Installation of PDTOOL v1.2 App on Mac computers

IMPORTANT: Mac OS X Sierra (10.12 and later) require special procedures to install PDTOOL. These are given below.

Mac OS X 10.11 (El Capitan) and earlier

1. Download MacAppInstaller.zip


2. Save the file into a convenient directory, and unzip the file.


3. Navigate to the folder in Finder, and double-click on the MacAppInstaller_web icon, and follow the installation procedure. You made need to change your Security Preferences temporarily to allow the install. Please note that the installer downloads the required MATLAB libraries from the MATLAB website (~300 Mb), so the download takes a while. Depends on your connection speed, of course, but 10-15 minutes is possible.


4. After the app is installed, navigate to it and start the program. For example, the app may reside in Applications -> PDTOOL -> application. The app is called "PDTOOL."

Mac OS X 10.12 (Sierra)

Starting with release 10.12, Apple has added an extra layer of security to prevent the installation of malicious apps. When an app is dowloaded from the web, it is tagged with a "quarantine" attribute that must be removed before this software can be installed. The procedure below, which must be followed exactly, will remove the quarantine attribute, and allow installation of the software.

1. Download MacAppInstaller.zip


2. Save the file into a convenient directory, and unzip the file.


3. Navigate to the folder in Finder, and then to the sub-folder where you will find MacAppInstaller_web. DO NOT try to open or run the installer from this directory. If you do, the app will be quarantined, and you will have to delete everything and start over. Drag the app to the Applications folder, found in the column of Favorites on the left.


4. Open a Terminal window, found in the Applications -> Utilities folder. At the prompt enter the following commands (in red):
   
   
   • cd /Applications This takes you to the Applications folder
   
   
   • xattr MyAppInstaller_web.app This determines what attributes have been set on the app. The command should return "com.apple.quarantine", indicating that the quarantine attribute is set.
   
   
   • sudo xattr -r -d com.apple.quarantine MyAppInstaller_web.app This is the command to remove the quarantine. The sudo part runs the command as Administrator. You will be prompted for your password before the command is allowed to execute. (You must have Administrator privileges for sudo.)
   
   
   • xattr MyAppInstaller_web.app This time the command should return nothing, indicating that the quarantine attribute has been unset. You can now proceed with the installation.

Please note that the installer downloads the required MATLAB libraries from the MATLAB website (~300 Mb), so the download takes a while.
