Evvai 😄

Oppure " Rename " ... Rinominalo ( tasto destro sul file ) HfsPlus.efi diventa -> HfsPlus.efi.bak apfs_aligned.efi diventa -> HfsPlus.efi

you will gain a bit in performance and also a better thermal design

organize for class tab and see display controller from your file i can see only 4090 gpu are you full fill all your nvme slot? i do not remember if Proart disable some pci slot if it is fullfilled have a look to your manual

Anto65, ho aggiornato a Tahoe 26.2 beta e tutto è filato liscio e funzionante ma una curiosità: come mai a te, nell'immagine di sopra porta l'aggiornamento incrementale di soli 1,75 GB ed ha me (sia attivanto in EFI kernel weg versione modificata 1.7.1d7 che disattivandolo completamente) mi è uscito sempre l'aggiornamento completo di 17 e rotti GB?

Hi @yandong31, I saw that you also asked the question on Discord to get CorpNewt (aka CorpGhost) involved in this topic. I'm happy about that and would like him to participate as well to shed some light on this topic, even though it may not be his area of expertise 🙂 (sorry) Getting back to us, you're not considering the fact that when these discussions first started, the DevirtualizeMMIO quirk wasn't so “famous” and the version of OpenCore (0.6.x) was much less refined than the one we use today (see, for example, the quirk section and the bootloader's memory manager itself). I and other users who had bought an AMD trx40 (top of the range at the time) clashed over the fact that OSX would not start on these machines. The first consideration that came up was that AMD's kernel patches needed to be updated (but this was not the case with subsequent tests). From here, the questions I asked vit9696 on Insanelymac at the time also consider the fact that DevirtualizeMMIO was used exclusively to run old OSes on Intel and for little else. So, with my obvious shortcomings on the subject, I started doing some debugging to understand why OSX wasn't working on my PC and those of other unfortunate colleagues (TRX40 users). Vit9696 and DownloadFritz (chief developers of the OpenCore project) tried to explain to me in a cryptic way (at the time) how to debug, and you can find these tests on InsanelyMac. It wasn't easy to talk to them for two reasons... the first is that I'm not a technician on these topics, and the second is that they consider the kernel patches we use to be junk. That said, after running all the tests (and there were 19 MMIO areas for my system at the time), they said that the AMD patches for the kernel were “borked.” * Here I'll open a small parenthesis for further explanation. None of us could understand at the time whether this statement was correct or not, so we devoted ourselves completely to virtualizing OSX with ProxMox. and it was a wonderful experience for all of us 🙂 Some time later, without any changes to the AMD kernel patches, in a more recent version of opencore (with new quirks and openruntime), the TRX40 systems began to overcome the initial hang due to lack of memory space, but any attempt to start OSX failed miserably.* So we started reviewing the various combinations of quirks and MMIO areas, and one user (Pavo) announced that he had managed to run the OSX of the time (perhaps Mojave or Catalina) in “bare metal” (without virtualizing in ProxMox). There were several problems, but the system worked 🙂 From there, further questions arose about how to optimize our systems. Some restarted instead of shutting down, others gave KP errors under certain conditions (sleep/wake). And much more. And so began the story that more is better! 😛 We started trying all the combinations and got to the point where, by reassigning all the MMIO areas (skip 1) except the last three of each motherboard manufacturer at the time, we were able to get OSX working perfectly in all its parts Now, I don't want to bore you and any other readers with other studies and tests carried out at the time, but we achieved a system of exceptional usability for all users. Some time later, a user who had studied some patches for Adobe products (XLNC) posted a new method on the trx40 thread. Without making the MMIO declaration in the whitelist but activating the DisableWriteVariable quirk, the same results were achieved! Personally, I never applied it on TRX40 except to verify what he said about his method, but it worked. Now I often use it with new users who are unable to do things themselves to get the correct MMIO for their machines, just to get them started and make them enthusiastic that the money they spent on their PC wasn't wasted 🙂 I hope that with this long explanation, you have a better understanding of my point of view, and I reiterate my happiness that others today (which is easier than it was then) are showing interest in this topic 🙂 Ah, another topic we tried to understand was associating these MMIO areas with parts of the BIOS of motherboards and controlled devices (USB, SATA, NVMe, NVRAM, PCIe slots, and so on). We didn't succeed, and no one has ever done so to date 🙂

Ciao, il buon Anto non ha modificato il kext ma lo ha riportato da noi dando anche le indicazioni di chi lo sta modificando Diventerà ufficiale quando sarà approvato da vit9696 (curatore di opencore e di quei kext), e lo diventerà solo quando avranno testato lo stesso con vecchi sistemi e piu' pc/mac possibili..pero' come ho fatto io..se ne trovi uno che ti va bene e non ti da problemi per te...lo utilizzerei (io lo faccio con uno ancora piu' vecchio di questo di loabmac (lo sviluppatore cinese) Detto cio' non credo che sia il kext modificato a crearti il problema del riavvio o del doppio monitor che si aggancia o meno con gli altri kext...

1804-patches_OC.plist.zip tada ChorpNewt (aka CorpGhost) did it again! Now also asus x870e Hero 1804 works 🙂

do not update for now. it needs new ACPI patches if we are lucky 😉

Is the resize bar enabled in the BIOS? Also run a CMOS to force detection and reset the NVRAM on the Mac, reboot from Mac and see what the card says under Information/Graphics and Monitor. Basically, it should see it. I get an error without WhateverGreen.kext. however it is the 4090 that predominates the slots, you have to try to temporarily remove it and try only the 6600 in pcie 1, once the mac is started insert it in the device properties of Opencore and put the boot arg nv_disable, put them back as they are now and try to start

Put the 4090 in the PCIe x16_1 slot Place the second GPU in the PCIe x16_3 x4 slot, but I doubt you'll have room at the bottom to insert it. sorry my english

in key management have you cleared secure boot keys? but it should be done because you see boot menu i would try to disable resize bar option and then also 4g in two different tries...but...now i am out of good ideas

is it watercooled or you can remove easily it? because it is weird if your RX is working well in other os can you connect only a monitor to RX 6600 and try to boot to your USB as i see in your video? then will think to full installer problem 🙂 I have a doubt if it is a problem with installed 4090

bios settings are well done for OSX? usually is possible to load default settings, disabling secure boot keys and fast boot, also to set CSM off and UEFI on, 4G on should be enough for many setups

then with my efi you should see a "dos" verbose scrolling lines Boot menu i see there is from gtx 4090? We should see it on RX 6600 usb pen seems to be formatted well

Not useful for AMD using OC simplify your EFI misses completely MMIO whitelist part i would suggest to use my initial EFI in this post (updating kext, amd kernel patches and opencore) and post again your result and EFI

Grazie Grazie e ancora Grazie per i vostri consigli finalmente ce lo fatta o aggiunto i DProperties e aggiunto # per disabilitare igpu e......... voilà

Giorno a tutti dopo parecchio tempo stamattina mi son messo a provare a metter su tahoe , seguito le indicazioni datemi da @Anto65 ( usb / weg / smbios ) e andato tutto liscio installato al primo colpo . Ma rimangono due cose ancora da risolvere ..... Audio che me lo da solo su hdmi ( utilizzo AppleALC ) e ethernet ( utilizzo il kext lucy ) , qualche info ? Grazie

se in sonoma ti andava senza nulla non devi mettere niente sempre se parli della wx4100 (scheda grafica su PCIE) se non va , forse e' stato tolto il supporto. qui dicono che va: in sequoia e Tahoe

tuto liscio, aggiornamento incrementale di pochi gb

ho già provato su tutti e due gli slot, grazie comunque Perdu, fa nulla userò 2 schede wifi, vanno comunque bene sto scrivendo appunto da questo pc😂

@danysi prova a dare qualche risposta (a volte senza sapere purtroppo (intendo per me)) da questo config vedo dichiarati due kext per l'audio, ma non e' per questo che ti va male il wifi ho la schedina simile montata e sino a ventura va senza nessun kext (sia il wifi che il BT)
