MATLAB

I am attempting to start MATLAB R2017a, which crashes on startup on macOS with a similar stack trace:

This is a known issue with MATLAB R2017a on macOS and has been fixed in MATLAB R2017b.

See the following bug report, which provides a patch and instructions on how to fix this problem:

MATLAB can sporadically crash when started on a Mac

https://www.mathworks.com/support/bugreports/1549820

If your Mac crash does not have this stack trace then please look at this article for generic MATLAB crashes on Mac.

Why will MATLAB not start up properly on my Mac?

If you continue to have issues with MATLAB after following the bug report above, contact the MathWorks Licensing and Installation Support team for assistance.

MATLAB: Does MATLAB crash at startup on macOS 10.12 Sierra or later

This crash can be traced to the following file being missing or corrupted:

/Applications/MATLAB_R2017b.app/settings/src/settingscore/settings.xsd

To correct this issue, reinstall MATLAB on your machine. You will also want to remove or rename the /Users/$USER/Downloads/MathWorks folder on your machine to ensure that complete installation files are downloaded, and to rule out any potential problems caused by corrupted installation files.

MATLAB: Matlab R2017a (9.2.0.538062) crashes when calling functions from the Parallel Computing Toolbox (MacOS Sierra 10.12.5)

The error may be a result of the ulimit settings being too low.

To check ulimit, open Terminal and run the following:

>>ulimit -a

If you see that the "max user processes" and "open files" are set to low values (For example, open files (-n) 256, max user processes (-u) 709), please raise those two values to be able to open larger pools. The ulimit command can be used to set these values, run ulimit in Terminal and it will identify which switches to use to make the changes. With the move to El Capitan and newer OS X and macOS you may not have the ability to make these changes due to restrictions in place. Creating plists for each of the settings will allow this however.

Create the following files:

/Library/LaunchDaemons/limit.maxfiles.plist
/Library/LaunchDaemons/limit.maxproc.plist

Content of the files should be as shown bellow:

limit.maxfiles.plist:

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"  
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">  
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>524288</string>
      <string>524288</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>

and the second one for limit.maxproc.plist:

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE plist PUBLIC "-//Apple/DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">  
  <plist version="1.0">
    <dict>
      <key>Label</key>
        <string>limit.maxproc</string>
      <key>ProgramArguments</key>
        <array>
          <string>launchctl</string>
          <string>limit</string>
          <string>maxproc</string>
          <string>2048</string>
          <string>2048</string>
        </array>
      <key>RunAtLoad</key>
        <true />
      <key>ServiceIPC</key>
        <false />
    </dict>
  </plist>

Once the files have been created change the ownership to root:wheel:

>>sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
>>sudo chown root:wheel /Library/LaunchDaemons/limit.maxproc.plist

Next load the plists:

>>sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist
>>sudo launchctl load -w /Library/LaunchDaemons/limit.maxproc.plist

Once complete reboot and run ulimit -a again in Terminal and these two options should be increased.

Try validation and parpool again.

If the errors persist please contact MathWorks Installation Support:
