DashBoardClient - Stop it to install Adobe Flash on Mac

Apple/Adobe Users:

This solution worked for me with the latest version of Adobe Flash and MacOS 10.5.7 (latest software updates installed). However, I am going to clarify a bit more what I did.

Step 1 - Open Terminal (You can find it under /Applications/Utilities/)

Step 2 - To turn Dashboard off:

Type this into Terminal and press enter:

defaults write com.apple.dashboard mcx-disabled -boolean YES

Step 3 - find the Dock process id:

Type this into Terminal and press enter:

ps -ef | grep 'Dock' | grep -v 'ashboard' | grep -v 'grep'

The SECOND number from the left is the process id for the Dock.

Step 4 - Kill the Dock:

Type this into terminal and press enter (replacing '<processid>' with the number you found above, second from the left):

kill -9 <processid>

Step 5 - Install Flash Player per Adobe's installer

Step 6 - To turn Dashboard on:

Type this into Terminal and press enter:

defaults write com.apple.dashboard mcx-disabled -boolean NO

Step 7 - find the Dock process id:

Type this into Terminal and press enter:

ps -ef | grep 'Dock' | grep -v 'ashboard' | grep -v 'grep'

The SECOND number from the left is the process id for the Dock.

Step 8 - Kill the Dock:

Type this into terminal and press enter (replacing '<processid>' with the number you found above, second from the left):

kill -9 <processid>

Step 9 - Press "F12" or whatever function key brings up Dashboard to assure it is functioning again now.
