Managing Apple Devices: Deploying and Maintaining iOS 8 and OS X Yosemite Devices, 2nd Edition

OS X Server for Yosemite (also informally known as Yosemite Server) helps your users collaborate, communicate, share information, and access the resources they need to get their work done. While OS X Server indeed provides a variety of services, the aim of this guide is to focus on the services that facilitate the management of Apple devices.

This lesson begins with a brief introduction of OS X Server before moving into the requirements and initial setup of OS X Server. This lesson also covers selecting and configuring Secure Sockets Layer (SSL) certificates required for Apple device management.

Other solutions are capable of providing management for Apple devices, but at only $19.99 (US), none of them is as inexpensive as OS X Server. Also, despite the price, because Apple develops OS X Server, it’s often the first management solution that supports the latest Apple management features and operating systems.

Further, even if you intend to use a third-party Mobile Device Management (MDM) solution, other services in OS X Server are still clearly the best solution. For example, the Caching service has no alternative if you want to reduce the Internet bandwidth required for installing and updating Apple-sourced software. Also, other services in OS X Server are simply the best implementation available. The NetInstall service that provides network system disk access for OS X computers is available from other servers, but the implementation in OS X Server is considered the best choice.

Services Covered in This Guide

Again, this guide focuses on the OS X services that are most responsible for helping administrators manage their Apple deployments:

  • Caching service—As introduced previously, the Caching service greatly reduces Internet bandwidth used for the installation of Apple-sourced software and media. Lesson 5, “Caching Service,” focuses on the architecture, setup, and troubleshooting of this service.

  • Profile Manager—This is the name given to the MDM service provided by OS X Server. The vast majority of material in this guide deals directly with or is designed around MDM management workflows. Both Lesson 6, “Configuration and Profiles,” and Lesson 7, “Mobile Device Management,” cover Profile Manager specifically. In addition, nearly all lessons that follow these two deal with topics related to MDM services.
  • NetInstall—This service makes OS X systems available for startup via a network connection. NetInstall is often used as a platform for installing or re-imaging Mac computers en masse. Coverage of this service is beyond the scope of this guide, but you can find out more from Apple Pro Training Series: OS X Server Essentials 10.10, also from Peachpit Press.
  • WebDAV—This is the only local file-sharing service provided by OS X Server that supports both iOS and OS X devices. This is covered as part of Lesson 16, “User Data and Services.”
  • Wiki—The OS X Server Wiki service not only provides a browser-based interface for collaborative document creation but also serves as an alternative for local file sharing. This service is also covered as part of Lesson 16, “User Data and Services.”

If it ain’t broke, don’t fix it is a rule that Apple may wish it had heeded when it released Yosemite back in 2014. Why? Because Apple’s famed ‘it just works’ ease of use took a serious hit, at least when it came to networking. When it launched Yosemite, Apple ditched a process called ‘mDNSResponder’, which was a key part of Bonjour, the auto-discovery system for devices on a network. Without mDNSResponder, Bonjour ran into a heap of trouble on lots of Macs. And it wasn’t long before users started complaining of bugs in the system.

What is mDNSResponder and why is it on my Mac?

As many users discovered when they installed Yosemite, mDNSResponder is a critical part of the Bonjour networking protocol. Bonjour is the thing that allows your Mac to ‘see’ other devices like computers, printers, and storage devices on your local network and connect to them easily. If you’ve ever noticed a printer or computer in the sidebar in the Finder that just appeared there, that’s Bonjour — it ‘discovered’ it on your local network and allowed you to see it so you can connect if you want. Noticed an app pop-up on the Dock on your Mac when you use it on an iPhone or iPad close by? That’s Bonjour too. And mDNSResponder is key to Bonjour working properly.

Specifically, mDNSResponder is a daemon that’s responsible for discovering services running on other devices on the local network. It also handles DNS requests for services that need to connect to the internet. Apple replaced it with a service called ‘discoveryd’ process in Yosemite and things went badly wrong — perhaps no surprise given than mDNSResponder had been fine-tuned for over a decade and that networking has always been one of the most troublesome parts of macOS.

Did you know?

Ars Technica reported that when Apple put mDNSResponder back into macOS, it was able to close 300 separate bug reports. That shows you just how much an effect removing it had on macOS and demonstrates that even Apple gets it wrong sometimes.

What’s the problem with mDNSResponder?

Some Mac users have reported that mDNSResponder’s network usage is causing problems on their Mac, and that it’s flooding the network with ‘junk packets’ — traffic that occupies bandwidth but serves no purpose. They discover this using tools that monitor network traffic. For that reason, they want to remove or disable it.

However, removing mDNSResponder will break Bonjour and make discovering and connecting to other devices on the network impossible. You could disable Bonjour altogether, but that would mean manually entering details for every device you want to connect to and make any services that rely on auto-discovery, like Hand-off and Continuity, unusable.

Tip: If you face any issues or see alerts about the mDNSResponder, flush your DNS cache with a free tool in CleanMyMac X. It helps resolve some server connection problems.

After you install the app, click Maintenance and tick Flush DNS Cache.
If you’ve noticed that your Mac has become sluggish, it can be difficult to work out what the problem is. You could use Activity Monitor to identify mDNSResponder, but all those processes are difficult to understand. CleanMyMac X can help.

CleanMyMac X has a menu item that you can keep active even when you quit the main app. It allows you to monitor CPU usage, network activity, and free up memory. You can get more information on resource hogs within the menu item, and also quit apps that are too demanding.


The main CleanMyMac X application has an optimization tool that also highlights heavy consumers of resources, allowing you to take control of them. And it can identify and shut down applications that have stopped responding due to a problem.


As you can see mDNSResponder isn’t a virus, as some people think when they see it running in the background. It’s an essential component of macOS that allows the automatic discovery of devices on the local network in Bonjour. So you should definitely not try and remove it. If you think it’s making your Mac slow, there’s probably another explanation. And to find out what it is, you can use CleanMyMac X’s arsenal of tools. Once you’ve identified the problem, CleanMyMac can help you solve it by freeing up RAM or quitting hung processes.
