My current operating system is:
macOS High Sierra version 10.13.1

My current installed version of Java is:
java version "1.8.0_151":
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

I've downloaded and unzipped the following version of Eclipse
eclipse-jee-oxygen-M2-macosx-cocoa-x86_64.tar

I've then created a folder called Java on my desktop and unzipped the file in the folder. When I click on the eclipse shortcut in the unzipped Eclipse Oxygen file i'm getting the following error Message - "The application "Eclipse" cannot be opened

I've installed all the above Windows versions on my windows laptop and it all works fine. However, i want to code on my Mac. Please can you advise on what the problem is and how i can fix it.

I've looked at other threads but none seem to have the same issue. I've attached screenshots of the files i've downloaded.

Thanks in advance for your help.

Hi Gareth,

The file you downloaded for Mac should have been a "DMG" file, not an archive. You can simply "run" that file to install Eclipse in the Mac's Applications folder. You do not need to unzip that file...

Hi Gareth,

I just saw your post. I just posted as well regarding problems with Eclipse under macOS 10.13.1 (still waiting for it to appear in the forum). I'm having trouble with the JRE part - in particular, getting the right version in place. You seem to have managed that - can you tell me where you got it?

Many thanks in advance,
Matt
