    Macbook A1465 works fine Linux but turns off in MacOS

    Hello

    I have this macbook Air 11 inch, was working fine with macos,,, then suddenly turns off by itself after apple logo screen.....it cant boot...
    Formating and installing does not work because it also turns off.....

    But: booting linux ubuntu from pendrive and also installing it in ssd works fine!! hours and hours, the macbook runs fine and fast and cool....

    So she does not like MacOS , loves Linux... can this be related to EFI? I have tried booting macos with shift pressed and allow me to login but even in this safe mode it turns off itself with a dialog saying "Are you sure you want to shut down your computer now" but I did not press power off.... now it is worse it does not ask such dialog and turns off...
    Temperature is normal because linux works fine.... no water damage...

    weird very weird issue. any hint?

    Rule out hardware issues by either running ASD or D from boot. Ubuntu usually runs fine on device with hardware issues in my experience, it's quite forgiving as it just ignores any errors. Apple kexts may result in a panic when defective hardware is initialised.

          ah ok it is the volt at VP0R which is arround 6.8Vol but there is nothing in schematics nor boardview with that name vp0r.... i will test deeply again with the advance test AND CONNECTED TO CHARGER, because stupidly was on battery testing....

                    Re: Macbook A1465 works fine Linux but turns off in MacOS

                    finally it is a keyboard problem, because disconnected keyboard/touch and used external keyboard and no problem at all....
                    i do not know why ubuntu was working and not turning off anyways....

                    The power key is ok, so again no idea of why it is turning off except that a bad keyboard combination produces the shutdown


                    thanks a lot
