Hello, I tried a clean install yesterday. I created a bootable USB stick with Unibeast 7.0.1 and the latest version of Sierra downloaded yesterday from the App Store. The processus worked but when I tried to boot with it, it didn't work. Actually there was an infinite Apple loading. So what I did is created a bootable USB stick with an older version of Sierra (10.12.0) with Unibeast 7.0.1, boot on it (worked perfectly this time). After the install was complete, I updated my system to 10.12.4 with the App Store. All runs perfectly fine now. So I create this thread just to WARNING YOU about this: DO NOT CLEAN INSTALL YOUR SYSTEM BECAUSE UNIBEAST 7.0.1 DOES NOT WORK WITH SIERRA 10.12.4 Hope the team will read this thread and update Unibeast.
