That's not necessarily a bad thing, as a single port can daisy chain six devices. It also makes it possible to use multiple external displays with an Apple notebook for the first time—at least without resorting to workarounds like USB video adapters. As we noted, the latest MacBook Airs use a smaller Eagle Ridge controller that only has one DisplayPort channel, so these machines are limited to just one Thunderbolt or miniDP display, period. You can easily daisy chain two Thunderbolt Displays to a single Thunderbolt port on these machines.
There are a couple exceptions. The 13" MacBook Pro can only drive two displays total with its integrated Intel HD graphics, so if you plug in two displays, the built-in screen will go black. On 15" and 17" MacBook Pros and iMacs, the main screen will continue to function. Despite having two Thunderbolt ports, the 27" iMac can still only use two external displays, regardless of whether they are daisy chained or plugged in to separate ports.
Though it has two ports, both are wired to a single Light Ridge controller, so there are only two DisplayPort channels total. What is really going to rub folks the wrong way, we suspect, is that the Thunderbolt Display is not configured to work with a miniDP display plugged in to its Thunderbolt port. It wouldn't be surprising if more than one user with an existing 27" Cinema Display or other miniDP display got a Thunderbolt-equipped Mac and ordered a Thunderbolt display expecting to be able to add the miniDP display at the end of the chain.
Adding a miniDP display at the end of the chain works with other Thunderbolt peripherals that have downstream ports, so it's not a technical limitation of the spec.
A more unfortunate side effect, we believe, is that not working according to the spec will add consumer confusion and hamper what is beginning to be a wider rollout of the technology in the PC industry. Though this at least demonstrates that it is possible to drive a miniDP display connected to a Thunderbolt Display, it still looks like a needlessly confusing limitation to require another Thunderbolt device in the chain.

Kind of strange move to imply that you have to purchase everything new again. Naturally, this is the kind of thing that happens when you re-use connectors for different interfaces, but in another year, we'll be pointing to the present flock of devices as being somewhat awkwardly transitional and move on. It also seems like if they were aiming for a graceful transition, they could have made the Thunderbolt display able to accept a Mini DisplayPort signal from slightly older Macs. AFAIK, you'd be able to cable this together but it wouldn't work as deet said, "this is the kind of thing that happens when you re-use connectors for different interfaces.
I'm in the market for a new display and am tempted by these nice Apple 27" ones, but this new one won't work with any computer I currently have, and I don't want to spend the same price on the old model which won't have the nice Thunderbolt features for the next Mac I buy.

The size is damn near perfect for what I do, and I especially like the arc in the front. Do you get that much comfort out of it?

Is it better for your back or posture? I use a kind of junky generic office chair, I have long wondered if the fancier chairs are worth the hefty expense.

Absolutely it is. It is definitely something I want to duplicate in my home office when I upgrade from my inch iMac. Thanks so much for the inspiration!! Thanks for posting this. Sweet setup. This post confirmed my choice. Mac Mini i7 quad 2. Apple is separating the new smartphones into its usual low-cost versus high-cost categories, with big differences between the two models coming down to the camera, display, and battery life.
At first glance, the two devices have quite a few similarities, but the iPhone 11 takes a step forward in regards to cameras, battery life, and more.

With the new 27" Apple Thunderbolt Display now shipping to customers , Apple has posted a new support document outlining what can and can not be accomplished with multiple monitors on Thunderbolt-enabled Mac systems.
As far as compatibility, Apple notes that all Thunderbolt-enabled systems with the exception of the MacBook Air can handle two Thunderbolt displays, with a caveat for the inch MacBook Pro being that the computer's internal display will not function if two Thunderbolt displays are connected. This is expected behavior.

One other note of interest that will be a disappointment for some users is the disclosure that users will not be able to daisy chain a Mini DisplayPort display off an Apple Thunderbolt Display. Mini DisplayPort displays will not light up if connected to the Thunderbolt port on an Apple Thunderbolt Display inch. The revelation is a bit of a surprise, as Mini DisplayPort displays can currently be daisy chained off other Thunderbolt peripherals.
Some users had been hoping to reuse their existing Mini DisplayPort displays as part of multiple-monitor setups using the new Thunderbolt display, but will apparently be unable to do so.

Finally, Apple recommends that users daisy chaining the Apple Thunderbolt Display with Thunderbolt storage devices connect the display directly to the computer's Thunderbolt port, with other peripherals daisy chaining off of the display. Update : Macworld appears to have demonstrated that you can indeed daisy chain a Mini DisplayPort monitor as long as it is connected to some other device than the Thunderbolt display. It is unclear why simply inserting another Thunderbolt device into the middle of the chain allows the Mini DisplayPort display to function, but at least one MacRumors forum member has confirmed that he is unable to daisy chain his Mini DisplayPort-enabled Apple Cinema Display directly off of the new Thunderbolt display.
