i've been on Yosemite for a long time. i have a SandyBridge i7 and a 6-series chipset Asus Z868V Pro Gen3 board. it has served me well. Clover version 3320 works for me. the MoBo is UEFI w/upgraded BIOS, but it boots only with Legacy Clover, never UEFI. strange but that's been okay with me. everything's worked for me...i use no DSDT, have an AMD Radeon HD6870 gfx card, and the board has Intel NIC and ALC892 audio. I created a SSDT using revogirl's old script. It has worked fine for me too. the only issues i've had over the years have to do with USB. if I have a bunch of hubs and drives connected (which I do), sometimes the hubs and connected drives stop working. recently i decided I wanted to upgrade my OS, since some of the software i use now requires 10.12+. I tried your tools to grab the High Sierra image and burn to flash drive. but when I booted up off the flash drive, it never got past the "waiting for Apple Key Store" line. so I quit. next, as a test I used tmx86's tools to install sierra on another drive, as well as a newer version of clover, but for some reason, even though the install was successful and I was able to migrate my current content over, when I try to boot off that Sierra drive with the newer version clover it won't do it. no matter what I try, even though the clover "6" digit flashes for a moment, it reverts to the current clover version 3320 off my other drive. thus, none of the configurations specific to the sierra drive are being loaded, so even though i can still use that sierra system, it's not fully working. NIC is okay but the ALC892 audio doesn't work and i get that never-ending USB overcurrent error message. i don't mind wiping out that tmx86 Sierra install and, if you can help me, using your tools to load a (hopefully) flawless-working Mojave on that drive. if you can help me do it I'll be happy to compensate you for your time & expertise. let me know if you can & if so, how I might proceed. thx in advance.
