I've recently been getting the following error when trying to run "bwlabel.m". Trying to run code that had been working as recently as a month ago. Any advice would be appreciated.

Running Matlab 2020b on Mac OS 10.15.7.

Unable to load bundle binary

/Applications/MATLAB_R2020b.app/bin/maci64/builtins/images_builtins/mwlibmwimagescore_builtinimpl.dylib. Error:

I was able to work around this problem on Mojave (10.14.4) by copying:

/Applications/MATLAB_R2020a.app/bin/maci64/libcudart.10.1.dylib

to:

/usr/lib

Delete and reinstall MATLAB, Reboot, and bwlabel should work again.

This workaround doesn't seem to work on Catalina and above because root cannot modify /usr/lib. Disabling SIP protection may get around this but so far I haven't been able to get my solution to work even with SIP disabled.

Hope this helps get us closer to a permanent solution.

The instructions in the Bug Report only ask to update to Matlab 2021a. What should we do if we cannot update the matlab version?

For other mac users who don't want to update MATLAB and don't have access to /usr/lib: I found that copying the library to /usr/local/lib did the trick, provided I also added an 'ad-hoc' code signature, eg:

sudo cp /Applications/MATLAB_R2020b.app/bin/maci64/libcudart.10.2.dylib /usr/local/lib

sudo codesign --deep -fs - /usr/local/lib/libcudart.10.2.dylib

Tested on:

R2020b on Big Sur (11.6.6)
R2019b on Mojave (10.14.6) - note libcudart version is different: libcudart.10.1.dylib

Note that this solution is just based on previous answers (https://uk.mathworks.com/matlabcentral/answers/1735020-library-not-loaded-rpath-libcudart-10-2-dylib#answer_982300 + https://uk.mathworks.com/matlabcentral/answers/403742-invalid-mex-file-and-missing-libmwblas-dylib-error#comment_1506540 ) + google + trial and error. I have no expertise in macOS code signing and would welcome thoughts from Mathworks or others on whether this is a sensible thing to do.

---

Update 22nd June: As pointed out by @Tyler Cumby in the discussion below, there is no need to move the file to /usr/local/lib - you can just run the codesign command directly on the relevant file

在 MATLAB Online 中打开

Thanks for the suggestion.

As I don't have access to /usr/lib/ on Catalina, I have tried moving the library to my working directory (and various other locations in the MATLAB path).

I can find the library with the command:

which libcudart.10.2.dylib

However, this does not eliminate the error for me.

I had this problem now too in R2020b.

I installed R2021a fresh and the problem is gone. Others say re-installing R2021b works too. Possibly any re-install would fix this.

A fresh installation of R2021a did not solve the problem for me.

Joss Knight 2022-6-13

Hi Pierre. MATLAB does not ship the offending library (libcudart) in R2021a so I'd be interested for you to elaborate more to help us work out what's going wrong for you. Perhaps you are running a MEX function?
