    No. You can boot into safe mode (-x) and replace the kexts from there

    @MacPeet
     
    Thanks for your help! I followed your instructions and now I have Audio with the AppleALC method, though LayoutID 13 enables only the front headphone jack output and not the rear Line Out, where I have my speakers connected. Thus, I reverted back to LayoutID 11.
     
    The two problems I'm currently facing are the following:
     * The login screen that is shown upon boot is red, instead of the blurry background desktop image of the last logged in user
     * Most importantly though, my Optiplex goes to sleep, but when I wake it up the display is completely dark. Anyone else facing this problem?
     
    I have uploaded my EFI folder here: http://ul.to/jz1lelko
     
    FYI, my setup:
     * Optiplex 780
     * CPU: Intel Core 2 Quad Q9550@2.83
     * RAM: 16Gb
     * Graphichs: ATI Radeon HD5450@1Gb
     * Clover Release: r4220 (latest)
     
    Regarding NightShiftUnlocker, I placed it in Clover/kexts/10.13 and it works just fine 
     
    Finally, when the upgrade finished, I had to boot from my unmodified, existing installation of Sierra (I cloned my sierra installation to a different internal hard drive and I upgraded from there, to play it safe) and replace the HD5450 rollback drivers, as the screen was black. That means that I need a spare working Hackintosh installation every time a High Sierra update is released so that I can replace my graphics drivers?
     
    Thanks for all your help

    Some news:
    Without Injector iGPU many AMD graphics cards no longer work with HighSierra.   However I have made a rollback of Sierra with following Kext's and the Optiplex780 works:   AMDRadeonX3000.kext
    AMDRadeonX3000GLDriver.bundle
    IOAccelerator2D.plugin
    IOAcceleratorFamily2.kext
      Unfortunately of course not update safe.   Audio works with flags -alcbeta -lilubeta and HDMI audio works as always with Shrike.

    I'm glad to report that the Combo Updater for 10.9.2 works flawlessly (almost). I had to edit the plist files of the graphics drivers (AMD5000Controller.kext and AMDRadeonX3000.kext) as per instructions, which was kind of expected, but other than that I didn't face any issues so far.
     
    Just one side effect: My Optiplex does not wake from sleep when pressing a key from the keyboard or moving the mouse anymore, i.e. does not wake from usb inputs. Personally, I don't care that much since it wakes by pressing the power button. If anything else rises, I'll keep you posted!!!

    Tried it myself today. Works like a charm!
     
    If only I could find a driver for a rather old Panasonic Workio MFP we have at the office, which is our main printer, I would completely format my Windows installation  . But you're right. It boots in seconds (under a minute), and it shuts down / sleeps almost instantly! The Windows 7 installation I was talking about, although quite fresh (I have it a couple of days), and with the most basic programs we need at the office, just takes ages to become responsive after booting / waking up...
