  1. 1. Did this work for you?

    • It fixed my issue on an Intel
    • It fixed my issue on an AMD
    • It didn't do anything on an Intel, everything's the same.
    • It didn't do anything on an AMD, everything's the same.
    • It broke my installation.

This is really quick, simple and to the point. If you have a 30 second boot delay saying "Couldn't set up Diskarb sessions" then this is for you. Simply download the attached file, unzip it and put these kexts in /system/library/extensions/. you'll need an admin password. Then, delete extensions.kextcache and extensions.mkext and repair permissions.


NOTE: I will say this once and only once. I've tested this on my system, specs are in my sig. DO THIS AT YOUR OWN RISK!!! You stand a chance of not being able to boot again. Please, do this in a cautionary method. BACKUP YOUR PREVIOUS VERSIONS OF THE KEXTS. This is untested on AMD, I have no clue if it will work. The kernel I tested it on is Semthex 8.8.1, from the JaS 10.4.8 install. If anybody with an AMD feels like testing, feel free, but remember it's risky.


OH and, boba899 gave me the idea.
