Latest IntelliJ not compatible with macOS 26 / Tahoe?

Hello Gunter,

Please clarify if this issue occurs when you're using IntelliJ IDEA or another IDE.

For further investigation, please collect your IDE logs via Help | Collect Logs and Diagnostic Data, upload them to our server, and provide us with the Upload ID.
If you are unable to collect logs via IDE, you can open the log folder manually (they are stored in the ~/Library/Logs/JetBrains/<product><version> directory), add it to the archive and send it to us.

The uploaded data will be accessible only to our team and will be used solely for investigating this issue. Thank you!

Apologies, this is for IntelliJ idea. Just realizing now I am in the wrong support forum.

Thank you for your answer!
Could you please create a new ticket and attach logs to it using the steps above. 
We will consider your problem individually.

Hi @Aleksandr Nagovitsyn
 

This happen to all IDEs Webstorm,  Idea, etc

This problem may be caused by the metal render. Please try to disable the Metal rendering framework for the IDE:

1. Open the VMoption file in the IDE: Help | Edit Custom VM Options…
2. Add the following string: -Dsun.java2d.metal=false
3. Restart the IDE

Does it help?
If not, need more details to further investigation (at least IDE logs).

Thanks Aleksandr Nagovitsyn - that solved the issue with me.

Thank you for your feedback!
We are working on this problem related to Metal rendering. You can find popular issues in our YouTrack tracker and subscribe to them. Issues JBR-9171 and JBR-8637 are likely related to your problem.

If the problem persists after disabling metal rendering, please create a new support ticket and we will review your issue.

Hi Aleksandr Nagovitsyn ,

I've tried to install latest Intellij version on my macos 26 tahoe and now Idea is not even opening, any idea how to fix that?

I tried already to uninstall but no luck.

Hi Rodrigo, 

If the problem with starting IDE persists, please create a new ticket using this link and attach the log received after running the command to the ticket: 
~/Applications/IntelliJ\ IDEA\ Ultimate.app/Contents/MacOS/idea 2>&1 | tee ~/idea-launch.log

We will be happy to consider your problem individually!

This is also happening to me across multiple JetBrains IDEs - GoLand, WebStorm, and Android Studio all freeze when I use the terminal. Once it happens, I can't interact with the IDE at all and have to force quit. This occurs on macOS 26 / Tahoe as well.

I'll try the Metal rendering workaround mentioned by @Aleksandr Nagovitsyn (-Dsun.java2d.metal=false in VM Options) and report back if it helps.

Update: I tried the Metal rendering workaround (-Dsun.java2d.metal=false in VM Options) and it's working for Android Studio. Still testing GoLand, WebStorm, and PyCharm.

However, this is a critical issue that needs to be addressed and fixed immediately. macOS 26 / Tahoe is a public release, and having all JetBrains IDEs completely freeze and become unusable is a major problem for developers. While the workaround helps, a proper fix should be prioritized given how widespread this issue is.

Hi Aleksandr Nagovitsyn ,

After reinstalling Intellij IDEA to latest version luckily back to work for me.

Hi all,

Rodrigo, I'm glad to hear that this helped solve the problem.

Dear Rasmus Jensing, I'm sorry to hear that you've encountered these difficulties. We take these issues seriously and do not ignore them. Please ensure that you are using the latest version of the IDE. Problems related to IDE freezes on macOS 26 should have been resolved within ticket JBR-9171.

If, after updating to the latest version, you encounter this issue again (with the Metal renderer enabled), I kindly ask you to create a new ticket and attach your IDE logs via Help | Collect Logs and Diagnostic Data. This will help us investigate the specific problem you are facing in detail. Since investigating a problem like this requires time and additional data, it would be inefficient and take too long to handle it on the forum. Thank you for your understanding.
