Toolbox App 3.7: JVM Memory Optimizations and Update Improvements

Toolbox App 3.7 enables JVM memory optimization by default, improves the reliability of updates and session expiration recovery, and ensures compatibility with Windows Smart App Control.

Action required: Update Toolbox App on Windows

If you’re using an older version of the Toolbox App (3.4 or earlier) for Windows, update to v3.7 or later to keep signing in to your JetBrains Account. Earlier versions may be unable to store or refresh the credentials currently used by some JetBrains services.

Reliable IDE installation and updates on macOS 27

The Toolbox App now installs and updates IDEs reliably on macOS 27. 

JVM memory optimizations by default

With JVM memory optimizations now enabled by default, the Toolbox App helps the JVM use memory more efficiently in all operating systems. The new configuration tunes memory management, code-cache behavior, and garbage collection without requiring setup. See TBX-18852 for more details.

Fixed compatibility with Windows Smart App Control

The Toolbox App now launches correctly when Windows Smart App Control is enabled. See TBX-18777 for more details.

Patch update improvements on macOS 

Some JetBrains IDEs write runtime files inside their macOS app bundle. When you install a patch update, the Toolbox App now verifies the updated bundle’s code signature and removes files that are not sealed by the new build. If the bundle still fails verification, the Toolbox App downloads a clean copy. See TBX-18856 for more details.

Session expiration improvement

If you’ve experienced “session has expired” notifications, please try the Toolbox App 3.7 update. We’ve addressed one possible cause (temporary network interruption), and we’d appreciate a report if the problem persists for you.
