My Site creation stuck at “We’re almost ready!” - SP2013

After changing the MySite host to a dedicated web app, the user's MySite did no longer get provisioned after visiting the users page.

It turns out that the managed path "personal" was not created automatically, as it is in SP2010.
Here is the solution:

• Create a new web app
• Create a site collection at the root using the My Site Host template
• Assuming you want users’ MySites to be created at http://mySiteHost/personal/[John_Smith], create a Managed Path for the web app. The path should be personal, and the type should be Wildcard Inclusion.
• In User Profile Service Application, set My Site Host location to http://mySiteHost, and Personal Site Location to personal.
• Enable Self-Service Site Creation for the web app
