My computer will not boot. I believe the disk is full. I want to enter safe mode and remove items but the shift key will not enter me into safe mode.
iMac, iOS 10.1.1
If your internal hard drive is that full, you will need to do as Kappy suggested. If you mean the disks that came with the computer, you can use those or you can erase and reinstall from the Recovery Partition. Using the Recovery Partition will reinstall the current OS.
Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair Disk and Repair Permissions until you get no errors. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Quit Disk Utility, then re-install the OS. Use Setup Assistant to selectively restore your data.
If the disk is full then you can only use Disk Utility to erase the drive and install macOS. You cannot delete files, copy files, trash files, or backup files.
I need to erase the drive and reinstall the iOS? Can I use the disks?
My Mac will not boot. When I go into disk utility it shows as full. I want to enter safe mode but the shift command on boot does not work.
