I have three accounts on my Mac: two user accounts and the Guest account. However, at the login screen, only the first user account appears, along with a "Other..." icon, which leads to a username/password prompt. This is OK for accessing the second user account, but how can people access the Guest account? How can I set things up so that all three accounts show up at the login window (without the need to access them via the "Other..." icon)? I should mention that this problem also plagued me under 10.7. UPDATED: solved my own problem... I had this set: defaults write /Library/Preferences/com.apple.loginwindow Hide500Users -bool YES A remnant from when I was tinkering back on 10.5 I think!
