macOS Tahoe - OCLP-Mod and develop of first version with Real Mac (Pre-Release Tahoe Beta 3)

[fernando.c.neves]

This topic is for the ones who trying to made macOS Tahoe (Beta 3 and beyond) works with Old Real Mac.

 

*** All the credits of OCLP-Mod goes to @laobamac_yyds for the forked version of OCLP Project and the amazing develop of his OCLP-Mod. ***

 

This is my first try to made my MacBook Pro Late 2011 - i7 Quad Core - 16GB 1600Mhz DDR3 - Intel HD Graphics 3000 with 512MB - AMD Radeon HD 6770M 1GB - MacBookPro8,3 (Real Mac) to boot with video acceleration on Tahoe.

 

Do this after installed @laobamac_yyds OCLP-Mod Pre-release and rebooted

With those commands, your acceleration will work but transparency is not working at all. => MacBook Pro Late 2011 - 17 inches - Intel HD Graphics 3000 (512MB) / AMD Radeon HD 6770 1GB. MacBookPro8,3 - Real Mac.

Need SIP Disable 0803...

 

 

sudo mkdir /Volumes/root

 

sudo mount -o nobrowse -t apfs /dev/"Your Tahoe Disk (Apfs)" /Volumes/root

 

sudo mount -uw /Volumes/root

 

cd /Volumes/root/S*/L*/Extensions

 

sudo rm -R /Volumes/root/System/Library/Extensions/AppleIntelHD3000Graphics.kext && sudo rm -R /Volumes/root/System/Library/Extensions/AppleIntelSNBGraphicsFB.kext && sudo rm -R /Volumes/root/System/Library/Extensions/AppleIntelFramebufferCapri.kext

 

sudo cp -R /users/"Your user Name"/Desktop/Drivers/Apple* .

 

cd /Volumes/root/S*/L*/Ext*/AppleIntelSNBGraphicsFB.kext/C*/M*

 

sudo cp AppleIntelSNBGraphicsFB AppleIntelSNBGraphicsFB.backup

 

Those commands make your Intel HD 3000 Graphics with (1,5GB VRAM, 2GB, 3GB,4GB (4080 MB)) - Not working on Tahoe (Sequoia works)

 

1,5GB

sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x40|\xc7\x45\xBC\x00\x00\x00\x60|g' AppleIntelSNBGraphicsFB

 

2GB

sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x40|\xc7\x45\xBC\x00\x00\x00\x80|g' AppleIntelSNBGraphicsFB

 

3GB

sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x40|\xc7\x45\xBC\x00\x00\x00\xC0|g' AppleIntelSNBGraphicsFB

 

4GB (4080 MB)

sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x40|\xc7\x45\xBC\x00\x00\x00\xFF|g' AppleIntelSNBGraphicsFB

 

sudo kmutil install --volume-root /Volumes/root/ --update-all

 

sudo bless --folder /Volumes/root/System/Library/CoreServices --bootefi --create-snapshot

 

Attached files: Kexts + Command (Terminal).zip ***Unzip at your Desktop (To use these commands, or adapt to new location)***

 

Ps: I'm using two SSD's one with Tahoe Beta 3 and another with Sequoia 15.5, to manage how to implement the patch for Intel HD 3000 Graphics at least...

 

I get Acceleration in Tahoe Beta 3 with Safari over Youtube on videos 1080p 60fps... Smooth, but the transparency of the system is with some bug's...

 

I guess this is far as I can go with Real Macs patching.. Now if @laobamac_yyds can help it will be appreciate.

 

Another thing that I observed is that FrameWork is not included in @laobamac_yyds patch, so no acceleration from OCLP-Mod Pre-Release. I managed to install using this commands:

 

Install Legacy Video Patcher... => @chris1111 Many thanks for your Legacy Video Patcher, is working like a charm until Sequoia 15.5 =>

@chris1111 Source code => https://github.com/chris1111/Legacy-Video-patch

Compiled version => https://drive.google.com/file/d/1AG9CivELxxE0bPKisGy9qPuaGYUvP0AA/view?usp=sharing

 

And after use these:

 

sudo mkdir /Volumes/root

 

sudo mount -o nobrowse -t apfs /dev/"Your Tahoe Disk (Apfs)" /Volumes/root

 

sudo mount -uw /Volumes/root

 

sudo kmutil install --volume-root /Volumes/root/ --update-all

 

sudo bless --folder /Volumes/root/System/Library/CoreServices --bootefi --create-snapshot

 

sudo reboot

 

Thats all folks.

 

Regards,

Fernando.

one quick question here.....is this going to work with HD5000?

 

I've got my MacbookAir 6,1 up and running (will write a tutorial somewhere here, not sure if anyone did that yet) and before I start breaking it again I would like to ask the author if he feels this would work for my case?

 

Thanks!

Very Good !!!  Intel HD3000 on new MacOS  🙂

 

Cheers
