My 2013 Retina MacBook Pro won’t load past the Apple logo with the spinning wheel. It has a 1 TB SSD that I filled up entirely. I tried to delete enough data to have a successful restart, but it won’t budge with over 10 GB freed.
It has no hardware damage, no liquid damage, or any other software issues. How can I get it up and running again?
Your Mac’s problem is insufficient storage space. If you have a backup of your Mac, I highly recommend you erase the internal hard drive and reinstall macOS from scratch.
If you have another Mac, you can also access the files on your unbootable Mac through Target Disk Mode, but it’s more complex, as you’ll also need a Thunderbolt cable to connect them.
