Please do the following before installation:

• Click on the 'Apple' button (top left), go to:
  
  
• System Preferences > Security & Privacy > General Tab
  
  
• In case the option is there then toggle on Allow apps to be installed from App Store and identified developers, this may ask for admin credentials.
  
  
• Keep this window open when starting to install OpendTect. When you start the installer for the first time you might get the error message: "OpendTect Installer" can't be opened because the identity of the developer cannot be confirmed. or the error message "OpendTect Installer" can't be opened because Apple cannot check it for malicious software.
  
  At System Preferences > Security & Privacy > General Tab there should be a message like "OpendTect Installer" was blocked from opening because the identity of the developer" cannot be confirmed. or "OpendTect Installer" was blocked from use because it is not from an identified developer. Click the lock icon to make changes and then click the Open Anyway button.

• Once the installation is finished, and assuming you made a change to the security setting then you may change the security back.

Please note that in order to install OpendTect into the Applications folder the user that installs OpendTect should be allowed to administer this computer. You can check whether this option is toggled on via Users & Groups.

Now click Proceed.

8. The OpendTect Installation Manager identifies the platform on which it is running. This information is then anonymized prior to it being sent to OpendTect. We use this anonymous data solely for the purpose of getting a picture of OpendTect usage and thus improving our support capabilities.|
   
   
9. The next window of the wizard is the OpendTect Package Manager. Multiple items can be toggled on or off by checking the boxes. Optionally, the relevant package combination could also be selected from the top list box.
