On a Mac. operating system is Golden Gate 27.0. I ran an update to InDesign 21.6, and now when I open files, make changes, and try to save them, InDesign tells me that my files are damaged

When does Adobe plan to fix the compatibility issue with Golden Gate? Albeit, premature to have upgraded, I have never had such incompatibility issues ever. And the fix to down grade to a lower OS seems extremely cumbersome. Is there an ETA?

Alright, so here's the deal. This looks less like your files are actually damaged and more like 21.6 not playing nice with how Golden Gate 27.0 handles file access. A few things worth trying, in order:

    1.    Save to a local folder. If the file lives on iCloud Drive, Dropbox or a network drive, move it to your desktop (with iCloud Desktop & Documents sync off) and try again. This fixes it more often than you'd think.

    2.    Save As a new filename, not Save. Quick way to tell whether it's the file or the save path.

    3.    Export to IDML (File > Export > InDesign Markup), reopen that, then save. It rebuilds the document cleanly.

    4.    Check permissions. System Settings > Privacy & Security > Full Disk Access, make sure InDesign is on.

    5.    Reset preferences. Hold Cmd + Opt + Ctrl + Shift while launching InDesign and confirm the reset.

    6.    Still broken? Roll back. Creative Cloud app > InDesign > ⋯ > Other versions, grab 21.5 until Adobe pushes a patch.

My money's on #1 or #6.

Quick question for the Premiere Pro folks while we're here: has anyone on Golden Gate 27.0 seen similar save or "damaged project" errors after the latest Premiere update? Trying to figure out if this is an InDesign bug or a wider Creative Cloud + macOS thing before I update my editing machine.

Hi, thanks for reaching out. We're sorry about the trouble.

I've updated to macOS 27.0, but I'm not seeing the same behavior while trying to save from InDesign 21.6.

Could you let us know where the original files are located and where you are trying to save them to?

Meanwhile, please go to the System Settings on your Mac, then Privacy and Security, and check whether InDesign is enabled for Files and Folders and Full Disk Access.

Thanks,

“Dot-oh” versions are alway risky, whether it’s an OS or Adobe software. On a production machine, you should wait about 6-9 months before updating unless there is a feature you absolutely need. 

InDesign (as well as other Adobe products) is not supported on macOS 27 yet. In addition to this, I think I just saw reports that updating to InDesign 21.6 causes the problem you describe when saving files on a network.

So first, try to roll back to InDesign 21.5.x: Creative Cloud app > InDesign > 3-dot menu > Other Versions

If it doesn’t solve the issue, you’ll need to go back to a stable macOS version such as Tahoe. I don’t know if you updated your existing system to Golden Gate (in which case it was a premature step) or if this is a new machine with Golden Gate pre-installed. In any case, create a separate volume on your hard drive using Disk Utility, install Tahoe there, and work from there until macOS 27 is supported.
