Hi rkueny,

this is an permission issue. Your user does not have access rights to the temporary directory (in my case /var). Run ps aux | grep httpd to see your user and add this one to the /var directory.

        echo shell_exec('whoami');
        var_dump(sys_get_temp_dir(), 'assetic_less');
        var_dump(tempnam(sys_get_temp_dir(), 'assetic_less'));

The last statement must NOT return false. Output should be something like:

nobody
string(48) "/var/folders/ps/9n4sxsdn2l7dhwrl6n659vgcv56ml7/T"
string(12) "assetic_less"
string(75) "/private/var/folders/ps/9n4sxsdn2l7dhwrl6n659vgcv56ml7/T/assetic_lessUqROwh"

Best,
Robert
