Is there any similar solution to enable this option for 8gb Macs?

I suppose it is optional like TPM in windows

Great idea! I'll take a look at that.

Have you tried this?

defaults write -app Xcode IDEModelAccessOnDeviceAvailabilityOverride ready

Update: this will only affect Xcode settings UI and won't make Xcode LLM run. I'm still investigating how to patch.

👀 I'm looking forward to it!

We can attach to Xcode:

lldb /Applications/Xcode-beta.app

then set a breakpoint to ASI_PhysicalMemorySize:

b ASI_PhysicalMemorySize

each time the lldb hits the breakpoint, make it return a number higher than 16000000000:

thread return 17179869184

and then continue:

continue

Although these steps can let you turn on the switch on settings and download the model, XcodeLLM seems not working. While trying to type code, lldb console always print these messages:

Hi.

Since Xcode 16 Beta 4, Predictive Code Completion is available for 8GB Macs.

https://developer.apple.com/documentation/xcode-release-notes/xcode-16-release-notes

For China SKU Macs, a hack is still needed.

@WindowsMEMZ I believe that ASI_PhysicalMemorySize only affects Xcode settings GUI, and there is actually another routine to determine memory size inside the system private framework ModelCatalog that invokes MobileGestalt_get_deviceMemorySize. But on my machine (16GB memory) this routine never runs, and I am stuck here.
