I’ve had success copying the dosdude patch to a folder named bklt and putting it in the root folder, then running install.sh from a Single user command prompt (Cmd+s) at startup.
Would you mind clarifying what you did? Are you talking about standalone backlight patch (bkltpatch10.14.2) that Dosdude posted back in December 2018?

Yes that exact patch. I copied it to the internal drive just to make it easier to find, booted to single user mode, then ran install.sh after mounting the file system as read/write. Lots of warnings and errors, but just reboot and brightness was all back to normal.

Seems like end of the line of macOS, for the macs without Metal, now that Photos will be "Metal accelerated" in macOS 11.

Everything works perfectly after dosdude1’a Mojave patcher tool. I’m just wondering if I have to keep SIP disabled for all the patches to work? Just tried to move /library/extensions/SIPmanager.kext temporarily, boot recovery and turn on SIP, and rebooted, but didn’t look like the patches stuck. Does this mean SIP will be turned off completely in order for the patches to work properly?

I’m not sure if I’m willing to risk security just for an updated UI... is there a way around this where SIP is enabled AND dosdude1’s patches work? Or am I not understanding something fundamentally lol

If you are in an unsupported Mac yes SIP needs to remain disabled- nothing is going to happen with SIP is disabled. I have been running my I Mac using Dosdude1's patchers since High Sierra and haven't had an issue with security. and yes the patches could fail with SIP enabled

Hi, i come from High Sierra (High Sierra Patcher), was HFS+ and patched the MacbookPro 2009 MBP5,3 ROM with APFS ROM Patcher to have APFS support within the ROM (normally hasn't APFS support!, need APFS preboot patch).
APFS Patcher.jpeg
PS: EEPROM Type was an SST ... not MX ... EEPROM. APFS ROM Patcher showed no list ( I seen an screenshoot with 3 MX .. EEPROMS to select , my SST EEPROM seems to be sure detected, so no such list for selecting the right EEPROM)

I erased the SSD und formatted it with APFS before I used the Mojave Patcher to install Mojave and got Mojave installed with a no problems. Running well, also all devices like iSight, Bluetooth, Wlan.

BUT: I see now the APFS EFI patch (EFI preboot verbose text) - so I may have installed / selected APFS patch by mistake OR the Mojave Post Install Patcher patches always APFS for that MBP 5,3(hasn't normally APFS support).

HOW to remove this APFS Patch = no more verbose EFI bootet text- for an patched MacBookPro ROM usage to boot native - I think it resides somewhere in the EFI Partition (normally invisible).
If its to risky, I would let that short verbose boot, no question. But I can handle the terminal / advanced OS X knowledge to do something if you have HINTS to remove that APFS patch/ reboot verbose text.

EDIT: I investigated where the APFS Patcher could be.
Found some shell script in the Volume EFI, looks like it could be the place where the Post Install Patcher changed something for non native APFS Macs.
Anyone knows what to change / remove or replace to get native APFS boot ?

Remove apfs.efi and BOOT folder. The bootx64.efi is a renamed EFI Shell that automatically launches startup.nsh which loads the afps.efi driver, rescans for apfs volumes, then tries to boot the Mac OS boot.efi file from the Mojave disk, and if that fails it looks at all other disks.

It looks like you have an old version of the APFS patch (the for loop is wrong - drives are not numbered A-Z. They are numbed as hex)

Below is my script for Catalina on my MacPro3,1. It adds the following:
1) a mode switch to select the greatest vertical lines for my 2560x1600 display (use the mode command to find the max)
2) enables PCIe 2.0 link rate for my PCIe 3.0 card in slot 2
3) enables USB 3.x on Alpine Ridge installed cards in certain slots
4) expands search for up to 64 different partitions
5) a search for installer boot file in case of installing an update
after the above it searches for the boot file on the Catalina partition, then on the other partitions.
I put the Catalina APFS patch in a separate small HFS+ partition so it can appear in the Startup Manager (hold option key at startup) with it's own icon and label.

Code:
.VolumeIcon.icns # contains Catalina volume icon
macOSCatalinaPatcher/.disk_label # contains label (created by bless command)
macOSCatalinaPatcher/.disk_label_2x # contains retina label (created by bless command)
macOSCatalinaPatcher/apfs.efi # apfs driver from Dosdude Catalina Patcher
macOSCatalinaPatcher/Catalina_Boot.worksheet # BBEdit worksheet with commands to rebless Catalina (and update the disk label) in case that startup changes or the version of macOS is updated
macOSCatalinaPatcher/ShellX64.efi # BootX64.efi from Dosdude Catalina Patcher - it is actually an EFI Shell compatible with old Macs
macOSCatalinaPatcher/startup.nsh # modified EFI Shell script (originally from Dosdude Catalina Patcher)
Code:
echo -off
mode 320 84

set StartupDelay 1
set -v efishellmode 1.1.2

THanks for the Info about removing APFS EFI patch ( reason: I should have apfs native now by the APFS ROM patcher) . I will try. (general work with/in the EFI Folder is well known for an hackintosh user ;) )

EDIT: WORKED with the instruction from joevt
Before I did removing BOOT folder + the apfs.efi from my SSD Boot volume ( mounted invisible EFI Volume to do that!),I tested if my MacBookPro 2009 5,3 really can boot APFS native by the APFS ROM patcher (tells success, but better test it ;) )
I formatted an USB Stick with APFS and cloned my working SSD HD Mojave system on it with CCC.
In this case, I am sure the USB Stick hasn't anything within the EFI volume.
Bootet with success from the APFS USB Stick :) !!! So I made the changes in the EFI volume of my SSD HD.
Also boots without the apfs efi verbose screen native on my SSD HD.
Thanks to dosdude1 for the APFS ROM patcher and many wirings her to be sure to NOT flash if the patcher asks for EEPROM type you don't know! In my case the ROM patcher didn't ask to select an EEPROM type, it detects my SST .. EEPROM type & knows to it for flashing with success.
IDEA: Perhaps some Info in the FAQ of the patchers for same tasks like me would be great - remove apfs efi patch after flashing patched ROM for native APFS booting.

I’m not sure if I’m willing to risk security just for an updated UI... is there a way around this where SIP is enabled AND dosdude1’s patches work? Or am I not understanding something fundamentally lol
What specific "security risk" do you cite? Please be very specific with actual facts. Tnx.

Hi all,
Mojave 10.14.6 (18G5033) SecUpd2020.003 successfully installed on MBP5,3 (After Distibution file modification)

Restarted on USB drive and reapplied Postinstall with Force Cache rebuild after update.

Only replaced AppleGVA.framework (for videos fluidity), HIToolbox.framework (for dock menu shadows), SiriUI.framework and Siri.app (for waveform) and all seem to be working properly for now.

Hi, i am new to MBP 5,3 (Nvidia 9440M/9600M) and now have also Mojave / Sec -03 on it. ( I used APFS ROM Patcher to boot native APFS)
Question:
Does usage of an other AppleGVA.framework make video playback better / less CPU/GPU % load?
From what Mojave version have to taken the AppleGVA.framework (for videos fluidity)?

I have an backup of the 10.14.6 (without any sec updates) + High Sierra (with sec updates) and could use AppleGVA.framework from one of them. I think i should use the framework from High Sierra, rigth?

Got 10.14.6 set up and running on a MBP 7,1 and the Track Pad issues all went away when I saw the post about Onyx. Once I ran it everything that was an issue seems to have been dealt with. No issues since.

But on my 3,1 Mac Pro works great, but will not boot on its own. the 10.14.4 install boots on its own just fine. For 10.14.6 it'll only boot when I use the Startup Manager. Which goes right to the Mōjāv Icon with the arrow in a circle and the second I click on it or press enter, the machine boots right up and works great. I have tried running Onyx on it hoping for the fix I got on the 7,1, but no joy. So I only have to get past the self-boot issue and I'll be golden.

At one time I had 10. - 11, 12, 13, 14 & 15 all on the 3,1 and there were no problems. But I only loaded it to trouble shoot for others and to play with it. I have since slowly moved up and now would like to use 10.14.6 as my main OS. I'd go Catalina, but I have a couple 32bit apps that are mission critical.

I've grabbed all the Pro Dev BS (Big Sur) Betas. Not sure what I'm going to do with it all, but it's been added into my dense and ever growing collection.

Thanks dd1!

Hi, i am new to MBP 5,3 (Nvidia 9440M/9600M) and now have also Mojave / Sec -03 on it. ( I used APFS ROM Patcher to boot native APFS)
Question:
Does usage of an other AppleGVA.framework make video playback better / less CPU/GPU % load?
From what Mojave version have to taken the AppleGVA.framework (for videos fluidity)?

I have an backup of the 10.14.6 (without any sec updates) + High Sierra (with sec updates) and could use AppleGVA.framework from one of them. I think i should use the framework from High Sierra, rigth?
yes use the one from High Sierra :)

@dosdude1 e1 Your 10.14.14 accel patch works on a 2011 21.5 iMac (AMD Radeon HD 6750M ) ? If it does, shall i run the script once i booted or on the installer? My doubt came beacusei saw that on your patched macbook you use intel integrated graphics and i did not know if it worked as well on AMD graphics. Thank you

"Currently, it is not possible to get full graphics acceleration when running Mojave on a system with a Radeon HD 5xxx or 6xxx series video card. Mojave will be almost unusable without graphics acceleration. This includes the 15" and 17" MacBook Pro systems (MacBookPro8,2 and 8,3). If you want to enable GPU acceleration on these machines, you'll need to disable the AMD video card (This will work on MacBook Pro 8,2 and 8,3 systems ONLY. You CANNOT disable the AMD GPU in an iMac.) Weird colors will also be produced when running Mojave with one of these video cards installed/enabled. To disable the AMD GPU on a 2011 MacBook Pro 8,2 or 8,3, follow the guide found here."

Well, that still doesn't apply to RADEON 5XXX or 6XXX. You're free to ask dosdude1 but AFAIK the situation didn't change since the first post. Your best bet is installing a metal compatible GPU.
