Exporting WiFi Keychain

[chefwong]

When using migration assist, I believe it brings back keychain.

If starting fresh on a new notebook and not looking to do migration assist, I don't see a way to export keychain data. Is there a way.
All I care about is the WiFi Keychain

If you had key chain enabled in iCloud preferences on the old Mac it should sync on the new Mac?

 

[chefwong]

No. AFAIK. Last time I did this on a new mac, icloud-keychain sync enabled, and connecting to Wireless networks on New Mac would not connect . However, saved WiFI networks on IOS keychain works, but apparently under OSX, WiFI under keychain is not part of iCloud sync. I know it works as every new phone/iPad I have bought just works across all networks..

Just set up new Mini by migrating from Time Machine and the keychain was transferred, including older wifi connections.

TM or using the Migration Assistant will bring WiFi Keychain back.
New Mac - want to start clean. All I want to -bring over- is just the WiFi keychain. But yes, TM or Migration Assistant will bring that over.

I went through this process last time I got a new MacBook. Like you I want to start clean. I know I can import them, but this time around I'd like to just have a list of all of them in a text file or whatever. Lots of utilities on Windows that will do this. When I search for how to do it on the Mac everyone has a howto on how to read them out of keychain, ONE AT A TIME.

I already know how to do that.

Anyone know of a script or utility that will read them all out? I've got a bunch.

It's been awhile but I ended up completely fresh.
TM afaik, is the only one that will definitely do it.

Using System Migration, and I for but it was *system settings* or the like in the options, it did not carry it over. Wishful thinking I know.

I found a way to get all 381 WiFi passwords. I used the script here:

MrC's Convert to 1Password Utility (mrc-converter-suite) - Page 44

@scottypa , Ok, sorry for the inconvenience. Can you try this for me and let me know if it works out?

1password.community

I ran that in Script Editor. Opened Keychain Access and clicked on the Local Items keychain. Searched for "Airport network password" to get it to display only WiFi passwords and not everything else. Also sorted so that it would go through Local Items then System. The script only works for Local Items. The System items are duplicates best I can tell and they require an additional username and password to reveal.

I modified the script to run 100 at a time. Sometimes Keychain Access would close its window after a batch. Also I cut out the "account" step as it was redundant. i.e. the original script would create
WiFi name, WiFi name, password.
After I removed the account step from the script I just got
WiFi name, password.
