Mac bugs and fixes September 26 2026: no fix yet

What broke in OneDrive after macOS 27?

OneDrive lost its working sync location after the upgrade. Anthonyai said on September 23, 2026, that OneDrive had no Microsoft fix yet.

The same Anthonyai report, dated September 23, 2026, says OneDrive can display a missing OneDrive (2026-09-13 05:36:04 +0000) folder while the real folder remains under ~/Library/CloudStorage/. Try Again and Stop Sync do not resolve the dialog, while the menu-bar controls offer only Close OneDrive and Stop Sync. Anthonyai attributes the failure to File Provider registration that still points to a sync location that no longer exists.

Anthonyai said on September 23, 2026, that two users resolved the failure by replacing the App Store build with Microsoft’s standalone download, while reinstalling the App Store build did not help. OneDrive’s reset script also returned Operation not permitted errors on container folders. The workaround costs time for removal, installation and sign-in, and it changes the application’s distribution channel. I would first confirm that the real OneDrive folder remains under ~/Library/CloudStorage/, then install Microsoft’s standalone build without deleting local work.

Why did printing fail after the upgrade?

Printer software and some print paths lost compatibility with macOS 27. Printerbase Co said on September 23, 2026, that AirPrint was the safest option.

Printerbase Co reported on September 23, 2026, that some HP owners lost printing entirely, while other people could print normally except for one particular file type. The report says macOS 27 automatically removes Rosetta 2 during an upgrade unless an installed Intel application already needs it, which can leave an older printer utility or scanning tool unable to run.

Printerbase Co said on September 23, 2026, that a person can reinstall Rosetta 2 when an older printer or scanner tool requires it, and that option remains available until macOS 28 arrives in 2027. Printerbase Co called AirPrint the safest option right now, but did not identify a shipped repair for the affected vendor utility. No exact HP driver version, macOS point release or other shipped vendor update is named as a fix in the report.

Printerbase Co also said on September 23, 2026, that macOS 27 is exclusive to Apple Silicon and cannot be installed on an Intel Mac. I would verify the Mac’s chip in About This Mac before treating a printer failure as one of these Mac known issues.

Has a public macOS fix shipped?

No public macOS update fix is identified. Analyticsinsight said on September 22, 2026, that macOS 27.2 Beta 2 remained under testing.

Analyticsinsight reported on September 22, 2026, that the developer build is 26B5091g and that Apple’s release notes still list notification problems after a clean installation and an issue with Shortcuts’ Describe a Shortcut function. Those release notes do not establish that build 26B5091g repairs OneDrive File Provider registration or the reported printer failures.

Macobserver said on September 22, 2026, that build 26B5091g changes the volume and brightness overlays, but Apple has not promised that design will ship unchanged. Geeky Gadgets reported on September 22, 2026, that the beta still has a Spotlight-related Siri animation glitch, App Store subscription syncing trouble and notification failures in Apple applications after clean installations.

The cited reports do not identify an Apple security update or stable point release that repairs the current OneDrive and printer problems. For continuity, I would compare the affected machine with my previous Mac update status rather than treating beta availability as evidence of a shipped repair.

What can a person do today?

Wait for a public release on a work Mac. Macworld recommended caution with beta software on September 21, 2026.

For broken OneDrive sync, I would confirm that the working files remain under ~/Library/CloudStorage/, preserve a separate copy of unsynced work and replace the App Store build with Microsoft’s standalone download. Anthonyai said on September 23, 2026, that two users succeeded with that replacement, while reinstalling the App Store build and running the reset script did not clear the failure.

For printing, I would select AirPrint when the printer offers it, then reinstall Rosetta 2 only when an older printer or scanning utility needs Intel translation. Printerbase Co said on September 23, 2026, that AirPrint was the safest option and that Rosetta 2 can be installed manually when an older utility requires it.

I would not install macOS 27.2 Beta 2 merely to chase these macOS bugs, because Macworld warned on September 21, 2026, that beta software may introduce bugs, compatibility problems and poorer battery life. The honest status is limited: practical workarounds exist, but the cited reports name no stable point release that has taken either failure away.
