This morning I needed to reset an administrator's account password on my Mac, because I had forgotten the password.
I used the steps listed on this article to accomplish this, but after restarting the Mac, I found that it was taking a while to boot. I shrugged this off, let it sit for while, then came back around half an hour later and it was still booting. I tried to restart it again, but to no avail.
- the computer is an iMac 2009
- running OS X 10.7.5 Lion
- no Recovery partition or capabilities
- When I run the
fsck -fycommand in single-user mode, the computer returns:
Root file system
Executing fsck_hfs (version diskdev_cmds-540.1~34).
Checking Journaled HFS Plus volume.
Invalid B-tree node size
The volume could not be verified completely.
/dev/rdisk0s2 (hfs) EXITED WITH SIGNAL 8
