“xampp-osx-8.2.4-0-installer” cannot be opened because the developer cannot be verified

I have just started formally learning PHP, and the prerequisite for effective learning is installing a local PHP development environment. What is better than XAMPP?

I went ahead and downloaded the latest version of XAMPP for Mac (Yes, I use Mac as my primary machine), and when I opened the .dmg file, I got this error:

“xampp-osx-8.2.4-0-installer” cannot be opened because the developer cannot be verified.

This item is on the disk image “xampp-osx-8.2.4-0-installer.dmg”.

Are you in the same boat? I have recorded a short video on how I fixed this and was able to install XAMPP on my Mac:

Prefer written instructions? Here’s it:

  1. Click on Cancel button in error dialog box.
  1. Open Settings.
  2. Select Privacy & Security in the left side.
  3. Scroll down and under Security, you will see entry for XAMPP with Open Anyway option. Click on that. See the screenshot below:
  1. Enter your Mac password and give the XAMPP installer permissions to download folder or wherever the installed is located.
  1. When the installation is finished, you will see the screen below. Click on Finish to launch XAMPP.

Got any questions? Feel free to ask me!

P.S: I will be documenting my whole PHP learning here, let’s master PHP together 🙂
