Compile Error: dyld: Symbol not found: _unlinkat

I am getting the subject compile error. It even happens with the sample Arduino codes built into the IDE (below is the error for the basic Blink example).

I have the latest version of the Arduino IDE and Java on Mac OS 10.9.

Whether I try to compile (no Arduino connected) or try to upload the code, the error appears.

Below is the complete error message.

Arduino: 1.8.10 (Mac OS X), Board: "Arduino/Genuino Uno"

dyld: Symbol not found: _unlinkat
Referenced from: ***/

Error compiling for board Arduino/Genuino Uno.

Does anyone know what is wrong?

I would recommend rolling back to Arduino IDE 1.8.9. There seems to be some bugs with the version of arduino-builder used by Arduino IDE 1.8.10. I think they will have it all fixed up for the Arduino IDE 1.8.11 release.

You can download Arduino IDE 1.8.9 here:

That did the trick!

I installed the older version and was able to compile the sample code with no errors.

Thanks for the help!
