Hi Katalon, In this doc [https://docs.katalon.com/docs/release-notes/katalon-studio/katalon-studio-release-notes-version-9.x](https://docs.katalon.com/docs/release-notes/katalon-studio/katalon-studio-release-notes-version-9.x) ![Untitled](https://europe1.discourse-cdn.com/katalon/original/3X/4/d/4dd07fecf62d82ccaf2fced6841404dc62d4fca8.png) I see that KRE does not support for apple Silicon Chip. In my case: I want to use KRE in my M1 mac. Is there any way to do that? When will KRE have a version for Apple Silicon Chip? ![Untitled](https://europe1.discourse-cdn.com/katalon/original/3X/0/f/0fc9a92354d69e9fadefdd24f117875712e94f7a.png) ---

> [@trungnghia.ctn94](#): > > In my case: I want to use KRE in my M1 mac. I guess, you should just try running KRE on your M1 mac. It should run. Why I guess so? See the following post by @duyluong of Katalon > [@Katalon is slow to execute tests cases on MAC](http://forum.katalon.com/t/katalon-is-slow-to-execute-tests-cases-on-mac/99924/30): > > Katalon Studio v9 introduce mac ARM support so you can try that version. If your computer is slow, please observe Task Monitor to see any process that affects Katalon Studio. But again, Macbook Air (or even Macbook Pro) with 8gb of RAM only allow you to do basic stuffs I guess that Katalon Runtime Engine is built as a x86-64-based application software. On mac with Apple silicon chip, KRE run on top of a emulation layer named [Rosseta 2](https://en.wikipedia.org/wiki/Rosetta_(software)). The Rosseta 2 provides an X86-inteface to the application. The x86-64 to Arm64 instruction translation makes the application run slow. So KRE should run on Apple M1. However you should note that it could be **slower** than Katalon Studio for Arm64. Here is a performance comparison report: [Katalon is slow to execute tests cases on MAC - #31 by kazurayam](http://forum.katalon.com/t/katalon-is-slow-to-execute-tests-cases-on-mac/99924/31) ---

hi @kazurayam , tks for your response, but I can not start KRE 9.3.0 on my M1 Mac, …Are you running it on M1 chip? You can refer to the link in my post. Tks! ---

> [@trungnghia.ctn94](#): > > I can not start KRE 9.3.0 on my M1 Mac, Show the error log, please. I guess, type of the chip (Intel or M1) is not the reason of the fault you have now. ---

Hi @kazurayam , I can execute tests with KRE based on your answer on my m1, but I need to relate them to AWS Device Farm, because for iOS 17+ AWS will use Base Host on Apple Silicon. → So maybe KRE will not be able to execute in the above case. **Error Log:** ```auto Feb 20, 2024 10:27:20 PM com.kms.example.aw_ios.utils.ConsoleLogger info INFO: Execute [sh, -c, "/private/tmp/devicefarm-workspace/execution-pza6vzf0/test-package-in050786/tmp/.katalon/9.3.0/Katalon_Studio_Engine_MacOS-9.3.0/Katalon Studio Engine.app/Contents/MacOS/katalonc" -noSplash -runMode=console -projectPath="/private/tmp/devicefarm-workspace/execution-pza6vzf0/test-package-in050786/tmp/My_Project" -retry=0 -testSuitePath="Test Suites/AWS_TestSuite" -executionProfile=default -browserType=Remote -reportFolder=/tmp/devicefarm-workspace/execution-pza6vzf0/logs-a1hnhk95 -apiKey=b29e1a55-d0b9-4159-85c0-41740938b172] in /var/folders/wr/q71xs5157vj8twl0x6t0j3l00000gr/T/katalon-12014993042029103128 Feb 20, 2024 10:27:20 PM com.kms.example.aw_ios.utils.ConsoleLogger info INFO: sh: /private/tmp/devicefarm-workspace/execution-pza6vzf0/test-package-in050786/tmp/.katalon/9.3.0/Katalon_Studio_Engine_MacOS-9.3.0/Katalon Studio Engine.app/Contents/MacOS/katalonc: Bad CPU type in executable Feb 20, 2024 10:27:20 PM com.kms.example.aw_ios.utils.ConsoleLogger info INFO: Finished executing sh -c "/private/tmp/devicefarm-workspace/execution-pza6vzf0/test-package-in050786/tmp/.katalon/9.3.0/Katalon_Studio_Engine_MacOS-9.3.0/Katalon Studio Engine.app/Contents/MacOS/katalonc" -noSplash -runMode=console -projectPath="/private/tmp/devicefarm-workspace/execution-pza6vzf0/test-package-in050786/tmp/My_Project" -retry=0 -testSuitePath="Test Suites/AWS_TestSuite" -executionProfile=default -browserType=Remote -reportFolder=/tmp/devicefarm-workspace/execution-pza6vzf0/logs-a1hnhk95 -apiKey=b29e1a55-d0b9-4159-85c0-3213213213 .

> [@trungnghia.ctn94](#): > > `MacOS/katalonc: Bad CPU type in executable` Quite likely, this is a bug. KRE seems to be no longer runnable on Apple Silicon. =\> @Elly_Tran @trungnghia.ctn94 This user forum is not an appropriate place to discuss about the Katalon products’ bugs. The developers are not watching the threads here. You are possibly an Enterprise licensee. So you should raise a ticket to Katalon through the official path: [Support Portal](https://katalon-inc.my.site.com/katalonhelpcenter/s/article/How-to-submit-a-Support-Case). ---
