Is Direct Upgrade from El Capitan to Catalina Possible?

[Hack_The_Gibson]

Ok Thanks. Any idea why I can’t make the bootable usb with UniBeast for Catalina?

isnitnpossible that I need a usb 2 port and drive and the original copy of Catalina to make this work?

Maybe using usb 3 drives and ports and the updated Catalina is causing an error when trying to boot

i updated the post above.

Does anyone know the last macOS that could use nvidia? I had it working perfectly in e Capitan. I need it to use mini display port for my Mac monitor.

I don't know why you can't create the Unibeast installer. The oldest Mac I've tried is High Sierra and that worked fine. I used a SanDisk 32 GB USB 3.0 drive. There was someone here who had a similar problem, and it turned out it was the brand of flash drive, so maybe try a SanDisk? There shouldn't be an issue with using a USB 3.0 drive in a USB 2.0 port.

Just make sure you are using the correct version of Unibeast. Follow the instructions carefully. Make sure you are formatting correctly with Mac Extended and GUID.

The latest MacOS that supports the Nvidia Web Drivers is High Sierra.

You should black out your serial number from your image.

@Hack_The_Gibson,

The last version of MacOS that will support your Nvidia GTX 970 is High Sierra 10.13.6 with the Nvidia Web Drivers installed.

There is no support for any Maxwell based Nvidia dGPU's in MacOS Mojave or Catalina as Nvidia have not updated their web drivers to support Apples Metal 2 API.
