I have received an update for my Mac-Apple M3. Katalon Studio Arm 64, 9.7.5. My current version is macOS Sequoia version 15.4.1 (24E263). Since then I suddenly get Katalon Studio crashes during normal scripting. It really annoys me because I always get the crash every 10-15 minutes. I have tried Katalon 10.1.1 as well, same issue. ---

To resolve the Katalon Studio crashes on macOS Sequoia (15.4.1) for Apple Silicon (M3) devices: ## **1. Verify JDK Compatibility** Katalon Studio 9.7.5/10.x requires **JDK 8/11/17** for ARM64. **Steps:** 1. Uninstall existing JDK: ```auto /usr/libexec/java_home -V # List installed JDKs sudo rm -rf /Library/Java/JavaVirtualMachines/ ``` 1. Install **Azul Zulu JDK 17 for ARM** : Download [here](https://www.azul.com/downloads/?package=jdk) (macOS ARM64 .dmg). 2. Configure Katalon to use Zulu JDK: - Go to **Katalon Studio \> Preferences \> Java \> Installed JREs**. - Add the Zulu JDK path (e.g., `/Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home`). ## **2. Disable Hardware Acceleration** GPU rendering issues often cause crashes on Apple Silicon after macOS updates. **Fix:** - Open `katalon.ini` in `/Applications/Katalon Studio [version].app/Contents/Eclipse/`: ```auto -vmargs ... -Dorg.eclipse.swt.internal.carbon.smallFonts -Dorg.eclipse.swt.internal.carbon.noAutoScale=true -Dsun.java2d.metal=false # Disable Metal API -Dsun.awt.disablegrab=true ``` - Add these lines to disable GPU rendering: ```auto -Dsun.java2d.opengl=false -Dsun.java2d.d3d=false ``` ## **3. Run Katalon in Rosetta 2 Compatibility Mode** (For Intel-based Katalon versions only) 1. Right-click Katalon Studio.app → **Get Info**. 2. Check **Open using Rosetta**. ## **4. Update macOS Environment Libraries** Apple Silicon (M1/M3) often requires manual linking for legacy libraries: ```auto # Fix libjvm.dylib issues sudo ln -sf /Library/Java/JavaVirtualMachines/zulu-17.jdk/Contents/Home/lib/server/libjvm.dylib /usr/local/lib ``` ## **5. Clear Katalon Caches** Corrupted caches post-update can cause instability: 1. Close Katalon. 2. Delete these folders: ```auto rm -rf ~/Library/Application\ Support/KatalonStudio rm -rf ~/Library/Caches/KatalonStudio ``` 1. Restart Katalon. ## **6. Run from Terminal with Debug Logs** Identify crash triggers using verbose mode: ```auto cd /Applications/Katalon\ Studio\ [version].app/Contents/MacOS/ ./katalon --consoleLog --debug ``` ## **7. Temporary Workaround for Scripting** Use **VS Code + Katalon Plugin** for script editing to reduce Katalon’s UI load: 1. Install [Katalon TestOps Plugin for VS Code](https://marketplace.visualstudio.com/items?itemName=Katalon-LLC.katalon-testops). 2. Export tests from Katalon Studio and edit in VS Code. 3. Run tests via CLI: ```auto ./katalon --args -noSplash -runMode=console -projectPath="$(pwd)/your.prj" -retry=0 -testSuitePath="Test Suites/your_testsuite" ``` ## **8. Known Issues & Patches** - **macOS Sequoia 15.4.1** has a bug with JNI libraries in ARM64. **Workaround** : ```auto export JAVA_OPTS="-Xdock:name=KatalonStudio -XstartOnFirstThread" ``` - Update to **Katalon 10.1.1+** and apply [Patch 10.1.1.221](https://github.com/katalon-studio/katalon-studio/releases) for Apple Silicon fixes. ## **9. Full Clean Reinstall** 1. Use [AppCleaner](https://freemacsoft.net/appcleaner/) to remove all Katalon traces. 2. Download the latest **ARM64 build** from [Katalon’s site](https://katalon.com/download). 3. Install with: ```auto hdiutil attach Katalon-Studio.dmg cp -R /Volumes/Katalon\ Studio/Katalon\ Studio.app /Applications ``` ---

I got an update from Katalon support side. I hope it will help me: ```auto Please be informed that, after investigating, we found out that there is an incident from macOS with the Eclipse application, which is reported in SWT: [https://github.com/eclipse-platform/eclipse.platform.swt/issues/1978](https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_eclipse-2Dplatform_eclipse.platform.swt_issues_1978&d=DwMCAw&c=BSDicqBQBDjDI9RkVyTcHQ&r=QTNAPbwpIA6OI4GnYI05KZbPXM4JAw5XyYPnJT3tSnc&m=RyN_2JHXGuspgQgNnDSsf4rKl5Ol0Dkr9ScKfgn_kxp1fo-SzckyFmXdGR482OAg&s=5gLOpXA0G_2593juBcFZ262XNuhkyhHu9wlVjFAWk4w&e=) While waiting for the fix from the macOS side, there is a workaround so it should no longer crash from the JavaDoc: disable the hover tooltips. Please help go to Preferences -> Java -> Editor -> Hovers -> and uncheck the Combined Hover: ```
