10.) Some Terminal Work

Now it's time for some work in the terminal. Don't be affraid, it's quite easy. The goal of this steps is to cleanup the USB-Stick, set the owner and permissions for kernel extensions and to build the kernel extensions cache file.
Login into an account with Administrator rights
Insert the EFIBOOT USB-Stick
Open the Terminal Application (Applications -> Utilities)
Become root with by entering "sudo -s" and providing your administrator account password

If you insert a removeable drive like an USB-Stick it gets mounted by Mac OS X with some options we don't want, like nosuid or noowners. Therefore we have to remount the USB-Stick without this special flags. Ok let's start

root@MacBook [~] > mount
/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local)
fdesc on /dev (fdesc, union)
map -hosts on /net (autofs, automounted)
map auto_home on /home (autofs, automounted)
/dev/disk0s3 on /Volumes/BOOTCAMP (ntfs, local, read-only, noowners)
/dev/disk1s2 on /Users/hhallas (hfs, local, nodev, nosuid, journaled)
/dev/disk2s1 on /Volumes/EFIBOOT (hfs, local, nodev, nosuid, journaled, noowners)

Some background info about Unix Devices. Under Unix devices can be accessed through special device files. You can find these device files normally in the directory /dev. Harddisks and also USB-Stick are named /dev/disk or /dev/rdisk. The first number is the disk counter. Then comes an "s" (stands for slice/partition) and another number, which is the partition number. You can see that the USB-Stick is the device /dev/disk2 and /dev/disk2s1 is the EFIBOOT partition on the USB-Stick. You can find this info also in the Disk Utility. Select the disk or partition and then "Info". Disk Identifier is the same as the device name under /dev. OK, now let's unmount and remount the USB-Stick. Find out which disk number has the USB-Stick in your case. In my case it is the number 2.
root@MacBook-Pro [~] > umount -f /Volumes/EFIBOOT
root@MacBook [~] > mkdir efitemp
root@MacBook [~] > mount_hfs /dev/disk2s1 efitemp/
root@MacBook [~] > mount
/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local)
fdesc on /dev (fdesc, union)
map -hosts on /net (autofs, automounted)
map auto_home on /home (autofs, automounted)
/dev/disk0s3 on /Volumes/BOOTCAMP (ntfs, local, read-only, noowners)
/dev/disk1s2 on /Users/hhallas (hfs, local, nodev, nosuid, journaled)
/dev/disk2s1 on /Users/hhallas/efitemp (hfs, local, journaled)

The USB-Stick is mounted now at the directory efitemp (which was created by mkdir efitemp) and without these special option (nosuid, noowner). Let's start with some cleanups.
> cd efitemp
root@MacBook [~/efitemp] > ls -la@
total 6336
drwxrwxr-x 17 root wheel 646 Jun 28 21:56 .
drwx------+ 35 hhallas staff 1258 Jun 28 23:31 ..

drwxr-xr-x 4 root wheel 136 Apr 1 16:17 usr

The command "ls -la@" lists all the file and directories and also the extended attributes. We will now delete all these extended attributes (with xattr) and the .DS_Store files.
root@MacBook-Pro [~/efitemp] > find . -type d -exec xattr -d "com.apple.FinderInfo" {} \; -print
root@MacBook [~/efitemp] > find . -type f -exec xattr -d "com.apple.FinderInfo" {} \; -print
root@MacBook [~/efitemp] > find . -type d -exec xattr -d "com.apple. quarantine" {} \; -print
root@MacBook [~/efitemp] > find . -type f -exec xattr -d "com.apple. quarantine" {} \; -print
root@MacBook [~/efitemp] > find . -name ".DS_Store" -exec rm -f {} \; -print

Now let's set the ownership and permissions of the kernel extensions and build the kernel extensions cache file extensions.mkext.

root@MacBook [~/efitemp] > cd Extra/
root@MacBook [~/efitemp/Extra] > chmod -R 755 Extensions
root@MacBook [~/efitemp/Extra] > chown -R root:wheel Extensions
root@MacBook [~/efitemp/Extra] > kextcache -a i386 -m Extensions.mkext Extensions
root@MacBook [~/efitemp/Extra] > ls -la@
total 112
drwxrwxr-x 6 root wheel 204 Jun 28 23:58 .
drwxrwxr-x 16 root wheel 612 Jun 28 23:45 ..
drwxrwxr-x 6 root wheel 204 Jun 28 23:45 Extensions
-rw-r--r-- 1 root wheel 52374 Jun 28 23:45 Extensions.mkext
drwxrwxr-x 6 root wheel 204 Jun 26 10:52 Themes
root@MacBook [~/efitemp/Extra] > cd
root@MacBook [~] > umount -f efitemp
root@MacBook [~] > rmdir efitemp


That's all. You are done and almost ready for the first boot of your Chameleon-Mac.

ok, hab mich nun ein bisschen in unix herreingelesen und glaub ich hab jetzt das meiste verstanden.



es sollte doch reichen wenn ich diese befehle nacheinander ins terminal eingebe:




ist das so weit richtig ?
bin mir nicht sicher ob z.b. die zeile "> cd efitemp" so stimmt
kanns leider noch nicht selber testen, da mein OS X noch nicht da ist.
