When you encounter the Error: EACCES: permission denied, mkdir error, it typically indicates that Eagle cannot create folders or write files at the specified location, which is usually related to disk permissions or format. Here are several solutions:

Check Disk Read/Write Permissions

When software has insufficient permissions on the disk, several important issues can occur. For example, the software may not be able to smoothly import, download, and save data. Additionally, being unable to read or write executable files on the disk may also cause the software to fail to run properly.

Confirm the Disk Format is Natively Supported by the System

Native format refers to the disk format adopted by default by the operating system, such as NTFS for Windows and APFS and HFS+ for macOS. When the disk's file system is inconsistent with the operating system's native format, it may cause files to be unreadable or unwritable, or file read/write speeds to slow down.

NTFS Format Not Recommended on macOS (macOS Only)

The Eagle team has conducted extensive testing on plugins like Tuxera NTFS / Paragon NTFS, and regardless of which NTFS plugin is used, none can achieve even half of the disk's original performance, resulting in severe slowdowns.

Use System File Manager to Check Access to Library Storage Location

By directly accessing the library storage location through the system file manager, you can check file access capabilities and permission issues.
