[TIMOB-13176] Tizen : Emulator fails to launch on mac osx gives 'not enough shared memory' error

NOTE: I am filing this issue as a blocker.This is a big issue,as its not our bug feel free to change the severity Description: 1.Follow the setup instructions on the tizen preview page here :http://ec2-50-16-19-245.compute-1.amazonaws.com/studio/tizen 2.Fire up an instance of the emulator Actual Result: 1.Starting the emulator gives "Cannot start this emulator, shared memory not enough" error & the emulator does not start 2.On doing some research I found a workaround where we have to manually add some values to the 'sysctl.conf' file by sudoing in the file (basically increase the shared memory manually) 3.The tizen jira ticket for the same : https://bugs.tizen.org/jira/browse/TSDK-81 4.This workaround worked for me : http://stackoverflow.com/questions/15000628/tizen-emulator-not-running-in-tizen NOTE: I don't know if its hardware dependent, but my machine has good hardware.This is a big usability issue. Expected Result: 1.The emulator should launch without any errors
