This is not a language related question, but how does one type an Okina? (On a laptop) Otherwise I will constantly be marked wrong.

Installing the whole keyboard will let you use the kahakō easily as well. I'm sure there are ways to install a couple of shortcuts without the whole keyboard but I find it simple enough to switch keyboards as necessary on OS X.
I also have the Hawaiian keyboard enabled on my phone but I can't remember how I did it. It might have been one of the methods here: http://niuolahiki.ahapunanaleo.org/mod/page/view.php?id=6745
If you are on iOS, just go to the Settings app under General->Keyboard->Keyboards->Add New Keyboard...->and scroll down to Hawaiian. When typing on your device, tap the globe icon on the bottom left corner of the keyboard next to the numbers button to switch languages
I'm sorry I am unfamiliar with Android operating systems.
How is this pronounced? (Iʻve been pronouncing it [ A-o-ley ] but it feels wrong.)
"A ole", how it was explained to me, you would make all the sounds that each letter makes, but blend them together (quickly and smoothly) anything with the kahako over the letter, hold the vowel sound out a little longer. Okinas have a brief pause
There is a language with macrons(ā) and (š) kinda letters if you ever need them. Its called Latvian. Just a piece of information becuase in hawaiian theres macrons to.
