Hello! I moved your message to the Illustrator forum

When is AI slow? at boot during use? certain tools more than others?

Which exact version (check in "about Illustrator"?

Hi Abbas,

So sorry to hear about this issue. I would request if you can share a few more details like:

• Exact version of Illustrator.
• Is it slow on a particuler action or while using some particular feature/ tool?
• 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 and share the download link. 
• Where the files are saved (Network Drive/ System HDD/ Shared Folder on System /External HDD)? 
• Does resetting Illustrator Preferences (https://helpx.adobe.com/in/illustrator/using/setting-preferences.html) help resolve 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.

Regards,

Srishti

Hi!

I have the same problem, I have Illustrator 2019 CC and since I updated to Catalina, it's very slowly responding. 
For example when I'd like to modify an ancher point, it's simply doesn't follow my lead and at anchors in a different point than I'd like it to. This makes illustration very hard and annoying, thinking about downgrading back to Mojave, because I'm having the same difficulties in Photoshop (there is an extreme brush lag). 
Please advise if I can do something. Thank you!

Hi Eszter,

Thanks for sharing the details. Please try following these steps and share your observations:

1. Reset Preferences: - 

• Close all Adobe applications. 
• Go to locations 
• ~/Library/Caches 
• ~/Library/Application Support/Adobe 
• ~/Library/Preferences 
• Rename  Adobe Illustrator, com.adobe.illustrator and Adobe Illustrator 23 Settings folders to   Adobe Illustrator.old, com.adobe.illustrator.old and Adobe Illustrator 23 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.  

2. 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. 

3. 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

Hi. I've recently discovered and posted on the Adobe Indesign comminuty board that if you change the colour PREFS from LG UltraFine to Apple RGB in the display settings, all works brilliant. Seems that there is an issue with Adobe's code with LG UltraFine monitors. Pass this on please.

Thanks for reaching out, Nicholas. Does it fix performance issues for Illustrator and other Adobe applications as well?

Regards!

I, too, have been plagued with performance issues from Adobe since upgrading to Mojave. I've searched extensively, employeed copious "fixes" from both Adobe AND Apple to no avail. The only thing I knew that actually worked was to diconnect my iMacPro from the network before launching any Adobe software. So it's something that the apps are calling out home for.... well, I found this extensive list of Adobe servers that bootleggers use to block activation, amongst other things, via the hosts file. I employed it myself even with my account still active and legit. Everything is running like a champ now! Back to High Sierra responsiveness! Creative Cloud wanted to fix two entries with their Limited Access Error Tool, I allowed it, and it has not impacted performance at all. I highly suggest giving it a try. PM me for the list.

Hi Chris,

Thanks for reaching out. I have sent you a DM for more details.

Regards,

Srishti

[Nicholas Petropoulos]

Yes. All Adobe CC programs, including Bridge. That's my experience. Was surprised as to how much.

[Srishti Bali]

Thanks for sharing this. I will definitely pass it on to our Product team. 

Regards!

How is a DM useful to anyone in the community. Put the knowledge in public space. How can Adobe put out software which is incompatible or next to useless with industry standard hardware (2020 iMac) what is going on????

Because said info could, or lead to information that could, potentially violate forum guidelines or conver sensitive information, despite its usefulness. That said, use your search engine of choice to look up hosts port blocking for this software.

I think this is a general problem with individual color profiles.

I work on an Eizo CG248-4K and switching to Apple RGB was the only temporary solution beside a few not-so nice workarounds.

You just saved my night. Thank you!!!

Adobe RGB, Apple RGB ou Diplay, anything but LG Ultrafine works fine on my MacBookPro

[M.Osman]

I had the same issue, I enabled GPU Performance in Illustrator Perferences and it started to work smoothly.

This solution totally solved this for me. Thank you so much.
