    I have a MBP 15" late 2011 running OSX 10.10.4. Since yesterday I can not boot it, the grey progress bar stops at about one third or half the way.
    After reading some support files from apple I first tried to boot in safe mode which did not work either and then bootet to recovery mode. DiskUtil found some errors it could not fix so I bootet to single user mode and used fsck. This found problems with a wrong number of thread counts and in the attributes. Both could not be recovered by fsck or fsck_hfs using -Rc or a.
    A friend told me DiskWarrior could deal with these problems so I ordered it and expect it to be delivered tomorrow.
    And here is my question:
    I have never used or installed DiskWarrior before. According to DiskWarriors Webpage the USB-fladh drive can only boot on Macs originally delivered with OSX 10.4 to 10.6. Mine was delivered with 10.7. can I boot with DiskWarriors Flashdrive though or what can I do. If I can not boot DiskWarrior directly is there any chance to boot into recovery mode an access it from there? How?

    If you read further on the Disk Warrior requirements page, the next sentence is:
    "If you have a newer Intel Mac, you can use the included DiskWarrior Recovery Maker to update the DiskWarrior Recovery flash drive to start up your newer Mac."

    The only problem is you have to have a working/bootable Mac to run the DiskWarrior Recovery Maker app. A.Borque may need access to another working Intel Mac. Otherwise A.Borque may need to contact Alsoft ASAP (even before receiving Disk Warrior) to determine what help they can provide.

    Rant Alert: I also have Disk Warrior and I think Aloft's current delivery system has a major weakness since it does not support Intel Macs out of the box. They should at least have an option to order an Intel version.

    Exactly that is the problem. Aside from recovery mode I do not have access to any working Intel-Mac as all my local contacts are on Win.

    There is a Time Machine backup. But I habe never used Time Machine to do a full restore. And until now I thought it is always easier to try to fix the problem with reasonable efforts than setting up a system from backup.

    Here is the answer for Macs delivered with OSX 10.7 and newer.
    DiskWarrior arrived today and there are instructions in the box how these newer Macs can be repaired althoug the USB flashdrive can not be booted:
    Connect the USB flashdrive to the Mac. Start it into recovery mode. Open terminal there. Run /volumes/dw/go. DiskWarrior starts.
    PS: DiskWarrior repaired my damaged HDD within about 10min and everything works fine again.
