Sad Mac Error (0000000F / 00000001) User Explanation
Summary
An Exception has occurred while starting System file execution. The error most likely indicates a software problem (except as noted below).
Details
An "Exception" is a Programmer term for a serious (and unexpected) problem happening during the normal activity of the computer. The system has most likely failed because of a software problem but might be a hardware problem. Sad Mac errors occur before the Mac OS is actually fully active. Since the Mac OS isn't fully started at the time the error occurred, there is no way to give you the traditional "Your System Quit" message. Instead, you get a Sad Mac screen.
This particular error is the same as a "Type 1" error. The error could indicate that your System file is corrupted.
What to do
You should review the explanation of error “1” (using the “Mac OS Errors” option of the Tools menu).
If you suspect that the System file is corrupted, try re-installing it. If that fails to solve the problem, you are probably having a hardware failure. The System file can appear to be corrupted because of bad RAM or a bad disk. These possibilities can only be evaluated with certainty by an Apple Repair shop. Consider having your system examined if you don't feel capable of doing it yourself.
