Expected behavior

Docker beta should start and run

Actual behavior

Docker beta complains about incompatible CPU

Information

I have a MacPro with a Quad-core Intel. I can run the released docker, vbox, vmware, etc. All apps that require a processor with virtualization capabilities.

Beta stops with a Fatal Error

Same issue here for a Mac mini (Mid 2010) / Macmini4,1 / MM41.0042.B03 (EFI 1.5)
2,4 GHz Intel Core 2 Duo

OS X: version 10.11.5 (build: 15F34)
Docker.app: version v1.11.1-beta12

vmware fusion is running on same machine, so virtualisation is possible?

The same version docker beta app runs fine on my macbook air: 2 GHz Intel Core i7.

Found this: Fatal Error Incompatible CPU detected
"sysctl kern.hv_support" is 1 on my macbook air and 0 on the mac mini, guess it will not work when it is 0.

From the Apple Docs:

Supported Hardware

Generally, machines with an Intel VT-x feature set that includes Extended
Page Tables (EPT) and Unrestricted Mode are supported. You can determine
the availability of Hypervisor APIs on a particular machine at runtime with
the sysctl(8) command, passing kern.hv_support as an argument.
