LC 6.5.1 and 7.04 don't work any more with the NOOBS standard installation (Raspbian Jessie).
For Raspberry 2 this is no problem since the 2015 version Raspbian Wheezy still runs stable on it and LC works with that. But Raspberry 3 (and RaspberryZero?) are not supported any more by Raspbian Wheezy.
The following may also work for the Raspberry Pi 2. But I'm not sure about the support of peripherie -- I didn't test this variant until now.]]
Searching for another solution for Raspberry Pi 3 B, I succeeded with
Ubuntu 15.10 MATE.
There is a made-with-love version for Raspi 3 available at https://www.raspberrypi.org, only the on-board-bluetooth is (not yet) supported, the on-board WIFI module works already.
I runs fine, I like that even more than Raspbian. Disadvantage: Mathematica 10.3 is only available for Raspbian -- I really can't understand, that this is connected to OS and not to hardware??
It is important for installation to follow exactly the instructions given at https://www.raspberrypi.org, because there is no "raspi-config" in Ubuntu MATE. (Mac users can write the img to SD card analogously to the instructions given for Raspbian, then proceed with general instructions.)
- There is no need to set framebuffer depth or alpha: what we need is already set in Ubuntu MATE.
- For transparency (windowshape) simply install xcompmgr and it's autostart as described in another thread in this subforum, write "MATE" instead of "XFCE;LXDE" in the last line of the code there.
- Hint: If you need to disable overscan or enlarge to gpu_mem=128 or force HDMI-plug: There is still /boot/config.txt for editing available.
Especially LC 6 is pretty fast, that's why I meanwhile rank final LC 6/7 versions before an LC 8 version for Raspbian on my wishlist. And this is also, perhaps, not so difficult as to have LC 8 ...
Ask if you get a problem, I read a lot of valuable hints from "raspi-nerds" last day (and night).
