Running Instruments from the command line I started getting this:
instruments[2387:30342] Connection peer refused channel request for "com.apple.instruments.server.services.wireless"; channel canceled <DTXChannel: 0x7fa7116b7a10>
Any idea what the problem is and how to fix?
I'm also doing some research to find out the root cause of the problem. However, making sure Instruments is not running and/or restarting the device solved the issue.
