If you have a MacBook Pro with a Retina display, you may notice that in R2013b text is displayed less crisply than earlier releases of MATLAB.

I find that the text is significantly less sharp in R2013b than in R2013a on a NON-Retina display MacBook Pro. Is there anything that can be done about that?

This is the case. R2013b looks less sharp than earlier releases of MATLAB on MacBook Pros with a Retina display. MathWorks is aware of the issue; more information can be found at:

Allow me to be more frank: 2013b looks borderline unusable on a Retina display. It's like reading without glasses (for those who need them). I would not upgrade until a fix is available.

For those running r2013b on a retina Macbook: the blurry interface is caused by an outdated version of Java that ships with this release (as oppose to previous releases, which used the system Java runtime). You can easily change the Java runtime used by Matlab to a more recent version. This solves the blurriness on your retina Mac.
To do this, first locate the path to your system Java runtime (JRE), for instance:
/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/jre
Then set the environment variable MATLAB_JAVA to this path. Follow the instructions in the following article if you don't know how to do so:

After rebooting, r2013b will no longer look blurry.

Thanks for the advice! I've replaced the jre folder with a symlink to the jre from my jdk (7u51), and MATLAB now looks good on the Retina display and on a 4K monitor I have running in HiDPI mode. However, Simulink still does not seem to be taking advantage of it and still looks very pixelated. Do I have to repeat this procedure somewhere else for Simulink?
Thanks!

Using R2014a on Macbook Retina.
I have corrected the sharpness on Matlab editor and all the popup windows by replacing the JRE file. The problem is that in SIMULINK and STATEFLOW the fonts are still blurry until they are selected. When a blurry line name, box name, or command is selected it instantly sharpens into focus. As soon as it is deselected it returns to blurry. Please help....

Thanks Erik. Your second approach works perfectly.

It causes other problems as well. At least for me, in Mavericks using java 1.7 51, zooming into plots often beachballs. Unusable.

Cursor placement and text spacing may be fixable by changing fonts. I switched to Meslo LG for my fixed-width font, and all the text fields look great now; no cursor issues.
Stability is a problem for me. Occasional plot issues, and using help() at all is an instant beachball. But I'll put up with a couple crashes a day to get a readable display. Just hope this is fixed soon.

Another workaround is to run the Windows version of Matlab in a virtual machine on your Mac. Retina support (called "Hi-DPI" in Windows parlance) works mostly fine out of the box on the Windows side for R2014a on Windows 7. (You just need to adjust your font sizes. And the ribbon is displayed really small.) It doesn't seem to have the stability issues that running OS X Matlab against a newer MATLAB_JAVA does.
I'm running OS X 10.9.2, Windows 7 SP1 in a VM under Parallels Desktop 9, Matlab R2014a.
