When was mac unibody released

When the MagSafe power adapter is not connected, this MacBook draws power from its battery. The length of time that you can run your MacBook varies, depending on the applications you use and the external devices connected to your MacBook. Turning off features such as AirPort Extreme or Bluetooth wireless technology can help conserve battery charge. However if the battery runs low while you are working, you should attach your power adapter immediately and let the battery recharge. You can determine the charge left in the battery by looking at the battery level indicator lights on the battery itself.

Press the button next to the lights, and the lights glow briefly to show how much charge is left in the battery. You can check the charge with the battery in or out of the MacBook. Important note: If only one indicator light is on, very little charge is left. If this happens, plug in the power adapter to let the battery recharge, or replace the drained battery with a fully charged battery.

The amount of battery charge left can also be checked by viewing the Battery status icon, which will be found in the menu bar. The battery charge level displayed in the status iconis based on the amount of power left in the battery with the applications, peripheral devices, and system settings the user is currently using.

If you prefer to conserve battery power, you should close applications and disconnect peripheral devices not in use, then adjust your Energy Saver settings. Charging the Battery: When the power adapter that came with your MacBook is connected, the battery recharges whether the computer is on, off, or in sleep.

To replace the battery: Place the right side of the battery into the battery compartment. Gently press the left side of the battery down. Use a coin to turn the latch a quarter turn counterclockwise to lock the battery into place. It is possible to add two 2 GB memory modules for a maximum of 4 GB of memory. For best performance, the user can fill both memory slots and install an identical memory module in each slot. Important warning: Apple recommends that the user invites an Apple-certified technician install memory.

Consult the service and support information that came with your computer for information about how to contact Apple for service. If the user attempts to install memory and damage the equipment, such damage will not covered by the limited warranty on the computer.

Tap to click is usually on by default on Windows PCs, and off by default on the Mac. It's often just too easy to inadvertently tap to click, which can be particularly annoying when editing text and trying to position the cursor. One false tap and you're potentially selecting a line or typing into the wrong paragraph. Bottom line: virtual click taps seem to be improved while the "entire trackpad as a physical button" idea seems to have inconsistent and flawed behaviors, although this might only be an early adopter software flaw that can be fixed.

As with any input device, the new trackpad takes some getting used to, and the highly configurable settings should help most people find their happy place between gesture complexity and feature completeness.

Users who want a very simple trackpad may be frustrated with the inconsistent mechanical click action which again appears to be a software problem that can be fixed, not a hardware limitation , while extreme power users might be disappointed that the trackpad's gestures don't go far enough or allow enough customization.

Unlike the MacBook and its missing FireWire, the new MacBook Pro retains everything from the previous model, with some key differences. There's now no longer a separate FireWire and FireWire port; only the faster one. This may result in some users having to invest in a few bucks to get a FW to FW cable, but the daisy chain architecture of FireWire prevents the single port from really being a problem.

FireWire can also be used with a hub to support lots of devices. The faster speed of FW makes it nice that Apple kept the jack on the Pro model, although many users would have liked to see a MacBook Pro in the 13" size as well. All ports are now on the left side, so rather than having one USB port on each, there's two next to each other.

The other difference in port arrangement is the new Mini DisplayPort, which replaces the much larger DVI port on the previous model. Future iMacs, minis and Pros will also get the new port, likely making it common enough to find straight cables rather than having to use a dongle to connect to DVI or VGA.

The new models apparently provide no support for audio over a Mini DisplayPort cable as can be supported in the specification , so unlike Apple TV there's no way to output both audio and video over the same cable in the manner of HDMI. That necessitates also using the headphone audio output or a digital optical toslink port for audio output to a TV display. The headphone jack now also supports iPhone-style headphones with an integrated mic and a playback control button.

That's a great feature for anyone doing iChat audio or video conferencing or using another VoIP program on the go, as the built in microphone makes it hard to isolate background noise, and most mics and headsets designed for generic PCs lack the higher line level output required by the Mac's mic input port.

Removing the battery is nearly as easy as previous models. Rather than unlatching two catches, you flip a lever on the back to remove the cover and simply lift the battery out.

The cover also provides some additional protection against casual battery theft, as an attached locking cable prevents the back cover from being removed. The battery cover panel is extremely thin, making it fairly easy to bend out of precision alignment. It feels slightly thinner than the back panel of the Titanium PowerBook.

The battery unit is smaller and therefore lighter, which contributes to the new model only weighing a tenth of a pound more than the previous model, despite its heavier aluminum shell. The advance of using NVIDIA's controller for graphics, rather than a dedicated GPU by default, also pares down the battery demands of the new model enough to retain its same rated battery life. On the other hand, the battery simply has less capacity 50Wh versus 60Wh , so you're more likely to need to carry a spare, particularly if you hope to enable the higher performance of the dedicated GPU.

The internal battery now presents a signal level on the side of the unit, with eight LEDs rather than five on the previous model's batteries, offering some additional accuracy. However, loose batteries now lack any built-in indicator to show if they are charged or not. The MacBook Pro's battery bay hard drive is now removable with a single screw, rather than requiring the entire back to be taken off first.

Apple offers a and GB hard drive as standard, respectively, on the good and better models. It also offers upgrade options to a faster RPM hard drive or a smaller capacity, but much faster and pricier SSD. Above the battery bay cover is the main cover held in place by eight screws.

Once removed, you can access the optical drive and RAM. RAM access on the previous model was a bit simpler, only requiring the removal of three screws. Another internal change over the previous model is the optical drive, which is now SATA.

That holds out the potential for an aftermarket bracket for mounting an additional SATA hard drive in the place of a removed optical drive, for users who want extra storage more than access to optical discs. This upgrade is all about the physical design, but also offers a minor CPU performance bump over the MacBook Pros released earlier in the year.

The new 15" MacBook Pros use the 2. Only the 2. The 17" MacBook Pro, which has not yet adopted the new unibody construction, uses the same 2. There has certainly not been a massive increase in terms of clock speed over the last two years, but clock speed isn't everything; the last year of Penryn CPUs have also enabled additional CPU instructions including support for SSE4 multimedia acceleration.

The 17" MacBook Pro continues to have the same limitation because it also uses the same Intel controller chipset. The performance numbers presented by Primate Lab's Geekbench below indicate that the new MacBook Pro is not that much dramatically faster than the model it replaces, although it does inch closer to the existing iMac, even beating it in some respects. The new laptop certainly can't compare with a the Mac Pro desktop however.

Longer bars are better. According to NotebookCheck. Apple currently requires users to log out and back in again after selecting the "higher performance" graphics option that enables the switch to the dedicated GPU.

Mac OS X can do this within a few seconds, but it requires users to quit all their applications and save any open files, which can be a pain. Oddly enough, the Energy Saver interface doesn't make it very obvious that this is how you enable the faster GPU below top , although once you do, a sheet drops down to prompt you to log out and back in again below bottom. Graphical applications can't continue running while the window manager dies and restarts.

The second aspect of the semi-hidden GPU switch is that many users will likely never know to turn on the faster graphics potential of their system. Even those who do know of the difference will likely not switch between them frequently because of the extra step required, and instead either remain in the default, more efficient mode, or stay in higher performance mode and simply work mainly from their power adapter.

The difference between the two GPU options for normal desktop operations is unlikely to be visible. Users will notice the difference in playing games or when performing demanding graphics operations. It's the fastest integrated GPU currently available for notebooks, scoring around 3DMark06 points. It represents the lower end of graphics adapters for playing games; while modern games will run, most will require using limited detail and resolution settings.

The new chip is far faster than Apple's previous use of Intel integrated graphics, but the MacBook Pro never used integrated graphics. Now it has the option to, giving it a better battery life option with little decrease in performance over the former GPUs.

It represents the middle of graphics adapters for playing games; modern games should run with medium detail and resolution settings. The new notebooks ship with a new version of DVD Player: "5. They also provide a new build of QuickTime and Quicktime Player: both are still listed as version 7. As NVIDIA's new generation of controllers makes their way into other models, as is expected with the iMac next month, Apple's hardware optimization of QuickTime should provide a nice boost to a variety of applications that spend time on encoding, from iMovie to GarageBand.

This is not the case; QuickTime X is streamlined H. QuickTime has long supported the idea of adding hardware accelerated support components, but Apple simply hasn't taken full advantage of this because it has been moving between ATI, NVIDIA, and Intel graphics, making it difficult to standardize on built-in support for any specific technology.

With its increase share of the notebook business, Apple also now has more leverage to ask for NVIDIA's help in bringing support for custom features to the Mac. Another component of Snow Leopard, OpenCL, will help abstract the differences between different GPU architectures and make it easier for programmers to put more work on the GPU, which is quickly outpacing the CPU as the fastest engine in the computer. OpenCL may also be able to harness the power of both GPUs in the MacBook Pro to accelerate computationally intensive operations, but this potential has not yet been announced.

The new unibody MacBook Pro is much better built, more attractive, thinner, stronger and more rigid, with a nicer feel to the display lid and easier access to the disk and internals. It chooses a nice balance between weight and performance, using a smaller battery but compensating with greater overall efficiency to retain the same battery life as previous models. The glossy screen will not appeal to some users, but the display itself looks great, and is a significant jump up in quality compared to the smaller MacBook.

The new keyboard is great and the new trackpad offers some welcomed improvements, although it also presents some frustrating annoyances due to its differences. You'll have to get used to it. This model doesn't offer a major jump in performance in either the CPU or GPUs, but does give Mac users the first taste of GPU choice in terms of efficiency or performance, boosts overall speed a bit with a faster RAM architecture, and seems to run cooler and quieter overall than the previous MacBook Pros.

If you're in the market for a replacement MacBook Pro, the new model makes a great, well rounded upgrade. If you've recently bought a new MacBook Pro, the new model certainly won't blow you away in terms of greater performance. Compared to the 13" MacBook, the choice is pretty simple: a smaller and cheaper 13" unit losing FireWire, ExpressCard, faster graphics, and a better screen , or a considerably more expensive, larger, but compromise-free 15" model.

Here's what you need to do, and the best enclosures to get the job done. Here's what model you should buy based on how much you want to spend.

Here's how it compares to Apple's Intel-based Mac Pro tower, and why folks that rely on that machine may need to consider the laptop as a viable upgrade. Apple used the Razer Blade 15 Advanced as a point of comparison for the performance of the M1 Max chip. Here's how the rest of the notebook compares against the inch MacBook Pro.

Apple's new MacBook Pro range is powerful, but how does it compare against a gaming notebook? As Apple introduces its updated designs of MacBook Pro to the world, some other notebook producers are arguably moving in Apple-like ways. Apple shares 'Foundation' recap ahead of season finale. It was up to five times faster than the iBook and up to four times faster than the in. It featured a Because of its thinness, the MacBook Air was the first Mac to remove the optical Superdrive and feature a multitouch trackpad with gestures.

It included a in. LED display and a full-size, backlit keyboard along with a built-in iSight video camera. Apple later introduced an Apple refreshed its MacBook lineup with an aluminum unibody enclosure and a multitouch trackpad. This iteration of the MacBook was the best selling MacBook in history and the world's top-selling line of premium laptops. Apple also refreshed its white polycarbonate MacBook with a new unibody look. Apple first brought its notable high-resolution display from the iPhone over to its Mac lineup with the MacBook Pro with Retina Display.

This generation was also the first and last to feature an HDMI portalong with refined speakers and a thinner MagSafe 2 power port. Apple introduced a in. At just 2 pounds and only Retina display, a redesigned butterfly mechanism keyboard and a Force Touch trackpad. Along with a fanless design, the new MacBook was available in a slew of different colors to match the iPhone 6s and iPad Pro lineup — gold, silver, space gray, and later, rose gold.

Apple also unveiled upgraded in. Apple noted there were more online orders for the laptop than there has been for any previous MacBook Pro. Apple unveiled a revised MacBook Pro in July , with new Coffee Lake chips from Intel, including optional 8-core processors in the more expensive in.

Both the in. Pricing remains unchanged for the base models though the entry-level in. The in. It has a It runs on a dual-core I5 chip running at 1.
