Change default mail app in OS X

Here is the steps to change default mail app in OS X:

  1. Open Mail app.
  2. Select Preferences -> General. Under "Default email reader", select your preferred mail app.

I am running into a problem by following the steps: the default email reader changes back to the original mail app seconds after I made the change. Here is the solution that works for me. Open terminal. Copy and paste the following script.

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,user

Then try step 1-2 again, and it won't change back again!

 

 

 

 

 

Here is an outline of the paper.

We propose a numerical approach to solve the minimization problem of the hierarchical decomposition introduced by Tadmor [Ta15], using duality to treat with \(L^{\infty}\) norm inside. And then generate the uniformly bounded solution of \(\nabla\cdot U = F\) in actual computation.
