I am running 10.9.5, on a 15 inch, mid 2014 MacBook Pro. I used to be able to use startup disk in system preferences to select a 10.12 USB stick.
I used to be able to hold down the option key and get a chooser at boot time. I even wondered if maybe the bless information had gotten cleared bash-3.2# bless --info . finderinfo[0]: 606 => Blessed System Folder is /Volumes/Sierra10-12test/System/Library/CoreServices finderinfo[1]: 440225 => Blessed System File is /Volumes/Sierra10-12test/System/Library/CoreServices/boot.efi finderinfo[2]: 0 => Open-folder linked list empty finderinfo[3]: 0 => No alternate OS blessed file/folder finderinfo[4]: 0 => Unused field unset finderinfo[5]: 606 => OS X blessed folder is /Volumes/Sierra10-12test/System/Library/CoreServices 64-bit VSDB volume id: 0xD0753A395E418072 bash-3.2# cd / bash-3.2# bless --info . finderinfo[0]: 803839 => Blessed System Folder is /System/Library/CoreServices finderinfo[1]: 846201 => Blessed System File is /System/Library/CoreServices/boot.efi finderinfo[2]: 0 => Open-folder linked list empty finderinfo[3]: 0 => No alternate OS blessed file/folder finderinfo[4]: 0 => Unused field unset finderinfo[5]: 803839 => OS X blessed folder is /System/Library/CoreServices 64-bit VSDB volume id: 0x82BCF4CF22760DAE bash-3.2# The bless information on my USB stick looks similar to what I see on my hard drive. I used to be able to do this. I am no longer able to boot off of a USB stick. I am no longer able to boot from my recovery mode partition. Help? How do I make this work, or has Apple done something to the firmware and this will not work at all anymore? /Volumes/EFI/EFI/APPLE/FIRMWARE/MBP112_0138_B25_LOCKED.scap has a date of 2017-09-26 And for completeness, bash-3.2# bless --info /Volumes/Recovery\ HD/ finderinfo[0]: 24 => Blessed System Folder is /Volumes/Recovery HD/com.apple.recovery.boot finderinfo[1]: 25 => Blessed System File is /Volumes/Recovery HD/com.apple.recovery.boot/boot.efi finderinfo[2]: 0 => Open-folder linked list empty finderinfo[3]: 24 => Alternate OS blessed file/folder is /Volumes/Recovery HD/com.apple.recovery.boot finderinfo[4]: 0 => Unused field unset finderinfo[5]: 24 => OS X blessed folder is /Volumes/Recovery HD/com.apple.recovery.boot 64-bit VSDB volume id: 0xE93483E4DDDE9594 And something I just thought of in case it makes a difference: on the USB stick, bash-3.2# bless --info /Volumes/Recovery\ HD/ finderinfo[0]: 23 => Blessed System Folder is /Volumes/Recovery HD/com.apple.recovery.boot finderinfo[1]: 24 => Blessed System File is /Volumes/Recovery HD/com.apple.recovery.boot/boot.efi finderinfo[2]: 0 => Open-folder linked list empty finderinfo[3]: 23 => Alternate OS blessed file/folder is /Volumes/Recovery HD/com.apple.recovery.boot finderinfo[4]: 0 => Unused field unset finderinfo[5]: 23 => OS X blessed folder is /Volumes/Recovery HD/com.apple.recovery.boot 64-bit VSDB volume id: 0x00D7DD48B1E38F6A bash-3.2# ls /Volumes/EFI/ total 6 1 .Spotlight-V100/ 1 .Trashes/ 4 ._.Trashes* 1 .fseventsd/ --- Entertaining minecraft videos http://YouTube.com/keybounce _______________________________________________ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
