We have Kiosks at our University that I created an image for that wouldn't require users to log in. To make this easy I just customized the guest account in Mavericks. Now I want to upgrade to Yosemite, but customizing the guest account is proving to be a bit more difficult. When I try to copy my customizations to the User Template as I did before it works just fine, but I get a message stating "The system was unable to unlock your login keychain" whenever I login to the customized guest account. I feel like the best thing to do here would be to just create a custom user, but I would like to include the feature of user data being wiped on logout, and a logout automatically rebooting the machine and logging back into that User. Does anyone know how I can create scripts to do this? Thanks.
