Use Kext utility to clear clear caches and rebuild the bindings.. then reboot. It should work. Mine shows 1536MB.

Hello to all:
After do the command (sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x40|\xc7\x45\xBC\x00\x00\x00\x80|g' AppleIntelSNBGraphicsFB ) with x80 instead x60, maintain my vRAM to 1.5 Mb.
I have 8 Gb RAM. Then I want ask. If upgrade to 16 Gb, will reach 2 Gb?
I know the HD 3000 have the limitation to 1.7 Gb shared RAM, but in other forum they said set to 2 Gb will use the total 1.7 Gb.
Regards

hi, i have the same mb-pro; does worth/is noticeable/makes a difference on the performance of the machine? I got 16gb of ram and the system is on a ssd.need help.. i tried this on my early 2011 macbook pro but no sucess. I used the mojave patch using the kext utility but file cant be copy as mentioned in kextutility--cant copy source file error. did i miss something please email me for the help. i badly need this hack
-------------------------
UPDATE: successful after SIP disabled/restart then patched.
hi, i have the same mb-pro; does worth/is noticeable/makes a difference on the performance of the machine? I got 16gb of ram and the system is on a ssd.
I may have issues, and severe ones. It may be connected to this „hack“. every time i do something that will fill up the vram (previewing huge image, scrolling a webpage that perpetually loads more and more images) i reach a point where the whole ui glitches out. More and more ui elements become scrambled until nothing works anymore. No overheating. Reboot cures it perfectly. Had set the vram to 1,5 gb, i guess the hd 3000 isn’t able to handle that much and literally gives up.
i have 16 gigs installed on my late 2011 13 mbp and the system on a ssd. i have never seen any performance gain from this hack, because I didn't notice any drop in performance each time the hack was disabled after a security update of hight Sierra
no issues at all, only one I have was when I put a second ssd on the dvd drive bay with an adapter sata 2, but if you use a sata 3 theres no problems, I now have two ssd's inside the machine.Hello: Mine is a MacBook Pro 17 2011
The dGPU fail and hack the firmware to override the chip. Now Install 16 Gb and using VectorWorks 2017 haven't problems yet.
Next week I will install an SSD replacing the HDD to increase its speed.
Do you have issues?
Regards

I wouldn't know as i have not tried Catalina on my 2011. I am not sure it will work.
It will work, for a simple reason, Catalina "Video Patches" use exactly the same GPU drivers/kext and frameworks used previously in Mojave.
Use this already tested and working also in Catalina:
IntelHD3000 VRAM increase pre-patched HighSierra/Mojave/Catalina
Thanks a ton for providing those pre-patched kexts... they're super-handy! I've experimented with installing them in both Mojave and Catalina on a Macmini5,1 (each OS having been installed via DosDude1's tools).
Here's the thing, though: I can see that the vRAM ceiling has been raised, but I'm not seeing any practical benefit from doing so. My Macmini5,1 has 8GB of RAM installed, and normally allocates 512MB of that for vRAM. I've run it with the ceiling upped to 2048MB, 1536MB, and 1024MB, and I haven't been able to find a video mode that does work with the increased vRAM but doesn't work with the stock configuration. In fact, with 1536MB or more, I've observed that the desktop UI graphics become glitchy.
Considering all the effort that's been put into figuring out how to enable the HD3000 vRAM increase, it wouldn't make sense if there were nothing to gain from it, so.... what am I missing?! - Thanks.
your machine is a Macmini5,1 so it means that you use an HDMI output to an external display
Increasing VideoRAM in some applications or games has some improvements, but there is a minimum of glitches, however to find if you applied correctly the patch you should download and install this app:
https://apps.apple.com/br/app/opengl-extensions-viewer/id444052073?l=en&mt=12
that tells how much VRAM is allocated and subtracted from the RAM.
However your machine is a Macmini5,1 so it means that you use an HDMI output to an external display, the VRAM increase patch has more effect on MacBook Air / Pro laptops, that have an embedded LCD with fixed screen resolution.
Hi,
Could you help me with Intel HD 3000 (512 to 1536MB) files for macOS Catalina?
https://forums.macrumors.com/threads/macos-10-14-mojave-on-unsupported-macs-thread.2121473/page-199
Or at least help me to increase my HD 3000 VRAM to at least 1GB?
Thank you!
sudo mount -uw / ; killall Finder
sudo chown -R 0:0 /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo kextcache -i /
(this will take a while to complete)
sudo reboot
I made pre-patched IntelHD3000 gpu kext with any VRAM increase combinations, you can use the zip package uploaded here:
IntelHD3000 VRAM increase pre-patched HighSierra/Mojave/Catalina
they are already tested to work with HighSierra, Mojave and Catalina.
Before replace the patched files, open a Terminal and run this:sudo mount -uw / ; killall Finder
After you replaced the patched files, open Terminal and copy/paste this one line at once:
Code:sudo chown -R 0:0 /System/Library/Extensions sudo chmod -R 755 /System/Library/Extensions sudo kextcache -i / (this will take a while to complete) sudo reboot
Tried this on a 13" 2011. But it says read-only file system...
Apfs and sip disabled, Catalina.
Single User Mode same result.
What to do?
sudo mount -uw / ; killall Finder
