Actually yes you can update to mojave and you can install a new graphics card with a little more strength and no its not a flashed PC Card as well.

Here is what you need.

1. you will need to Mac Pro 2009-2010 firmware flasher tool

2. you will then need the firmware update 1.5 from apple.

3. open the firmware update 1.5 and don't run the pkg it won't work but leave the disk image mounted.

4. run the firmware flasher from your desktop let it run its process then follow the on screen instructions.

Part 2.

1. there is a graphics card that can handle your needs however you won't be gaming from it.

here is the link:

https://www.amazon.com/Sapphire-112...graphics+card&qid=1557063751&s=gateway&sr=8-3

this is the UEFI Support Sapphire card. it works on all 2010-2012 Mac pro's this is why you need the firmware update. it will convert your Mac Pro into a 2010 model and allow processor upgrades and even graphics card upgrades.

2. you will then have to install mojave unsupported to do this download dosdudes mojave patcher just search google and download his tool in the menu select download mojave and give it a location to save.
once finished use a usb thumb stick to create the patched drive.

3. run the installer as usual booting from the usb thumb drive.

4. run mojave installer.

5. reboot hold down the option key on startup

6. select the usb thumb drive again.

7. run in the developers window in the lower corner of your screen Mac OS post install and select you model from the list and apply patch and check box force cache rebuild.

8. restart computer shut down the computer.

9. install new graphics card and enjoy.
Why you are using a hacked install with a fully supported Mac? You don't need anything of these besides the MP4,1 to MP5,1 firmware upgrade.

Here is why.

1. Its a 4,1 a 2009 mac pro which is not supported on mojave even if you firmware update the machine and change out the graphics card and processors it wont install because the mojave installer requires apfs in order to receive system updates you have to patch the installer with the apfs. Patch in order for system update to function on mojave.. 10.14.4 you also have to patch siri wifi and bluetooth...

The firmware hack gets the graphics card and processors to work with sierra's installer without the need for a bypass

But it doesnt fix high Sierra nor mojave

This is just wrong. Once you upgrade to a MP5,1 firmware and do the subsequent firmware upgrades, APFS is natively supported. APFS is supported since MP51.0084.B00, the first MP5,1 BootROM released with High Sierra.

Btw, Apple just check the BootROM EFI version and board_id. For Apple, a MP4,1>5,1 is no different than a mid-2010 or mid-2012.

If you want to stay with HFS+ it's a personal decision, not a firmware limitation.

Tried it computer completely ignores apfs drive it wont even recognize it under holding the option key.

In 10.14.4 they changed something that is checking apfs

Again, you are wrong.

10.14.4 changed nothing for APFS behaviour with MP4,1>5,1/MP5,1 with current BootROM (141.0.0.0.0) with a non-hacked install.

All that changed with MP5,1 BootROMs you can read here on the first post: MP5,1: BootROM thread | 144.0.0.0.0 with 10.14.5 DP4
 
Have you received updates from apple at all on your machine. Please read .

This is confirmed 10.14.1 on up.

In 10.14.4. Mojave installer will try to convert the drive to apfs automatically.

Look, here we want to have perfect Apple supported installs without any hacking. A MP4,1 to become a MP5,1 just need two things:

  1. Upgrade the MP4,1 BootROM to MP5,1.
  2. Change the AirPort Extreme from BCM94321MC to BCM94322MC ($10 on eBay) or a newer one.
After that everything is exactly the same as a mid-2010. You will get all the firmware updates and have perfect High Sierra support. For Mojave, you will need a METAL supported card - once you have one, it's a suported Mac.
 
Also yes the firmware allows you to boot the installer but wont pass the installation pkg inspections do to no patch to system resources to bypass the checks.
[doublepost=1557227950][/doublepost]Again updated installer ..
[doublepost=1557228063][/doublepost]And I have the upgraded wifi and bluetooth module installed as well.

I have two MP4,1>MP5,1 here. To install 10.14.4 with a MP4,1>5,1 you need to upgrade to BootROM 141.0.0.0.0 and have a METAL supported GPU. Nothing more - no hacks - no patches.

Mr Dunderhead,
@mrdunderhead

You are seriously mistaken. You have not completely grasped the upgrade -needs- that will bring the 4,1 up to fully compatible 5,1 / Mojave standards. Hundreds, if not thousands of 4,1 > 5,1 cMP's are happily running unpatched/fully supported Mojave installs on NVMe/SSD, formatted to APFS, receiving normal updates, with all the bells and whistles. Just listen to @tsialex without being so argumentative, and you will be pleasantly surprised. He is 1000% correct, and you simply are proceeding on a false belief based on outdated information and misinformation.

TLDR:
4,1 to 5,1 Firmware + Metal Capable Graphics Card = Full software support from Apple for all of the latest updates.

Once you do the 4,1 to 5,1 firmware "hack" (it's not much of a hack since you're still using Apple's firmware) you can use APFS on your 4,1 Mac Pro.

I have a 2009 4,1 that I "upgraded" to a 5,1 firmware. Ever since then, every Apple update has worked flawlessly - Mojave, Combo Updates, Updates through System Preferences, Full Installs, APFS, firmware updates, etc. You only need the 5,1 firmware and a Metal graphics card and Apple has a list of which ones to use.

Here’s the problem... your post is not exactly correct and clear, and If OP followed your post, he would be under the impression that his machine is updated and ready. For your post to be correct, you need to go further...

After doing the 4,1 > 5,1 firmware conversion... You must do a number of 5,1 firmwares updates. The first updates have to be done with an EFI GPU, then the supported metal-capable GPU needs to be installed to do the remaining updates. Only after completing this process, will he become fully updated and ready.

This process is already well documented and the link with instructions was posted by @bsbeamer early on in this thread.

To reinforce @crjackson2134 and @tsialex , and many others, the thread referenced by @bsbeamer is an excellent and canonical guide to upgrading a 4,1 to a 5,1 and the latest firmware. I followed it when upgrading my 4,1. It now boots either HS or Mojave. It receives regular software updates from Apple through the conventional and official method - I wouldn't be interested otherwise. I should point out that when I purchased this MP from Apple 10 years ago, I did not opt for a Wi-Fi card. There's a blank spot and some dangly wires where the card should be. At least so far, not needed to "look like" a 5,1, at least for OS update purposes.

Yes, you only need to replace the AirPort Extreme if you need wireless.

The standard AirPort Extreme for early-2009 is the, now unsupported since High Sierra, BCM94321MC.

Any supported Apple AirPort Extreme will work, the cheapest one is BCM94322MC, from late produced early-2009 Mac Pros and mid-2010/mid-2012. Lot's of other Macs use the same AirPort and it's very cheap on eBay.

True, I gave an abridged version because the full instructions are well documented by others and had already been linked to this thread.

The point I was trying to re-iterate was that after you "hack" the firmware from 4,1 to 5,1 you don't need any other software "hacks" to do further updates. You just need the appropriate hardware and to run Apple's updates in the correct order.

Follow tsialex's instructions. He knows what he's talking about.
