    Upgrading to Mac OS Sierra may have bricked my MacBook Pro 2010 (running a SSD) and I'd appreciate some help resolving.

    I downloaded Sierra via the App Store in El Capitan and started running the installation wizard. All seemed fine - the MBP restarted itself and I was given a screen saying "insufficient disk space to install, click here to restart". So I did.

    The MBP restarted itself and since then has been stuck on the grey/white screen with the Apple logo and progress bar stuck around 75% - overnight.

    Here are the real problems -
    1) I can't boot in safe mode by powering off, repowering up and hitting SHIFT (left or right) when I hear the chime. It just gets stuck on the progress bar.
    2) Similarly I can't boot in recovery mode by doing the same and holding down CMD+R. Again gets stuck on progress bar.

    Any thoughts??

    If you have a bootable usb of el capitan or sierra you could boot up from that and restore the computer to a time machine backup.

    Did you make such a bootable usb?

    And did you make a backup?

    If answer is no to both then maybe the only option is internet recovery:
