Adobe Illustrator 2020 quits unexpectedly on macOS 10.15.1

Hello! Just in case you haven't resolved your issue yet... I too am running the same specs/mac and my InDesign, Photoshop, and Illustrator all were quitting unexpectedly.  I don't have time to screw around with fixes _ I had an online chat with Adobe support team and these are the steps with links I was told to follow - so far, so good. All is fixed. I don't know if it matters or not but I work remote and on a home network.  Anyhow, good luck!!

Step #1:  Please run the cc cleaner tool from the link given below and clean all.

Step #2: Once you are done with the above step, please install the creative cloud from the link given below and login with the adobe ID, after that let the creative cloud update. Once the creative cloud is updated you will be able to install the application.

Hi all,

Thanks for reaching out. I would request if you can try following these steps and share your observations:

• Please try resetting the preferences once. Follow instructions on
  https://helpx.adobe.com/illustrator/using/setting-preferences.html#setting_illustrator_preferences
   
  **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.

• Try turning off  GPU Performance under Preferences > Performance. Also, try disabling "Automatic graphics switching" from System Preferences (Click Apple menu > System Preferences and click Energy Saver).

• If that doesn't help, try booting the system into Safe Mode (https://helpx.adobe.com/in/x-productkb/global/start-safe-boot-mode-mac.html) and check how it works there. It starts your system so that it performs certain checks and prevents third party software/ services from automatically loading or opening. If it works fine in Safe mode, then there is some third party service or application like antivirus, plugins or web extensions which are conflicting with the Illustrator.

• If that doesn't help either, login to root account (https://support.apple.com/en-in/HT204012). Check how application works there. If it works fine there, then it could be related to permission errors. Follow these steps to repair permission errors: https://helpx.adobe.com/in/illustrator/kb/preferences-folder-read-only-error.html

• If nothing helps, then we need to troubleshoot this on a live session. Please head here (https://helpx.adobe.com/support.html) and select the chat button in the lower-right corner of the page. We can help on a live session that way.

I am having the same issue with OS 10.15.1 and Illustrator 2020 and I have now wasted more than 10 hours trying to fix this and work around the crashes.  I have cleared my caches, I have restarted my machine probably 100 times, I have unistalled and reinstalled Illustrator multiple times, I have unchecked GPU Performance, and I have tried only starting Illustrator with my WiFi disabled (all things suggested on other forums).  I do actually need Illustrator to work to do my job, so I hope there is a an actual solution to this!

Hi there,

Thanks for reaching out. I'd recommend you to reset the preferences. You may follow the steps below:

• Close all Adobe applications. 
• Go to locations 
• ~/Library/Caches 
• ~/Library/Application Support/Adobe 
• ~/Library/Preferences 
• Rename  Adobe Illustrator, com.adobe.illustrator and Adobe Illustrator 24 Settings folders to   Adobe Illustrator.old, com.adobe.illustrator.old and Adobe Illustrator 24 Settings.old 
• Launch Illustrator from the Creative Cloud.

**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. This way all your old settings will be saved in .old folders and Illustrator will recreate new folders with default settings.

You may also try to reboot your machine in safe mode and see how the app is responding there. You may follow the steps given on https://helpx.adobe.com/x-productkb/global/start-safe-boot-mode-mac.html

Let us know how it goes. Looking forward to your response.

Regards,

Ashutosh
