Can't place system folder above root on Mac?

[eluser]Deadly[/eluser]
My folder structure is:

Code:

/Users/me/Sites/mysite
--- /application
--- /system
--- /web_root

index.php is in web_root with this specified for $system_path:

Code:

/Users/me/Sites/mysite/system

No matter what though, I keep getting this error:

Code:

Your system folder path does not appear to be set correctly. Please open the following file and correct this: index.php

Can't find a way to fix this at all! Help?

Have you updated line 59 of index.php so that it points to the right relative path of the system's folder?

Code:

$system_path = 'system'; // shouldn't be purely system here ;)

Hi there,
Yes, per the post above, I've updated index.php to:

Code:

$system_path = '/Users/me/Sites/mysite/system';
