I kept getting warnings from my computer that "mysql" etc was out of date on AMPPS so I updated according to this article:
https://www.ampps.com/wiki/How_to_update_Ampps_Manually I followed the directions for OSX. Now, when I try to open AMPPS it says there was a problem and it unexpectedly quit. I went back to restore the old version saved in my time machine and I still can't open.
