MP 1,1-5,1 Manually Configured OpenCore on the Mac Pro

[lucaspeed]

Hi, about missing USB1.1 support in Ventura+, is it possible to install a USB 3.0 PCI express card and use it for keyboard and mouse? I have a MacPro3,1

I believe that should work as Ventura has USB 3 drivers. What works for me is using an Apple keyboard (hub) and plugging in my wireless mouse dongle into the keyboard

You may be missing keyboard/mouse in the Startup Manager (hold option key at boot which can't work from USB 3.x unless EFI XHCI driver is loaded). I think OCLP comes with a USB 3 (XHCI) EFI driver so keyboard/mouse works in the OCLP menu?

This works because the keyboard is USB 2.0 and forces the built-in USB of the Mac Pro into USB 2.0 (EHCI) mode instead of USB 1.1 (OHCI) mode.

Thank you, I'll try tomorrow

Hello everyone,
I'd like to buy a RX 6600 to delay (a little bit) the purchase of Mac mini M4 pro. I want to replace my RX 580 on Mac Pro 5.1. This RX 6600 have been cleanly flashed. I work on DxO PhotoLab 7 and I need Hardware Acceleration for using DxO DeepPrime XD. Can I just switch RX580 to RX6600 without doing anything?
Thank you for answering.

I've never done that upgrade, but if you want to sell your RX580 I'm in the market for one

I'm not sure it would be worth it vs RX560. Besides, I live in France..🙃😀

I am always on the "trailing edge" of MacOS upgrades. Only recently went to Monterey on my cMP 5,1, using Martin Lo's package. works great.

So if I want to move to Ventura+, I have to do a "manual" OC install? OCLP didn't work for me.

Not possible, Monterey is the last macOS release that still runs with a processor that does not support AVX2.

So, you can only "run" Ventura and newer with OCLP. Anything that requires AVX/AVX2 will not run, like Safari JIT or Music, same for apps that require it, like a lot of Adobe apps nowadays.

Appreciate the info. As usual, you provide the best advice for these old Mac Pros.
