Cannot setup SMB sharing on Yosemite
I just did a clean install of Yosemite and am slowly recreating my previous setup. However I cannot get SMB sharing to work.
I turned File Sharing on, my Macbook drive is listed under shared folders then I go into Options and enable SMB. BUT in the section of this window called Windows File Sharing where I am supposed to select the account to be used for sharing (and then enter my password) my account is listed but greyed out and cannot be edited.
I booted back into my backup from before I reinstalled and the setup looks identical except the section is editable.
See screenshot (I have blanked out my account name but it is there). But see I cant click the On button - the whole section is greyed:
Is there something else I need to do to enable this section? Or is it a Yosemite issue?
MacBook Pro with Retina display, OS X Yosemite (10.10)
