    10.12.6 (or Clover update) won't complete boot

    My machine ran from roughly 2016 to October 2019 continuously with no problems. Then I upgraded from macOS 10.12.4 or something to 10.12.6 and also upgrade Clover and it stopped booting. I had upgraded 10.12 several times before and only needed to update my Nvidia web driver, and also upgraded...

    AMD GPU clock and fan control

    I have an AMD RX580 and it started off working as expected for about two weeks. Then after a necessary reboot, the performance seems to have dropped by about 40%. Subsequent reboots haven't brought it back. Right now it's performing the same as my old R9 280X for the same tasks (I am using...

    Black Screen, NVIDIA & AMD. Booting?

    My i7-5820k used to run with an NVIDIA GTX960 and an AMD R9 280X on macOS Sierra 10.12.6, up until I attempted to exchange the R9 280X with an AMD RX580. First I updated Clover to the latest version to meet the minimum Clover requirements in the AMD guide...

    Screen Goes Black During Use

    I searched the forums and there's a known issue with a black screen during boot, but that's not what's happening to mine. I have an i7-5820k with an NVIDIA GTX 960 and an ATI R9 280X running macOS Sierra. Both are computing OpenCL. Everything has run fine for months, but recently on rare...

    Will two different types of video cards cause conflicts? I have currently have an NVIDIA GTX 960, and have two more PCIe16 slots open. I want to fill one of those slots with a Radeon RX 470. I'm not going to try to bind them together with SLI or anything like that. Both of them will be doing...

    Prohibited Symbol (couldn't allocate runtime area) error on installation

    I'm trying to install Mac OS Sierra from scratch on the system in my profile (AsRock x99 Extreme4, i7-5820k, NVIDIA GTX960) using the new Unibeast 7.01. Looking at the parameters in the Clover menu, it looks like it recognizes everything correctly. But when I boot, I almost immediately get the...

    I've been trying to install Yosemite on an HP 2570p laptop using the latest version of Unibeast and keep running into the circle/slash symbol about halfway into the boot process after hitting go on the Clover menu. Apple's website says this the "prohibitory symbol" and says it indicates the...
