Problems installing on OS X 10.13.6

Situation
Trying to install 5.0.2 or 5.x on High Sierra running on a MAC. I have MAMP 4.x running as a local development server and that all works fine. Had a little trouble, but it looks like the problem was the username and pass have to be over 11 characters in length or more. Would be nice if it said that on the install page. Got through, but then I have an error saying that:

Notice: Undefined variable: forwardIp,

and then the headers were sent with the error output to screen.

I think that is in sanitize.inc.php, line 18, function collect. You might have to set $forwardIp to an empty string or null or something to prevent that from happening when $_SERVER[‘HTTP_X_FORWARDED_FOR’] is empty. Getting a bunch of other notices, so I should turn off error reporting to the screen.

Hi @Stephen_Douglas_Scot ,
Ensure you have the following php settings:
https://www.open-emr.org/wiki/index.php/FAQ#What_are_the_correct_PHP_settings_.28can_be_found_in_the_php.ini_file.29.3F
(and restart apache after make the changes)

Thanks. It did install. I did change those settings in php.ini before installing. Still get a few notices only really.
