The web has a lot to see. Safari helps make sure “you” aren’t one of the things being watched.

[Ethan Agarwal @ethanagarwal]

You lost our trust.

The people in CA-17 are too important.

Agarwal for Congress.

[Greg Joswiak @gregjoz]

All systems glow for a great #WWDC26 next week!

Tune in June 8 at 10 am PT.

[Gabriel Jacoby-Cooper @GerzerSoftware]

I voted for @ethanagarwal for Congress in CA-17! #RoMustGo

🔺NEW: Formally verified post-quantum ML-KEM and ML-DSA in corecrypto, with correctness proven from the FIPS spec down to hand-optimized ARM64 assembly — a world first at multi-billion device scale. And we're releasing our Isabelle libraries, ARM64 model, and Cryptol-to-Isabelle translator to advance the state of the art in verified cryptography! https://t.co/LZPHFD0ifE

The shooting needs to stop. Hate crimes are rampant, and not enough people seem to care. The latest one in San Diego was too predictable these days.

Khanna is most well known for two things: speaking in third person and having no principles.

[Brianna Wu @BriannaWu]

As a trans woman, I understand that if the Democrats don’t win 2028 I probably won’t have a future in this country.

Which is why the judgment we are showing running someone with A LITERAL NAZI TATOO is so extremely concerning. We knew about this months ago. There was plenty of time to find a non-Nazi candidate.

But we did nothing. The Bernie faction won. And it’s another signal to normal Americans that we’ve lost our minds.

At some point, we have to face reality. Our party cannot make coherent tactical decisions. It’s why we ran Biden when every poll showed she could not win, and it’s why we refuse to course correct after losing.

I need us to be less suicidal.

[CONTROL Resonant 🔻Pre-order Now! @ControlRemedy]

@tim_cook 🙏 It’s so good to be home

[Greg Joswiak @gregjoz]

Welcome home to the Artemis II crew! Honored that NASA astronauts brought iPhone to space with them. One small step for iPhone. One giant leap for space selfies. 🚀📱

[Tim Cook @tim_cook]

Congratulations to Artemis II on a successful mission! You captured the wonders of space and our planet beautifully, taking iPhone photography to new heights, and we’re grateful you shared it with the world. Your work continues to inspire us all to think different. Welcome home!

The Medical Imaging Calibration feature for Studio Display XDR is now FDA cleared & available on macOS 26.4 in the US! That means radiologists can use the world’s best pro display in general radiology. Incredible to see the intersection of health & technology. 🩻

[Gabriel Jacoby-Cooper @GerzerSoftware]

It was so exhilarating to attend the concert last night! #Apple50

[Tim Cook @tim_cook]

So thrilled to celebrate #Apple50 with @paulmccartney! His music has inspired us from the beginning, so this is a full circle moment to close out our celebrations. Thank you, Paul, for proving that when you think different, you have the power to change the world.

[Tim Cook @tim_cook]

50 years of Apple, 50 years of innovation.

Thank you to our teams, our users, and everyone who’s been part of the journey. #Apple50

🚨 The push to gut California’s landmark K–12 antisemitism law (AB 715) is being led by CAIR-CA, AROC, JVP, and others—groups with a documented record of the very antisemitism the law was meant to address.
