MAMP

I use MAMP for my local Backdrop development on MacOS.

If you would like to do the same, first download the most recent version of MAMP and install it locally. When you are done, you should have directories for both MAMP and MAMP PRO in your /Applications directory.

To run the application, double click MAMP.app inside the MAMP directory. Once it's up and running, you should see a MAMP widget with a cute elephant icon.

Let's start by adjusting the preferences. I like to run MAMP on the standard ports for Apache and MySQL. MAMP provides it's own ports, and by default uses these instead.
