Java For Mac Legacy: How to Switch Between Different Versions of Java on Your Mac

The link in your post no longer seems to work. There are some YouTube videos showing the exact same link used to correct the problem of legacy Adobe CS programs not being able to run, however the download button no longer seems to function.

Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion.

cmd: /usr/libexec/java_home -Voutput of above cmd may look like below, (in my side it shows below info as those were my existing items when this answer was written):Matching Java Virtual Machines (4): 14.0.1, x86_64: "OpenJDK 14.0.1" /Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home 1.7.0_80, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home 1.6.0_65-b14-468, x86_64: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 1.6.0_65-b14-468, i386: "Java SE 6" /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

SETUP/USE SPECIFIC JAVA FOR A SPECIFIC JAVA-BASED APP:in this way different Java-based App can use different Java . For this, we have to run a script file, & it will setup ENV VARs JAVA_HOME, PATH, etc only for that specific App, before running the app:cmd: sb='#!/bin/bash' ; echo "$sb" > /java-based-APP-name.sh ; unset sb;edit the shell script file:cmd: nano /java-based-APP-name.sh

EXTRA INFO:I was trying to run an old macOS app & the latest Jitsi.app.Jitsi showed message that it needed Legacy-Java 6, but after installing Legacy-Java 6, i received such error:[JavaAppLauncher Error] CallStaticVoidMethod() threw an exceptionException in thread "main" java.lang.UnsupportedClassVersionError: net/java/sip/communicator/launcher/SIPCommunicator : Unsupported major.minor version 51.0So i had to load Java 7 (1.7) for Jitsi (because, error-msg "51.0" points-to Java 7) . Jitsi can auto detect the needed Java version & use it, so no extra bash-script was needed for Jitsi, it ran fine.For the old macOS app, i had to use Legacy-Java ( Java 6 (1.6) ) & a bash-script (shown above).

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.

I'm having the same trouble as dartmadartist (trying to open illustrator yields "you need to install the legacy Java SE 6 runtime" popup... I recently reinstalled Yosemite 10.10.5 on my MacBook Pro which has caused this issue to come up...

They should be flexible about it - I dont have money to do the subscriptions so I stick with my CS6 since that doesnt require me to chuck money that I dont have...and it still works on my laptop no problems, minus the java issue...

When launching an Adobe app such as Photoshop, Illustrator, InDesign, or Premiere Pro on Mac, you may encounter the To open Adobe app you need to install the legacy Java SE 6 runtime error. Some of the older Adobe Apps require your Mac to have installed the Java SE 6 Runtime.

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. However, the error can be resolved by installing the legacy Java version.

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.

The best way to do this is go to logisim in your applications folder then double click to view show package contentes then you see a folder called "Contents" then click the folder "Resources" then "Java" then open the .jar extentiuon file . Yes ! you did open your logisim without any installation of java se 6 on your macos Catlalina. Thank you

On a macOS Catalina version 10.15.7 I'm trying to use the tabulizer package to extract a table from a .pdf and it is crashing RStudio and also crashing R (if I run it outside Rstudio). I get an error that says "To open 'RStudio' you need to install the legacy Java SE 6 runtime".

I tried to go to the java page and see if I could get an older version of Java (thought this seems sub-optimal) and it asked me where I want to put it saying it couldn't run both Java's on my machine.

The Shark software has a dependency on legacy Java 6 libraries for creating Word, Excel and PowerPoint presentations. Java 6 cannot currently be installed on Mac OS 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.

System extensions are a category of software that works in the background to extend the functionality of your Mac. Some apps install kernel extensions, which are a kind of system extension that works using older methods that aren't as secure or reliable as modern alternatives. Your Mac identifies these as legacy system extensions.

These messages look similar, but notice the first one refers to a specific application and the second one generally refers to the java command-line tool. In either case, there is software trying to launch at startup and at other times which is requiring Java.

Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion.

A number of users have struggled to get snappy working in recent macOS versions bybuilding jpy binary wheel. One common oddity was a failure running snappy-conf accompanied by a popup requesting installation of the legacy Java SE 6 runtime. This is a common issue for macOS users attempting to install applications that use the Java Native Interface (JNI). I recently obtained access to macOS Catalina and was able to reproduce this for SNAP 8 using:

The work around is to regenerate P12 keystore/truststore with keystore.pkcs12.legacy property as described in ( -java/issues/958),or to generated P12 key-store with java versions before 1.8u301 or java 11.0.12.

Re-generate truststore PKCS12 with "legacy algorithms" (which were default algorithm used when generating PKCS12 for java 8 until version 1.8.0u301 and java 11 until version 11.0.12). And then the upload of the truststore which will succeed.

The main website for ImageMagick can be found at The most recent version available is ImageMagick 7.1.0-61. The source code for this software can be accessed through the repository located at In addition, a legacy version of ImageMagick, version 6, is also still maintained and can be found at

To give your users easy access to your cloud apps, Azure Active Directory (Azure AD) supports a broad variety of authentication protocols including legacy authentication. However, legacy authentication doesn't support things like multifactor authentication (MFA). MFA is a common requirement to improve security posture in organizations.
