Hey everyone!
I know this is old but if someone stubles across this like I did here's the fix...
I'm running MacOS Sequoia 15.2. To get rid of this error you have to do a couple of things:
- Install xcode from the app store.
- VERY IMPORTANT Open xcode from your Applications menu and answer all of the questions (install the version for MacOS). If you don't do this xcode isn't installed even though you installed it from the app store.
- Download and install the appropriate driver. For most it's CP210x. I did a reboot after installation
- Download m5burner and install it.
This worked for me. I noticed the first time I did a burn it took a long time, but part of that is I was using UIFlow2.0 with all of the account binding stuff.
Hope this helps!
