I'm having the same problem. It is so frustrating, I can't work this way!
Having a similar issue..
I share out a Mac OS Extended (Journaled) drive to multiple Windows 7 Pro.
Everything seemed to be working fine until the read-only error showed up.
All this takes is for a user on Windows to open (parse) a file and close without saving. When the file is opened on the Mac, it becomes “read-only”.
It doesn’t seem to be a permissions issue since I can delete the file from the desktop and no issues with file info or properties.
Cmon Adobe, getting annoyed by your support letting these issues languish.
I'd guess that it's a permissions issue on the files you're seeing that message on.
For the Macs, I'd suggest using the Disk Utility in Utilities to repair permissions on your computer.
Thanks for the input..
I did check the permissions, and found no issue running the disk utility. Granted, this is a non-booting data drive, but will check boot disk as well.
I opened the drive permissions for "everyone" to no-access. Also for simplicity, I am using my login credentials for the connected machines.
Anyway, I did a process of elimination, (other files including AI, PS as well as Office 2010 junk) and did not run into the read-only issues. Was able to save over the top of all except for ID files. Seems pretty specific to the ID file type.
Just a note, this drive has been shared right under 2 years without this issue.
OS X 10.9.5
Problem finally resolved by upgrading my Mac to El Capitan. Now I can save InDesign files on the NAS server, no problem. However, after the upgrade I noticed some of my folder names had changed to gibberish!! I found out it's a problem with El Capitan's file sharing protocol, not recognizing SMB. Instead you have to use AFP…OS X El Capitan: Set the protocol for file sharing
I set my sharing option to SMB for the windows share. I'm making an assumption that this is correct sharing method with Windows and AFP is is Mac to Mac.
Yes Mac to Mac
Seems to be fixed.. for now
Although I did run a disk verification on the shared drive (data drive), I also ran a disk verification and permissions repair on the boot drive.
I went back to may Share settings and set my options to SMB specifically by deselecting AFP.
Removed the credentials and re-mapped my shared drive on each windows machine.
Just seems very weird that it only affected one file type.
Now off the the next mystery
Does Bridge display Office 2010 Documents (Word Excel and Powerpoint) thumbnails in windows?
After a bit more observation on this Mac, I've found that when it happens, the .idlk file isn't created at all when the document in question is opened.
Closing the document and re-opening it, the .idlk file is created by InDesign and the file opens fine, so it must be an issue with that copy of InDesign on that particular Mac, it's not a permissions issue on the server.
Also when another Mac tries to open the same file that's open on the Mac in question, and the .idlk file isn't created, that document is opened as ready only on the other Mac as well.
I don't know whether that narrows down the issue or not - any help greatly appreciated.
I know this issue is back in 2015, but have you found a solutions to it?
We are also experiencing inDesign files opened as read-only from SMB shares, and in all instances when this problem happens the .idlk file is not created
What could be causing this? We are using Adobe CS6 with inDesign 8.0
Thank you so much for any help you guys can give us!
I know in the past, files opened on windows servers had issues because the temp .idk file's name was too long for the server and that generated all sorts of problems.
Thanks so much Dave!
One of the root folder was name with a dot, I've replaced the character with an _ and it seems to have solved the issue. Your comment lead me to this article: OS X: Cross-platform filename best practices and conventions - Apple Support so thanks again for your help!
