Zappl v3 introduces a completely redesigned user interface, rebuilt in SwiftUI to match AppBarâs look and theme. As part of this, the Zappl agent has migrated from a command line tool to a SwiftUI app, though it continues to support all the same command line options.Update prompts now display each pending update as an app card, alongside a new customisable info popover explaining the update and deferral process. The update progress prompt is smaller and more subtle, and the update completion prompt has been replaced by a native macOS notification. Self Service update prompts have also been deprecated - running
zappl -u selfService now redirects users to AppBar instead.A number of preferences have been deprecated, and several new ones added, including enableLiquidGlass, showInfoButton, initialPromptInfoPopover and gracePeriodPromptInfoPopover. Zappl v3 remains backwards compatible with existing configuration profiles - deprecated preferences are simply ignored, and new preferences retain their defaults until configured. If youâre a Jamf Pro customer, itâs recommended you update to the latest JSON schema. For all other MDMs, refer to the updated preferences documentation and sample plist.Because Zappl is now an app rather than a standalone binary, an updated PPPC profile and a new combined Zappl and AppBar Notifications profile are required - without these, users may see permission and notification prompts when Zappl runs. Both are available from our Deploy Anywhere guide. Jamf Pro customers using the Installation Status extension attribute should also update to the latest revision, which checks for the new app bundle path.For full details on everything thatâs changed, read the blog post.2026-06-19
Fix added for a bug introduced in 2.6.0 whereby, on clean installs, on-demand Self Service updates immediately after Zappl is installed do not override the scheduled background stagger check.Please note, Self Service updates are deprecated as of July 14th when Zappl v3 releases - more info.
2026-06-17
Added forward compatibility for the new Zappl v3 preferences to suppress errors caused by the changed preferences. The new schema will be released in the coming weeks, ahead of Zappl v3âs official release on Wednesday, July 1st. For more information on Zappl v3 - click here.

The download stagger window now applies to scheduled update prompts when background updates are disabled. The dependency between the two keys has also been removed, so
downloadStaggerWindow can be configured independently regardless of whether background updates are enabled.To better reflect this behaviour, the preference key has been renamed from backgroundUpdateWindow to downloadStaggerWindow.Additionally, the hourlyCheck preference key has been renamed to backgroundUpdates since background updates now operate on the stagger window rather than a fixed hourly interval.Both old keys are deprecated but will continue to work.If youâre a Jamf Pro customer, itâs recommended you update your Zappl preferences configuration profile to use the latest JSON schema. For all other MDMs, refer to the updated sample plist to see the new key labels in use.2026-04-23
