Description of problem:

For the client, the MacOS system occupies a certain proportion. In order to improve the comprehensiveness of the product, Operator has provided the corresponding client of the MacOS amd64 version https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/operator-sdk/pre-release/

and the arm64 version https://github.com/openshift/ocp-release-operator-sdk/pull/286

 The latest MacOS systems are being built with the ARM architecture.

ART team will publish arm64 darwin version for OperatorSDK https://issues.redhat.com/browse/ART-6527

So suggests adding the client documentation for the MacOS system
(amd64 and arm64)

Suggestions for improvement: 

1, You can install the OpenShift SDK CLI tool on Linux or Mac.

download the latest version of the tarball for Linux.

and some other places

 
2, Procedure # Navigate to the OpenShift mirror site.
