Release Notes: WICED Studio 6.6.0

OSX Install:

  • Download the attached .zip file
  • Double click the zip file and extract all contents from the installer to a local folder
    • Note: When using the Safari Browser, it will automatically unzip the contents and create a folder
  • Note: the next two steps below are needed as a workaround for a known OSX 10.12 install issue called "App Translocation"
    1. Move the contents of the folder to another folder using ‘Finder’; Do not move the files using ‘Terminal’
      • Be sure to move the entire folder contents including the installer app file and config.eml.
    2. Run the command below using Terminal window:
      > xattr -r -d <path>/
  • See "Additional Installation Notes" below before installing
  • Double click the "WICED-Studio-X.X.X.X-IDE-Installer" app to execute the installer
  • After the installation in complete, launch the WICED Studio IDE from shortcut in the $HOME/Cypress $HOME/WICED/WICED-Studio-X folder

OSX Uninstall:

  • From Finder, navigate to User > <name> -> Applications  -> Cypress and launch 'Uninstall'
  • To clean up all WICED components manually, delete files and folders for the IDE and SDK, typically in User -> <name> -> WICED/WICED-Studio-X and User -> <name> -> Documents -> WICED/WICED-Studio-X  or from terminal $HOME/Cypress/WICED*, $HOME/WICED/WICED-Studio-X and $HOME/Documents/WICED/WICED-Studio-X

Additional Installation Notes:


Open xterm, run the "java -version" command.  If it fails to return any results or states that you are running version 1.6, then you need to install the Java SE Development Kit 8, which can be found here: Once the Java SE Development Kit 8 is installed, run the "java -version" command again with xterm.  If this command returns "1.6", then you will need to fix the symbolic link using the following commands:

> rm -f /usr/bin/java

> ln -s /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java /usr/bin/java


Application downloads on WICED platforms may fail on certain OSX versions due to an incompatibility between the OSX version and the installed driver for the FTDI USB to serial chip.  On OSX versions 10.10 and earlier, a specific version of the FTDI driver must be installed using the instructions available here:

On OS X versions 10.11 and greater, the Apple version of the FTDI driver must be used, and any previous instance of the FTDI version of the driver must be removed from the system, by executing the following command in xterm:

> sudo rm -rf /Library/Extensions/FTDIUSBSerialDriver.kext /System/Library/Extensions/FTDIUSBSerialDriver.kext

Reboot the system after performing the rm command

(macOS Big Sur) Removed Java 11,9,7

ls /Library/Java/JavaVirtualMachines/

$ /usr/libexec/java_home -V


$ rm -rf /Library/Java/JavaVirtualMachines/jdkX.X.X_NNN.jdk

install Java 8 (for macOS x64 Installer).

Oracle JDK8 

WICED installation as described above but:

xattr -r -d <path>/


$ chmod +x*

Istallation OK!

Starting WICED IDE: "Alert: Failed to create the Java Virtual Machine."

JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/lib/libserver.dylib

JavaVM FATAL: Failed to load the jvm library.


$ find /Library/Java/ -iname libjvm.dylib


To satisfy eclipse IDE:

$ sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/lib/libserver.dylib /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/jre/lib/server/libjvm.dylib


$ ls -la /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/lib/libserver.dylib

/Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/lib/libserver.dylib -> /Library/Java/JavaVirtualMachines/jdk1.8.0_281.jdk/Contents/Home/jre/lib/server/libjvm.dylib

$ cd ~

$ open WICED-Studio-6.6/

After this works! To compare with the installation on W10 is hard to find issues like this.
