Mac Pro Firmware Hack

The Mission

  1. Mac Pro 2010 Firmware Update
  2. 2009 Mac Pro Firmware Hack

There has been much controversy on removing the firmware lock on a MBP, MBA, or similar Mac’s. The MBA is a bit more complicated without a specialty tool to interface with a header on the board. We use to have to remove the board, scratch back traces, and solder directly to them which can be seen in EX-1.1. This is just short of replacing the entire chip, which is what we are all trying to avoid right? I also have a project I have been forking on called the iFLRT (Firmware Lock Removal Tool) that can be found HERE. Donate what you can to keep my development process alive, every little red cent helps.

First you need to understand what the firmware lock is and how removing it will affect you. Then maybe you will be able to decide if this procedure is for you. In most cases a MBP has been purchased from a third party who may have stolen it or simply forgotten to remove their iCloud account. In this case the symptoms would be a four digit pin lock when the OS loads. When you try to do a re-install you are met with a lock screen shown in EX-1. This is the result of the Mac being most definitely locked from the cloud. There are two options from this point which are explained below.

EX-1

EX-1.1

After your Mac Pro is powered off, hold the power button down until you see the power LED blink quickly or you hear an audible tone. The blinking LED will precede the tone. Your computer should now begin to update the firmware on its own. May 12, 2011  The hack was first discussed on the netkas.org forums and was later detailed by Ars Technica’s Chris Foreman. Loading the new EFI firmware onto a 4,1 model (early 2009) Mac Pro. Dec 11, 2018  Firmware updates aren't installed automatically alongside macOS on Mac Pro (Mid 2010) and Mac Pro (Mid 2012), unlike other Mac models. Follow these steps to ensure that your Mac Pro receives any available firmware updates when you update or reinstall macOS. If you've tried to reinstall macOS on these models using macOS Recovery and see the screen that says a firmware update is. One of the users of MacBook Pro has a trouble with his Firmware password, he cannot able to start his device using the Hard disk drive. He couldn’t know how to reset or remove the Firmware password Here are some solutions to resolve this problem. Solution 1: Add or Remove RAM from Mac 1.

NOTE: If you have a 2010 model MBP or earlier all you have to do is change the amount of RAM in your MBP and clear the PRAM. This is all you have to do to get past OS lock. But you will still have a firmware lock as far as I know as in many cases this has happened. There have been occasions where the firmware lock has also been removed but I cannot contest to any exact models. Remember to set the Mac up like new and register the Mac with a new iCloud account to avoid any future lock-downs.

Option A: You can assume that a firmware lock was never set and brute force the firmware lock with a HID device such as a Teensy. This operation can take quite a while because it has to go through 10,000 iterations of possible pass-phrases in the worst case scenario. This will ONLY work if it was set by the iCloud!

Option B: You can assume that a firmware lock was indeed implicated when the MBP was set up and that the brute force method will not work. This can save you time but requires you to have a SPI programmer at hand such as the Bus Pirate or in this case a Raspberry Pi.

In A Nutshell

I won’t waste time on the brute force method as I believe it isn't relevant in most cases. I will focus on the process of flashing the EFI chip that is usually easily accessible by removing the Macs’s back-plate, either by a small 15X2 header, 17X2 header, or the 8 pin SOIC chip itself. You can see an image of the SOIC8 chip in EX-2 and the header in EX-2.1. The process is simple but requires a bit of knowledge in micro controllers. I will use the easiest and cheapest route that I know. The process goes briefly like this:

  • Oct 09, 2019  To apply the firmware update on your MAC. You will need to follow the instructions given here properly to get better results as you can. Here we are going to share the latest tips and tricks about MAC Pro Firmware Update High Sierra on your system. The working firmware upgrading guide will help you to update the firmware on your MacBook Pro.
  • A DMG file contains the actual firmware update. Now that you’ve downloaded the DMG file, double-click to open it’s contents. A new Finder window opens that contains a.PKG file – it’s this update that you need to install, by double clicking on the icon (or use right click and select Open).You’ll also notice that a disk drive icon appears on your desktop which can also be opened to.
  • Jan 28, 2015  If the password you’re having trouble remembering is a general Mac login or administrator password, you can reset it with these instructions instead. Using the the Apple ID approach on boot is typically the easiest for modern Macs. 1: Try to Reset or Disable with Firmware Password Utility.

EX-2

EX-2.1

Step 1 – Buy a SPI programmer such as the Raspberry Pi and a clip to interface with the chip. You can find the Pi on eBay, doesn't matter what model and you can find the Pomona SOIC8 clip there as well, usually with the female-to-female wires included. If you have a MBA then you can contact me about purchasing a clip for the header.

Step 2 - Read the chip three times and verify MD5 check-sum to ensure you have a good backup if things go wrong.

Step 3 – Make a copy of the dump and open it in a hex editor. I use Notepad ++.

Step 4 - Search for “$SVS” in the dump and you should find 2 instances. The first instance is what you will need to clear out making sure to keep the file length the same. It is safe to replace it with an empty value such as “ÿ”. The string including the $SVS should be replaced, you can copy and paste a portion of the string below if needed. each 'ÿ' is 2 bits and 8 bits make a byte So keep that in mind when you replace the string. The file size has to be exactly the same size as the chip or it will return an error.

This is an example of what to replace in a hex editor.

Step 4.1 – Get a clean dump that is not firmware locked from the community making sure you use the correct EMC and processor architecture. Make absolutely sure it is the same size as your original dump which is usually 2, 4, or 8 MB. If you go this route then you will need to replace the serial of the donated dump with your own serial in order to not register over their Mac. You can do this my simply searching for 'override-version' and on that same line there will be an 11 to 12 digit serial number that you will replace with your own. I also have a repository found HERE which you can use to search for your EMC number and I may have a clean dump.

Step 5 – Hook your programmer up to the chip, erase the chip, write the new dump and verify it.

Step 6 – Remove the clip and turn your Mac over to turn it on and test. You will immediately use the hot-keys to get to single user mode to test.

Step 7 – If you do not get to SU mode or the Mac does not boot right you will need to erase the chip and write the old dump back to it. You then can exhaust other options.

Step 7.1 – If you do get to SU mode turn the Mac back off and use the hot-keys to clear the PRAM. This will get rid of the 4 digit lock at OS load. Or you can simply re-install at this point. Remember to register the Mac to a new iCloud account to avoid future lock downs.

NOTE: Here are a few things worth mentioning..

  • Make sure your chip is supported in Flashrom which is the program you will be using to talk to the chip.
  • You need to make sure the clip makes a solid connection to avoid misreads.
  • You need to verify your chips datasheet to correctly identify the pin-out to the SPI programmer.
  • The wires connecting the clip to the SPI programmer need not be any longer than 8 cm.
  • The battery may need to be connected due to voltage drop in special cases (RARE).
  • The power cable should be removed from the Mac during the entire process, up until boot time testing.
  • Always make sure to back up your original dump and verify the write.
  • Optionally you can wire in resistors between the SPI programmer and the clip on the 3.3v pins.

That is the entire process in a nutshell. Now I will explain how you can do this in as much detail as possible. The first thing that you will need to do is pick up your entire inventory before you begin. After that lay everything out and do some testing. Make sure your chip is supported having the datasheet and any diagrams available. I also suggest after you get the clip connected to all the wires you check for continuity from the clips pins to the end of the F-F wires on each pin.

Down And Dirty

NOTE:Read this guide in its entirety before you attempt to do anything to your Mac; Read it twice if you have to. I would also like to take this time to tell you that I am not responsible for any damages to your personal property or your physical/mental wellness if the guide is used. There is no guarantee, implied or expressed, in this procedure. You are following this guide knowingly and accept that damaging your property may be the outcome. Although I do not for see that being the case as I have tested this method many times. With that being said, let’s get started.

This is the list of things you will need in order to successfully and easily fix your MBP:

  • Raspberry Pi (Doesn't matter what version) with power supply and an SD card with Rasbian installed.
  • 8 Pin Pomona SOIC clip or my EFI Easy Flash clip.
  • 8 Female-to-Female wires.
  • Flashrom.
  • Your chip's datasheet (To verify the chips pin-out and voltage requirements).

Mac Pro 2010 Firmware Update

Now, I am going to assume that you at least have some experience in Linux and basic troubleshooting skills. You will run into problems and they are not all going to be the same as everyone else’s problems. So critical thinking is also required although I have not added it to the list. When you have your Raspberry Pi all set up and Raspian is booted up you will need to set it up for the first time. if you have already set it up go to the terminal and type:

sudo raspi-config

While in this configuration screen make sure to turn SPI on under Advanced. You may also turn on SSH if needed.

Then you will need to do an update by typing:

sudo apt-get update

Followed by an upgrade:

sudo apt-get upgrade

Optionally doing a distrobution upgrade:

sudo apt-get dist-upgrade

Now we have to install a few libraries that Flashrom relies on:

sudo apt-get install pciutils

sudo apt-get install libftdi-dev

sudo apt-get install libusb-dev

sudo apt-get install libpci-dev

Then you need to download the latest flashrom version:

sudo git clone https://github.com/stefanct/flashrom.git

It will be downloaded into a folder called 'flashrom' so change directory into the folder:

cd flashrom

And make it: Hacked spotify mac.

sudo make

Then install it:

sudo make install

Now we need to modify the blacklist by commenting out the SPI entry if it exists:

Sudo nano /etc/modprobe.d/raspi-blacklist.conf

You will need to put “#” in front of the line that reads blacklist spi-bcm2708 effectively commenting it from the configuration file. If there is nothing in the file don't worry about it, that means SPI is not blacklisted. You can then save by hitting CTL+X, Y, and ENTER. You will then need to hook the wires up to the Pi and to the clip according to the diagrams below and your chip's datasheet. In MOST cases it will be just like what you see below.

The actual pinout for most 25 series chips depicted above is as follows for those of you who need a more definitive answer:

  • Pin 1 of the chip (marked with a small dot) which is CS (Chip Select) goes to pin 24 on the Raspberry Pi.
  • Pin 2 of the chip which is MISO (Master Oin Slave Out) goes to pin 21 on the Raspberry Pi.
  • Pin 3 of the chip which is WP (Write Protect) goes to pin 17 on the Raspberry Pi. (Usually Not Needed)
  • Pin 4 of the chip which is GND (Ground) goes to pin 25 on the Raspberry Pi.
  • Pin 6 of the chip which is MOSI (Master Out Slave In) goes to pin 19 on the Raspberry Pi.
  • Pin 7 of the chip which is HOLD (Hold) goes to pin 17 in the Raspberry Pi. (Usually Not Needed)
  • Pin 8 of the chip which is VCC (Positive Supply Voltage) goes to pin 17 on the Raspberry Pi (3.3v)

Connect the wires on the clip to the Raspberry Pi making sure it is turned off following the diagram above. The GPIO pin that is closest to the corner of the Raspberry Pi is pin 2, keep that in mind or read the manual. After you are all connected you will place the clip on the chip snugly and turn the Pi on. Go to your working directory and run the following commands using some discretion.

**Start of the Flashrom process**

Get to the help page:

sudo flashrom --help

List the supported chips:

sudo flashrom –L

Read the flash chip by using the below command three times:

sudo flashrom –r ~/efi/read1.bin -V -p linux_spi:dev=/dev/spidev0.0

Erase the chip after you have verified all three reads have a matching MD5 hash: Brother scanning software mac os x.

sudo flashrom -E -V -p linux_spi:dev=/dev/spidev0.0

Using the methods explained above either modify or get a clean dump making sure it is the same size as the original ROM and write it to the chip:

sudo flashrom -w ~/efi/new.bin -V -p linux_spi:dev=/dev/spidev0.0

Verify the chips contents with the file that you just wrote to ensure its integrity:

sudo flashrom -v ~/efi/bnew.bin -V -p linux_spi:dev=/dev/spidev0.0

If you have not run into any problems you will have a freshly flashed chip. If you did run into issue, use the forum here to start a thread and we will help you troubleshoot your error messages. The reason I always use the –V command is to ensure a verbose output. At this point shut your Pi down and then remove the clip. You will then replace your power supply to the Mac and then turn it on using hot-keys to try and get to SU mode. If you get to SU mode you will shut back down and use the hot-keys to clear PRAM and reinstall setting the Mac up as a new machine. Make sure to register it with a newly created or existing iCloud account to prevent further incidents. If you did not get to SU mode you will need to erase your chip and try again.

That’s it folks, this is the long awaited guide that has more than enough information to get you through the process. It is specifically designed to save you money in the recovery of your Mac and to seamlessly work through any prior issues you may have had using Flashrom with a windows PC.

Apple upgraded the Mac Pro in 2010 with Westmere Xeon CPUs, including a dual six-core option that can power through multithreaded workflows with aplomb. But what if you don't want to shell out all that money for a new Mac Pro? A clever hacker has discovered a firmware hack to effectively transform 2009 vintage Mac Pros into 2010 Mac Pros, including compatibility with Westmere CPUs, faster RAM, and audio output via Mini DisplayPorts.

A member of the forums on netkas.org—where lots of hackintoshers and system tweakers exchange tips—discovered the mechanism Apple uses to install EFI firmware updates. By exploiting that mechanism, a user named 'MacEFIRom' was able to develop scripts to force older, 2009 Mac Pros to accept a firmware update intended for the 2010 Mac Pros. That firmware enables a 2009 Mac Pro to act and operate just like the 2010 Mac Pro.

The firmware enables three main features for 2009 Mac Pro users. Perhaps of primary interest is that users will be able to install 32nm Westmere Xeons, including six-core variants used in the high-end 2010 Mac Pro, into their older machine. Single-socket machines can use W-series CPUs, while dual-socket machines will need dual-QPI enabled chips including the E5600 and X5600-series chips. (A source who applied the firmware update told Ars that Westmere CPUs are identified with 'B1' stepping in the identification code.)

Even if you didn't plan to upgrade the CPU, though, there are other benefits. Some Nehalem CPUs can support 1333MHz DRAM speeds, but are limited to 1066MHz on the older Mac Pros. The firmware update will enable the full 1333MHz speed if you have a CPU and RAM combo that can support it. And, the updated firmware will channel audio signals through the Mini DisplayPorts on installed GPUs, making it easier to use with HDMI displays.

The firmware trick works because Nehalem and Westmere Xeons use same chipsets and sockets. As we noted in our review of the dodeca-core 2010 Mac Pro, the internals are no different form that of the octo-core 2009 Mac Pro we reviewed in 2009. Apple seems to have merely tweaked the firmware and offered new CPU options for 2010.

While several users have applied the firmware hack with success, there are a few caveats to note if you plan to do it yourself. Apple does not consider the CPU in any of its machines to be a user-serviceable part; swapping it will void AppleCare, and so will applying an unsupported firmware update. The tool that MacEFIRom released allows users to revert an upgraded 2009 Mac Pro to the original firmware, so it's possible to undo the hack before taking it in for service. However, some refurbished 2009 Mac Pros have a special firmware revision that is not publicly available—if you have one of these machines, you won't be able to revert back to stock.

Also, since your 2009 Mac Pro thinks it is a 2010 Mac Pro (it will report itself as a MacPro5,1 in System Profiler), your original system install discs will no longer work. You'll need 2010 Mac Pro restore discs if something catastrophic happens and you need to reinstall Mac OS X.

2009 Mac Pro Firmware Hack

Finally, newer Mac Pros have a newer version of the System Management Control firmware. The SMC controls (among other things) the cooling fans, and the newer version in 2010 Mac Pros can make some GPUs run cooler. However, the older firmware for the 2009 Mac Pros doesn't appear to adversely affect the operation of the machine in any way.
