Hiding index.php with CI4 and MAMP

Seems like I've found so many posted solutions to this problem and it took a while until one worked for me.
The only thing that worked for me was to change

Code:

public $indexPage = 'index.php';

to 

Code:

public $indexPage = '';

inside of /app/Config/App.php.

I'm assuming rewriting with .htaccess should work, but I can't seem to get it to.

Are there any problems with using the $indexPage fix?

Thanks.
