After installing Mac Sequoia 15 (15.1 as well), the XAMMP app stops unexpectedly. I also tried MAMP. In that case, Nginx is working properly, but Apache is not working. Please, can anyone help me solve this?
For help with setting up apache, please post in the Apple Support Community. Also, I suggest contacting the makers of XAMMP and MAMP for assistance with their software solutions.
