Flight From The City

I love this movie by Jóhann Jóhannsson.

“Allow your Apple Watch to unlock your Mac” not showing up after turning Two Step Verification off

Security and Privacy Preference Setting

Among all the new features of macOS Sierra that launched , it's “Allow your Apple Watch to unlock your Mac” I wanted to try first.

At first, it seemed really easy: just check the box labeled “Allow your Apple Watch to unlock your Mac” in System Preferences → Security and Privacy → General on your Mac. It turns out there are a few more loops to jump through if you have “Two Step Verification” turned on on your Apple ID. Checking the box failed with a message saying that this feature couldn't be enabled while “Two Step Verification” (2SV) was on.

I never realised Apple had two different processes with similar usability and slightly different names to strengthen security.

So I headed off to turn “Two Step Verification” off for my Apple ID. Turning this feature off prompts you to choose a new set of security questions (eventhough you might have done that previously before enabling Two Step Verification). Once that completed, it fires off emails to all your verified accounts warning that the security has changed.

When I returned to System Preferences → Security and Privacy → General on your Mac to enable the new feature, I discovered that the checkbox was gone… as if my devices didn't recognise each other anymore.

That is when I discovered that there was a “Two Factor Authtenication” (2FA)process available, which I enabled on my Mac through the security section of my Apple ID account. But the checkbox still didn't appear.

Rebooting all devices (Mac, iPhone, Watch) didn't help either.

It turned out you need to go in your iCloud settings to revalidate your Apple ID on all your devices. This means entering your Apple ID password in the iCloud setting (and in the Watch app on the iPhone), confirm it with a 2FA code, and revalidate it with your device password. Once all this completed, the checkbox reappeared in my Security settings on my Mac and I could unlock my Mac just by sitting in front of it.

I'm still a little perplexed by the complexity of the task at hand. Was I an edge case having 2SV enabled? Was 2SV launched before 2FA? I guess the latter superseeds the former , but it feels very unApple to offer two distinct processes so similar.

Goodbye Patricia Plattner

Made in india

Patricia Plattner died after a long battle against the big C.

I initially discovered her work through her films “Made in India” and “Les Petites Couleurs” before meeting her once in Carouge in Les Studios Lolos “Avec un «s», précise Aloys”.

She was a warm, generous and very humane person. Full of creative energy, inspiring (and sometimes disturbing) others, while staying simple and straitforward.

Eric's Archived Thoughts: Bittersweet

Once again, Eric Meyer's words touch me deeply. His talks about Joshua's first day of kindergarten, love and life.

"Our kids may not understand exactly what we're saying in those moments, but they know exactly what we're talking about[...]"

The moments and emotions Eric describes match closely those burned deep inside my own memory cells, eventhough I have not been through the ordeals him and his family have. He has a way with words that goes strait to my heart, and for a brief moment, we are completely aligned while I read his lines.

Thank you Eric for sharing your thoughts, may they be happy or sad, they are always true and deep, and inspire me in my own voyage through life.

Hello, my name is David Roessli. I am a freelance web designer and developer based in Geneva, Switzerland.

This weblog is an nth attempt to solve my multiple online personalities and weblog/rss feeds burnout issues. (more)


I have been contemplating the idea of upgrading my desktop Mac since this spring. The latest 27" iMac (Quad-Core) seemed the perfect candidate, but the release of Apple's 27" Monitor last September made me stick with the Mac Pro...
