Can't delete keychain items with UI, but command line works fine When using the Keychain Access app, I am often unable to delete an Web form password item. I have tried hitting the delete key and going to Edit > Delete. In both cases, nothing happens, there is no error message.

I can delete the item if I use the command line version of the tool:

$ security find-internet-password -a "foo@example.com"
keychain: "/Users/simon/Library/Keychains/woodside-mbp.keychain"
version: 256
class: "inet"
attributes:
    0x00000007 &lt;blob&gt;="daw.apple.com (foo@example.com)"
    0x00000008 &lt;blob&gt;=&lt;NULL&gt;
    "acct"&lt;blob&gt;="foo@example.com"
    "atyp"&lt;blob&gt;="form"
    ...
$ security delete-internet-password -a "foo@example.com"
keychain: "/Users/simon/Library/Keychains/woodside-mbp.keychain"
version: 256
class: "inet"
attributes:
    0x00000007 &lt;blob&gt;="daw.apple.com (foo@example.com)"
    0x00000008 &lt;blob&gt;=&lt;NULL&gt;
    "acct"&lt;blob&gt;="foo@example.com"
    "atyp"&lt;blob&gt;="form"
    ...
password has been deleted.


If I now redo the search in Keychain Access, the item is gone.

I am running El Capitan 10.11.4 (15E65), Keychain Access Version 9.0 (55171.20.2), and
I notice you say, "If I now redo the search in Keychain Access…" implying that you began by searching when you weren't able to delete the item. Find it in the list without searching and then delete. It's just a dumb bug. I have found I sometimes can delete a single item after searching, but not multiple, and sometimes there's no problem at all. ¯\_(ツ)_/¯
