Is MonoDevelop all i have to work with on OS X?

So I’m very new to unity, i want to make 2d and only 2d game, I’ve been a windows user for the past 20 years and after a string of bad windows laptops i gave up and bought a nice macbook pro, its absolutely amazing but I’m having to re learn a lot in how it works.

Is there any alternatives to MonoDevelop ? seeing as visual studio is out of the question, i just find MonoDevelop quirky and slow.

You can use Visual Studio Code on a mac.

You can use whatever editor that you feel most comfortable in and works on a Mac. As has been stated, Visual Studio is now supported on OSX. I personally use Sublime Text 2. To show you how to change what editor is used in Unity I’ve attached some pictures below.

First click Preferences at this menu.

Then go to the External Tools sub-menu and click the External Script Editor drop-down menu. Once that has been selected you can click browse to find your preferred application in Finder and set it as your default.

I hope this helps!
