when it's powering up, it's has spinning cursor and progress bar. When progress bar is about 1/2 way system just shut down.
I tried safe startup (with shift key) and it's same thing and shut down.
the last time i was using it, was 3 weeks ago when it was updated bluetooth software and system was restarted just fine. that was it.
anyone can help me?
Hello Charles,
We know it's important for your Mac to startup as expected. There is a great article that we have linked below that provides some great troubleshooting steps in addition to attempting to boot the Mac in to safe mode. If you continue to have issues after those steps we can recommend resetting the NVRAM. The steps for resetting the NVRAM can be found in the second article linked below.
Have a great day.
Nicholas_B2,
I have successfully startup my mb using steps in "Reset NVRAM..." to use Disk Utility to repair my mac.
THANKS!
Nicholas_B2,
Thank you for the helpful tips.
I tried all the steps.
my MB turned on but it shuts down after waiting cursor spinning.
I think i have to contact support.
Hello Charles,
We're glad resetting the NVRAM, and repairing the disk through Disk Utility resolved the issue. If you need any assistance in the future let us know.
Take care!
