Please note: The macOS Sierra 10.12.4 update requires Clover_v2.3k_r3994 or newer. Otherwise kext injection doesn't work and you may get issues with sound, graphics, etc. A good way to get around this is to always install extra kexts to /Library/Extensions/, as MultiBeast does. Otherwise update Clover. We'll be updating MultiBeast soon to make this easier, until then feel free to use these Clover packages we've prepared for MultiBeast. 2017-03-30 22:20 GMT: Uploaded corrected Legacy Mode install package.
