Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Gotten from the RedHat GPG migration manual

Backup the public and secret keyrings and trust database

## Export all public keys

gpg -a --export >mypubkeys.asc

// This shows an example of how to generate a SSH RSA Private/Public key pair and save it locally

package main

import (
	"crypto/rand"
	"crypto/rsa"
	"crypto/x509"
	"encoding/pem"
	"golang.org/x/crypto/ssh"

Once you have ordered DEV Admin Storage, ssh to bastion and run the following

oc set env deploymentconfigs.apps.openshift.io admin -n labguide -e DOWNLOAD_URL=https://raw.githubusercontent.com/openshift/openshift-cns-testdrive/ocp4-dev/labguide

Check status with

oc rollout status dc/admin -n labguide
