    I have my system on raid1 and so I can't boot to Safe Mode for OS upgrade.
    I'd like to hear opinions & experience about this.

    1) Is it possible to
    a) delete raid1 in Disk Utility
    b) Safe Boot to one of the disks from raid1
    c) Upgrade OS
    d) rebuild raid1 with upgraded OS

    2) Is Safe Boot still good idea for upgrading OS in Leopard?

    3) Is deleting & rebuilding raid1 for OS upgrade worth for all the trouble?

    Safe mode is generally unnecessary for system upgrades unless you have problems - certainly I've not needed to work around the RAID1 mirrors I use for upgrade purposes.

    In your situation, I'd recommend downloading the combo updater, then repairing permissions and rebooting normally before install. After installation, repair permissions once again and you should be fine - the combo update is generally a more reliable experience than using software update.

    Ok, thanks.
    I've had pretty big problems with FCP's instability & rendering garbage, but I'll try be brave and see how it goes without safe boot.
