  • Note: As of Flutter’s 1.19.0 dev release, the Flutter SDK contains the dart command alongside the flutter command so that you can more easily run Dart command-line programs. Downloading the Flutter SDK also downloads the compatible version of Dart, but if you’ve downloaded the Dart SDK separately, make sure that the Flutter version of dart is first in your path, as the two versions might.
  • To get the list of all files with Extended Attributes: find. To remove the Extended Attributes from a file: xattr -c filename.txt. If I was a real.NIX wizard, I'd find a way of piping the output of the first command into the parameters of the second one.

There are various tricky issues with having multiple versions of Java (Apple's own Java 6 and Oracle JDK 7 or even 8) on one's Mac OS X system, and using different versions for different applications. I spent some time writing up my experience of my experience of installing and configuring various versions of JDK on Mac OS X 10.9.2. Idk i do not use mac os soo. ME BOBUX MAN/KING 21 days ago (+1) me too and ik how fix it. I need to go in settings and click download file of unvefiried developers and apple store developers or something of this.

This page describes how to install and uninstall JDK 8 for OS X computers.

This page has these topics:

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

See 'OS X Platform Install FAQ' for general information about installing JDK 8 on OS X.

System Requirements

Observe the following requirements:

  • Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

  • Administrator privileges.

Note that installing the JDK on OS X 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 as described in 'Uninstalling the JRE'.

JDK Installation Instructions

When you install 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-8uversion-macosx-amd64.dmg

  • jdk-8uversion-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.

    A Finder window appears containing an icon of an open box and the name of the .pkg file.

  3. Double click the package icon to launch the Install app.

    The Install app displays the Introduction window.


    Note:

    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.

  4. Click Continue.

    The Installation Type window appears.

  5. Click Install.

    A window appears that says 'Installer is trying to install new software. Type your password to allow this.'

  6. Enter the Administrator login and password and click Install Software.

    The software is installed and a confirmation window appears.

  7. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

  8. After the software is installed, delete the .dmg file if you want to save disk space.

Determining the Default Version of the JDK

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 app. See 'Note for Users of OS X 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 8u6, you will see a string that includes the text 1.8.0_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.

For example, to uninstall 8u6:

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.

macOS users often experience a self-assigned IP address issue that allows the network interface to create an ad-hoc connection, if necessary. This means, even though you have working Wi-Fi, the internet not working messages will keep popping up.

Your system will create an ad-hoc network only if they find the hardware but have issues communicating with the DCHP server to obtain your IP address. The issue lies within the system’s Firewall configuration problems, and there are many ways to resolve it.

Let me show you a step-by-step guide on how to fix the self-assigned IP address issue on Mac.

Method 1: Reset your network preferences on Mac

  1. Launch Finder.
  2. In the menu bar, click Go →Go to Folder.
  3. In the pop-up window enter the mentioned line: /Library/Preferences/SystemConfiguration/
  4. Delete these files: (add 04)
    com.apple.airport.preferences.plist
    Networkinterface.plist
    preferences.plist
  5. Restart your Mac.
  6. Log in and connect to your Wi-Fi network.
  7. Go to the TCP/IP setting again and check the router files.

After your Mac restarts, you should be able to find the deleted files in your folder.

Method 2: Renew DHCP Lease on macOS

  1. Click on the Apple logo.
  2. Go to “System Preferences.”
  3. Find and go to “Network” settings.
  4. Select Wi-Fi or Ethernet. Mostly, these options are selected by default.
  5. Click the “Advanced” button. (add ss9)
  6. Go to the TCP/IP tab.
  7. Find and click the “Renew DHCP Lease” button next to IPv4 Address line.
  8. Click “OK.”

After the lease is renewed, check if you’re able to connect to your network. If that does not help, we will try creating a New Network Location and renew the lease.

Method 3: Create a new network location

.bash_profile
  1. Click the Apple logo.
  2. Go to “System Preferences.”
  3. Find and go to “Network” settings.
  4. Next to “Location,” click the drop-down menu.
  5. Click “Edit Locations.”
  6. Click the + icon to add New Location.
  7. Name the New Network Location.
  8. Click Done.
  9. Select Wi-Fi or Ethernet. Mostly, these options are selected by default.
  10. Click the “Advanced” button.
  11. Go to the TCP/IP tab.
  12. Find and click the “Renew DHCP Lease” button next to IPv4 Address line.
  13. Click OK.

Try connecting to your network after renewing the lease.

When you try to perform configuration changes to the system, your Mac’s Firewall experiences configuration issues. Let’s fix this problem by resetting the Firewall.

Method 4: Reset the Firewall on your Mac

  1. Launch Finder.
  2. In the menu bar, click Go →Go to Folder.
  3. In the pop-up window, enter in: /Macintosh HD/Library/Preferences/
  4. Delete the following file: com.apple.alf.plist
  5. Restart your Mac.

After your system boots, it will ask you to allow access to numerous programs and services. You may choose to allow access to numerous programs and services depending upon your choice. Try connecting to your network then.

Method 5: Set Service Order from Mac’s network settings

  1. Click the Apple logo.
  2. Go to System Preferences.
  3. Find and go to Network settings.
  4. Click the gear icon at the bottom.
  5. Click Set Service Order.
  6. Drag services to the top of the list

If you’re using Wi-Fi, drag and drop Wi-Fi to the top.

Method 6: Change DNS servers on macOS

  1. Click the Apple logo.
  2. Go to System Preferences.
  3. Find and go to Network settings.
  4. Select your Wi-Fi or Ethernet. Usually, they are selected by default.
  5. Click the Advanced button.
  6. Go to the DNS tab.
  7. Click the + icon.
  8. Add these numbers:
    8.8.8.8
    8.8.4.4
    1.1.1.1
    9.9.9.9
  9. Click “OK.”
