but rather what I am working on with it. As of these several months I have been trying to watch iTune movies I purchased on my projector. I can't do that now. I went to Apple Care chat many times with this and I also placed several phone calls to them with this same issue. The answer keeps coming up[ the same. My computer MUST be able to display Air Play mirror reimagine. For some reason and I don't know why my computer will not or does not comply with a duplicate or second screen feature. My Apple is a Macbook Air (early 2014). All I can find after spending a lot of time at my friend Google's place is that if I purchased Apple Tv this feature most likely would work.
Anyway, thanks for the courtesy of a reply and it's is always a pleasure hearing from the gals.
James
