This article addresses ENVI/IDL's current dependency on legacy Java 6 libraries. Java 6 is used by the IDL Development Environment, by ENVI, bridge processes, as well as some newer graphics routines. L3Harris Geospatial Development is working to move off this legacy Java 6 dependency, but for now you will require this version to be installed on your MacOS.
Java 6 cannot currently be installed on macOS 10.15 Catalina because there is a newer version of Java installed on the system. Attempts to reinstall legacy Java libraries upon upgrade of the OS may result in errors restricting installation. Some users have also experienced their previously existing legacy Java libraries have been moved or quarantined. This renders ENVI/IDL unusable. If you are seeing warning icons indicating you cannot place Java onto the disk because a newer version of the package is already installed, such as:
Or if you have installed IDL 8.7.3 or ENVI 5.5.3, and when you go to double-click on an IDL or ENVI icon within Finder, you receive an error, such as:'To open "idle.darwin.x86_64" you need to install the legacy Java SE 6 runtime.'
We have found a workaround provided below that has alleviated this issue for some users. This is an unofficial workaround and users should be aware to attempt this with knowledge that it is at their own risk. The workaround creates an AppleScript that removes the installation limits from Java for macOS 2017-001. The AppleScript creates a new modified Java installer package file, JavaPackageforModifiedforCatalina.pkg which should work for installation of Java 6. (NOTE: this article assumes the user has obtained in installed the legacy Java for OS X 2017-001 from Apple Support):
Click Continue and install - you will be prompted to enter your password. Once installation is successful, close the installer. This should work to enable adding legacy Java onto the Catalina Mac OS device, ultimately enabling you to use ENVI/IDL. A reboot should not be required upon completing the steps above.
NOTE: If issues persist and you are still unable to access ENVI/IDL, you may also need to reinstall XQuartz 2.7.11 after upgrading to macOS 10.15 Catalina. The suggested workflow can be found in this help article. Basic steps are as follows:
This problem occurs because these apps (Adobe CS5, CS5, etc.) are relying on Java 6. Mac OS X Yosemite (and the newer versions) are having a later version of Java Runtime (SE 8.0). However, Java Runtime is not backward compatible. So, even when the operating system have installed Java Runtime 8, it will NOT run apps that rely on Java Runtime 6. Here is how to get Java 6 on your Mac.
As the error indicates, the particular app relies on Java 6 to function correctly. Since the newer version of Mac comes installed with Java SE 8 which is not backward compatible, the programs will end up displaying the aforementioned error.
Some legacy apps for Mac may require Java SE 6 even though Mac OSX and above comes installed with Java SE 8 out of the box. By following the steps in this article you can install Install Java SE 6 on Mac.
Did you figure this out? I am having the same issue! I uninstalled the newer version of Java and have been trying to download and install the SE6 but it keeps saying a newer version is installed, but its gone.
Thank you! After searching over an hour, most of the other answers pointed to a page mentioning that SE 6 is very old and therefore not available, I found your answer, downloaded that Java installer and now I can continue using Adobe Illustrator CS3. Thank you again
JesusRZ, which Java installer did you download? I'm having the same issue as most people in this discussion. I'm getting the same error message and I'd like to run my Adobe Dreamweaver CS5. Thanks for your help!
You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.
To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.
If you have not yet installed Apple's Java 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 application. See Notes for Users of macOS That Include the Apple Java 6 Plug-in.
You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 9 Minor 1, Security 1, Patch 1, then you see a string that includes the text 9.1.1.1. For example:
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 that you perform an update of the OS.
Do not 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 that you perform an update of the OS.
If you only plan to run Java applications, then install the Java Runtime Environment (JRE). The JRE is also referred to as Oracle Java. After you have installed the JRE, you can start Java applets and applications by double-clicking JAR files, JNLP files, and by using the browser. Note that 32-bit browsers, such as Firefox in 32-bit mode, and Chrome, are not supported by the JRE.
If you have not yet installed Apple's Java macOS 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences application. See Notes for Users of macOS That Include the Apple Java 6 Plug-in.
The Java for macOS 2012-006 update from Apple uninstalls the Apple-provided Java applet plug-in from all web browsers. You can download the latest version of Java from Java SE Downloads, which has improved security, reliability, and compatibility.
Some applications use /usr/bin/java to call Java. After installing Java for macOS 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java-related command-line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.
There is an important difference about the installation of Oracle Java (both JRE and JDK) that you should be aware of. The Java Preferences application, started by selecting Applications and then Utilities, is part of Apple's implementation of Java. After Apple no longer distributes Java as part of their release, the Java Preferences application is retired.
Under Apple's implementation of Java, it was possible to have multiple JREs installed. The Java Preferences application was used to determine the first compatible version that would be used. You can change the default JRE by starting Java Preferences and then dragging Java SE 9 to the top of the list.
The Java Preferences window contains a list of installed JREs. Java applications and command-line tools use the listed order to determine the first compatible version to use. The Vendor column indicates whether the Java release is supplied by Apple or Oracle. The Version column specifies the version of Java that is installed.
You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 15 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 15. For example:
UPDATE: After removing Java 1.6 from my machine, the next time I ran PhpStorm, it told me it needed to download and install the Java SE 6 runtime. Afterward, the /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK link was reset to /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents. So it seems that the 1.6 JDK (or at least the JRE portion of it) may keep coming back, depending on other apps you use.
In order to run properly, the latest version(V1.3.6) of Focusky Presentation Maker for Mac requires Java 1.6 to be installed on Mac computer. This tutorial will teach you how to install Java on your Mac OS.
Since the latest Java you can get from Apple update is in version 1.6, we can directly install Java by using the system utilities. Please follow below guide to learn how to do this in your Mac computer.(Please make sure your Internet connection works)
Note: In Dreamweaver 2014, the prompt does not appear when you launch Dreamweaver. However, you are prompted to install Java SE 6 runtime while logging in to PhoneGap Build service (Site > PhoneGap Build Service > PhoneGap Build Service).
Important: Ensure that you install Java SE 6 Runtime only by clicking Install in the pop-up window. If you install Java SE 6 or 7 Runtime through any other means (for example, by directly accessing Java.com), Dreamweaver could still display the prompt. 2ff7e9595c
