Guest ricoc90 Posted April 10, 2018 Share Posted April 10, 2018 Date and time settings are correct? I recall reading about this during the first betas and it was either solved by changing the date-time in some .plist file, or by updating the time through terminal: ntpdate -u "time.apple.com" After that remove the /macOS Install Data/ folder on your harddrive and try again Link to comment Share on other sites More sharing options...
autantpourmoi Posted April 10, 2018 Author Share Posted April 10, 2018 Hi Ricoc and thanks for your help . the time in my bios is correct . To be more precise, i'm trying to update from sierra 10.12.6 to high sierra 10.13.4 on my ssd BackUpSystem keeping my MacOS Sierra safe. So if i understand well, i should use the terminal on my safe sierra system to update the time , than delete the install folder on the ssd i was trying to update and restart the all process of install , right ?
