Apple Business Manager in 2026: What's Changed and What Still Trips Teams Up

ABM and MDM have matured significantly, but the setup mistakes I see most often are still the same ones from three years ago. Here's a practical rundown of what's actually new, what isn't, and where small teams still get stuck.

What's actually new in 2026

Apple has shipped meaningful improvements to the ABM and Apple Push Notification Service experience over the last two years — declarative device management is now the default for new deployments, the federated authentication story with Microsoft Entra and Google Workspace is finally ergonomic, and the device-prep flow is far less brittle than it used to be. If you set up ABM in 2022 and haven't looked at it since, it's worth a fresh visit.

Mistake #1: Treating Apple Business Manager as optional

Every couple of months I'll talk to a small team that bought ten MacBooks from a local reseller and started enrolling them by hand. ABM is free, it takes about an hour to set up properly, and it's the foundation for every Apple-fleet workflow you'll ever build. Skipping it doesn't save time — it just defers the cost to the moment you finally have to migrate.

Mistake #2: One Managed Apple ID per shared device

Managed Apple IDs are per person, not per device. Sharing a single ID across a team breaks iCloud sync expectations, undermines the audit trail, and creates a brittle credential everyone on staff knows. Federated auth eliminates this entirely if you're on Entra or Google — use it.

Mistake #3: Picking an MDM and never revisiting it

The MDM landscape has shifted. Jamf, Kandji, Mosyle, Addigy, Hexnode, and Microsoft Intune all behave differently for fleets under 50 devices than they do at enterprise scale. The right choice in 2022 may not be the right choice in 2026 — particularly on price and on how well the vendor handles declarative management.

Mistake #4: Not enrolling existing devices

ABM only auto-enrolls devices purchased through ABM-linked resellers after you set it up. Existing devices need to be enrolled manually or wiped and re-enrolled. There's no shortcut, and skipping this step leaves you with a two-tier fleet you'll regret a year later.
