Monterey won't install
2015 MacBook Pro won't install Monterey, it downloads ok and the install starts but after 17 minutes I get the message " there is a problem please try again" but I just get the same response.
I have installed a larger hard drive a few years ago and don't have the old one which had problems anyway so is there any way left to upgrade my Mac?
MacBook Pro 13″, macOS 11.6
