From the comments on the release page I wrote:
@Everyone having permissions/ownership problem:
That error happens when permissions were not correctly enabled during the file transfer… And yes this is a symptom of using tonyfail crap (you do know he has no real programming skill other than copying and pasting other peoples work and passing it off as his own right?) – there are a few things you can try however before you simply wipe it out and stat over.
As I said in a previous comment the first thing u can try is:
sudo chown -R 0:0 /Volumes/Your Installer/
Note: This should not be necessary as the app will enable permissions on source and destination volumes prior to transferring the data and it preserves all permissions, attributes and ownerships – I only suggest it as a last resort.
That isn’t ideal, but it may at least get you booting, at which point you can at least get things installed and have a clean start. I do suggest using the minimal /Extra/Extensions you can to boot your system and then layer by layer add one thing at a time until you have the rest of your hardware working – that way you can easily tell when something is working and when something is not – makes finding the source of a problem much easier.
For the chown command to work you must first enable permissions on the device, this should have when the command was sent from myHack during the creation of the USB stick, it is unclear why it failed without you providing me your console logs to review – you can enable permissions from the terminal by typing vsdbutil -a /Volumes/yourinstallervolume – then run the chown -R 0:0 /Volumes/yourinstallervolume again.
I also suggest you run diskutil repairPermissions / prior to doing this or to attempting the following…
Ideally, you could just wipe out the boot sector, repartition and reformat the usb stick and try to start over – this has worked for most people.
