MAT doesn't respond to any mouse click on Mac OS [message #1779229]

OS version: 10.13.2 (17C88)
MAT version: 1.7

Clicking on mat doesn't get any response on UI.
Really cannot do nothing now.

I had the same issue and worked around it by replacing MAT's SWT version with a later one.

Grabbed this one

Then replaced MAT's, being careful to use the same name like so:

mv /Users/cgrinds/Downloads/swt-4.7.1a-cocoa-macosx-x86_64/swt.jar /Users/cgrinds/mat1.7.app/Contents/Eclipse/plugins/org.eclipse.swt.cocoa.macosx.x86_64_3.104.2.v20160212-1350.jar

Thanks, Chris! This totally worked for me with macOS High Sierra.

This didn't work for me. When I replaced my org.eclipse.swt_3.104.2.v20160212-1350.jar, it reports the following error on launch:

org.osgi.framework.BundleException: Error starting module.

It seem that another package org.eclipse.ui.workbench_3.107.1.v20160120-2131.jar (which does exist in the same directory) is incompatible with this newer version of SWT.

Shall I replace the org.eclipse.ui.workbench with a new version too? Which version? Could you please give me some suggestion on how to find this out?

Thanks.

Had the same error with the latest snapshot, workaround seems to work fine with the 1.7.0 release.

The workaround noted is correct in spirit but can't work in practice because the linked SWT jar file does not have an OSGi Bundle Manifest and while it contains that SWTError class it does not export that package.

I made this work by downloading a current Eclipse IDE for MacOS, taking the org.eclipse.swt.cocoa.macosx... jar from there and then copying that over the swt jar in the MAT installation.

That works for me.

Worked for me too, things are now clickable.

cp swt-4.7.1a-cocoa-macosx-x86_64/swt.jar  .
mv swt.jar mat.app/Contents/Eclipse/plugins/org.eclipse.swt.cocoa.macosx.x86_64_3.104.2.v20160212-1350.jar
