This page is an active list of known issues affecting Photo Mechanic and Photo Mechanic Plus users. Not all issues are necessarily posted here, but we'll make our best effort to update this page in a timely manner. Workarounds will be posted if one is known of.
- Photo Mechanic Plus build 7285 and lower on MacOS Tahoe 26.0 and later
- Elements of Photo Mechanic's Catalog interface do not scale correctly on MacOS Tahoe. As this version is now end-of-life and no longer receiving updates, it will remain an issue on MacOS Tahoe unless Apple fixes whatever what was changed in Tahoe that is causing the issue. Any subscription license or perpetual license purchased after March 12, 2024 can activate a build that will not experience this issue. Contact Camera Bits Support to inquire about upgrade discounts.

- MacOS Tahoe Only: Some text fields have a transparent background, making entered text difficult to read.
- Photo Mechanic Plus Only: MacOS Sonoma 14.3 breaks critical catalog functionality
- Please see forum post for updates: https://forums.camerabits.com/index.php?topic=16020.0
- HEIF/HEIC rendering times on Contact Sheets/Preview window
- We are investigating how to improve performance when rendering these files
- Preloading Metadata stalls
- When attempting to do an operation on a large number of items, a progress window will appear indicating that Photo Mechanic is working on Pre-loading Metadata. If the progress bar stalls, cancel the operation and try again and it should get further next time. Repeat until the progress bar completes, at which point it should continue with the operation. Alternatively, scroll to the bottom of the Contact Sheet and wait for all thumbnails to load, and then perform the operation.
- MacOS Only: Slideshow shows a black screen when started, requiring a force quit
- Restore Photo Mechanic to it's default preferences. Contact Camera Bits Technical Support for assistance.
- Slideshow is not color managed
- No known workaround
- System clock changes can interfere with Incremental Ingest
