Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

How to setup iCloud+ Custom Domain Catch All email with Gmail

I've recently tested on how to move the custom domain catch all email from G Suite to the new iCloud+ Catch All feature and wanted to share my experience.

The end result is having Custom Domain email and Catch All routing, that can be fully used via Gmail, including receiving and sending emails.

The steps

Setup your Custom Domain (or subdomain) with iCloud+

	(defun formatted-copy (start end)
	"Export region to HTML, and copy it to the clipboard."
	(interactive "r")
	(let* ((region-string (buffer-substring-no-properties start end))
	(shell-command "pandoc -f gfm -t html5 \| pbcopy_html")
	(output-buffer (generate-new-buffer "Shell Command Output")))
	(with-current-buffer output-buffer
	(erase-buffer)
	(insert region-string)
	(shell-command-on-region (point-min) (point-max) shell-command t t))

	use AppleScript version "2.4" -- Yosemite (10.10) or later
	use scripting additions

	(*
	Original script: John Gruber (https://daringfireball.net/linked/2023/12/05/an-applescript-for-safari-split-tabs-to-new-window)
	Much more elegant version: Leon Cowle (https://github.com/leoncowle)
	Even more elegant version: https://stackoverflow.com/questions/54066100/applescript-to-split-safari-tabs-into-new-window/54089865#54089865

	Worth a warning: "moving" tabs with this script doesn't actually move them like
	drag-and-drop does. The tabs "moved" by this script will reload in the new window,

	1) Add this code to a new file in Script Editor
	2) Export the script as "Application" and make sure it's code signed
	3) Put "Startup.app" in the root folder of the test website (e.g. where index.html is located)
	4) Make sure that "Startup.app" has Full Disk Access in System Preferences > Security & Privacy > Privacy
