I was trying to install Catalina on Macbook pro 2019. As the result of this attempt my Macintosh HD became unmounted. Apple Support did not help. I restored computer from Time Machine and tryed again to install Catalina. Failed again. Now I saw the message "Mac OS could not be installed on your computer. Some information was unavailable during an internal lookup.: (-69808)"
I was trying to do it again – the same result.
Can Catalina be installed on MacBook Pro 2019???
