Eclipse cant be opened on mac m1

Question

I have installed eclipse aarch64 based on my mac m1. it was working fine. later i stopped using it for few days but i was just opening and closing it just to make sure it is not crashing as it used to happen with x64 version. Now even with aarch it is crashing. As soon as i open it via launch pad it says 'The apllication 'Eclipse'can't be opened.

Here are the details of eclipse and jdk version that i am currently using. Eclipse: eclipse-java-2021-12-R-macosx-cocoa-aarch64 Jdk: jdk-17_macos-aarch64_bin

That's the .dmg file, not the Eclipse Installer, right? You put the .dmg file where? – Relucent

'Ts right under my system's downloads folder – Tumbledown

That's might be the issue. – Relucent

where should be placing the .dmg? – Tumbledown

Does dragging the .dmg file to your Applications folder work? – Relucent

I've just had the same problem on the second launch of Eclipse from a fresh installation. The solution was to re-sign the app with an ad-hoc signature:

sudo codesign --force --deep --sign - /Applications/Eclipse.app

Have you tested this with all kinds of installations? Via Eclipse Installer and via a .dmg file? With all Eclipse IDE packages, each as x86_64 and AArch64? With different Eclipse versions? With different installation directories? Or do you assume it's the same and assume your answer applies to all kinds of installations? If yes, please say so and tell which one of those you have tested. – Relucent

Worked for me! M1 Monterey Eclipse Version: 2021-12 (4.22.0) aarch64 – Clabber

Worked for me as well with the same version commented above - seems to be a weird bug that needs reporting. – Hanks

This worked for me on M1, os 12.2.1 – Ngo

The above answer by @Timm worked for me, even though I don't know the basis of neither the problem nor this solution. I am on a mac mini with M1 chip, and Sonama v14.6.1 – Lachrymal
