How about multibeast users? Is that the same process , Or there's other way to update?
If you follow tonymacx86's and my procedures in posts #1 and #2, you will only need to run toleda's updated audio driver script which is located in his
sticky thread in the Sierra Desktop Support forum section. However, make sure you're running an acceptable System Definition as a lot of older Macs are not supported in Sierra. Use an iMac14,2 system definition which you can change in El Capitan using MultiBeast v8.2.3 by
just changing the System Definition to iMac14,2.
UniBeast and MultiBeast for Sierra will be out shortly. There were problems with Clover that kept Sierra running properly or both the "Beasts" would have been out by now. So, if you're not in a hurry (and I wouldn't be), wait a couple of days for the "Beasts".
