exit status 1 on Mac OS X, go test fails

[kiwih]

When calling CPUPercent on OS X (Darwin) I get an error returned with the message "Exit status 1".
Tracing it through gopsutil reveals that doSysctrl() with argument "kern.cp_time" is throwing an error.
This is because OS X doesn't have "kern.cp_time" in /usr/sbin/sysctl

As a result, go test fails on OS X.

    cpu_test.go:13: error exit status 1
    cpu_test.go:16: could not get CPUs  exit status 1

It seems host_processor_info() is required to get CPU information on darwin. I will try to use it. please wait for a while.

👍 Experiencing this error as well

Sorry to keep you waiting, I just implement CPUTimes on darwin, by adhoc compiling the tiny c program which can output cpu times. This is very hacky way, but it works, I think.

Due to the #57 (thanks for pquerna), it only enabled when ALLLOW_INSECURE_CPU_HELPER set to "yes".
This behavior is temporary. When I find another way, it will be changed completely.

Thank you

Since I change to use CGO on darwin, close this issue. If you find something, please re-open. Thank you.
