Resolution Configuration

[cezar-pimentel]

Hello everyone!

I'm trying to set a different resolution to the VM, and I followed the steps on creating a new entry to the "dist\EFI\OC\Kexts\MacHyperVFramebuffer.kext\Contents\Info.plist" file.

This is how it looks like:
<dict> <key>HyperVGraphicsFramebuffer</key> <dict> <key>CFBundleIdentifier</key> <string>fish.goldfish64.MacHyperVFramebuffer</string> <key>IOClass</key> <string>HyperVGraphicsFramebuffer</string> <key>IOMatchCategory</key> <string>IOFramebuffer</string> <key>IOPCIMatch</key> <string>0x53531414</string> <key>IOProbeScore</key> <integer>50000</integer> <key>IOProviderClass</key> <string>IOPCIDevice</string> <key>SupportedResolutions</key> <array> <dict> <key>Height</key> <integer>480</integer> <key>Width</key> <integer>640</integer> </dict> <dict> <key>Height</key> <integer>600</integer> <key>Width</key> <integer>800</integer> </dict> <dict> <key>Height</key> <integer>768</integer> <key>Width</key> <integer>1024</integer> </dict> <dict> <key>Height</key> <integer>864</integer> <key>Width</key> <integer>1152</integer> </dict> <dict> <key>Height</key> <integer>720</integer> <key>Width</key> <integer>1280</integer> </dict> <dict> <key>Height</key> <integer>1024</integer> <key>Width</key> <integer>1280</integer> </dict> <dict> <key>Height</key> <integer>1400</integer> <key>Width</key> <integer>2560</integer> </dict> </array> </dict> </dict>

Is this correct, or should I remove the other entries and only leave the 2560 x 1440 I added?

Edit: I tried I bunch of things (like adding a new entry, and overwritting the 1024 and 768 entries with the desired resolution, and then I recreated the VM and reinstalled the OS, but still, the only resolution I get is still 1024x768.

What exactly needs to be done in order to enforce a different resolution?

Thanks!

This is correct, though I'd note that there are some limitations to the resolutions you can actually select due to VRAM limitations. That's a known limitation that you can find more discussion in #69 as well as a current workaround.

That kext won't work from the EFI folder/virtual disk, but you can run a post-install script to install it to /Library/Extensions/ where it'll work.

The EFI virtual disk created by this project bundles a post-installation script responsible for installing the MacHyperVFramebuffer driver and configuring daemons for additional Hyper-V service support. This is required to support resolution changes and the hardware cursor in macOS.

To run this script, execute the post-install.sh script from the EFI disk located in the Scripts/ directory. For example, you can run the following command in Terminal after booting into the macOS installer:

cd /Volumes/EFI # Change to the EFI disk
bash ./Scripts/post-install.sh

You can also optionally run the optimize-vm.sh script to disable Spotlight indexing, reduce disk I/O, and turn off system animations. This is recommended for virtual machines with CPU-rendered graphics and limited disk performance.

cd /Volumes/EFI # Change to the EFI disk
bash ./Scripts/optimize-vm.sh

Thanks for taking the time to respond. I really appreciate it!
Alright! This is looking fantastic at 5120 x 1440! Thanks for all the explanation!

Nice job putting all this together, this is not an easy project and you're doing a great job!
