    I am trying to update my Macmini5,2 to version 1.4.
    Each time I do the update it goes to the end and asks me to reboot. When I boot back up and check for updates, the update is still there.

    What can I do to fix this?
    My Boot ROM Version is currently MM51.0075.B00 if that helps.

    Thanks in advance!

    Is your partitioning scheme MBR perhaps? (did you reinstall?) Works only from GUID and internal HDD. (been there, done that) If everything is working fine then perhaps you might not want to update - I have issues with Windows after the update :-(

    Thanks MJL, I think it has something to do with my partitioning.
    I manually created a 2nd partition and after looking at my logs, it is saying something about the partitions when I do the update, strange that it says it has worked when the logs say it had errors.

    I'll be sorting it out later this week with a fresh restore from backup with only 1 single partition.

    Try downloading the EFI update from Apple Support instead of Software Update.
