Confused? Read Using Reposado to manage cached Mac updates yet? If not, read that first.
There's a great step-by-step guide to setting up Reposado on Ubuntu Linux, and, in fact, one of the benefits of Reposado is that it can be run on Linux... but it doesn't have to be. For whatever reasons you have, you may want to run it on a Mac instead.
First, make sure Apache is up and running on your Mac:
sudo apachectl start
and then visit localhost
in a web browser on your machine or https://myserver.mycompany.com
from another computer (with your actual Mac-as-web-server's fully qualified domain name in place of the dummy placeholder I gave as an example).
You may have to configure a bunch of other things on the web server for that last part to work—all that's a bit outside the scope of a Reposado tutorial.
(Keep in mind, too, that the path I'm using to the web server documents is based on a regular macOS installation. If you add OS X Server on top of that, the path then changes to /Library/Server/Web/Data/Sites/Default.)
Next, get the latest Reposado code. If you have Git installed, you can just clone the repository:
git clone https://github.com/wdas/reposado
If you don't have Git installed and don't want to install it, you can also click the Clone or download link on the Reposado GitHub repository and then double-click the downloaded .zip to unzip its contents.
Either way, you should have a folder called reposado with a subfolder called code.
Go ahead and copy that to /usr/local/reposado:
sudo mkdir -p /usr/local/reposado
sudo cp -R /PATH/TO/reposado/code/* /usr/local/reposado/
Make folders to store the Reposado-downloaded Apple updates data:
sudo mkdir -p /Library/WebServer/Documents/reposado/html
sudo mkdir -p /Library/WebServer/Documents/reposado/metadata
sudo /usr/local/reposado/repoutil --configure
You'll be asked a few questions. Answer them appropriately. If you drag the folders to the terminal, be sure to delete any trailing spaces.
Filesystem path to store replicated catalogs and updates [None]:
Filesystem path to store Reposado metadata [None]:
Base URL for your local Software Update Service
(Example: http://su.your.org -- leave empty if you are not replicating updates) [None]:
Create at least one branch (you'll probably have at least two later):
sudo /usr/local/reposado/repoutil --new-branch testing

Start syncing your Reposado cache with Apple's update servers:
Note: This could take a while (depending on your bandwidth) and download several hundred gigabytes of data.
Once it's finished syncing up, add all the products to the testing branch:
repoutil --add-product all testing
Now, you should be able to see the catalog if you visit
That URL will change with each new version of macOS that's released (the sample above is valid as of Sierra), so you may want to wait until Reposado's code is updated and then do another Git clone on the code to update the URL (and then fix the URL for your clients).
The last part of the URL is the branch you want the client to access (in this case, testing).
To write the change to a client, run on the client machine:
sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL "https://myserver.mycompany.com/reposado/content/catalogs/others/index-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1_testing.sucatalog"
That's a very basic setup. For more details on Reposado options, read the official docs.
