Microsoft has updated its latest Office suite for the MacBook Pro with Retina display, bringing sharpness back to the table.
Blur, be gone!
In a blog post, Microsoft stated that all you have to do is hit the Microsoft AutoUpdate program to get things going (alternatively, if you're already patched up to SP1, you can manually patch from here).
If you don't see a difference after the update, you may need to force OS X to reload the .plists, a process which Topher Kessler outlines on CNET.
While everything should be a lot crisper afterwards, you may find that not everything has been scaled appropriately for the Retina display.
