ADmtiMac v5 is not supported on OS X 10.7, Lion. If you have already upgraded to Lion, the incompatibility can cause a situation preventing you from logging in to any account. To remedy this situation, please follow these steps:

NOTE: If you do not feel comfortable performing these steps, please contact our Support Specialists for further help.

1. Restart the computer holding down the Command+S keys. This will start the system up in Single User mode.

2. At the prompt type the following commands (these commands will be listed above the prompt just in case you need to reference them):

   /sbin/fsck -fy    {hit the return key}

   /sbin/mount -uw /    {hit the return key}

3. Modify the /etc/authorization. At the prompt type

   vi /etc/authorization    {return}

This opens the file in the vi editor.  Then type:

   /AMHomeDirMechanism    {return}

This searches for the first occurrence of AMHomeDirMechanism (case-sensitivity is important).

do this:

dd     (don't press return, this deletes the line the cursor is on)

n     (don't press return, this searches for the next occurrence of AMHomeDirMechanism)

until there are no more occurrences of AMHomeDirMechanism (vi will say "E486: Pattern not found: AMHomeDirMechanism"). Depending on the version, there will be 3 or 4 occurrences.

Then:

   :wq    {return} (This saves the file).

(NOTE:  You may see "E138 Can't write ciminfo file $HOME/.viminfo!".  If so, please hit the return key, then continue.)

   exit    {return}

This last line allows the boot to continue, and you should then be able to log in and INSTALL ADmitMac v6.
