I've tried to update my macbook from 10.13.6 but unable to update to the current OS version. is there any way to update it?
Currently on macOS 10.13.6
You have tried. What happened exactly ? When did it fail ?
Have you checked you have enough memory available ?
May be you could try first to upgrade to Majave 10.15.7
