Launch external merge tool but it does not actually launch anything


I try to use merge tool or diff tool DiffMerge but not start. Before I update to High Sierra all work.

I'm not compare remove o renamed file.

In the system log and in LittleSnich there is a warning that SourceTree is unknown signature or missing.

I start to think that this make OS to not start too cal by unknown software.

Am I correct?

Hi Saul,

We aren't aware of any signing issues on macOS, High Sierra or otherwise. Do any other diff tools work when configured?



BBEdit, FileMerge work

but DeltaWalker, DiffMerge not work.

I ask to a friend to repeat the same operation and have de same issue. He have High Sierra and older sourcetree.

I check the log and I see an error repeat when i call "External Diff":

Taskgated - MacOS error: -67062

I don't know but command: security error -67062 say:

Error: 0xFFFEFA0A -67062 code object is not signed at all




I forget if I launch by command line DiffMerge (

/Applications/ the windows of diffmerge open without any problem.
