Hi all, I installed High Sierra last night on my PC build. It went mostly well but I couldnt get my GPU working and the audio (external audio device - Apogee One) doesn't seem to be working correctly. I am getting glitchy, scratchy interference noises. As I am building the PC for audio recording, obviously this is now use. Has anyone else had a similar issue? Is there a fix?

Hi everyone, I've been following the install guide and it led me to this step. Here's my send me file I'm a total noob. Thanks for your help! Send me Grahams-iMac.zip
