Easter Egg problem: Apparently Steve Jobs presented his first Apple machine to the world on 24 April 1984, calling it an ‘Easter Egg’. For reasons I’ve not discovered the greyed out file problem can sometimes be fixed by changing the file date to one prior to said 1984 date.
Renaming a copy didn’t work. The “unlock procedure” went like this:
- Navigate your way to your Downloads folder.
- Find the file that is greyed out.
- Make a copy with a new name. Example: chess.dmg when copied would be chess_new.dmg
- Delete the original file.
- Wait at least five minutes.
- Change the name of the copy back to the name of the original file. Example: chess_new.dmg becomes chess.dmg
- Now try the installation method again.
- When you look at the Setting > Language section and (was it?) Input, is the Keyman file grey or black?
- If it is black you should be able to install the Ngbaka keyboard.
- If it is still grey repeat steps 1-5 but this time wait ten minutes.
This method failed. Then we tried this but it will not let the translation consultant key her password:
Find the troublesome Keyman file in Finder.
Open the Terminal.
Type the following command, followed by a single space (do not press Enter yet).
sudo chflags nouchg
Drag the Keyman file from the Finder to the Terminal window. This will add the full path to the folder for the file.
Press Enter to run the command, supplying your password when prompted.
So we are stuck. As a Windows user it is tricky trying to help a Mac user with this. Is the security chip in the latest macOS kit objecting to a digital signature? (Now grasping at straws.)
