macOs mojave installation failed
At first, the macOS mojave would not download on my macbook air OS X El capitan, version 10.11.6. after some weeks of trying repeatedly, it downloaded, but each time i click continue when trying to install, it gives this error message: "Downloading installer information to the target volume failed". I have tried repeatedly with same result.
Why is this happening? and what can i do to fix it? i need to update my iTunes in order to connect it with my phone.
pls HELP! thanks.
