I have a folder on my Desktop named work where I keep all my php projects. I use MAMP and all projects are set to work on virtual hosts, for example, if I have a project named test I access this project on this URL http://test.dev.
Everything went ok until I updated to macOS Catalina when I started to have this error.
(1)Operation not permitted: Can't open directory for index: /Users/username/Desktop/work/php/development/projectname.
I set the permissions to the work folder and all subfolders to be read & write for my user and staff group, I tried all the terminal permission
commands: chmod 777, 755, etc.
I've solved doing the following operations:
Quit MAMP and all the applications that are using mySql and Apache Server (stop all the instances)
Go to System Preferences, Systema & Privacy, Full Disk Access Tab
Click “add” and go to /Applications/MAMP/Library/bin and add apachectl
Run this command from the terminal: sudo /Applications/MAMP/bin/startApache.sh\
Open MAMP and press the Start Servers button
now you should be able to start your localhost app
I had the same problem like you, and I spent many days to solve it by doing:
stop MAMP, then open terminal and type
sudo /Applications/MAMP/bin/startApache.sh -> then Enter
and then type your admin password to give apache full privileges to start apache. (this way can let MAMP read any files on your Mac, include external drives)
now you can open MAMP and see that Apache is started, then click Start on MAMP app to start MySql too.
