Error thrown by Step 8

bobwhosmiles opened this issue 5 years ago · comments

Mac model: MacBook Air (11-inch, Early 2015)
iPad model: iPad Air 2

Mac version: Catalina 10.15
iPad version: iPad OS 13.1.3

At Step 8 in the instructions I get the following:

/System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore: replacing existing signature
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: object: /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore malformed object (unknown load command 8)
/System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore: the codesign_allocate helper tool cannot be found or used

Any ideas?

Restore the original SidecarCore and do xcode-select --install to install the developer tools. Then copy the patched SidecarCore into the system folder again, then try codesigning.

Try not to leave unsigned SidecarCore in the system folder because it will crash applications that try to load that framework.

Thanks Ben. Followed these steps, dev tools installed successfully, but still getting the same error when trying to sign the patched SidecarCore

Interesting 😮. Try xcode-select --reset. (source: maciekish/iReSign#95)

Ran sudo xcode-select --reset then repeated the codesigning - still that same error. Baffled but thanks for trying to help :)

Ah the second line might be indicating that the SidecarCore file wasn't properly modified!

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: object: /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore malformed object (unknown load command 8)

Can you post your original and the modified SidecarCore binaries here for inspection?

(If you haven't, try to patch the original file again to see if the file is just accidentally corrupted)

Tried all steps again from scratch but still getting an error:

Bob@Bobs-Air ~ % sudo codesign -f -s - /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore
/System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore: replacing existing signature
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate: object: /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore malformed object (unknown load command 8)
/System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore: the codesign_allocate helper tool cannot be found or used

I've attached the original and modified files as suggested. Thanks Ben

Weird. I was able to sign your binary on my system without any errors! After reading this, I'm suspecting that your Xcode may be outdated. Try downloading/updating Xcode from the App Store and make sure it's Version 11.1 (11A1027) or newer.
