Hi, Thanks for all the help. Whilst deciding which OS to install I was 50/50 Mint vs Zorin. I liked Zorin so far so have been using that. But out of curiosity I tried Mint on the Macbook pro and it enable the brightness controls. as this computer is for one of my kids an they will only be using Firefox for school then I'm just gona stick with the Mint install for that one and keep Zorin on the others. It is a weird glitch...
Another interesting fact - whilst troubleshooting I tried using Zorin Lite which is currently OS 15. That had a "settings" box that had Boot Options as one of the things you could play with. It had all the Grub options and stuff. It seems they got rid of that option for OS16.
Unfortunately i was already half way through installing Mint when I saw that so I didnt get to try it.
Thanks again for everyones help.
