Is there a way to upgrade OS to Sierra? I tried the direct upgrade but when I reboot and then try to perform the step with spacebar and boot without kextcache the option is not there and i boot using -v. witch then gets to the system uptime line and then reboots the system with no errors to the clover boot screen. Also when i try to boot using the USB Sierra installer and chaos -v. I get to the same place System Uptime XXXXX nano then system reboots to clover screen. I have attached the requested files for your review.
