I then typed 'cd 108' to change directory so that I can get the audio patch for Mountain Lion 10.8 and that would appear to be what I'm meant to type but I only get either 'command not found' (if I type 'cd108'), or 'No such file or directory' if I type 'cd 108' . The Read Me for the patch has this in it and I guess it's my fault for not being able to folow what it means:
In a nutshell, you have to run a script named PatchALC892.sh in the 108 folder (to patch 10.8.x osx audio), in the PatchALC892 folder at the root of your system disk.
First copy the PatchALC892 folder to the root of your drive (same level than /System, /Users, /Volumes,)
Under Terminal as root user, go to the script folder:
your host$: sudo -s
bash-3.2# cd /PatchALC892/108
then run the script:
You can use line completion and just type
then use tab key to complete the name of the script, then return or enter.
Using ./ indicates that the file is in the current folder, standard unix shell:
. = current folder
.. = parent folder
/ = root of the drive
