When I booted my Mac last night I got a flashing folder against a gray background. The computer started fine this morning, but when I closed the lid and opened it up again I had to reboot, and now it's persistently in this flashing folder state.
Booting while holding down ⌘ Cmd–R brings me to OS X Utilities. Running "Repair disk" from disk utilities indicates there's no problem, but I did notice that it also says I only have 16 MB free on a 110GB hard drive.
Might this be the problem? If so, is there some way to delete data from my computer while in this state, to clear enough space to boot correctly?

Though the following should be valid for non-encrypted volumes and unlocked encrypted volumes, it doesn't help much because the main volume here is encrypted and locked. So skip to FileVault2-encrypted volumes
Non-encrypted volumes
Almost no free space on your start volume is a problem. At least 10 % free space are recommended.
It's indeed possible to remove files & folder in Recovery Mode but if you have an external disk/thumb drive (hfs+ or fat32-formatted) you may move them instead:
cd /Volumes/NameOfYourMainVolume/Users/accountname
to change to your user folder (example:cd "/Volumes/Macintosh HD/Users/ausername"
). To get the names/mountpoints of your main volume/external disk enterdiskutil list
ordf
.enter
ls -la
to show all files and foldersExample:
cd SomeFolder
enter
ls -la
to show all files and foldersExample:
to move BigFile.mov to your external device enter
mv BigFile.mov /Volumes/ExternalDevice/
or to move UnwantedFolder to your external device enter
mv UnwantedFolder /Volumes/ExternalDevice/
.if you don't have an external drive remove folders and files with
rm -dr UnwantedFolder
to remove UnwantedFolder and all its content orrm BigFile.mov
to remove BigFile.mov (4.7 GB in the example above).rm *.mov
removes all .mov files in your working directory.rm is a powerful command to delete a file or directory without confirmation by default. Because of this behavior, users should really be sure before deleting files or folders. So double check where you are - enter pwd to print your working directory - and what you want to delete!
FileVault2-encrypted volumes
started to Recovery Mode open Disk Utility
If you had one partition spanning your whole hard drive and encrypted it with FileVault2 it's completely normal that you have only some MB available space left. That's unallocated free space on your hard drive. In the example above 12,7 MB are left.
highlight your FileVault2 volume and unlock it.
enter the FileVault password
if you succeed and the encrypted volume isn't corrupted your FileVault2 volume will be mounted. Check the available free space. In the example below the availbale free space on the volume is 52,8 GB
If the unlocking fails - using the correct password - the FileVault2 volume probably is corrupted. The only possible solution then is completely erase/repartition the hard drive and restore a backup.
