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 "/Applications/Sound Forge Pro.app/Contents/MacOS/Sound Forge Pro" (cs_mtime:1365521695.0 == mtime:1365521695.0) (signed:1 validated:1 tainted:1 wpmapped:0 slid:0)

Is there any way to "reset" Apple's code signing and allow this application to run again?

Solution 1:

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.

Solution 2:

Here's a couple workarounds to try if you can't find an answer:

1) Time Machine

Use a Time Machine backup from before you upgraded as a system restore point.

2) Temporary User Account

Create a temporary user account, see if the error still occurs when logged into the temporary account, and if not, return to the Finder and enter:

  shift-command-g

and in the field that appears type:

  ~/Library

and in the window that appears, take a look in these folders for preferences for the name of app in question, or the name of its developer:

 ~/Library/Preferences/
 ~/Library/Application\ Support/
 ~/Library/Caches/

and copy these files into a folder with a duplicate folder structure:

 /Users/Shared/mytempLibrary/Preferences/
 /Users/Shared/mytempLibrary/Application\ Support/name.of.folders
 /Users/Shared/mytempLibrary/Caches/name.of.folders

Log out and back into your main account and use the files you copied to /Users/Shared to replace the same files in your ~/Library by reitering some or all instructions in proper sequence to accomplish this.
