Unable to Debug in VSCode - MacOS - spawn Unknown system error -86

[zoob]

Hi folks,

Recently picked up a new MacBook (M series) and was excited to try some sample projects on my nrf52840dk.

Unfortunately upon trying to Debug, I get the following error: spawn Unknown system error -86

I took a quick look at the forums and found the following thread but unfortunately this did not lead me anywhere

 Cannot debug project in VS code [spawn Unknown system error -86] 

I have included my "support info" here

  }
}

I do realize that I am using Segger J-link v8.10i. Downgrading to v7.94i did not fix my problem so I updated it back to v8.10

A couple of additional notes:

• I am using a basic blinky project from the sample for the testing
• Flashing works just fine
• I am able to use the command line version of gdb to set breakpoints and step through the code without issue
• This board and sample projects work my other PCs (Linux and Windows)

Your assistance is greatly appreciated
