WWDC22: Apple brings declarative machine administration to the Mac?
Apple first launched declarative machine administration for MDM methods managing iPads and iPhones at WWDC in 2021.
More alternatives for engineers and builders to implement declarative machine administration options are more likely to emerge at WWDC 2022, not less than, in response to MacAdmins.
Speaking throughout the pre-event podcast, audio system argue that Apple will finally require that each one cellular machine administration (MDM) suppliers introduce assist for declarative administration. Might this embrace bringing declarative machine administration to the Mac?
What is declarative machine administration?
Apple first launched declarative machine administration final yr, largely for 2 causes: to make units extra proactive, and to cut back the impression on MDM servers that deal with massive fleets of units. This ought to increase efficiency and scalability.
“By sending declarations to the device and utilizing the status channel, that device becomes more autonomous and proactive. And your MDM solution will manage many facets of the device experience using the MDM protocol,” Apple’s developer notes clarify.
The distinction between customary MDM and declarative might be seen as follows:
Standard MDM:
When the MDM sends a command to the machine, a number of interactions between the server and the machine are wanted to implement the change. Alternatively, the MDM system has to ask the machine to replace it on any modifications made on the machine finish. The machine doesn’t monitor itself for necessary modifications, and won’t proactively contact the MDM system to let it know such modifications have taken place.
Declarative:
Devices monitor themselves and might notify an MDM system when a change is utilized. They may deploy modifications extra swiftly with much less interplay between the server and the machine. In half, this autonomy additionally offers the machine higher safety when it’s offline, or when the MDM server is unavailable. In impact, insurance policies might be utilized extra swiftly and admins profit from extra correct data regarding units within the fleet.
How has Apple constructed its Declarative Device Management system?
At WWDC 2021, Apple launched the primary model of its Declarative Device Management protocol. This depends on Declarations, Status Channel, and Extensibility.
What is a Declaration?
A Declaration is mainly a coverage resolution given to the machine. That might be for account settings or entry to enterprise companies, however may also be utilized at a consumer or machine degree. You would possibly ship comparable privileges to all of your customers, however assign particular people administrator rights from their machine(s), for instance.

Declarations can embrace machine configuration, belongings (corresponding to usernames and certificates) and activations — insurance policies which can be utilized to the machine. Once a tool has pulled all of the declarations accessible to it from the MDM server, it should start to use any coverage modifications required to work inside them.
What is Status Channel?
At its easiest, MDM engines use this to ballot units for necessary modifications, corresponding to requesting a notification if a tool upgrades its iOS model. This can then set off task of extra insurance policies to the machine related to that newly put in working system.
What is Extensibility?
One good instance of what extensibility means within the context of declarative machine administration might relate to a tool’s working system being upgraded. The machine can let the MDM server know an replace has taken place and the MDM can then assign a brand new coverage that permits a brand new characteristic that may not have been supported earlier than. An MDM may additionally have the ability to determine which units have been upgraded to deploy any options newly accessible.
Developers can watch a WWDC 2021 session on declarative machine administration right here.
How will Apple improve declarative machine administration?
We know Apple has already referred to as declarative machine administration the “way forward for machine administration,” which suggests the corporate will proceed to spend money on bettering its present system.
It additionally sends a really message to builders that they need to prioritize their assist for Apple’s system within the options they supply, or, within the case of purchasers, the MDM methods they select to make use of.
Apple’s first iteration supported iOS units, which itself implies the corporate intends on extending this to its different platforms, together with the Mac. Mac integration makes full sense, given Apple Business Essentials and the continued ascendance of Macs within the enterprise — however it does appear attainable the characteristic will solely be made accessible to Macs working an M-series Apple Silicon chip.
We’ll be watching WWDC22 later at this time to search out out whether or not this seems to be the case. Check again right here later for all of the keynote highlights for enterprise IT.
