Thank You for posting this guide. I own a TX201LA and might give OSX a try on it now that you have completed this very through install guide. AWESOME WORK!!!!!!!!!!!!!!!!!!!
Also I wonder if you are aware of the TX201LAF model. It recived an update to android 4.4 over 4.2 for the US model. Asus has it on there site here:
The problem is trying to mod the model to accept this update to android 4.4. I know now it may not seem like much of an update for 4.2 but it really is. 4.4 is as fast as 5.0 as for speed. It does not have all of the 5.0 features but it has most of them. I have tried to update the firmware to 4.4 using the LAF model info but need help. Are you interested in getting this done?
Also I should add that the TX201LA has the exact same CPU & ram as the Asus zenphone 5, which has updates to android 6. So theoretically there should be able to mod that firmware to run on the tablet.
