Do you have a tendency to click the firmware update button when Apple pushes new firmware versions? If so, then MuscleNerd tweeted that you can apply a simple command to Mac OS X computers that will stop you from being able to perform a firmware update through iTunes. This simple command is applied through the terminal.app and can also be un-done easily with a simple reverse command…
If you are interested in applying this firmware update protection follow the steps below…
Step 1) – Launch the terminal app from your computer (Mac OS X only)
Step 2) – Once terminal is up and running enter the following command and press enter
defaults write com.apple.iTunes personalized-installation-server-host /dev/null
Step 3) – Once you have entered the above command into terminal you will not longer have to worry about accidentally updating your iDevice.
Re-Enabling Firmware Updates: Now when you want to update your iDevice’s firmware you are going to need to simply type in the following command into the terminal.app.
defaults delete com.apple.iTunes personalized-installation-server-hostl
