Getting "An unknown error has occurred" when trying to save a file in Illustrator on macOS 10.15.7

Hi there,

Sorry about the trouble. Could you please share a few more details like:

• The exact version of Illustrator
• Does this error occur while saving a specific document or all?
• Is this a new or old document?
• Where are you trying to save this document (Network Drive/ System HDD/ Shared Folder on System/ External HDD)?
• 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.
• 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.
• Does updating macOS help resolve the issue?

Also, you may try running the app in Root Account and see if you are able to save this document there.

We are here to help. We just need more info.

Thanks & Regards,

Anshul Saini
