So I've been downloading the 10.14 update and surprisingly, I cannot update due to S.M.A.R.T issue on my SSD. I am aware of this since 2016 and the driver is still doing fine, I don't use my PC that much as it's a test Mac. Now how come the installation won't let me pick the drive? on Windows I just finished installing update 1809 for Windows 10. Is it normal that Apple won't let me decide if I want to take the risk and install the upgrade? I won't pay $500 for an SSD replacement on a 2012 Mac. Is there anyway to bypass this restriction other than using an external disk and clone everything back?
