Altair EmployeeHi Naveen,
It will be a day or so before I can get to a Mac on which to try this, although it does not seem to be a new issue since I found the following post, where the same error occurred in 2023:
Out of curiosity, can you tell me if the following directory exists on your system, and if it does, can you test to see if you can create a file there? /Users/<username>/.AltairRapidMiner/AI Studio/2025.1.0/internal cache/browser8.3.0-OSX
Hi Nicholas,
Thank you for reaching out. I don't see that folder.
Altair EmployeeI see - is there any folder directly under the
/Users/<username>/.AltairRapidMiner/AI Studio/2025.1.0/internal cache/
folder which begins with the string "browser"?
Altair EmployeeOh, could you also tell me when the error is occurring? Is it always on startup, or do you take some steps which lead to this issue?
Hi. I don't have the AltairRapidMiner folder under the user directory. Also, the issue appears when I click on visualizations. Thank you again
Altair EmployeeYou're quite welcome.
At this point I would need to take a look at your system and to do that, you will need to open a Support ticket.
Could you please visit , create a Support ticket and please mention that you'd like Nicholas Linsky to work on it.
I have the same concern, @Nicholas_21406 could you also lend me a hand on how to address this concern. thanks
Altair EmployeeI would also ask you to open a support ticket at so that we can take a look at your system on a screenshare.
Thanks!

Altair EmployeeHi @Makssssssssssss ,
Sorry to hear you do not have access to open a Support ticket.
If https://community.altair.com/profile/481003/NaveenA opens a Support case, then I will meet with them to try to diagnose what is the issue there, which might give me more ideas I can post here.

Hi Nicholas, I am also facing the same issue. However, I could see the folder /Users/<username>/.AltairRapidMiner/AI Studio/2025.1.0/internal cache/browser8.3.0-OSX, as well as could move a document created there. What next? How to fix the browser issue to open the visualisation on my MacBook with macOS Sequoia 15.5.
Altair EmployeeHi @Vani_Vasudevan ,
I will be meeting with @NaveenA on Friday and hope to have more information at that point, which I will post back to here.
I would also be happy to look at your system, which would require you to open a Support ticket at https://support.altair.com/

Altair Employee@NaveenA, @Makssssssssssss , I have met with @Vani_Vasudevan and collected the information I needed about this issue.
It appears there is indeed a defect in the 2025.1.0 AI Studio Macintosh edition.
I am going to be filing the defect shortly and will let you know what the developers say, but as an interim test and workaround, could you please download the 2025.0.1 version of AI Studio and install it - you do not need to uninstall 2025.1.0.
To find this previous version on the Marketplace, just select the dropdown for the AI Studio version number, also select the "Show previous versions" checkbox, and then download the older installer.
Please let me know the results of your test.
Yes. Visualization works with 2025.0 version. But, I had to use 2025.1.0 . Kindly help to resolve the issue.
Attached are log files. Thank you for assisting.
