Hi Martin,
thank you so much for your reply to my question.
Here are some examples of what I am getting on my iMac:
1) I just brought up my mail program & this box came up:
sharingd wants to use your "login" keychain.
2) When I bring up Safari I get this message:
Safari want to use the "login" keychain.
3) I just wake my computer up from sleep & I get this:
com.apple.iCloudHelper wants to use the "login" keychain.
All of these boxes that come up, I have to hit Cancel a number of times before they go away.
My other option, of course, is to click OK, but I don't really want to.
Can I partially disable Keychain?
Also, wondering why you don't recommend disabling Keychain on my iPad & iPhone?
I look forward to hearing back from you,
Kathy
