Error when setting up the theme in mac

hi everyone,

I encountered this warning/error message when I set up this theme in a macbook.
Warning/Error Message
Warning: imagejpeg(/Applications/XAMPP/xamppfiles/htdocs/test/wp-content/uploads/gk_nsp_cache/scarf3-gk_nsp-4_article.jpg): failed to open stream: Permission denied in /Applications/XAMPP/xamppfiles/htdocs/test/wp-includes/class-wp-image-editor.php on line 391

I downloaded the quickstart package and run. It can be done smoothly when I do in a windows pc. However, I encountered the warning message. I tried to set the permission to read and write for all users but I still get the same message.

Can anyone help me??

I managed to solve this problem by allowing the permission of the entire xammp folder
