my phone will not reboot because of a earlier warning of exhausted space. the apple sign is perpetually on. i have a macbook and trying to use the usb c adapter to restore my phone but msacbook is not seeing the iphone 11 pro

Connect the iPhone to your Mac and open a new Finder window.

The device name will appear in the sidebar. Click it.

my phone kept saying it was full, i would delete things and it would magically be full again. i noticed over 7gig of other system files that had not been there before trying to make me upgrade my phone by making it unusable. today, my i plugged it to charge for the night, the phone lit up with the black screen of death and the apple logo in white. my mac does not recognize it as being plugged into it in the finder as suggested in this thread. i tried the force reboot by plugging it into itunes. but itunes was removed by apple and replaced with apple music. i can't install an older version of the app because my operating system is too new. i can't update to bigsur because my accounting software and full adobe suite of applications do not work on it, so I could not work either.

nothing is working with my phone, it will not turn off or boot. i need help, does anyone know of anything that can get it to boot?

This process below will get it started.

However if it is totally rammed full the chances of choosing “update” rather than “Restore” are slim and you may thereby wipe the phone.
