    Hi there

    El Capitan seems to have tightened security/ admin permissions even more. I tried to get "write" access on certain Apple apps (to exchange their icons) that I had in Yosemite but no longer can as it tells me "you do not have the required Administrator permissions..."

    Despite me being the Admin and no other accounts.

    How do I gain full read & write permissions? I assume it's some sort of terminal commands?

    Oh. In order to change those protected files, you need to boot to recovery partition, use csrutil to disable rootless, and then go back to edit. This seems that the only "officially supported" way to edit system files.

    Hence, if recovery partition is not bootable, or lost, it would be a great trouble to disable rootless when needed.
