Apple - Remove VIP mail box from sidebar in Mac Mail

I found what worked was:

1. Remove all VIP contacts
2. Close Mail
3. Reboot the machine

Upon reopening Mail, the VIP section in the sidebar is now gone.

UPDATE - At the time of writing this initial post i was running OSX 10.9.

Got this working in OS X 10.10, Yosemite:

1. Close Mail.app.
2. Go to ~/Library/Mail/V2/MailData/.
3. Edit VIPSenders.plist and remove all the senders.
4. Save the file.
5. Select the file and press Command + i to see information about the file.
6. Check Locked under general info.
7. Reopen Mail.app.

OS 10.11.6 Open the email in the VIPS folder. Click the star next to the "From" email. That removes it from the VIPS folder and the VIPS folder goes away. If you have more than one email in the VIPS folder, you will need to repeat for each email and then the VIPS folder goes away.
