I've been running Eclipse Mars on Mac OS X 10.7.5 successfully for a few years. However as I'd like to upgrade to Java 10 soon I tried to update to Eclipse Photon last week. The installer however crashed immediately. I've been googling it for a while but couldn't find anything so I created bug report. There I was told that Eclipse Photon won't run on anything lower than OS X 10.11. However, I would be able to run Eclipse Oxygen successfully when replacing the launcher with the Neon.3 launcher.

Eclipse.org went with a mountain peaks as the website theme for the release of Oxygen.I like it; lower Oxygen concentration when hiking at that altitude. And unlike the neon lights, it wasn’t distracting. The matrix comparing the packages is still clear. The Java version is a subset of the Java EE version. The bundle contains the lastest release version of the Scala IDE for Eclipse and it comes pre-configured for optimal performance. Is available for Scala 2.12 (with support for Scala 2.10 and 2.11 projects in the same workspace) and is based on Eclipse 4.7 (Oxygen). Windows 64 bit. Mac OS X Cocoa 64 bit. Free bridge games for mac. Linux GTK 64 bit.

Point is, how do I replace that launcher? Also, I was wondering if I can run Eclipse Photon on OS X 10.9.5. I may be upgrading to that version by the end of this year (I have my reasons to not upgrade to 10.11 in the near future). Thanks in advance.

I've found the solution myself. Unfortunately, it is not possible to run Eclipse Photon on Mac OS X 10.7.5.

Officially, Eclipse Oxygen is not supported either and it will crash when trying to open it. It is however possible to run Eclipse Oxygen on Mac OS X 10.7.5 by replacing the launcher with the Neon launcher. • You will need to download both the Eclipse and installer. • Run the Neon installer and install Eclipse Neon.

• Right click the Oxygen installer -> Show contents and do the same for the Neon installer. Then replace Contents/MacOS/eclipse-inst from Oxygen with the Contents/MacOS/eclipse-inst file from the Neon installer. • You can now successfully open the Oxygen installer and install Eclipse Oxygen. • After installing it, open the contents of Eclipse.app for both Oxygen and Neon. Then replace Contents/MacOS/eclipse in Oxygen with Contents/MacOS/eclipse from Neon. • You can now remove Eclipse Neon and successfully open Eclipse Oxygen.

Apple’s Xcode development system is superb for developing applications, but sometimes you just want to write C or C++ code for research or school. Composing a serious chunk of code with vi is no longer acceptable,* so users in this frame of mind are now using Eclipse, a modern IDE, that’s also free. Here’s how to get gcc without installing Apple’s Xcode and then install Eclipse for C/C++ programming.

What’s the Motivation? At work recently, my wife was chatting with a colleague who was taking his first C++ class. She taught him how to use Eclipse on a Mac, even though he resisted at first. However, later, he came back and commented that the other students were trying to manage ever increasingly complex projects with the vi editor. It was taking them four, six, or even 20 hours in some cases to complete their homework each week. He finished his, typically, in 30 minutes. That’s the power of an IDE with a modern debugger.
