These omissions may prevent CVX from operating properly.

ERROR: one or more MEX files for this platform are missing.

These files end in the suffix ".mexmaca64". CVX will not operate

without these files. Please visit

And download a distribution targeted for your platform.

Based on the last lines of the error message, there is a support infrastructure by the CVX authors. I recommend contacting them.

Hello Wang,

I understand you're encountering an issue with installing CVX on a Mac with an M1 chip. The below error message indicating that MEX files with the suffix ".mexmaca64" are missing suggests that the necessary binaries for your platform were not included in the version of CVX you're trying to install.

 ERROR: one or more MEX files for this platform are missing.
    These files end in the suffix ".mexmaca64". CVX will not operate
    without these files. Please visit

Historically, CVX did not have support for the M1 chip in Macs, which meant that users with this hardware could only use CVX on an Intel-based MacBook or by running MATLAB through the Rosetta emulator, which allows Intel-based applications to run on Apple Silicon.

However, recently CVX has released a package that supports MATLAB versions starting with R2023b directly on Apple Silicon, without the need for Rosetta emulation. This means you should be able to use CVX natively on your M1 Mac with the appropriate MATLAB release.

For detailed information and instructions on how to download and install the correct version of CVX for your M1 Mac, you can refer to the following threads on the CVX forum:

I hope it helps to resolve your issue!
