Help change theme opencore

[Montelli]

Greetings,

 

I updated opencore from version 1.0.1 to the latest version 1.0.4 and strangely the theme disappeared. Now when I start the bootloader I get this screen , 

 

How can I set theme?

 

thank you in advance for reply 🙂

I updated via OCAT, mounted EFI partition, loaded config.plist and then clicked on Upgrade opencore and kext.

 

So I think I updated confi.plist, right?

 

Excuse me, but what is this OcBinaryData for?

 

Thanks

It is a folder that contains preferably the latest Drivers, Boot Menu GUI oppose to just Text to choose from.

Also Audio files i.e Boot-up Chime as well as Font etc, etc.

 

If you expand and peruse the Folder, you will see all the files within.

So in essence whenever you update the EFI Folder with OCAT, this is also checked and updated if an update is warranted.

 

Ok thanks for the reply,

But I think I updated and synchronized to latest version via OCAT from this panel, right?

 

 

Now to get themes, what should I copy from this OcBinaryData folder?

You don't have to copy anything OCAT will update the necessary files for you as long as the Resources Folder is present in EFI/OC. Just insure this box is ticked in this section in OCAT (as shown).

 

Another thing to point out, in the config.plist open with OCAT and in Misc/Boot/PickerVariant box, you must enter the name of the Theme you want to use, just type Acidanthera in the space as shown then save and you're done.

ok pickervariant was on Auto and now i put acidanthera\syrah. I rebooted but there is no theme.. why ?

If you're still having a problem, remove your personal data from the config.plist

Zip and post the EFI Folder here and we will make the necessary changes for you.

 

Ok, thanks, changing PickerAttributes to 144 worked.

 

Now theme is applied, but where can I find other themes to customize it further?

 

Also, how can I disable automatic startup at boot? It starts automatically on Windows unless I manually stop it moving cursor.

 

Thanks!

(Ctrl+Enter.)    Which disk do you want to start from? Until NVRam Reset

Insure you have the macOS Disk as the default disk to boot from, the first Disk the machine sees, in other words you need to change the Boot order if it automatically starts on Windows.

This is done in the BIOS of the P/C.

 

Congrats you're making good progress. 

 

 

Sorry, I think I didn’t explain myself clearly. When I start the computer, I see this screen,

but if I don’t move icons using arrow keys, the system automatically boots into the first icon, which is Windows...

I just want to disable the boot timer. Where can I disable it in OCAT? 

Thanks!

Misc > Boot > Timeout= 0

 

In your spare time, take a look at the Opencore documentation 😉
