Here is a little fix that I saw pertaining to running the Tizen emulator in Mac OS X Mavericks on a MacBook. The issue is that it may crash upon execution because HAXM is not currently supported by the Tizen emulator.
There are two ways to address this issue:
1. [Not recommended] Disable CPU-VT and GPU from the emulator manager as shown below. However, you have to know that doing this will make your emulator very slow but it will run peacefully.
2. [Recommended] Install hotfix for Mavericks available to download from the HAXM website:
