How to reinstall macOS Sierra to n my 2015 Intel-based MacBookPro (MBP) after running the First Aid multiple times

After erasing the original hard drive and tried to reinstall the macOS, it failed.

When powered up, it has the blinking folder pointing to the link: support.apple.com/mac/startup


After following the instruction from the link above, to run the First Aid on all the drive/volume items on the left for my 2015 Intel-based MBP, it still fail the original macOS Sierra again and again, after several attempts. Now I don't know what to do to reinstall the OS.


How can I get out of this loop or rebooting, repairing it with First Aid, and try to reinstall the macOS to the hard drive again?

Thanks.

Hi,

I suppose you are trying to install macOS on your MacBook Pro with Recovery Mode.

Try to reset NVRAM, then start up with Recovery mode could solve your issue.

Reset NVRAM on your Mac - Apple Support

Use macOS Recovery on an Intel-based Mac - Apple Support

If it doesn't help, you should take your MacBook Pro to your local retail AppleStore, Genius Bar or Apple Authorized Service Provider to install macOS on your MacBook Pro there.

As far as I know, it's free.

If you can run Sierra— you can run High Sierra 10.13.6 (17G14042) November 12, 2020

Why going back to Sierra on a 2015... you do not paint a very big picture...

What to do before you sell, give away, or trade in your Mac



A 2015 is quite capable of running macOS Monterey—macOS 12.6.2

Thanks much leroydouglas for your helps too. It is good to know I have the option of a newer macOS, will try that. My kid bought the latest MBP and gave me this 2015 he bought. It is still new and good enough for me, a PC user mainly. I may use it to get to know Mac more and use it for testing app to see how they run on Mac platforms.
