Automatic Update don't work

Few hours ago I wanted to activate the auto upgrade on WordPress for my webpage local on my computer via mamp. I read the codex, and, did as I was told:

1. I went to the wp-config and added this line on the end of file

define( 'WP_AUTO_UPDATE_CORE', true );

2. I am using .git on this installation so I added this line aswell:

add_filter( 'automatic_updates_is_vcs_checkout', '__return_false', 1 );

3. I installed Background Update Tester-plugin which told me that anything should be alright:

PASS: Your WordPress install can communicate with www.remarpro.com securely.
INFO: The folder was detected as being under version control (.git), but the automatic_updates_is_vcs_checkout filter is allowing updates.
PASS: Your installation of WordPress doesn’t require FTP credentials to perform updates.
PASS: All of your WordPress files are writable.

Now I waited a few hourse, loaded the pages, relogged into backend, changed browsers, emptied cache, BUT still I am 3.9.1.

Question now:
-What did I do wrong?
-Any different solutions to get a fully automatic upgrade on wordpress?
