indexImages() fails to run

I try to run

indexImages(imageDatastore(folder_images));

I am following this tutorial page. But I get the below error... I am not sure how to proceed any help would be much appreciated!

Which MacOS are you using?

Currently on Yosemite 10.10.5 and can only update to at most High Sierra due to my mac model. Thanks for your response, further suggestions are appreciated!

I just uninstalled and reinstalled matlab, but am still getting the same issue.

It appears using these lines helped others, but I am not sure where to add them...

export  LDFLAGS="-mmacosx-version-min=10.9"   
export   CFLAGS="-mmacosx-version-min=10.9"   
export CXXFLAGS="-mmacosx-version-min=10.9"

R2018b requires at least Sierra

Thank you, problem solved! Thought I could avoid updating, but ended up updating to High Sierra and glad I did! If you want me to accept your solution of updating as an answer (if you post as an answer instead of as a comment) I would be glad to! Have a great weekend Walter and thanks for all of your contributions to the Matlab community!
