v4.0.1 fails to start on OS X 10.10 and 10.11

[simongregory]

I haven't been able to confirm this as I don't have access to machines running the relevant versions of OSX, but our latest build (based on v4.0.1) has been reported as failing to start on OS X 10.10 and 10.11. Later versions are fine. Using your Electron binary directly the same failure is noted - a system dialog advising the user to contact the developer because there's been a problem.

This looks like the most relevant section from the OS report on the failure:

Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

Application Specific Information:
dyld: launch, loading dependent libraries

Seems like this is a known issue with some versions of the macOS 10.12 SDK (see electron/electron#16429 and linked issues), so we are probably using a version with this issue on the build machine.

I'll see about getting this fixed for v4.0.2-wvvmp, which is in the works.

I just published v4.0.2-wvvmp which fixes this issue (verified on a macOS 10.10 machine I managed to dig up).

Let me know if there are any further complications!
