The first step would be to stop using the system to not further damage the software and hardware components.Īnd once you have isolated the system, the next step would be to look for a resolution that can help you get back your trapped data inside a MacBook not turning on. Instead of panicking and making mistakes, you must take the right steps after encountering such a problem. The real worry is not that you cannot boot up the Mac what worries you most is the sensitive data you have in your system that is being trapped due to boot-up error. You may fix it with Disk Utility and with some luck.
