Hello,i'm "new" on this forum, i had another account that i've lost my e-mail to recover my password

...I've bought a Macbook pro mid 2013,intel iris with 16 Go Ram and i've installed le lastest Backbox in dualboot with Yosemite (don't like at all)...And i'm surprised to see that i don't find any issue on the net and lot of forums i've ran during hours and hours...
If someone could help me and give me some advises it'd be very nice i really don't know how to do...I've tried with a live USB of Kali and keyboard lights worked well so i have lot of questions in my head with no answers ^^,if someone have encountered the same problem explain me your situation and i'm open for a little help

.
Hope someone could help me!
Have a nice wkend.
Regards.
