To install the JDK on macOS: Download the JDK.dmg file, jdk-10.interim.update.patch-macosx-x64.dmg. Before the file can be downloaded, you must accept the license agreement. From either the browser Downloads window or from the file browser, double-click the.dmg file to start it. Aug 31, 2019  If I click 'Open Anyway', it opens the 'jdk-12.0.1.jdk' folder in finder, but does not change the result above. Tags: none ( add ) This content has been marked as final.

Jul 01, 2017  Even Picture Viewer does not open. Problems started with Outlook that did not open because of access denied to.pst - tried to rectify by granting permission to my user directory and then next thing the start button stopped working - can right click, but a normal click does not bring up the menu. Other apps like Edge opens but closes immediately.

I would like to use the WatchService API as mentioned in this link:
http://download.oracle.com/javase/tutorial/essential/io/notification.html

After reading around, I found out that WatchService is part of the NIO class which is scheduled for JDK 7. So, it is in beta form. It’s fine.

http://jdk7.java.net/download.html has the JDK which I downloaded and extracted. I got a bunch of folders. I don’t know what to do with them.

Then, I read around some more and found that some nice group of people created JDK 7 as a binary so someone like me can install it easily. It is called Open JDK:
http://code.google.com/p/openjdk-osx-build/

So, I downloaded the .dmg file and install it. Then I open “Java Preference” and see that OpenJDK7 is available.

So, now I feel that I can start trying out WatchService API. From the tutorial in the first link, the author gave a .java file to test it out first and make sure that it is running. Here is the link to the file:
http://download.oracle.com/javase/tutorial/essential/io/examples/WatchDir.java

So, I boot up Eclipse (actually I use STS) and create a new Java project and choose JaveSE-1.7 in the “use an execution environment JRE:”. Under the src folder, I copy pasted the WatchDir.java file.

And I still see tons of squiggly red lines. All the “import.java.nio.*” are all red and I cannot run it as a Java app.

What do I need to do?

EDIT: I actually did not pursue using Java 7 but there are a lot of interest in it and it seems like people keep answering this question. What should I do to make it more relevant to people who search for it? Let me know by PMing me.

This is how I got 1.7 to work with Eclipse. I hope it helps.

1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK
   from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to the
   default 1.6.0 one
3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and
   name Java SE 7 (OpenJDK)
4. Click Finish
5. Set the added JRE as default

that should be it 🙂

You can download the Java Development Kit (JDK) for Java 8 for the supported versions of Mac OS X:

• Mountain Lion (10.8.3+)
• Mavericks (10.9)
• Yosemite (10.10)
• El Capitan (10.11)

Each version of JVM you install can be found here:

For more instructions and FAQ, see this Oracle Guide.

For every release of Java 7 since Update 4, a Mac version has been ready alongside the other platforms. Runs on Macs with 64-bit hardware on Lion (10.7.3+), Mountain Lion (10.8.3+), and Mavericks (10.9.x).

Oracle announced the official release of the JDK for Java SE 7 Update 4 on Mac OS X (Lion), as of 2012-04-26. No more need for the tricks discussed on this page.

Installation is simple per these instructions:

1. Download from the usual place on the Oracle web site.
2. Mount the DMG.
3. Run the installer.

This release has a few limitations, most notably the lack of support for Java Web Start and the Java Plugin for web browsers. That support is expected later this year.

After installing, read the JDK for Mac ReadMe. Most importantly, if you want Java 7 to be the default, drag it to the top of the list in the Java Preferences app found in your Utilities folder.

Mac OS X easily supports multiple JVMs simultaneously. Each is now found here:

Congratulations to the Apple & Oracle teams for their achievement. This geek gets a thrill seeing Mac OS X listed as a “Certified System Configuration“.

Tip: To start Eclipse on a Mac with only Java 7 installed, open the alias file named eclipse rather than the file named Eclipse.app.

Apple continues to supply an up-to-date implementation of Java 6 for all versions of Mac OS X up through Mountain Lion.

If you do something that requires Java, such as type “java -version” in Terminal.app, a dialog appears offering to install Java for you. If you accept, installation happens automatically similar to other “Software Updates” from Apple.

You will find Java installed in this location, different than Java 7 & 8:

Java 6 has reached end-of-life with Oracle as of 2013-02 (unless you have a commercial support agreement with Oracle). So you should be moving to Java 7 or 8.

In Terminal.app, type java -version to verify which version is the current default.

An easy way to install Java 7 on a Mac is by using Homebrew, thanks to the Homebrew Cask plugin (which is now installed by default).

Run this command to install Java 7:

I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).

Install Java Jdk Mac

What I did to get this working on my machine is to:

• followed instructions on Oracle JDK7 Mac OS X Port for general installation
• in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
• select Platform Settings > SDKs, press “+” (plus) sign to add new SDK
• select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from “lib” directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
• you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)

It’s possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn’t mean Eclipse knows where to find it.

Go to
Preferences > Java > Installed JREs

If there is not an entry for the 1.7 JDK, add it. You’ll have to point Eclipse to where you installed your 1.7 JDK.

If Eclipse can’t find a JRE that is 1.7 compatible, I’m guessing that it just uses your default JRE, and that’s probably still pointing at Java 1.6, which would be causing your red squiggly lines.

after installing the 1.7jdk from oracle, i changed my bash scripts to add:

and then running java -version showed the right version.

Get cask

Install java7:

(I had difficulty finding the download link of java7 on oracle website, as they’re just “recommending” java8 )

How about Netbeans, here is an article how to set it up with NB7:

Maybe similar steps for Eclipse.

As of April 27th there is an offical Oracle release of Java SE 7u4. Download the disk image and run the installer – then see the Mac readme.

The instructions by peter_budo worked perfectly. I had to add the jars under /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib/ to my IntelliJ project libraries. Now it works like a charm. Note that I didn’t need my IDE itself to run under 1.7; rather, I only needed to be able to compile and run against 1.7. I’ll most likely continue to use Apple’s JRE for running the IDE since it’s probably more stable with respect to graphics routines (Swing, AWT). Like the OP, I was really keen on testing out the new NIO2 API. Looking good so far. Thanks, Peter.

What worked for me on Lion was installing the JDK7_u17 from Oracle, then editing ~/.bash_profile to include:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_13.jdk/Contents/Home

I updated to Yosemite and Android Studio wouldn’t clean my projects or Run them on virtual or real device because of the following error:

After some research and trouble shooting, I found that the JDK file that was being pointed to at “/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home” wasn’t there; all of “JavaVirtualMachines/1.6.0.jdk/Contents/Home” was missing from “/System/Library/Java”. So, I copied “JavaVirtualMachines/1.6.0.jdk/Contents/Home” over from “/Library/Java/” to “/System/Library/Java/” and cha ching! I was back in business.

It is very common to download and install apps from internet on Windows PC or laptop. However, it’s not a good idea on Mac to install third-party apps to protect your computer. Though the best way is to install apps from Mac App Store it has few problems. First, many people confuse iOS App Store with Mac App Store – they are two different stores. Second, there are only few apps available in Mac App Store that will not cater your requirements. This makes you to look for apps from third-party websites. However, you need to make some settings in order for the third-party apps to work on your Mac.

How Mac Checks Third-party Apps?

Generally, you can download .dmg or .pkg or plugin files and install on your Mac. Apple checks the following when you install app from the third-party websites:

• Check it is a trusted software using Gatekeeper technology.
• Verify the identity of the developer using Developer ID in the installer package.
• macOS Catalina also needs the developer to notarize the apps for trustworthy.

Most of the third-party apps will fail at the identification or notarization part leading to prevention of usage on Mac. In most case, you may be using it for long time, and it is not quite easy to inform the developer to update the app.

Third-party Apps Errors in Mac

Mac settings allow you to choose only install apps from App Store or allow apps from identified developers. You will get different error depending upon this setting. When you allow third-party apps in settings, Mac will not stop installing or updating the apps without developer ID and notarization. It will only stop when you open the installed app. This will make an app unusable with an update in the latest macOS. You will get the error like below mentioning, “App can’t be opened because Apple cannot check it for malicious software”.

You will see an error, “App can’t be opened because it was not downloaded from App Store” when you have setting that does not allow apps outside App Store.

In all cases, the error message will show how did you download the app with no option to open.

How to Open the Blocked Apps?

Now that you have multiple options to open the app.

1. Allow Apps from Outside App Store

If you have blocked the third-party apps then ensure you allow in in the settings.

Jdk Mac Download

• Click on the “Apple” menu and choose “System Preferences…” option.
• Look for “Security & Privacy” option and click on it.

• If the screen is locked for edit, click on the padlock icon and unlock the screen by using your admin login. You will see two options under “Allow apps downloaded from:” – “App Store” and “App Store and identified developers”.
• In order to allow the third-party apps, select the option “App Store and identified developers”.

Henceforth, Mac will show an open button when you try to access an app downloaded from internet.

2. Use Open Anyway After Blocking

In macOS Catalina and Mojave, you will see the last attempt of blocking the app with an option to “Open Anyway” button. Click on the “Open Anyway” button to access the app.

Now you can open the app and confirm the access by clicking on “Open” button.

3. Open the App with Right-Click

You can also access the app without going to settings. When you get the error message, click on the “Show in Finder” button. Alternatively, open “Finder” and go to “Applications” folder to locate the app. Control click or right click on the application file and choose “Open” option.

You will get the same error message for malicious software checking like below. However, this time you will see an additional “Open” button.

Click on the “Open” button to access the app.

Caution

Mac App Trying To Launch Jdk Update

When Mac is certain about the malicious software, it will show “App will damage your computer. You should move it to the Trash”. In this case, ensure to move the app to trash and clean up the Trash instead of trying to open. Only open the apps that you are sure and using it previously. It is also good idea to report the issue to the developer to update the app for the latest macOS Catalina version.
