to let you know beforehand nope, I haven`t saved data before for about 2 months... (shouldn`t mean, those aren`t vital) Hello, when starting my mac mini (os x 10.4.11) a black screen appears with: /etc/master.passwd: No such file or directory -sh-2.05b#IOBluetooth HCIController: : start Idle Timer Stopped Before that started to happen, I binned several data from an admin account (for reasons, of course, as I need space to fix another problem) among others I deleted mail, what else I don`t remember, it`s several months ago) Switched back to my standard account (also admin) and recognized a ? above the mail icon. If memory serves me right, nothing else noticable happened when I continued the session. Shut down later, (eventually I shut down soon), next day when starting- above mentioned. a right amount of hints might be usefull. thanks in advance.
