My experience has been the opposite!
I've got it disabled and was able to update to that latest version of Big Sur!
I might try to enable it now the systems running to see if I can still boot 🤔
How bizarre.. mine crashes as soon as osx starts to load if I don't disable secureboot, just goes to show that two machines on the same motherboard can behave very differently 🤔
Is secureboot important?
No problem re the sleep issue, it's not important, I've just set the computer up so that it doesn't go to sleep.. 👍
I'll make a time machine backup to an external drive, I'm guessing I can do this by booting up the installer USB and loading time machine from there?
Thanks Moozuki
But I'm actually up and running using your earlier EFI, other than wake from sleep everything else seems to be working.
I even managed to upgrade to the latest version of Big Sur.
I'm not sure why the install process itself was such a big issue, it was weird, having to...
Thanks Edhawk
I'll test your revised efi.. thanks for this.
But as a quick update, I managed to get through the installer by setting the secureboot setting to "disabled", but should I be worried about leaving it on this setting?
Also, the computer completely freezes when it goes to sleep...
I posted my EFI folder a couple of posts back, I haven't changed it since then 👍
Although, I'm trying a different secureboot setting at the moment, it was set to default.. I've just changed it to j137 and am going through the install process again at the moment 😎
Another update on this.. so I started from scratch and created a new installer using a different USB stick but using the same EFI folder. This time it worked and i was able to boot to the installer.
I can then use disk utility to format my SSD
drive and start the Big Sur install process, all...
Hi Edhawk.. my scanpolicy has a number alongside it, I'll set it to 0 and see if this helps.
I've also attached my efi folder, I'd appreciate it if you could take a look at this just incase I've made a daft mistake!! :)
Thanks both..
I've tried a variety of usb ports but this didn't help..
I've also checked in the Drivers folder and can see the HfsPlus.efi file..
Also, when creating the drive I selected Mac OS Extended (Journaled) with a GUID Partition map, is this not correct?
I'm wondering if there's...
Another quick update.. sorry for the delay, I'm in the middle of a house move so things are a bit hectic!
I've created the installer and made all of the changes discussed in this thread (added serials, ROM etc.. commented out device IDs, removed GPU boot argument, changed core count setting)...
Ah ok.. so I can go ahead and comment them out and ethernet / WiFi / nvme should still work.. they just won't show as internal devices, but as long as they work I'm happy 👍😎
Thanks both 👍
I used genSMBIOS from the terminal to generate the serials which I don't believe generated a ROM. As such, should I go ahead and find the mac address of my ethernet port and use that?
Also, I decided to order the same WiFi card as Moozuki, just seemed the easiest option 👍😎
Ok thanks.. now for my next daft question.. how do I disable them? Is there a way to comment them out so that I don't have to delete them completely? 🤔
Am I correct in saying the ROM's the Mac address of my ethernet port? If so, I've got windows 10 installed on the machine so should be able to find the Mac address 👍
Re the device ID for the WiFi card.. thanks for confirming it's not just me who can't find it! Do you think that system will run...
Another quick update on this..
I've removed the boot argument for Moozuki's GPU
I've also generated a serial number, uuid, smb etc and have added these to the config.plist
the only other thing i'm not sure about is removing the reference to Moozuki's wifi card, I couldn't see this in the...
