We've noticed some users experiencing thumbnail display problems with PSD files and other formats after upgrading to macOS Sequoia (15.0). These issues include missing thumbnails, abnormal displays, or preview failures. We understand this impacts your workflow and apologize for any inconvenience.

Cause of the Issue

Our engineering team has discovered that macOS 15 introduced significant changes to file thumbnail-related APIs. Apple has removed support for the older Quick Look Generator plugin, replacing it with new APIs and extensions. This system-level change has affected Eagle's ability to properly generate thumbnails for certain file types.

Solution

We've implemented fixes in our latest release to address these compatibility issues:

Update Eagle: Install Eagle 4.0 build 4 or later from our official download page
Refresh affected thumbnails: Right-click on files with abnormal thumbnails → "More" → "Refresh Thumbnail"

Important Notes

The preview quality when double-clicking files may be reduced compared to previous versions due to our temporary workarounds
This issue affects many applications beyond Eagle, including Affinity products (Photo, Designer)
If certain file formats cannot be previewed using the spacebar in Finder, Eagle's preview functionality for those formats may also be affected
Full preview functionality will be restored as third-party software vendors update their applications for macOS Sequoia compatibility
