After upgrading to macOS Big Sur I couldn’t run Oracle SQL Developer. I got the following error:
The application “SQLDeveloper.app” can’t be opened
To resolve this issue I got help from Kris Rice and Niels de Bruijn. The issue is caused by Apple and the Java applet plugin.
Free electrical panel software. Here’s how I got SQL Developer working:
Oracle Sql Developer
Sql Developer For Macbook
Oracle SQL Developer is a free graphical tool that enhances productivity and simplifies database development tasks. Programs for query ″sqldeveloper mac″ Oracle SQL Developer. Then just open SQL Developer, go to your OS settings where the Display preferences are, and as you adjust, you should see SQL Developer’s UI change as well. I tried this on latest OS X with a 4k Dispay and Windows 10 with a standard ‘regular’ monitor.
List your Java Versions
The one that caused the problem is the
'Oracle Corporation' - 'Java' /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home and you’ll need to remove it.
Remove the Applet Plugin
If you run SQL Developer now it should work. I’m not sure about the side effects of removing this Java applet plugin. If I find it to be critical to other things I’ll be sure to update this post.
