App hangs when run: cs_invalid_page error in logfile I'm trying to start Sony Sound Forge Pro. It's worked before, but then I tried to update to version 2 of the app, and I started getting this error when I start it. I downgraded back to version 1 and I still get the error.
The error is in the Console and it looks like this:

5/1/14 8:15:25.000 PM kernel[0]: CODE SIGNING: cs_invalid_page(0x10d2c1000): p=490[CoreServicesUIAg] final status 0x1000a00, denying page sending SIGKILL
5/1/14 8:15:25.000 PM kernel[0]: CODE SIGNING: process 490[CoreServicesUIAg]: rejecting invalid page at address 0x10d2c1000 from offset 0x11000 in file &quot;/Applications/Sound Forge Pro.app/Contents/MacOS/Sound Forge Pro&quot; (cs_mtime:1365521695.0 == mtime:1365521695.0) (signed:1 validated:1 tainted:1 wpmapped:0 slid:0)

Is there any way to &quot;reset&quot; Apple's code signing and allow this application to run again?
You could ad-hoc sign the program yourself if you know it is a valid program, and not malware or similar.

From Terminal.app run a command like this:

sudo codesign -f -s - "/Applications/Sound Forge Pro.app/Contents/MacOS/Sound Forge Pro"

"-f" means to force replace the existing, faulty, signature
"-s -" means to ad-hoc sign

The rest is the completely path and filename of the executable you want to sign.
