#Physical delete keychain mac install#
I followed the instructions here to backup the system keychain from my MacBook and install it on the iMac, but get an error saying "Operation not permitted".Ĭertain files have a property incorrectly set that will prevent them from being changed or deleted while the system is running. That is to say that I can freely edit, delete and create keys in the System keychain. I also have a MacBook, which is not exhibiting this problem. This being said, I would have no problem "resetting" the System keychain to default (empty) condition. My System keychain contains 20 items - all of which are either passwords to WiFis, passwords to Time Machines (which I want to delete), and one application password to the guest account.
