Hi Wurlitzer1,

You are not alone. I encountered the same problem yesterday.
The program starts and then it seems to try to download files.
I too get the error 5530. I' ve found a solution so far and therefore would really appreciate to get some hints to solve this issue.
I succeeded to install Windows 10 (!!)   on my old early 2006 imac and it seems to run without any flaws so far. But a bit slow due to the low 2GB RAM. I guess with 3 or 4 GB it would be much faster.
Best regards,

I have a mid 2012 15inch macbook pro 9,1. I was trying to use this smcflasher to just reset the smc, yes I have tried all the usual ways to reset the smc but the time and calendar never changer so I know it hasn't taken place. I use used the flasher posted here and tells me its in the wrong Appmode code and it freezes up. Its probably understandable since I suppose this flasher was made for much older macs. So I pullled the flash from the smcupdate from apple, it still tells me wrong appmode code but it doesnt freeze up. I would suspect I'd have to hex edit the hardware protection out of this flasher.
1) problem is this version is a lot bigger and are the protections in the same areas
2) i followed directions on another thread and attempted changing the values once I attempted to save it hexedit gave me an error that it couldnt save it.

Hello folks,

a friend of mine has a K600 and i modified the ROM in the well-known way (replaced existing EFI with modded EFI, which has correct DevID, VenID and BoardID. Result: No screen, card seems bricked. But card works fine in a PC (BIOS-compatible, no UEFI/GOP active).

So i scanned some roms from original mac-videocards and found out, that in the DCB-entries the head-bitmask for all connectors is set to 0x1, 0x2, 0x4, etc., but in pc-bios always set to 0xF, which means not defined/assigned dynamically.

I modded the head-bitmask in the vga-bios for both connectors to 0x1 and 0x2, and now the card is able to provide bootscreens.
But it works only in MP booting OSX/macOS, it isn't possible to start Windows, because until choosing Windows-volume he got blackscreen. The same weird happens when used in a PC, card is recognized, but no screen on all ports........

We tried also the following options:
-last rom indicator set to 0x80: Works in MP, as expected without bootscreen, but no screen in PC
-removed EFI-part: same as above.
-BIOS Information Table: Only difference was token 0x75 (uefi data) in pc-bios, i set it to "no operation", i guess it is not mandatory. Some pc-bios don't contain the 0x75-token, although having EFI-part.
-compared mac-/pc-vga-roms for GPIOs, Communications Control Block, DCB Flags: But found no differences or differences, which seem not relevant.

So, question to the professionals: Any ideas what i can also check? I'm sure that my modification is right, but incomplete.

My Sapphire 7970 flashed with a 7950 I can't even get to High Sierra. Get boot screen progress bar goes about halfway then screen goes black. But the same board works with Sierra. I think I need to reflash it but maybe with a different EFI BIOS file.
Which Sapphire 7970 do you have ?


or . .


I don't understand why you used a 7950 rom on a 7970.

I EFI flashed my Dual-X and downvolted it plus added new fan set ( common problem with these cards ).
Everything working 100%

I'm interested to upgrade a MacPro1,1 because they're already available around 60 Euro. I want to use the Low-PowerXeons L5420 (2.5 GHz) and L5430 (2.66 GHz). Are these supported? Both are Harpertown Quadcores with 12 MB L2-Cache and CPUID 1067A. Interesting is the TDP of just 50W (instad of 80 or more) and the cost: A Xeon L5420 is just under 10 Euro! The L5430 is much more expensive, even if it only has 133 MHz higher clock rate. But I have two of them, so I will use the L5430.

On my custom machines with Socket 775 + sticker mod I've exchanged all E-Xeons with L-Xeons and they're working great with OSx86. So they should be suitable for the Mac Pro, with less power consumption and less heat.

I've also read advices that it is best to use only six memory sticks (three on every board) because the processors just have three memory lines. To address more, the lines have to be multiplexed which makes them slower. I have a Supermicro server board which also uses the 5100 Nothbridge, and it only has six memory ports. Maybe they knew why.

Greets, naquaada.

I downloaded it to my Mac. You have to execute the script on a Mac anyway.

I'm hoping there is someone out there that can help me or walk me through steps or just give me advice. I have a 2009 MacPro that was successfully updated to the 5.1 firmware ages ago (I think I did it in 2012 maybe earlier). I would like to put the computer up for sale. It has upgraded ram and CPU thanks to that firmware update. My question is what will happen if the new user is to update to Catalina OSX or an OSX newer than Mountain Lion... Is there anyone on this forum that wants to buy this great computer or can suggest a good place to sell it. Sellyourmac is offering $380 (I feel like that is low, not sure if that is a good price?) and allowed me to select the 'upgraded' CPU I have but they wipe it clean and reset it to factory condition and I fear it may not work when they do that (does that reset the efi firmware back also? I don't want the new user to install the latest OSX and then can't even boot the computer (I'm not sure that is what would happen - so maybe someone can help explain that part?). Is the 5.1 permanent despite upgrading to future OSX upgrades or does new firmware come with an upgrade potentially causing this computer to not work? If so, can you just run the same firmware update each time or is there other steps? Basically I did this a long long time ago. Haven't used the computer in ages (was for studio recording). I have a son now and am getting tight on money so wanted to let it go to someone who could get more use out of it! Any help WOULD BE greatly APPRECIATED!

Thanks Jack

These are the specs on computer:

Early 2009
3.33 Ghz 6-Core Intel Xeon
32GB RAM 1333 Mhz
NVIDIA GeForce GT 120 512 MB
Currently on 10.8.5 (Mountain Lion)
