Unable to copy from Illustrator v25.4.1 and paste into Photoshop v25.5.0 & InDesign v16.4 on macOS

Hi there,

Sorry to hear about the trouble you are facing. Could you please share a few more details like:

• What are you trying to copy from Illustrator and paste into Photoshop and InDesign (Text, object, vector, etc.)
• Does this issue occur while copying from a specific document? Could you please share a sample .Ai document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link.
• When did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates, or web extensions installed recently.
• Are you using any clipboard app or extension?
• A small video demonstrating the issue could be really helpful.
• Screenshot of File Handling/ Clipboard Handling settings from the preferences of Illustrator, InDesign, and Photoshop (cmd + k > File/ Clipboard Handling)
• Does resetting Illustrator Preferences ( https://helpx.adobe.com/illustrator/using/setting-preferences.html) help to resolve the issue?
  Disclaimer: Please note that resetting preferences will remove all the custom settings, and Illustrator will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article.

Also, you may try running the apps in Safe Mode and let us know how it goes.

Thanks & regards,

Anshul Saini
