Chromebook Setup Options

Option 1: Stay in Chrome OS

If you're writing bare-bones javascript for the browser, creating Chrome Apps and Extensions, or using remote coding apps like cloud9, Koding, or Nitrous, you may not need to install Ubuntu. Some tutorials can be done entirely within the browser. The tradeoff is that you won't have a full-featured command line, and you may hit a point where you can't install something that you need.

To start coding within Chrome OS, install Text or Caret as a text editor. (Text stores files in Google Docs and Caret stores the files locally on your machine, which may help you choose.) After that, you're good to go, since Chromebooks come with a browser installed.

crosh> help

 enterprise_ca_approve [--allow-self-signed] <url>
  Approve an enterprise certificate authority.  The <url> option should be
  an http or https url to your enterprise Certificate Authority in PEM
  format.  This CA will be used to validate the signature of an enterprise
  policy extension.

  If the --allow-self-signed option is provided, then you may provide a self
  signed CA.  Use this only if you are certain of the source of the CA.

macOS Server discontinues calendar and contacts services.

https://support.apple.com/en-us/HT208312

Prepare for changes to macOS Server 5.7.1

As hosted services have become widespread—and the need to keep software up to date is more important than ever—Apple is making some changes to macOS Server.

Learn about current and future support

Apple continues to develop and support macOS Server, which includes Open Directory, Profile Manager, and Xsan management. The most popular server features—Caching Server, File Sharing Server, and Time Machine Server—have been bundled with every installation of macOS High Sierra since its release in fall 2017, so that even more customers have access to these essential services at no extra cost. >
