I have attempted to install the os on my 2008 mbp. Following the ubuntu interactions, I copied the os to usb, partitioned the ssd on the mac, did not format the new second partition and then installed reFIt and rebooted on choosing the the windows/fat option, the stayed on a screen showing only the following information ACPI PCC PROBE FAILED sdb no caching mode page found

and then nothing.

tried the google-fu but no ideas, any assistance?

just did a DDG search on "ACPI PCC PROBE FAILED" and found this page http://yeites.blogspot.com/2015/05/acpi-pcc-probe-failed-starting-version_29.html

From this ... it appears that there could be an SCPI issue ... I dont remember how to do this on a macbook ... but try turning it off and then see if it works

caveat -- apparently you cannot put to sleep after doing this

  • Thanks for the reply. Gave up installing on MacBook Pro. And installed on a Lenovo. Working grand. Nice os Commented Feb 8, 2016 at 8:41
