Thanks for your answers, i found a way easier way to do it if you have windows running on the same machine also:
1) You dont need to install paragon HFS, just mount efi partition of disk, which is FAT32, unlike system itself...
1.1)run/open diskpart as admin (either from start or from cmd, or from windows(or system32) folder
1.2) In diskpart - list disk, then select disk X(use correct number)
1.3) In diskpart - list partition, then select partition X (correct number)
1.4) In diskpart - assign letter=x
1.5) Efi is now mounted, but explorer wont allow you open it(stupid windows rights). Open notepad AS ADMIN, File ->open ->navigate to efi/clover/kexts (yes, this will trick windows rights, lol)
1.6) Paste kext files (still in notepad open window)
The issue was that after the update it did not recognise the USB ports so nothing worked (keyboard / mouse), following the above steps i mounted the EFI and placed
USBinjectall.kext into efi/clover/kexts/other
Rebooted the computer and the usb worked, so now i could use the keyboard and mouse and complete my set up.
Everything is now working apart from sound, but ill find a way to fix that as i have done before.
Can a moderator change the title to something more specific like "Installing Kext on clover EFI - USB not working after High Sierra Upgrade" thanks.
Just a note:
i did this in order to get FCPX 3D text working as on sierra it didnt, i installed the updated Web Drivers by NVIDIA and now everything is working perfectly.
for anyone wondering my set up is:
Intel Core i7-6700 Skylake
Asus H110M-A/M.2 Motherboard
NVIDIA GeForce GTX 1060 6GB
16GB DDR4 2133MHz
250GB SK hynix SL301 SSD (Windows)
Seagate 1TB BarraCuda (Extra Storage)
Samsung 850 EVO 1TB (OSX)Go to the full post
