Apple Park: Designed to Isolate

Malcolm Crawford (Mastodon):

The open-plan floors make it hard to concentrate. The building is so large that getting from one meeting to the next eats real time out of the day. It’s common for people to run meetings with colleagues over Webex — colleagues on the same campus, sometimes no more than two hundred yards away.

Ironically, Apple Park replaced a campus that did far better on the same measure without ever trying to. Infinite Loop produced far more of the accidental, cross-team contact Apple Park was explicitly built to create. Working out why starts with what Infinite Loop got right by accident. It continues with what the research on office proximity says about why that kind of thing happens at all. And it ends with what Apple Park could become instead — including a version of the fix Apple already trusts enough to run for a hundred people a year.

[…]

There’s no obvious focal point for the whole site — most sections have their own sitting area and their own coffee bar, but nothing plays the role Caffè Macs and the IL1 coffee bar played together at Infinite Loop. Caffè Macs at Apple Park seats a thousand people and feels built for throughput, not conversation. Everything is organised per-segment rather than around a shared centre, which is convenient for the people in that segment and useless for the discovery-by-accident that made the old campus work.

[…]

By multiple accounts from people who were there during design and construction, the site was flagged as under-provisioned for meetings and conferences before it even opened.

Via Jason Anthony Guy:

Apple Park is a beautiful structure, but is not terribly conducive to focused or collaborative work. Even as an occasional visitor I found it overwhelming. Employees sit shoulder to shoulder, voices bounce off and bleed through glass walls, and privacy is a virtual impossibility. My friends and colleagues who worked there regularly found it difficult to be productive.

I worked in Infinite Loop (Building 3, 2nd floor) for thirteen years (right below Developer Publications, where Malcolm spent a good portion of his Apple career). I loved IL because its design made serendipitous encounters easy. Whether it was sitting outside Caffè Macs or in the IL 1 Atrium, I would inevitably bump into someone and have a conversation that furthered an in-flight project, sparked something new, or simply reinforced the social ties that bind colleagues.

It helped that at that time, Apple had perhaps 10,000 employees, most of whom were in or near IL. After iPhone came about and IL started getting locked down, much of the natural collaboration dissipated, disappearing behind badged doors and disclosures.

Ken McLeod:

IL provided a place to focus on your work[1], as well as seating spaces that are out of the flow of traffic where you can have an informal meeting[2]. At AP, every collaborative space is effectively in the middle of a hallway. That turns out to be enormously distracting, both to you and to those people trying to work in the glass bullpen right next to it.

Helge Heß:

“The IL1 atrium really was the crossroads of the company in those days” I really don’t think that this is true literally by any means. Assuming “those days” overlap with the time I’ve been there (pre Park). The XFs in IL have been extremely scarce. IL was way too small and overloaded, I’d actually say it was very similar to Apple Park. No one really wanted to work there in those tiny offices with multiple people 🤷‍♀️

Steve Hayman:

I loved the IL1 atrium. I’d sit there and hope that someone like MMalc would wander by, and they often did. It was a real destination for field people who didn’t get to visit the mothership very often. I miss that. AP had nothing like it.

Eric Schwarz:

I think of my days in college—most dorms residence halls were not air conditioned, so at the end of August, you had to open your window (often to place a box fan) and door to create some airflow. People walking through the building would meet by chance. Newer buildings tended to be less lively and more like a hotel—all the doors closed and rarely much activity. Through renovations, most of the buildings have had air conditioning added, dropping those interactions over the years.

Update (2026-07-22): Dr. Drang:

As you may know, the Lumon Industries building that Mark, Helly, Irving, and Dylan work in is a former Bell Labs facility in Holmdel, New Jersey. I first learned about the building several years ago, when I read Jon Gertner’s excellent history of The Labs, The Idea Factory. It’s a distinctive place designed by Eero Saarinen in the early 60s.

Bell Labs was known for the fruitful collaboration of its researchers, often started through chance meetings in the hallways of other Bell Labs facilities. The new Holmdel building was supposed to further that sort of teamwork, but things didn’t work out as planned.

I worked in IL1 for over a decade. The day I saw the open-plan spaceship, I knew I would never set foot inside. There are more rewarding ways to work in a barn.

High Performance mode allows sharing another Mac’s display as if your own

Glenn Fleishman, art by Shafer Brown

Apple’s built-in screen sharing support for Mac-to-Mac connections has always been a help for those of us with remote setups: headless Macs acting as servers, an office and home Mac, or the laziness of having Macs in different parts of your house you want to access without standing up.1

Under the hood, Apple relies on VNC (Virtual Network Computing), a fairly ancient standard at this point in time, and you probably get the sense of its creaking joints if you use the Screen Sharing app regularly.2 But it’s possible you didn’t know that, starting in Sonoma, Apple added a “super excellent” mode to Screen Sharing as an option when you connect two Macs with M-series chips. Called High Performance, it can deliver on its name.

Let’s shift into overdrive

A dialog titled “Select Screen Sharing Type:” with two radio buttons: Standard, described as “Works with most network conditions,” and High Performance, described as “Works with high speed networks only.” Standard is selected. Cancel and Continue buttons appear at bottom right.
When you initiate a connection, Screen Sharing asks you to pick between Standard and High Performance modes.

When you connect to another Mac using Screen Sharing, you’re given a choice of which mode to use. Let’s walk through the connection steps:

  1. Either launch the Screen Sharing app and double-click the Mac’s name in a list, or, in the Finder, Control-click/right-click the Mac’s name and choose Screen Sharing. (There are still more ways to start, too.)
  2. From the Select Screen Sharing Type options, you can select Standard, which is VNC-based, or High Performance, which adds Apple’s secret sauce on top.
  3. Click Continue.
  4. Enter your credentials.
  5. The screen appears, and you may need to enter your macOS account password on the remote Mac to unlock it.

In that pathway, if you choose High Performance, you’re presented with different options. You can also click the info (i) button to the right of an existing connection in the Connections window in Screen Sharing, and choose High Performance from the Screen Sharing Type pop-up menu to save that option for the next connection.

A connection settings dialog showing fields for Name, Server Address, and Username, plus pop-up menus for Screen Sharing Type set to High Performance and Display Type set to 1 Virtual Display, and Port 5900.
A saved connection’s settings let you change the sharing type, display configuration, and port after the fact.

With a Standard connection, you get a pixel-for-pixel remote view of the other Mac’s display or displays. It’s just like you’re sitting in front of it. In fact, if you use the same account as the currently logged-in user, the remote Mac shows what you’re doing to anyone who looks at it. (You can log in as another user, and a session starts in the background that doesn’t appear on the remote display screen.)

High Performance takes a different approach. You can opt to create one or two virtual displays on the remote Mac, each with independent resolution, high-dynamic-range (HDR) support, and other features. It’s like being a remote user of the computer rather than sharing. (This mode doesn’t change the remote display resolution or other settings.)

With a High Performance connection between Apple silicon Macs, you gain these advantages:

  • You can choose one or two virtual displays, regardless of the number of displays connected to the shared computer.
  • The Dynamic Resolution option lets you resize a virtual display to the native resolution of your local screen, up to 4K (3840×2160 pixels) or, with HiDPI, up to 1920×1080. You can click the Dynamic button on the Screen Sharing toolbar or choose View: Dynamic Resolution during a live session.
  • Stereo audio passes over the connection, as does improved video. The connection supports HDR (for richer low-light and shadow tones), 4:4:4 chroma subsampling (uncompressed color data for improved fidelity), and high frame rates of 30 or 60 frames per second (for more stable video streaming, such as when watching a video or using video-editing software).

The downside of High Performance is that it imposes severe requirements for it to work well. You need 75 Mbps per 4K display and low network latency, which requires fast Wi-Fi with a gigabit-or-faster mesh or wired backbone if there are multiple network routers or base stations. However, that requirement also means that when you’re using High Performance, it feels very much like sitting in front of the other display rather than viewing it remotely.

A toolbar in the Screen Sharing app with round icon buttons labeled Control, Dynamic, HDR, Apps, Mission Control, Desktop, Cursor, and App Windows. The Control button is highlighted in blue; HDR and Cursor are dimmed.
The Screen Sharing toolbar with High Performance mode enabled offers controls unavailable in a Standard session; some options remain dimmed depending on the remote Mac’s capabilities.

If you want the depth of HDR Video, you have to enable it on the remote Mac via System Settings: Displays. The option for HDR Video appears in a Preset pop-up menu, but, of course, only if the display supports the right HDR signal. HDR can be enabled or disabled from the View menu and Screen Sharing toolbar, if it’s available.

Because the remote display is blacked out when using High Performance (even when connecting as the currently logged-in user), this can be seen as a privacy advantage if you have concerns about anyone else viewing the remote Mac’s screen. However, High Performance mode’s utility really lies in treating Screen Sharing like a high-speed display tunnel instead of a jerky remote view.

  1. I don’t have a couch Mac and a kitchen Mac and a bedroom Mac and a… you get it. But I do have a downstairs office Mac and a laptop. ↩
  2. Screen Sharing is found in /System/Applications/Utilities, just an oddity of how Apple locates certain apps on the immutable System volume. ↩
