I’ve encountered a critical issue in macOS Tahoe (Beta) that affects the Photos app or any app that leverages Apple’s editing frameworks. After editing certain photos—whether applying filters, cropping, or making basic adjustments—the image suddenly turns completely black upon saving or exiting the edit mode.
Details:
macOS Version: macOS Tahoe (latest beta)
Affected App(s): Photos, Preview, and some third-party editing apps
Steps to Reproduce:
Open a photo in the Photos app
Make any basic edit (e.g., crop, adjust brightness)
Click “Done”
The edited photo appears entirely black
Notes:
Happens with both JPEG and HEIC formats
Original photo appears fine before editing
Exporting the photo also results in a black image
Restarting the app/system does not resolve the issue
iCloud Photos is enabled
This issue seems related to the image rendering pipeline post-editing, possibly tied to Core Image or GPU rendering frameworks. It severely affects photo usability and could result in permanent data loss if backups are not maintained.
Please advise if a workaround exists or if this bug has been logged already. Happy to provide system logs or sample images if needed.
Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. Please file a bug report, include a small Xcode project and some directions that can be used to reproduce the problem, and post the Feedback number here once you do. If you post the Feedback number here I'll check the status next time I do a sweep of forums posts where I've suggested bug reports.
