to finish. - When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21". - Click "Install". - Wait for installation to finish. - Click "Close". Due to a [bug](https://github.com/arduino/Arduino/issues/7973), this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE. If you have **File \> Preferences \> Check for updates on startup** checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again. Alternate workaround: One of the Arduino developers recently worked on this and claims to have fixed it. There is a special beta testing hardware package you can install via the Arduino IDE's Boards Manager that has the fix: - (In the Arduino IDE) File \> Preferences - In the "Additional Boards Manager URLs" field, enter: [http://downloads.arduino.cc/packages/package\_avr\_7.3.0\_index.json](http://downloads.arduino.cc/packages/package_avr_7.3.0_index.json) If you already have an additional Boards Manager URL in that field, you can separate multiple URLs with commas or click the button on the right side of the field to open a dialog that allows you to add each on its own line. - Click "OK" - Tools \> Board \> Boards Manager - Wait for the downloads to finish - Click on "Arduino AVR Boards by Arduino" - Click the "Update" button. - Wait for the update to finish. - Click "Close". ---
