Under-the-hood AI changes and efficiency improvements at the OS layer across Apple’s platforms are certainly the highlights at WWDC 2026. But there have also been significant changes IT admins will need to prepare for, particularly around Declarative Device Management (DDM). 

The Intel age is over

Apple warned us this was coming, but macOS 27 will not support Intel at all. The company will deliver three more years of security updates for those devices, and you will still be able to use Rosetta to get Intel app binaries to run legacy apps on Apple Silicon. But if you still rely on any Intel apps or Macs, it really is time to plan your upgrade.

DDM becomes the present

It was the future once, but when it comes to Declarative Device Management (DDM) that future is now. Apple is removing all its legacy MDM mechanisms to replace them with DDM. “For IT admins, WWDC 2026 is a migration year,” wrote Fleet. “Apple is removing legacy MDM mechanisms and replacing them with Declarative Device Management (DDM). Some of it is urgent. Some of it just needs a plan.”

It’s a great step, though IT admins will need to ensure they aren’t relying on legacy MDM to handle any of their device fleets. That’s a particular issue around software and security update management. In most cases, your MDM provider has probably already introduced DDM support. But if you aren’t certain, now is the time to find out before your systems fail.

Apple has also added new DDM tools across various systems, apps, identities and more. Some of the highlights include:

• VPN and Network configurations can be provisioned using DDM; they also become credential-reliant, which should make management more streamlined.
• Apple Intelligence, Siri, and keyboard settings can also be configured via DDM, and admins can manage individual Apple Intelligence tools. 
• Web content filter and content caching both become controllable with DDM.
• A new privacy key lets IT manage things like camera or microphone access.
• Apple has added a device system health reporting function to verify that hardware components on iPhone and iPad are genuine.
• IT will be able to detect whether a device is in Lockdown Mode.

“One of the new features I’m most excited about is the ability to set permission defaults for managed apps and websites viewed in Safari,” said Adam Henry, senior product manager at Iru. “While the user is still prompted to allow these permissions, we can now present those requests as a unified prompt immediately upon app launch, along with a custom explanation as to why those permissions are important — think a teleconferencing app or website that always needs access to camera and microphone.

“Overall, I think this is a much more user-friendly solution that will likely increase permission compliance.”

Siri and AI

Although, Apple has introduced new management tools for AI, it’s important to remember some advice from Joel Rennich, senior vice president for product management at JumpCloud: “Traditional IAM models assume users directly interact with applications, but agentic systems change that assumption. AI intermediaries can now retrieve data, execute workflows, and make decisions across systems. Enterprises will need identity frameworks that govern both human and non-human actors consistently.”

He also noted: “The separation between where data lives and where it is used becomes increasingly invisible to the user. Intent becomes the primary input, not app selection.”

At the same time, the evolution of AI on Apple’s devices promises a lot for enterprise users. Matt Vlasach, Jamf senior vice president, enterprise products and solutions engineering, told me: “Most notable for me was Siri AI and the push towards on-device and more capable models that can do more with user context. While obvious for consumer use cases as illustrated in the keynote, the opportunity to evolve this to the work context using a more advanced Apple Intelligence framework is an exciting evolution.”

Farewell AFP

Apple has finally eradicated Apple Filing Protocol (AFP) in macOS. This will be an issue for any business that uses legacy Time Capsule or NAS storage devices, though in most cases those products are already obsolete and should be replaced. This is unlikely to be a huge challenge for most, given that Apple began using SMB as its primary file sharing protocol back in 2013 and support for AFP server disappeared in 2020. (Time Capsule fans might want to take a look at the TimeCapsuleSMB open-source project.)

Hello AppleCare log collection

Apple will introduce a new remote log collection capability that integrates directly with the company’s support infrastructure. So, when AppleCare support engages with an organization’s IT team, they can provide an enhanced logging token which can be shared to get the device to collect diagnostic logs to upload to AppleCare. You just know this will expedite remedy.

Single Sign-On improvements

As I noted here, there are some significant Single Sign-On (SSO) updates; two that caught my eye include:

• IT can now insist on biometric as well as password ID on managed devices.
• Authenticated Guest Mode with Platform SSO allows users to quickly and securely login to a shared Mac in a temporary session.
• Platform SSO on macOS 27 adds web-based authentication.

Network and more

Another change affects the system processes used in device management at a network level. Apple now requires that you use TLS 1.2 or later. If you or your MDM systems are not doing so, get ready for things to break. (Apple has published a support article to help IT test their network environments in preparation for this change.)

Apple also announced that IT admins will be able to purchase and manage app subscriptions directly in Apple School Manager and Apple Business Manager. And it introduced a managed migration feature that should help migrate data, while preserving device management enrollment and settings. 

More information

I’ve really only offered a flavor of some of the IT improvements introduced at WWDC. To find out more, watch the Apple sessions on “What’s new in managing Apple devices” and take a look at the Apple Platform Deployment guide; it should be updated before the new operating systems ship this fall
