Guide for RAID-0 on OS X 10.8.5 using tonymacx86 tool set

[Going Bald]

I want to try this, i have 1 question, does it effect TRIM. thanks you.

AFAIK, TRIM does not work in RAID. Considering that TRIM for non-Apple SSDs does not work without modifying the kext plugins, which invalidates the signing of the kext, which causes Yosemite not to boot - gives a circle/slash on the boot screen unless you turn off signing - which gets turned back on at the next update, I have to wonder why you care.

For non-Apple SSDs installed non-RAID, most have garbage collection in the firmware - all you need to do is give the drive a bit of idle time to take care of the matter before sleep occurs. I have changed my delay time to 15 minutes on display sleep and 45 minutes on system sleep. Since I have a Crucial M500 in the MBP, it seemed the logical thing to do. This seems, so far, to be working well and is recommended by crucial for their SSDs.

Works like a charm! unfortunately i took me a couple of days to realize that i used | instead of \ when i was in the terminal. my advice for anyone would be to copy and paste just change the disk name.

Running Mavericks 10.9.5
Installed a pair of 256GB XP941 drives on a dual drive PCIe pass thru card - it takes 2 PCIe slots, but I had a spare anyway.
Only thing I had a problem with was the line

cp -R Extra /Volumes/Boot\ OS\ X/

no such file - I needed to use

cp -R /Extra /Volumes/Boot\ OS\ X/

other than that, worked like a charm. Talk about crazy fast!! see BlackMagic results!

Yes you would get that error message if you were not in the same directory as the Extra folder. In the guide, I encourage people to move all the files to the desktop and run the terminal session from the desktop.

And I think that you have set a new standard for "crazy fast"!!!

Good modding,

Yeah, I went back and read the instructions again - I failed to copy the /Extra folder to desktop. Had I done so I would not have gotten the error message.

Don't know about a standard, but that is faster than anything I have ever seen with Black Magic for sure!

I followed these instructions to a T on my GA-Z77M-D3H-MVP. I can boot fine from Unibeast thumb to the Apple RAID and everything is working great after Multibeast DSDT Free but when I boot direct without thumb I get black screen:

boot0: GPT
boot0: test
boot0: test
boot0: test
boot0: test
boot0: <bunch of gobbledygook here>

Thoughts?

I think this might work

#!/bin/bash

for mydisk in `diskutil list | grep 'Apple_Boot Boot OS X' | awk -F " " '{print $8}'`; do
    rmydisk=${mydisk:0:5}
    fdisk -f boot0 -u -y /dev/r$rmydisk
    dd if=boot1h of=/dev/r$mydisk

    diskutil mount $mydisk
    cp boot /Volumes/Boot\ OS\ X/
    cp -R /Extra /Volumes/Boot\ OS\ X/
    diskutil unmount $mydisk
done

Thanks a lot for that script. I extended it slightly by automating the Chimera.pkg extraction step. You just have to pass path to Multibeast app as first parameter to script and rest should work automatilcally.

#!/bin/bash

if [ -z "$1" ]; then
  echo "ERROR: Multibeast missing."
  echo "FORMAT: $0 <Multibeast App>"
  exit 1
fi

TEMPDIR=$(mktemp -d ./tmp.chimera.XXXXXX)
BOOT="$TEMPDIR"/usr/standalone/i386/boot
BOOT1H="$TEMPDIR"/usr/standalone/i386/boot1h
BOOT0="$TEMPDIR"/usr/standalone/i386/boot0

# use echo for debugging
PRECMD="sudo"

xar -xf "$1/Contents/Resources/"Chimera*.pkg -C "$TEMPDIR"
tar xzvf "$TEMPDIR"/Payload -C "$TEMPDIR"

for mydisk in `diskutil list | grep 'Apple_Boot Boot OS X' | awk -F " " '{print $8}'`; do
    echo "== DISK $mydisk =="
    rmydisk=${mydisk:0:5}
    $PRECMD fdisk -f "$BOOT0" -u -y /dev/r$rmydisk || { echo "ERROR: Could not mount disk r$rmydisk"; exit 1; }
    $PRECMD dd if=$BOOT1H of=/dev/r$mydisk || { echo "ERROR: Could not upodate boot sector"; exit 1; }

    $PRECMD diskutil mount $mydisk  || { echo "ERROR: Could not mount disk $rmydisk"; exit 1; }
    $PRECMD cp "$BOOT" "/Volumes/Boot OS X/"  || { echo "ERROR: Could not copy file $BOOT"; exit 1; }
    $PRECMD cp -R /Extra "/Volumes/Boot OS X/"  || { echo "ERROR: Could not copy directory /Extra"; exit 1; }
    $PRECMD diskutil unmount $mydisk  || { echo "ERROR: Could not unmount disk $rmydisk"; exit 1; }
done

rm -r "$TEMPDIR"

Please ignore....cd Desktop was the answer.... thanks

Hi!

I am having an issue with fdisk command as following. Please let me know what my issue could be.
thanks in advance.

Hi, thx for your time.

But i cant boot from the Raid, just only when i put my USB stick inside and boot from there.

Its my first Build so any Help is welcome.

Thx

Hey can I raid 0 the SSD and put Mac and Windows OS in it?
