Don't refer to it as fixing it, please, but you can use DDB to lower
it if you want. I do this sometimes. For example:
dima@hornet% sudo sysctl -w kern.securelevel=2
kern.securelevel: -1 -> 2
dima@hornet% Debugger("manual escape to debugger")
Stopped at Debugger+0x34: movb $0,in_Debugger.396
db> w securelevel 0xffffffff
securelevel 0x2 = 0xffffffff
db> c
/sbin/sysctl kern.securelevel
kern.securelevel: -1
dima@hornet%
If you're at a loss at what all of this does, I suggest you use one of
the other methods that were presented to you.
