1 pointThx Fusion! For those who want to replace the original DU by the patched DU, just delete the old one and ditto the patched over the recovery or install terminal. (without typing sudo) -> into -/Applications/Utillities -> after ditto, wheel it sudo chown -R 0:0 Disk\ Utility.app -> after restart OSX, fix permissions sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume / Cheers NewBit
1 pointHi fantomas, The file is definitely from Yosemite 10.10.5 - see post#12. Maybe it got corrupted since I uploaded this morning from USB drive off a Windows box (I'm at work at the moment ). I'll check when I get home and upload from OSX. EDIT: Problem solved. After you have downloaded and unzipped the file, you need to let root:wheel take ownership of the app ie sudo chown -R 0:0 ~/Downloads/Disk\ Utility.app before the app will run.
