I can't tell much from the photo you posted. However, I do see that you have a Synaptics trackpad and you have been trying to load the elan i2c kext. I'm thinking that you just need to use the VoodooI2C.kext and the VoodooPS2Controller.kext with no other I2C kexts and no SSDT for TPL0. Also, make sure that both kexts are the most recent so that you don't have any conflict with the VoodooInput.kext that is a plug-in for both of the other Voodoo kexts.

Montblanc Posted July 29, 2020 Share Posted July 29, 2020 @eSaF I've now tried Chris1111's Wireless-USB-Big-Sur-Adapter on both machines and it gets rid of Preboot and reverts to the correct name. No Startup disk showing though on either Hacks, or real Macs iMac 13,2 or Macbook Pro 2017. So that looks really broken in beta3!

Loloflat6 Posted July 29, 2020 Share Posted July 29, 2020 (edited) I updated Big Sur Beta 2 —————> Big Sur Beta 3 on my X299 Gigabyte UD4 System ( Finaly ) The installation process went smoothly in four stage. No improvement or other bug as reported here and in comparison on my AMD X570 system. I used the same EFI OC 6.0.0 as for Beta 2. Now a humorous thing : In France, here in Chartreuse we also have our Big Sur named Grande Sure Look : Spoiler Edited July 29, 2020 by Loloflat6 1 3 Link to comment https://www.insanelymac.com/forum/topic/344428-pre-release-macos-big-sur/page/62/#findComment-2732466 Share on other sites More sharing options...
devillived666 Posted July 29, 2020 Share Posted July 29, 2020 Hi guys. I successfully installed beta 3 from usb. I just finally got my dw 1560 wifi using oc latest along with latest kexts. The odd thing is using airportbrcmfixup makes my keyboard stop working. Ive got a S405UA-EB906T: Intel Core i5 7200U Intel HD Graphics 620 8gb DDR4 Elan touchpad conexant 8150 Not sure i need to include efi folder or not? Without the airportbrcmfixup kext, keyboard works but wifi icon is grey and just says 'trun on' under settings but cant change anything.

SavageAUS Posted July 29, 2020 Share Posted July 29, 2020 Oh ok!!! - On a negative note, I must say I am happy to hear the no Startup Disk is also a bug on real Macs, thanks for the post. I forgot to add my disk is now showing up at the Boot Menu as I named it - 'macOS Big Sur' - after a few reboots.My disk is still named Preboot I’ve rebooted and restarted numerous times. Beta 4 should be out soon and hopefully that will rectify it.
