upgrade macos 10.14.6 version to 10.15.0
i cant upgrade my mac software. it keeps saying that macos cannot be installed on macintosh HD. What do i need to do?
MacBook Air 13″, macOS 10.14
The 2018 should have no difficulty upgrading unless it only has 128 GB of storage. Go to Apple menu -> About This Mac -> Storage to find out just how much storage it has, and how much is free.
