This MB has an internal USB-C header which is connected to the front case USB-C port.
The MB also has a USB3 header which is connected to the two USB3 ports on the front case.
I'm having power issues with them. I can only use one at a time.
The MB has two USB2 headers, of which I am only using one.
That is connected to the two USB2 ports on the front case.
They seem to work fine.
Replace the one on the CLOVERUSB drive. Check that everything works with the new driver and rename patches etc. removed.
Then if everything is still fine. You can copy the CLOVER folder I provided to the EFI folder on your macOS drive. So it is the default CLover folder and is used to boot your system.
You can then if you want replace the one on your USB installer drive, the one you keep plugged in the back of your system. I would keep the CloverUSB as a further backup, unless you need the USB for something else.
The new Clover folder (Clover3) did not work.
There is a screen flash about halfway through the Apple timeline and then a black screen.
FYI... This flash was present all the time, in every boot scenario, as it is, as I understand, the GPU handoff.
Oddly, it was not present using your Clover2 folder.
The Apple timeline moved smoothly with no screen flash and opened the desktop.
That was the first time I saw the timeline move straight to the end with no stops along the way.
I must have missed something when creating Clover3. I need to compare the two folders to see what I have done to Clover3 to cause this.
As it is none of the changes made to Clover3 were of any real concern, so sticking with Clover2 might turn out to be a better solution. if the boot progress is not distorted and runs smoothly on your system.
Just wanted to circle back here.
I'm using the Clover2 bootloader.
I guess because of all the verbose stuff happening during the boot cycle I mislead you when I said the screen didn't flash during the GPU handoff. It does. It's just not that noticeable.
To change the Verbose boot argument, do the following:
You need to mount the EFI partition on your macOS drive. Use Clover Configurator to select and mount the partition. There is a Mount EFI tab in the left hand navigation list, as highlighted in the screenshot below:
Clover Configurator 'Mount EFI' tab
The screenshot above shows the two drives connected to my system. If I wanted to mount the EFI Partition for either of these drives I would simply select the 'Mount Partition' button to the right of the drive.
Follow these steps to remove the Verbose Mode -v boot argument:
Select the 'mount partition' button for your macOS drive
Enter your password when requested
Select the 'Open Partition' button that is now highlighted
This will open the EFI Partition in a Finder window
The EFI Partition contains your EFI folder. Open this folder
The EFI folder contains these folders on my drive, yours will be similar if not identical.
Open the CLOVER folder.
Your CLOVER folder will be as shown, if you are using a recent version of Clover, it may also contain a drivers64UEFI folder.
Right-click on the config.plist and select 'open with' and select Clover Configurator.
Clover Configurator will open the config.plist, navigate to the Boot tab
In the Arguments window you will see the -v boot argument.
Highlight the -v boot argument and select the '-' (minus sign) near the bottom right-hand corner of the Argument window.
This will permanently remove this boot argument from your config.plist.
Select the 2nd icon from the left below the navigation bar,
This will allow you to Save the config.plist with the change(s) you just made.
Close Clover Configurator.
Close any open Finder windows.
Reboot your system for the config.plist changes to take effect.
You should no longer see the Verbose text when you boot.
Next I'd like to try to fix the resolution, or lack of resolution choices I have.
Now mind you, I'm using an LG TV display as my computer monitor. HDMI from the Radeon card directly into the display.
When in it's native mode (1360 x 768) everything looks fantastic.
I'm attaching 4 screen shots showing the 4 resolutions available so you can see how each one looks.
All I did was click on the different resolutions.
You might be asking yourself... what's the problem using 1360 x 768? Nothing other than when I open various windows or pages, they are so large they take up the whole screen and cannot be resized. So there's a lot of "hiding" windows or pages to see what's underneath them....
