indesign could not package the document cannot copy necessary linked files

Question

After updating to both Tahoe 26.1 and ID 2026, I can no longer package files located on my Synology NAS. I'm getting the "indesign could not package the document cannot copy necessary linked files" error. I can package if all of the files are on my local drive. This is fine, except I have thousands of files on the NAS that my studio works from.

Anyone have a solution for this? I'm going nuts.

My phone call with Adobe support was "if you resaave all of the linked files with new names in new locations, they will re-link up" This is a nightmare for a studio, so its a non-starter.

Affinity works fine, and would be a PITA to move to, but I'd prefer for now to stick with ID.

Hi @atracksler,

Adding to what expert suggested, please try testing the behavior in Safe Mode to rule out any third-party interference during the packaging process (Ref: https://adobe.ly/4r1ueU4). You can also check this similar community thread where other users encountered the same issue: https://adobe.ly/4p9Xp5s.

As noted there, the problem seems tied to how InDesign interacts with NAS volumes connected over SMB on macOS 26 (Tahoe). The team suggested trying an AFP connection instead of SMB, as this often resolves the issue. Please give this a shot and let me know if it helps.

Looking forward to your update.

Abhishek
