For about 3 months, the Java update flashes for me to install. I give permission to install it and it always shows that the update download has failed to install. I don’t know how to fix the problem and I don’t know what Java is or does, but my securtiy system has OK’d it as safe. A: If you have not yet installed Apple’s Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in. There can be multiple JDKs installed on a system – as many as you wish. Apple is doing this to satisfy the security needs of the customer but Java just gets worse with each release. Apple is still waiting for Sun to make a version of Java that does not have Semi truck size security holes in it. Sun makes Java not Apple, Denmark needs to change who they yell at. I’m on a Mac Mini mid 2011 and was running El Capitan until I installed Sierra. When I try to open InDesign, I get this message: ’To open Adobe InDesign CS5.5 you need to install the legacy Java SE 6 runtime. Click ’more info’ to visit the legacy Java SE 6 download website.’ I’m about the MOST untechnical human on Earth and don’t understand this.
Note that installing the JDK on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version.JDK 7 Installation InstructionsInstallation of the 64-bit JDK on Mac Platforms
When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.
Depending on your processor, the downloaded file has one of the following names:
*jdk-7u<version>-macosx-amd64.dmg
*jdk-7u<version>-macosx-x64.dmg
Where <version> is 6 or later.
1. Download the file. Before the file can be downloaded, you must accept the license agreement.
2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.
3. A Finder window appears containing an icon of an open box and the name of the .pkg file Double click the package icon to launch the Install app.
4. The Install app displays the Introduction window. Click Continue.
4a. Note that, in some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the continue button. Click Continue.
5. The Installation Type window appears. Click Install.
6. A window appears which says ’Installer is trying to install new software. Type your password to allow this.’ Enter the Administrator login and password and click Install Software.
7. The software is installed and a confirmation window appears. Click the ReadMe for more information about the installation.
After the software is installed, delete the dmg file if you want to save disk space.Determining the Default Version of the JDK
A: If you have not yet installed Apple’s Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.
There can be multiple JDKs installed on a system – as many as you wish.
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.0_06. For example:
To run a different version of Java, either specify the full path, or use the java_home tool:
For more information, see the java_home(1) man page.Uninstalling the JDK
To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.
Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*
For example, to uninstall 7u6:
Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.Copyright © 1993, 2014, Oracle and/or its affiliates. All rights reserved.
A lot of MacOS users are complaining that they can’t launch a JAR file in Mac OS X 10.14.3 (Mojave). One user even complained that whenever he clicks on the “.jar file, or manually select the Jar Launcher from a right-click on the file, the file makes an animation like it’s going to open, but nothing happens.”
Other users complain that the worst thing about the “Jar Launcher not working” issue is that there are no elegant solutions on how to fix it. This, they say, is a cause of a lot of frustrations. In this article, we will help troubleshoot the “MacOS Mojave won’t launch jar file” bug and in the process help the brave souls who are battling this macOS malfunction all on their own.
Some of the solutions we have listed here have been endorsed by Apple, but most are sourced from people who have found a way to work around the problem. Hopefully, they will be of help to you.Clean Your Mac
Before we get started, we recommend that you clean your computer with a Mac cleaning tool, preferably a premium utility software. This will remove the clutter and digital debris that has accumulated in your system over time. It will, in other words, restore your Mac in fine fettle, something necessary if you are going to troubleshoot some issues on your computer.What Is Jar Launcher?
Jar Launcher is the program that is responsible for launching Java JAR files on macOS. The launcher, however, does not execute the files as this role is reserved for the Java Virtual Machine. The launcher is located in /System/Library/CoreServices/Jar Launcher.app.
Thus, any problems that you might be experiencing while trying to launch .jar files may result from the launcher itself or the Java Virtual Machine. It could also be likely that Mojave has its issues that only Apple can fix.
So, how do you resolve problems associated with the Jar Launcher and JVM?1. Install the Java for Mac OS X 10.6 Update 17
Installing the latest Java update for macOS will fix any issues that you might be experiencing, while trying to open .jar files. According to Apple, the update delivers an improved security, compatibility, and reliability by updating Java SE 6 to 1.6.0_65. This update also enables per-website control of the Java plug-in within Safari 5.1.9 or later.
To check whether your Mac is running on this latest version, go to Applications > Utilities > Terminal and type java-version, and then press Enter. Doing this should reveal the following message:
java version “1.6.0_51”
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-10M4509)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
To download this latest update from Apple, click here. For the most recent Java, download here. After completing the downloads and installations, check if the problem has been resolved.
If the version of Java installed on your computer is the latest, and you still experience speed issues, there is a way around that. Go to Applications -> Utilities -> Java Preferences > Network tab. From here, unflag “Keep temporary files for fast access.” This will resolve Java speed issues. This fix will, however, only work if you don’t have space constraints on your computer. As a general rule, your computer’s hard drive should not be more than 85% full. If you don’t know how to free memory on your Mac, read this guide.2. Check Your .Jar File and Workspace
If your .jar is not properly constituted, it may result in failures when you want to launch the files, even if you know how to open a jar file on Mac. That is why it is essential to double-check your file for any errors before trying to run it.
You also need to check whether you have Java installed on your machine. To do this, go to Applications > Utilities > Terminal, and type java -jar /path/to/your/app.jar
If you don’t have Java installed on your device, then you need to download the latest version.
Your .jar files may also be failing to launch because your workspace is corrupted. To make sure that this is not the case, copy the code and paste it onto a new workspace, and see if this resolves your problem. Some users have managed to solve the “Mojave won’t launch jar file” issue this way.3. Run the .jar File in the Console
Running the .jar file directly in the Console will result in an error message that contains the reason your file does not run and tips on how to debug the problem. If you can check the error message and apply the recommended fixes, this might help solve your problem.4. Run the .jar file from the Terminal
If the .jar file that you want to run is properly constituted, then running it from the Terminal should work just fine. Here’s how to run a .jar file from the Terminal:
*Press the Control + Option + Shift + T keys to open a new Terminal.
*Type $ java -jar filename.jar and hit Enter.
Check if your problem has been resolved.
Hopefully, the above three solutions have helped resolved your problems with launching.jar files on MacOS Mojave. The best solution among the three is to download the patch from Apple because it seems that the company has at least recognized that the bug stems from their side.Java Won’t Download Windows 10
