 ## NOTE
 
 - The [Extended Virtual Addressing](https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_kernel_extended-virtual-addressing) capability is recommended to enable on iOS project.
-- Currently we got some iOS devices crash by enable Metal ('options.gpuLayers > 1'), to avoid this problem, we're recommended to check [Metal 3 supported devices](https://support.apple.com/en-us/HT205073). But currently the cause is still unclear and we are giving this issue a low priority.

 - We can use the ggml tensor allocor (See [llama.cpp#2411](https://github.com/ggerganov/llama.cpp/pull/2411)) by use `RNLLAMA_DISABLE_METAL=1` env on pod install, which reduces the memory usage. If you only want to use CPU, this is very useful.
