We would like to inform you of important information through this announcement: We currently do not recommend updating your macOS system to Sequoia (15.x) version. Recently, we have received extensive user feedback indicating that after upgrading to macOS Sequoia, users have encountered serious compatibility issues, mainly concentrated in the following two areas:

1. Serious Issues When Connecting to Local Networks, NAS, and Other Devices

In macOS Sequoia (15.x) version, Apple made significant adjustments to the SMB (Server Message Block) protocol implementation, causing users to experience serious problems when connecting to local networks, NAS, and other devices.

Problem Manifestations:

Through our in-depth investigation, the problems mainly manifest in the following aspects:

Network device access difficulties: Users may be unable to connect to or access network shared devices.
Data reading obstacles: Even when successfully connected, files or folders may not open or read normally.
Unexpected file loss: In some cases, files stored on network devices may mysteriously disappear.
Significant transmission speed decline: File transfer and data synchronization speeds may become abnormally slow.

These issues seriously affect users' daily operations and data management on local networks and NAS (Network Attached Storage) devices.

Temporary Solutions:

Use AFP protocol instead of SMB protocol: Switching to AFP protocol can temporarily resolve file loss and missing issues, but performance still cannot compare to macOS 14.
We are closely monitoring subsequent macOS system updates and will continue to optimize compatibility for related functions.

Important Notes:

This macOS Sequoia update has a wide-ranging impact, not limited to specific software. Many users may encounter similar problems when using network storage devices.
We need to wait for Apple to resolve these SMB protocol-related issues in subsequent updates.

2. PSD and Other File Type Thumbnail Display Issues

After the macOS Sequoia (15.0) system update, some users have reported that PSD files and other file types' thumbnails cannot display normally or appear abnormal.

Root Cause:

Through our engineering team's in-depth investigation, the problem stems from macOS 15 system's major changes to file thumbnail-related APIs. Specifically:

Apple discontinued support for legacy Quick Look Generator plugins.
Introduced new APIs and extension mechanisms to replace the original functionality.

These changes directly affected Eagle and many other software's file preview functions.

Solutions:

We have fixed the main compatibility issues related to macOS Sequoia in Eagle 4.0 build4 version. We strongly recommend you obtain and install the latest version from the official download page.
Please note that due to system limitations, the current version's file preview functionality may differ from previous versions: double-click preview image clarity may be temporarily reduced, and preview functionality for certain file formats may be temporarily limited. We are closely monitoring subsequent macOS system updates and will continue to optimize Eagle's performance and compatibility.

Important Notes:

This macOS Sequoia update has a wide-ranging impact, not limited to Eagle. Many well-known software applications (such as Affinity Photo, Designer, etc.) have their preview functions similarly affected.
If you find that certain file formats cannot be previewed with the spacebar in Finder, the corresponding preview function in Eagle may also be temporarily limited.
We need to wait for related software vendors to fix their respective preview issues before Eagle's complete preview functionality can be fully restored.

Reference Materials:

We sincerely apologize for any inconvenience this may cause and thank you for your understanding and support. The Eagle team will continue to work hard to provide you with higher quality products and services. If you encounter any issues, please feel free to contact our customer support team at any time.

Your feedback is the driving force for our continuous improvement, and we will do our utmost to ensure your user experience.

Not recommended for Eagle users to update to macOS Sequoia (15.x) version
