Contao 3.5 in Xampp on Mac

Hello,

For testing, I just installed Xampp on my Mac.

I downloaded Check in a subfolder of htdocs to install Contao. But Check tests give me some errors :

Quote:

- php process isn't allowed to create files
- test folder is proprietary of deamon (should be root) with chmod 755
- test file is proprietary of daemon (should be root) with chmod 644.

How do I change proprietary from daemon to root ?

Thanks.
