Local SSL websites on Mac OS X Yosemite

Local SSL websites on Mac OSX

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on Mac OSX Yosemite.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward edit to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

Provisioning profiles

find . -name '*.mobileprovision' -print0 | xargs -0 -t -n 1 security cms -D -i | grep -A1 UUID 2>&1

Convert .mobileprovision to .plist

security cms -D -i foo.mobileprovision -o foo.plist

Extract signing certificate from provisioning profile plist

Download and view old Apple developer documentation

How to download and view legacy documentation from Apple (no need to sign in to your dev account).

  1. Go to https://developer.apple.com/library/downloads/docset-index.dvtdownloadableindex
  2. Find the docset you want (there are some with URL https://apple.com/none.dmg; ignore them - you will find them again further down the file with a working URL).
  3. Download the dmg. It's probably around a gigabyte or so.
  4. "Install" the .pkg file somewhere on your disk. If you don't trust the installer, do it manually:
    1. Find the largest file, names Payload, and extract it using The Unarchiver.
    2. This created a new, even larger file, probably named Payload-1.
    3. Extract Payload-1 using The Unarchiver.
  5. After many minutes of extracting, we have our .docset file.
