Is Metal used by OSX 10.11 for rendering?

In short, looks like OSX 10.11 doesn’t use Metal to render anything.

Update: Metal seems to be used for gui on Intel graphics.

Metal supported GPU

This info comes from metal driver availability, not from real test

Metal supported card families:

Nvidia – GeForce gtx 4xx and newer
Intel – HD4000 and newer (ivy bridge and newer)
AMD – HD7000 and newer

Some apps to test metal support -= Metal.zip

MetalInfo to show some (very minimal) device Information and MetalTest – simple 3d box rendered with Metal

Example of MetalInfo output:

MetalInfo!
Metal Device Name: NVIDIA GeForce GTX 670
Lower Power Device: No
Headless Device: Yes

kext-dev-mode still works

Nvidia driver is….. still 310.42.05a43 , no love for maxwell

New root-less security is based on sandboxing shell and its commands, so you can’t edit system files even if you a root and file has 755 mode

files are editable if you boot yosemite

To disable rootless mode set boot argument rootless=0

You can still set boot-args with sudo nvram even in rootless mode.

No Metal for pre-Fermi nvidia cards

OpenGL still at level 4.1
