My Arduino IDE does not compile any project since I updated from Mac OSX 10.6.8 to 10.11.6. I even tried reinstalling and also manually installing the original AVR-toolchain. But the behaviour did. Jan 08, 2012.
Great news, Makers! We’re excited to announce the immediate availability of the Arduino IDE 1.6.10, AVR core 1.6.12 and SAM core 1.6.9.
The most notable feature of this release is the introduction of an up-to-date bundled toolchain for AVR containing the latest goodies from Atmel, GCC and AVRDUDE devs.
Feb 28, 2020. Sep 24, 2020. Great news, Makers! We’re excited to announce the immediate availability of the Arduino IDE 1.6.10, AVR core 1.6.12 and SAM core 1.6.9. The most notable feature of this release is the introduction of an up-to-date bundled toolchain for AVR containing the latest goodies from Atmel, GCC and AVRDUDE devs.
Thanks to LTO (Link Time Optimization), making your sketches smaller and faster is now only a push of the “Compile” button away.
The AVRDUDE update brings out-of-the-box support for a wide range of microcontrollers and debuggers, making it is as simple as possible to deploy. (For example, problems with Gatekeeper on Mac and dependencies on Linux are a thing of the past.)
Likewise, the builder has received the love it deserves and some of its shortcomings are gone forever. You’ll never have to worry again about encountering weird errors if you need to use C++ advanced libraries.
All these improvements have been shared with Arduino Create, our cloud-based IDE. Check it out if you’ve never tried it, or test out these enhancements if you’re already an active user! ?
Of course, we also fixed some corner cases for user experience, so now we have a better error reporting when the upload fails and a [nicer] way to include libraries containing lots of header files.
What’s more, we have gone ahead and developed a new firmware and certificate updater for MKR1000 / WiFi101 Shield users–it’s bundled with the IDE and available as a plugin for older installations.
Our community effort continue to grow well with tons of bugfixing, proposals, and libraries added to the Library Manager. As you can imagine, this makes us extremely happy–thank you all for the contributions!
As usual, be sure to check the entire changelog for a complete list of changes and credits. Don’t forget to report any issue you may find, either on GitHub or on the Arduino Forum–your help is very much appreciated.
Go ahead and download IDE 1.6.10! Happy hacking!

![]() Getting Started w/ Arduino on Mac OS X
This document explains how to connect your Arduino board to the computer and upload your first sketch.
On this page.. (hide)
1 | Get an Arduino board and USB cable
In this tutorial, we assume you're using an Arduino Uno, Arduino Duemilanove, Nano, or Diecimila. If you have another board, read the corresponding page in this getting started guide.
You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. (For the Arduino Nano, you'll need an A to Mini-B cable instead.)
2 | Download the Arduino environment
Get the latest version from the download page.
The disk image (.dmg) should mount automatically. If it doesn't, double-click it. It should look like the following image.
3 | Install the Software
Copy the Arduino application into the Applications folder (or elsewhere on your computer). If you're using an Arduino Uno or Mga 2560, you don't have any drivers to install. Skip ahead to the next step.
If you're using an older board (Duemilanove, Diecimila, or any board with an FTDI driver chip that looks like this:
you will need to install the drivers for the FTDI chip on the board. Double-click the FTDIUSBSerialDriver_10_4_10_5_10_6.mpkg icon and follow the instructions in the installer. You'll need to restart your computer after installing the drivers. (The latest version of the drivers can be found on the FTDI website.)
4 | Connect the board
The Arduino Uno, Mega, Duemilanove and Arduino Nano automatically draw power from either the USB connection to the computer or an external power supply. If you're using an Arduino Diecimila, you'll need to make sure that the board is configured to draw power from the USB connection. The power source is selected with a jumper, a small piece of plastic that fits onto two of the three pins between the USB and power jacks. Check that it's on the two pins closest to the USB port.
Connect the Arduino board to your computer using the USB cable. The green power LED (labelled PWR) should go on.
If you're using the Arduino Uno or Arduino Mega 2560, a dialog box will appear telling you that a new network interface has been detected. Click 'Network Preferences..', and when it opens, simply click 'Apply'. The Uno or Mega 2560 will show up as 'Not Configured', but it's working properly. Quit System Preferences.
5 | Launch the Arduino application
Double-click the Arduino application.
6 | Open the blink example
Open the LED blink example sketch: File > Examples > 1.Basics > Blink.
7 | Select your boardArduino Download For Mac
You'll need to select the entry in the Tools > Board menu that corresponds to your Arduino.
Selecting an Arduino Uno
For Duemilanove Arduino boards with an ATmega328 (check the text on the chip on the board), select Arduino Duemilanove or Nano w/ ATmega328. Previously, Arduino boards came with an ATmega168; for those, select Arduino Diecimila, Duemilanove, or Nano w/ ATmega168. (Details of the board menu entries are available on the environment page.)
8 | Select your serial port
Select the serial device of the Arduino board from the Tools > Serial Port menu. On the Mac, this should be something with /dev/tty.usbmodem (for the Uno or Mega 2560) or /dev/tty.usbserial (for older boards) in it.
selecting an Uno, Mega2560, or newer board
selecting an older FTDI-based board
Arduino For Mac9 | Upload the program
Now, simply click the 'Upload' button in the environment. Wait a few seconds - you should see the RX and TX leds on the board flashing. If the upload is successful, the message 'Done uploading.' will appear in the status bar. (Note: If you have an Arduino Mini, NG, or other board, you'll need to physically present the reset button on the board immediately before pressing the upload button.)
Arduino Download Mac 10.6 Download
A few seconds after the upload finishes, you should see the pin 13 (L) LED on the board start to blink (in orange). If it does, congratulations! You've gotten Arduino up-and-running.
If you have problems, please see the troubleshooting suggestions.
