Issue Description

I've setup this machine originally using https://github.com/al3xtjames/Gigabyte-GA-Z77X-macOS-Install

Everything has been working fine for months. Suddenly (no updates or anything) the audio stops working so I re-run the installation script:

./GA-Z77X.sh --update

No changes, so I try re-installing:

./GA-Z77X.sh --install

From this point, I can't boot anymore. The booting process seems to take more time than usual (the apple with the progress bar), then when it should show the desktop (the progress bar finishes) it shows only a black screen.

I attach a quick picture booting with verbose mode: poblemo

After this, the verbose log tells something about timeouts and AppleACPICPU

Also I can't boot from the Recovery HD, seems that it crashes/freezes at some point (kind of issue with the graphics?) and it autorestarts. The Recovery HD was working fine previously

How could I roll back or do something to reach my desktop?? Thanks in advance for any suggestions.
