This is Yuhong Zha from the Kihara Bioinformatics Laboratory. We are currently developing a Chimera extension to implement our MAINMAST algorithm. However, when I update my Chimera to the newest version, I started to get permission errors. I'm using a Mac.</p>

In our extension, we have some code involving editing files like "os.remove(filename)". However, after the update, the extension receives error "Operation not permitted" when executing those lines.</p>

I think one possible reason might be improper updating steps. After the update, I started Chimera directly from installer instead of drag the icon to my folder. Then this error occurs. Later, even when I deleted the Chimera by dragging it to trash and deleting
trash, and then re-download and install Chimera, the error still occurs.</p>

We have 2 Mac made the update but only one of them has this error. Do you have any clue why this happens?</p>
