    I'm installing ML as an upgrade from Lion, and my progress bar is at 100% but says -12 minutes remaining... and that number keeps increasing. Anyone else get that? Will it eventually stop? I think I might get forced to hold down the power button, which is never good...

    Exact same thing happened to me, then the bar deceased by half and it said 19 minutes remaining. Now it's stuck there.


    Now it's gone down to 18 minutes. In that case, my best advice is just to wait.

    Same thing, but installed eventually

    I noticed the exact same thing as above. However, after patiently waiting, it eventually installed. So the advice to just "wait it out" is perfect.

    It stays stuck at 19 minutes for a while. It will push through it.

    You could restart, it will simply restart from scratch

    If you wonder what happens when you restart your mac in this case, I can tell you that in my case it restarted the process from scratch. I saw a number of suggestions and considering that my 2 other macs installed without any issues, I simply restarted my mac mini and it's restarting at the beginning (37 minutes left).

    My mid 2010 mac mini took quite a while to install. I went out to run some errands and was gone for at least an hour and it was just restarting when I came back.

    The other macs at home all installed much faster.

    I can also confirm the same issue - Upgrading from latest Lion os with most recent updates to ML on 2011 MBP i5 8GB Ram - Progress bar read 100% with less than a minute... then -1 minute and so on and so on until it read -10minutes, then changed to about 19 minutes remaining... still chugging away. Im assuming it was some tiding up it was doing during install.

    I made a full TM back up and used Onyx & disk utility to ensure my disks and permissions were all ok so im not sure whats occurring i guess patience is the key.

    Thought it was worth while posting so other users know they are not alone!
    cheers all
