Hi. I tried mach_inject + some Finder integration code on Mac OS X 10.10 Yosemite (Beta6) - and it fails in injected thread, on the first fopen/freopen/fwrite function call.
Everything works fine on Mavericks.

Anyone more experienced tried to run mach_inject on Yosemite? Or, somebody can recommend a way to debug this issue?
Thanks, all input is appreciated.
