My mac froze earlier today and I forced it to reboot (involving several force quits and eventually holding the power button). After it started up, everything worked except MAMP Pro. When it starts, it doesn't report any errors but just hangs on starting MySQL, with a spinner next to it indefinitely.
I've tried uninstalling and reinstalling to no avail. However, regular MAMP works just fine. I've deleted and reinstalled /Library/Application Support/appsolute/MAMP Pro several times, but maybe there's other files I'm missing?
Fixed it by overwriting /etc/apache2/httpd.conf with /etc/apache2/httpd.conf~original
