MacOS – Apple password verification showing weird characters

macos

I recently had to reload Yosemite on my Macbook Pro Retina (Mid 2014)
and after booting it up this morning and allowing a application to run, my password box looks like this.

Any help would be appreciated.

The Font Database is corrupted, you can rebuild it. (NOTE: make backup before performing this)

sudo atsutil databases -remove

And then repair permissions:

sudo diskutil repairPermissions /

After it's finished restart your machine.
