 # micro:bit uploader for OS X
 ![](Microbit Uploader/Assets.xcassets/AppIcon.appiconset/icon_256x256.png)
 This project is a clone of the [Windows
 uploader](https://codethemicrobit.com/uploader), but for OS X. Once launched,
 the app runs in your menu bar and will automatically deploy any HEX files to
 your `micro:bit`. Like the Windows version, it is compatible with any browser
 that can run [codethemicrobit.com](http://codethemicrobit.com).
 ## Install the built version
 1. Download the latest `.zip` release from the `Release` directory
 2. Unzip it
 3. Drag `Microbit Uploader` to your Applications folder and launch it
 ## Building
 To build the project you'll need a copy of OS X 10.11 or higher and Xcode 8 or
 higher (you may be able to build on earlier OSes or versions of Xcode, but this
 remains untested). Once you have a development environment set up, just build
 and run `Microbit Uploader.xcodeproj`.
 ## Distributing
 1. Open the Xcode project
 2. Product > Archive
 3. Export:
    ![Export](Graphics/export.png)
 4. You will then have the option of either signing or not-signing the
   application:
    a) If you have an Apple developer account, select 'Export a Developer
       ID-signed Application'
    b) If you don't have a developer ID, select 'Export as a macOS App'
 5. Zip the produced app and upload to CDN or equivalent

 ### @description A Blocks / Javascript code editor for the micro:bit, a pocket-size computer with 5x5 display, sensors and Bluetooth.
 The [BBC micro:bit](https://www.microbit.co.uk) is a [pocket-size computer](/device) with a 5x5 display of 25 LEDs, Bluetooth and sensors that can be programmed by anyone.
 The BBC micro:bit was made possible by many [partners](https://www.microbit.co.uk/partners).
 The micro:bit provides an easy and fun introduction to programming and making – switch on, program it to do something fun – wear it, customize it.
 Just like Arduino, the micro:bit can be connected to and interact with sensors, displays, and other devices.

 ## [Compile and Flash: Your Program!](/device/usb)
 When you have your code ready, you connect your micro:bit to a computer via a USB cable, so it appears as a mounted drive (named MICROBIT). 
 Compilation to ARM thumb machine code from [Blocks](/blocks) or [JavaScript](/javascript) happens in the browser. You save the ARM binary 
 program to a file, which you then copy to the micro:bit drive, which flashes the micro:bit device with the new program.
 ## Simulator: Test Your Code
 You can run your code using the micro:bit simulator, all within the confines of a web browser. 
 The simulator has support for the LED screen, buttons, as well as compass, accelerometer, and digital I/O pins.

 #### Chrome
 Your `.hex` file appears as a download at the bottom of the browser. Click on
 the arrow next to the name of the file and then click **Show in folder**.
 ![](/static/mb/device/usb-windows-chrome.png)
 Drag and drop the `.hex` file from the download folder onto the `MICROBIT` drive.
 #### Firefox
 A window will appear asking whether you want to save or open the `.hex` file.
 Select **Save File** and then select **OK**.
 ![](/static/mb/device/usb-windows-firefox-1.png)
 The file will then appear in your downloads in the top right of your browser.

 the browser. Click on the small arrow and select **Show in Finder**. This will
 show the file in your download folder. Drag and drop the file onto your
 `MICROBIT` drive.
 ![](/static/mb/device/usb-osx-chrome.png)
 ## Step 3: Transfer the file to your micro:bit
 * Once you've found the folder containing your `.hex` file, drag and drop it
    onto your `MICROBIT` drive
 * If you're using Windows, you can use **Send to** as described below 
 * The LED on the back of your micro:bit flashes during the transfer (which 
    should only take a few seconds).
 * Once transferred, the code will run automatically on your micro:bit. To rerun
   your program, press the reset button on the back of your micro:bit. The reset 
   button automatically runs the newest file on the micro:bit.
 **Send to**: If you're using Windows you use *Send to* in File Explorer:
 - In File Explorer, right-click on the hex file (created in Step 2 above), choose **Send to**, and then **MICROBIT**.
 ![](/static/mb/device/usb-windows-sendto.jpg)
 By copying the script onto the `MICROBIT` drive, you have programmed it into the
 flash memory on the micro:bit, which means even after you unplug the micro:bit,
 your program will still run if the micro:bit is powered by battery.
 ## Troubleshooting
 You can’t drag and drop more than one hex file at once onto your micro:bit. If
 you try to drag and drop a second hex file onto your micro:bit  before the first
 file has finished downloading, then the second file may fail in different ways.
 When the first program has been written to the micro:bit, the drive will
 disengage. If you drag and drop a second file at this point it may not find the
 drive and the second write will fail.
 The errors may look like this:
 **Windows**
 ![](/static/mb/device/usb-windows-copy-file-error.jpg)
 **Mac**
 ![](/static/mb/device/usb-osx-copy-file-error.png)
 Or it may appear that there are two hex files on your micro:bit so the micro:bit
 won’t be able to run multiple files. To rectify this, unplug your micro:bit and
 plug it in again. Make sure that your micro:bit  appears as `MICROBIT` and not
 `MAINTENANCE`.

 # Uploading from Safari for Mac
 While you're writing and testing your programs, you'll mostly be [running them
 in the simulator](/device/simulator), but once you've finished your program you
 can **compile** it and run it on your micro:bit.
 The basic steps are:
 1. Connect your micro:bit to your computer via USB
 2. Click **Download** and download the `.hex` file
 3. Copy the `.hex` file from your computer onto the micro:bit drive
 ## Requirements
 You need the following things to transfer and run a script on your micro:bit:
 * A-Male to Micro USB cable to connect your computer to your micro:bit. This is
    the same cable that is commonly used to connect a smart phone to a computer.
 * A PC running Windows 7 or later, or a Mac running OS X 10.6 or later
 ## Step 1: Connect your micro:bit to your computer
 First, connect the micro:bit:
 1. Connect the small end of the USB cable to the micro USB port on your micro:bit.
 2. Connect the other end of the USB cable to a USB port on your computer.
 Your computer should recognise your micro:bit as a new drive. On computers
 running Windows, `MICROBIT` appears as a drive under Devices and drives. On a Mac
 it appears as a new drive under Devices.

 ## Step 2: Download your program
 1. Open your project on [codethemicrobit.com](https://codethemicrobit.com)
 2. Click **Download**
 3. When prompted, choose to **save** the compiled file onto your computer. The
   prompt will be different depending on which browser you are using, or
   whether you are using a Windows computer or a Mac
 When you select **Download** in Safari a file called `Unknown` will be
 downloaded into your Downloads folder. Open your Downloads folder and drag and
 drop the file onto your `MICROBIT` drive, under Devices:
 ![](/static/mb/device/usb-osx-dnd.png)
 ## Step 3: Transfer the file to your micro:bit
 * Once you've found the folder containing your `.hex` file, drag and drop it
    onto your `MICROBIT` drive
 * The LED on the back of your micro:bit flashes during the transfer (which 
    should only take a few seconds).
 * Once transferred, the code will run automatically on your micro:bit. To rerun
   your program, press the reset button on the back of your micro:bit. The reset 
   button automatically runs the newest file on the micro:bit.
 By copying the script onto the `MICROBIT` drive, you have programmed it into the
 flash memory on the micro:bit, which means even after you unplug the micro:bit,
 your program will still run if the micro:bit is powered by battery.

 # Troubleshooting Transfer
 You can’t drag and drop more than one hex file at once onto your micro:bit. If
 you try to drag and drop a second hex file onto your micro:bit  before the first
 file has finished downloading, then the second file may fail in different ways.
 When the first program has been written to the micro:bit, the drive will
 disengage. If you drag and drop a second file at this point it may not find the
 drive and the second write will fail.
 The errors may look like this:
 **Windows**
 ![](/static/mb/device/usb-windows-copy-file-error.jpg)
 **Mac**
 ![](/static/mb/device/usb-osx-copy-file-error.png)
 Or it may appear that there are two hex files on your micro:bit so the micro:bit
 won’t be able to run multiple files. To rectify this, unplug your micro:bit and
 plug it in again. Make sure that your micro:bit  appears as `MICROBIT` and not
 `MAINTENANCE`.

 # Raspberry Pi and Raspbian
 It is possible to run the web editor or [command line interface](/cli) from Raspbian on Raspberry Pi 2 or 3.
 ## Web editor
 The web editor requires to install IceWeasel (Firefox) as the built-in browser cannot handle it.
 ```
 sudo apt-get install iceweasel
 ```
 Once installed simply navigate to https://codethemicrobit.com or type
 ```
 firefox https://codethemicrobit.com
 ``` 
 ## Command line
 The PXT command line also works on Raspbian and allows to run a local server and/or edit programs from any text editor.
 * Node.JS 6.0 needs installed
 To install all the tools,
