Greetings, my fellow human beings. I am now on the other side of the globe in Madison, Wisconsin. Now that I've settled down I'm hoping to continue pushing out content. I recently bought a MacBook Air, having never used a Mac in my life, and today I'll talk about how to install Eclipse on OS X 10.9.4. There wasn't a one-stop recipe when I had to do this last week, but I've written one here for you!
  1. Download the Eclipse installer from the Eclipse website [link]. For me, this is Eclipse Standard 4.4 Mac OS X 64-bit.
  2. Unzip the .tar.gz file. You should see a folder named 'eclipse'. Move this folder to the Applications folder of your Mac.
  3. Double-click the file 'Eclipse' in the eclipse folder to launch Eclipse.
At this point, you may see a message saying "Version 1.6.0_65 of the JVM is not suitable for this product. Version: 1.7 or greater is required.". To do that, follow the following instructions.
  1. Download the latest Java development kit from Oracle website [link]. At the time of writing, that is jdk-8u20-macosx-x64.dmg.
  2. Double-click the .dmg file and follow the instructions to install the JDK.
  3. You should be able to launch Eclipse now - again, by double-clicking the file 'Eclipse' in the eclipse folder.
I hope that works for you! We live in exciting times.
