The new system on my new ipad pro doesn't support Photo sync

I just got my new ipad pro 11" there are tons of changes that seem to be problematic. I have an imac mini which I've been using for the last 4 years, and I still use it fine.

after I bought this new ipad pro, I found that the usb connector is changed to USB C and it doesn't connect to my computer.

the first problem was that I could not find a way to restore my ipad from the old back ups on my computer. I tried to find a connector finally to be able to connect it to my computer then it could not finish the back up, so I ended up having to restore the iphone back up on icloud instead!

now it's the most part that I really care about. I store all my pictures on my computer, but the photo sync feature seems to be disabled on this version. How can I make it work to sync my pictures from my mac to this new ipad?

I really need help.

Thank you
