Crash on Launch under macOS 10.13 High Sierra

[l008com]

The Curecoin wallet app crashes instantly at launch when running on MacOS 10.13. The problem is repeatable on 2 separate Macs both running 10.13. This is what I get from the crash report:

Crashed Thread: 0 Dispatch queue: com.apple.main-thread

Exception Type: EXC_BAD_INSTRUCTION (SIGILL)
Exception Codes: 0x0000000000000001, 0x0000000000000000
Exception Note: EXC_CORPSE_NOTIFY

Termination Signal: Illegal instruction: 4
Termination Reason: Namespace SIGNAL, Code 0x4
Terminating Process: exc handler [0]

... which means nothing to me but hopefully it means something to you guys. I tried 2.0 and 2.0.0.1 also and had the same problems. Seems to run on 10.14 just fine. shrug
