Apple’s macOS 27.2 release candidate notes say Macs with a clean install of the build might not prompt you to allow notifications for some apps, including Calendar, Maps, Find My, Home and Weather. Apple also lists a second known issue where display settings might not be restored correctly when an external display is connected, and the display arrangement might change.
Both items appear in the macOS 27.2 release notes, which cover the macOS 27.2 Golden Gate RC. Release candidate notes describe the build closest to the final macOS 27.2 release, so they are a useful guide to what Mac owners might run into once it arrives.
Missing notification prompts after a clean install
Apple’s wording for the first issue (187312007) is that “Mac computers with a clean install of this build might not prompt you to allow notifications for some apps, such as Calendar, Maps, Find My, Home, and Weather.”

The key words are clean install. If you erase a Mac and install this build fresh, or set up a new Mac on it, some of Apple’s own apps might never ask for notification permission. Because they never ask, their alerts can stay off without you noticing. Calendar reminders and Find My alerts are the kind of thing you only miss when it matters.
Apple names five apps as examples:
- Calendar
- Maps
- Find My
- Home
- Weather
Apple says “such as”, so the list is not necessarily complete. If another app that normally asks for notification access stays quiet on a freshly set up Mac, the same workaround should be your first check.
How to turn notifications on manually
Apple’s workaround is to go to System Settings > Notifications and turn on notifications for the affected apps yourself. Step by step:
- Open System Settings from the Apple menu.
- Click Notifications in the sidebar.
- Find the app in the list, for example Calendar.
- Click it and turn its notifications on.
- Repeat for Maps, Find My, Home, Weather and any other app that should alert you.
External display arrangement might change
The second known issue (188643179) affects Macs with an external display. Apple says that “when an external display is connected, display settings might not be restored correctly, and the display arrangement might change.”
In practice, that can mean your external monitor no longer sits on the side you set, or settings you picked for it are not where you left them. Apple does not list a workaround for this one. If it happens, open System Settings > Displays and check the arrangement and settings for each screen.
Other notes in the macOS 27.2 RC
The remaining entries are mostly for developers:
- Shortcuts: Describe a Shortcut might fail with the error “Something went wrong. Try again later.” (187499433)
- General: Apple fixed an issue where Xcode might crash when using code completion on macOS 27.2 beta (186939138). We covered that crash and its workaround in our earlier Xcode 27.2 report.
- AppKit: the EnablePasteboardPrivacyDeveloperPreview user default has been removed (186955507).
- StoreKit Testing in Xcode: three fixes for SKTestSession, covering intro offer eligibility after clearTransactions(), storefront and locale changes not reaching Storefront.updates, and error dialogs appearing when dialogsDisabled is set to true.
- StoreKit known issue: buying a subscription that belongs to a subscription bundle in an app incorrectly lets the user unbundle instead of throwing an error (186018916).
Who should care
If you upgrade an existing Mac in place, the notification issue as Apple describes it does not apply, since it is tied to a clean install. It matters most if you are setting up a new Mac, erasing one to start over, or testing on a fresh partition.
The display issue is broader. Anyone who uses an external monitor with a Mac on this build could see their arrangement shift, so it is worth a quick look at System Settings > Displays after updating.
Apple has not given a release date for macOS 27.2. Until it ships, these two known issues are the ones most likely to reach everyday Mac users, and the notification one has a simple manual fix.
