MAMP installed OK. Seemed to work pretty well, except for the fact that I could not get it to enable error reporting. Had to find some PHP code to add to each of my docs to get that to work.
The MySQL server stopped turning on after the first day of use. Wasn't using it anyway so I ignored while I finished the PHP course. couldn't find any easy fixes, so I unistalled and reinstalled. Again worked for one day an then stopped turning on. Downloaded WAMP instead. So far so good, but it does have a very different user interface. If anyone has experienced similar issues with MAMP and has any easy fix, I'm all ears.
