I’m using a MAC with OS X El Capitan 10.11.6, 2,8 GHz Intel Core 2
Duo with
4 GB RAM.
I know it is an older system but work fine and I would not throw it
away as it runs still fin bought is January 2008.
I learned it is a simple problem Espressif could solve by activating
a simple switch. Do somw know a solution beside those on the internet
I apreciate any hint
Thanks
Rainer

Hi Rainer,
For what you told me in your question, sounds like you already read this GitHub issue: https://github.com/espressif/arduino-esp32/issues/764
That error seems to happen on older Mac computers and according to some readers on GitHub the toolchain installation is not fixed, yet.
Sounds like the solution is to build the Xtensa toolchain on your Mac from strach, but I don’t have any instructions on that exact subject: https://github.com/espressif/esp-idf/issues/1488
The comment by wulph111 might point you in the right direction, but you might need to build the Xtensa toolchain from scratch: http://esp-idf.readthedocs.io/en/latest/get-started/macos-setup-scratch.html
I hope that helps!
