Error when loading xlsx file in Mac OS

I'm trying to import some xlsx data to my workspace but the following warning keeps popping out:

Jun 09, 2023 7:01:14 PM com.jidesoft.plaf.aqua.AquaPreferences loadGlobalPreferences

WARNING: AquaPreferences failed to load Mac OS X global system preferences - parseInt: unsupported byte count:16

I've tried to upload the data manually or by programming but it won't appear in the workspace and create the .mat dataset. Any help would be much appreciated.

Thanks in advance.

I am finding references to this occurring on Big Sur, and one post hints it might have to do with using Apple Silicon cpu

Hi David,

I understand that you are encountering a warning while trying to import xlsx data. This warning originates from the JIDE package—a package that the MATLAB import tool calls.

Despite the warning, the data is still imported correctly into MATLAB and can be used as normal. You can disregard the message and proceed with your tasks without any interruption. If you would like to avoid the message, you may consider functions like “readtable” or “readmatrix” instead. These functions should not display the “AquaPreferences” warning as long as there are no shadowing issues.
