So I'm still comparing tonight my 2015 to my 2016 and going back and forth watching an HD movie in my iTunes library, each time going back and forth between models, watching for about 10 mins then closing lid (sleep) then opening the other and vice vs each time not closing out of iTunes but just minimizing it. So I've been watching it on each model going back and forth about 3 times and the 4th time I opened the lid to the 2016 launch iTunes go to my movie library and click on the movie, it asks me do I want to resume or play from the beginning, I chose resume and the moment I click resume it force closes iTunes with a window do I want to send a report to Apple unexpected error. So I try to re-open iTunes, same thing the minute I click on resume my movie it force closes.
So then I say ok I'm going to play some of my music in my library to see if it plays and it doesn't but this is what I just noticed. I have lag I didn't notice before. When I'm in my albums library and I click on an album artwork to display the tracks under, it lags loading the tracks below. I'm thinking wait this looks like lag so I keep doing it clicking on the album so it displays the track listing right below and sure enough there is very noticeable lag.
So then I go to my 2015 and try it, go to albums and click on the album and it's very very smooth, no lag, so then I tried other albums and it's the same very smooth transition. Then I go back to my 2016 and try other albums and just as soon as I click on the album it lags loading the tracks below it. I'm posting this because I have not noticed this before.
I just now tried again on the 2016 to start the movie again in iTunes and I still can't get the movie to start playing the moment I hit resume playing it force closes. It's also force closing when I try play the movie from the beginning. I'm not sure how to get the movie to play again. I also have both authorized so that's not it and like I said it's been working back and forth for about 3 times perfectly so why is the 2016 force closing iTunes when I try to play the movie again? And why am I seeing lag in my albums when I click the album cover? I also can't even play any music the moment I click on the song it force closed iTunes.
[doublepost=1486781925][/doublepost]So I just did a restart (2016 model) and opened iTunes and it still is force closing the moment I click on resume or playing movie from the beginning. So then I did a complete shutdown waited a few minutes and then opened iTunes and it is still force closing when I click on either resume movie or play from the beginning and it also won't play my music just force closes. I have no idea what to do other than re-load iTunes which I'm not doing tonight. It's looking like I might be better off sticking with my 2015.
[doublepost=1486782579][/doublepost]Ok so I decided to de authorize the 2016 iTunes account and then sign out of iTunes. I then re- signed in and authorized the 2016 and that fixed it. This is so weird why it forced closed iTunes like that but at least it's fixed and it plays my music and just resumed my movie where I left off.
However I am still seeing lag when in the albums tab and it displays the tracks under the album there is very noticeable lag.
