Thanks. I tried a different usb, again as exfat and it doesn’t show up on boot screen. It is lit up while it start so it is clear the computer sees it is there.You have to format the USB as exfat not NTFS.

Nehalem CPUs never supported Apple Hypervisor, so you won't have VMM support/native updates.Hello eveyrone, I am trying to understand is the opencore supported with my Early 2009 Mac Pro (2x 2,93 Nehalem cpus)?
Most people here are trying to extend the MP5,1 useful life until the new Apple Silicon Mac Pros are released.I'm not sure if, as of now, it is profitable for me to invest more on my Mac pro or decide that this machine is coming to an end. Upgrading to 2x cpu's, new ram and nvme will cost me 500$, is this the right solution or the time to buy a new system has come?
Will give that look sometime tomorrow, work isn't giving me much playtime at the moment.Thought about this and I think it is not showing up because of the ScanPolicy Config Key since as UEFI Wiindows, it is in an EFI partition and these are set to not be scanned in the OpenCore config created by MyBootMgr.
Change the "ScanPolicy" value to "0" which scans everything.
opencore 0.6.3 will work on your Mac Pro and allow you to do Catalina and Big Sur with native updatesHello eveyrone, I am trying to understand is the opencore supported with my Early 2009 Mac Pro (2x 2,93 Nehalem cpus)? Thank you for all your support on this! If not, the only way to upgrade to Catalina is to upgrade to the Westemere cpu's?

No, it won't unless you spoof iMac Pro full time. Btw, @izapp Mac Pro is a dual CPU and will have the stuttering audio problem.opencore 0.6.3 will work on your Mac Pro and allow you to do Catalina and Big Sur with native updates

Activate AMD hardware acceleration
I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.7.9] For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in...forums.macrumors.com
And it's not good idea to spoof IDs on 0.6.3 to update Big Sur. 0.6.3 Will not block potential unwanted firmware updates.No, it won't unless you spoof iMac Pro full time. Btw, @izapp Mac Pro is a dual CPU and will have the stuttering audio problem.
Yes, but it has to be saidFor blocking updates there is a new kext developed:

@paalb:There is no connection between the OS and the OpenCore EFI. You can use that one OpenCore EFI bootpicker to choose any of the OS volumes you have on any partition or disk in your mac. (Except for Big Sur which I belive need a different EFI config). The next time you boot the same EFI is used.
It is for all usb 3 cards.I just modded the "standard" TB3 SSDT to fit my own card (a donated Gigabyte Alpine Ridge). So that, it will ident as Alpine Ridge, but not Titan Ridge.
View attachment 1693839
There is nothing special, very cosmetic indeed. But if you have the Alpine Ridge, and you want macOS can ident it correctly, you may use the attached SSDT.
Anyway, found something interesting. If we connect a USB 2.0 HID device (e.g. the Apple Mighty Mouse) directly to the USB-C port (of course, need a Type C to A adaptor) without any hub in between. It can actually works flawlessly in Big Sur.
The infamous USB bug doesn't affect the USB 3.1 ports at all.
I am not sure if this is only true for some particular cards, or same for all USB-C cards. Anyway, apart from using hubs, one more possible solution if you need to connect a USB 2.0 HID device to the cMP in Big Sur.
Dortania Guide suggests this kernel patch:one more possible solution if you need to connect a USB 2.0 HID device to the cMP in Big Sur.

The recommended way is to always keep a disk with Mojave. The way I have solved this is that I have an old small SSD in the free CD slot with an installation of Mojave. In Bay 1 I have an SSD disk with the EFI partition and my original pre Catalina Mojave. In Bay 2 I have Catalina. Bay 3 and 4 are Data disks. When I need to go “non-opencore” I just remove the disk in Bay 1. Then the blessing will be reset and the mac is back to normal.ok, as long as the efi volume is blessed you get the boot picker and you can boot into any volume.
this seems to stick even if you go to system preferences / startup disk and select a volume and restart.
so to go to normal "non-opencore" mode you would have to boot into recovery mode and bless a normal non-efi volume?
and the blessing does not work when booted normally, it must be done from a recovery boot?
Tested, but it seems no effect on my cMP.Dortania Guide suggests this kernel patch:

Seems they are still figuring things out themselves.Tested, but it seems no effect on my cMP.
I though it wasn't work on some USB 3.0 card, but most likely just my bad memory.It is for all usb 3 cards.
May be it only works with those USB kexts.I though it wasn't work on some USB 3.0 card, but most likely just my bad memory.
This can help automate it:May be it only works with those USB kexts.
But I am too lazy to make a full port mapping for my cMP now. May be try this later.
Could be ... seems they may be trying to map cMP to nMP and then fully spoof as nMPMay be it only works with those USB kexts.
How long you wait? It can prepare a long time. How you determine the cMP is stuck?Hello
I tried to update to 11.1 on my cMP with OC 0.6.4 but the system is stuck at preparing mac 11.1 update (download was OK). Anyone has an idea ?
(I'm using the OTA upgrade)
Just "accidentally" did it. Wanted to just download to have it ready and walked away from my computer. Seems okay. Two reboots, one with blank screens scared me. Just watched my NVMe blinking away so I left it and it eventually came up.Big Sur 11.1 update has been released.
Any experience updating from 11.0.1 a cMPro with OpenCore?
It says 15 minutes remaining and it didn't move for ages (at least 10 minutes) but now it seems to move a little bit (10 minutes remaining). So it may work, I'll wait a little bit more. It's my first OTA using opencore.How long you wait? It can prepare a long time. How you determine the cMP is stuck?
