Hello
@Z390HTosh,
To answer your questions:
- We can (and should) switch to OpenCore from Clover. There's a guide here. It's really critical to follow each step carefully and double-check each step. A full backup of Mojave should be made in advance.
- In OpenCore, we should set SecureBootModel to Disabled. Once you have configured the OpenCore EFI, just let us know if you have any "preflight" questions.
- Once you're on OpenCore, it's a simple matter to upgrade from Mojave directly to either Big Sur or Monterey. Upgrading to Monterey will be easier because it's just a matter of going to System Preferences --> Software Updateand letting it do all the work.
- Upgrading to Big Sur will require you to download the full Big Sur installer, then double-click to launch.
Hi
@CaseySJ, (
Fixed) I created the USB flash drive with the edited Config.plist (I am using Intel iGPU). When I try to boot from the USB drive, the system just reboots just after selecting my Mojave Disk. Don't know what went wrong. If I choose to again boot from the USB drive, a message appears saying: OC : Failed to Drop ACPI. Then straight away it boots to recovery.
PS : My Mojave is booting normally from SSD
Fixed: it was my mistake. Once I set the SecureBootModel to Disabled, it booted normaly....but sometimes it shows Failed to Drop ACPI, and then boots to recovery without showing any partitions.
Update: I have swapped the EFI of my Mojave SSD and USB disk.
Also I am using iGPU. Do I need to do anything else to make it run stable?
Update: After booting, just when the login screen comes, suddenly the screen goes off with a pop sound. When I press a key it will come back on, this happens randomly only at the login screen. I don't know why that's happening?
I am planning to Upgrade to Big Sur. I already have a bootable backup of Mojave with Clover. Now I iam in OpenCore. So, inorder to make a backup now, should I just Run the Carbon Copy Cloner script just like that, or make any changes to the script and do?
