Ampps For Mac – Update to 3.3 Manually Without Re-installing
Ampps is a fantastic piece of software if you want to run a testing server but upgrading on the mac has always been pretty awkward. The first time I upgraded, back when I was a Mac newbie, I deleted all of my files by accident! Luckily I had created a backup first. The good news is Mac users can download and install the update from a compressed file so there is no need to install from the disk image again.
