Trim view not working

I`m having the same issue here.

Trim view worked just fine a few month back, but now it`s greyed out. I`m on Mac latest OS and the latest update of Adobe Illustrator. On Adobe Illustrator 2020 it`s not working either. I`m coming to believe this is related to storage and memory issues. 

Hi there,

Sorry to hear about this trouble. I tried but couldn't replicate this behavior at my end. I would request if you could share a few more details like:

• OS and version of Illustrator
• Screenshot of layers panel (Showing all layers and sub layers)
• Is the issue related to a specific document? If yes, could you please share the 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. 

You may also try resetting Illustrator Preferences ( https://helpx.adobe.com/in/illustrator/using/setting-preferences.html ) and let us know if that resolves the issue.

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.

We're here to help, just need more info.

Regards,

Srishti
