10.10 compatible ?

Hi, I’ve just tried running this project under 10.10 and I get the following error:

2016-06-15 17:08:24.041 MachInjectSample[2454:31915] Injecting Finder (317) with /Users/johnholdsworth/Library/Developer/Xcode/DerivedData/MachInjectSample-geshmsepcxcvcedqvwrajxmdtfja/Build/Products/Debug/MachInjectSample.app/Contents/Resources/Payload.bundle

Is this expected with SIP and the like? Everything was signed with a valid Apple dev id.

I cloned your project and then copied in mach_inject/{mach_inject,mach_inject_bundle,mach_inject_bundle_stub} from https://github.com/rentzsch/mach_inject, then tried: git clone https://github.com/erwanb/MachInjectSample --recurse-submodules

This project has been fixed to work under 10.10, see this issue.
You can find it here.

Thanks for the prompt reply. Will the project work under 10.11 do you know? I’ve not had any luck

I don't follow the subject closely, but it seems Apple with SIP is determined to crack down on code injection.
Check this issue for a possible solution.

Yes, it seems the only answer is to turn SIP off. Thanks again.
