The bless command sets volume bootability and startup disk options. In some circumstances these may be altered by volume manipulations and require resetting. It can make the difference in a volume being bootable or not.

With the introduction of El Capitan, Apple introduced an enhanced system security mechanism dubbed System Integrity Protection which effectively locked down certain system directories from unauthorized changes; not even the root account is allowed to make changes to the contents of those directories. Disabling SIP (which officially cannot be accomplished from a running system, ie. it must be done from the Recovery platform) affords the system security level of Yosemite. SIP is the reason that Pike R. Alpha had to develop an entirely new boot.efi for El Capitan, and why the PikeYosFix script that shielded users from system software update changes that reverted back to the original boot.efi, no longer works.

Has anyone upgraded a previous Yosemite install to El Capitan? I remember I installed Yosemite that way, upgrading from the previous install by replacing the boot file on the installer. Is it doable now?

Type man bless in Terminal to get a rundown on how to use the bless command.

Type csrutil in the Terminal app of the Recovery OS to get a rundown on how to disable, enable, and check the status of SIP.

Anyone else not able to boot into Recovery?

I've tried holding command+R while booting as well as choosing it from the boot options menu. Just boots the main partition.

I too am having an issue booting to the Recovery Partition as well. It worked for me a bunch of times in the past 3 weeks since I put El Cap on my 1.1

The only thing I change on my system was to add the Inateck USB 3 card people had recommended in this and some other threads. The only thing I really found the card to mess with was my ability to login to iTunes or the Mac App Store. I ran a few terminal commands to delete my user info and then it let me sign in. I pulled the card and tried again but that did not seem to be the reason it wasn't going to recovery mode.

I used http://musings.silvertooth.us/2014/07/recovery-partition-creator-3-8/ to create a new recovery partition on a different drive and after that I was able to boot to it with Command+R *
I have Lion on the drive as well and only drop it in one of the internal bays if I really need to boot to something else or boot to the recovery partition to replace the boot file.

*Your milage may vary :)

so I was just able to fix it--

in Terminal-

$> diskutil list

note there should be /dev/disk0 with partition 3 being Recovery HD

$> diskutil mount /dev/disk0s3

you'll now have Recovery HD. browse to com.apple.recovery.boot and you should see boot.efi

unlock the file

$> sudo chflags nouchg /Volumes/Recovery\ HD/com.apple.recovery.boot/boot.efi

replace it with the one you use from https://github.com/Piker-Alpha/macosxbootloader

(I just copy + paste in Finder)

then lock the file and unmount

$> sudo chflags uchg /Volumes/Recovery\ HD/com.apple.recovery.boot/boot.efi
$> diskutil unmount /dev/disk0s3

this allowed me to finally boot into Recovery so I could disable SIP w/ the following

$> csrutil disable

:)

Apologies if this is a question which has been addressed earlier (though a thorough search here and Google is not yielding any answers) - is there a way to disable the hardware/ID check which prevents the App Store from allowing downloading of El Capitan please? I don't have access to another Mac.

I'm using a Mac Pro 1,1 running Yosemite. I am aware of the 'Mavericks Download Enabler' - but that's very old now.

Alternatively how can the ftk3252456602304584541.pkg (which Apple do allow to be downloaded) be opened? XAR is failing me, as is Pacifist.

Anyone knows if this GRAPHIC CARD: Ati Radeon R7 240 2GB ddr3, works ok on MAC PRO 1.1 ? I have the GeForce 210 right now.
Thanks.

Hi, I have installed El Capitan on MacPro 2.1 on two different drives SSD and HD. Booting normally but computer reboot after 2-5 minutes. Same thing on SSD or HD. Any idea? Do it's my copy of El Capitan installer is "freaky" ?
