Mac Book Firmware Updates

Firmware is the name given to software that is written into memory circuits such as flash memory, that will hold the software code indefinitely, even when power is removed from the hardware. Firmware on Intel Mac computers is designed to be updated if necessary through a software update. EFI and SMC firmware is stored on the MacBook logic board. EFI firmware updates update the Boot ROM, and SMC Updates update the System Management Controller firmware. The SMC manages fans and other environmental parameters that are independent of the Boot ROM. Firmware symptoms can be easily mistaken for hardware issues (e.g. overheating issues, fan noise issues, etc.). Always check both EFI and SMC firmware versions and update if necessary before replacing any hardware components in the MacBook Pro. The following lists describe the type of symptoms that may be resolved by updating the EFI and SMC firmware in the MacBook.

Mac Book Air W Mag Safe Power Adapter Compatibility

The MacBook Air 45W MagSafe Power Adapter is specially designed to work with the MacBook Air. It has a low-profile, right-angled MagSafe connector to fit in the slim area under the bottom case while the unit is resting on a hard, flat surface. Although a 60W or 85W MagSafe adapter from a MacBook or MacBook Pro can provide adequate power to operate and charge MacBook Air, these adapters are not recommended because the connector does not share the same design to stay seated properly in the MacBook Air MagSafe port. Likewise, don't use the MacBook Air 45W MagSafe Power Adapter to operate or charge existing MacBook and MacBook Pro computers that require the 60W or 85W MagSafe Power Adapter. Always use the proper power adapter intended for use with each product.

New Parts and Procedures

Macbook Pro Intel Duo 2006 Selfrepair

The MacBook Pro (15-inch Core 2 Duo) not only hosts the Intel Core 2 Duo microprocessor chip, but it also reincorporates the popular 9-pin FireWire 800 port from the PowerBook series. Note that the additional port makes this bottom case incompatible with previous the MacBook Pro. Like the MacBook, the MacBook Pro (Core 2 Duo) now utilizes JST wire bundle connectors that disengage by lifting up and pulling the connector out of its mating part on the logic board. Just snap the connector back in.The fans, thermal sensors, and back battery all use this connector. The keyboard backlighting has been improved. In addition, the programming of the caps lock key was changed to fix a developer keyboard mapping issue. Thus, this keyboard cannot be used in previous MacBook Pro 15-inch systems. The caps lock key will not be recognized. With the MacBook Pro (15-inch Core 2 Duo), we have brought back the whole display clamshell as a service part. However, unlike the 17-inch Core 2 Duo, we offers some...

Power Issues Power Adapter Dead No Power

See Knowledge Base document 303319, Resetting MacBook Pro Power Management Unit (PMU) When you focus on the MLB, from the block diagram, you can see that the MacBook (13-inch) AirPort Extreme Card is on the PCI Express bus. Investigate other devices on the PCI Express bus, such as the Ethernet controller. Determine if the Ethernet port is working. (System Profiler is a good tool to verify I O.)

Resetting the System Management Controller SMC

If the MacBook Air is on, turn it off. 4. Wait 5 seconds and press the power button to start the MacBook Air. Caution Reset the SMC only when the MacBook Air has been properly shut down. This prevents file system corruption. While the power adapter does not need to be connected to reset the SMC, it may be necessary in situations where the battery needs charging, or the MacBook Air has been without power for an extended period of time.

Warning Do NOT allow the logic board to flex at any time Flexing the board can crack solder joints to components Give

Important In the MacBook Pro (17-inch Core 2 Duo) only, there are two metal shims on the under side of the logic board near the graphics chip (see callouts below). If reusing this logic board, make sure those shims retain their position above the heat sink posts. 1. Disconnect the ten cables shown. (Note some of the cable connectors in the MacBook Pro (17-inch Core 2 Duo) may be JST connectors, not pictured below.)

Software Sluggish Due to Excessive Warmth

Software (especially video games or other graphics-intensive software) may operate sluggishly when the MacBook Air is very warm. This is expected behavior. MacBook Air uses built-in graphics circuitry to provide video output to the built-in and or external displays. The operating system automatically reduces the processor speed if the computer starts to get too hot. This will correspondingly reduce the graphics performance of all running applications. Refer to Knowledge Base article 307297 MacBook Air 3D Graphics applications less responsive when CPU is hot

Application quits Kernel Panic or other startup problems

When you focus on the MLB, from the block diagram, you can see that the MacBook (13-inch) AirPort Extreme Card is on the PCI Express bus. Investigate other devices on the PCI Express bus, such as the Ethernet controller. Determine if the Ethernet port is working. (System Profiler is a good tool to verify I O.)

Sharing Discs with Remote Disc

You can enable DVD or CD sharing on a networked Mac or Windows computer using the Remote Disc feature, allowing the MacBook Air to share the discs you insert into the optical disc drive of the other computer. Some discs, such as DVD movies and game discs, may be copy-protected and therefore unusable through Remote Disc.

Keyboard

Both 17-inch MacBook Pro keyboards utilize flex cables that are incompatible with previous PowerBook G4 keyboards. Also, this flex cable difference renders the 15-inch MacBook Pro keyboard incompatible with either 17-inch MacBook Pro model. The MacBook Pro (17-inch Core 2 Duo) keyboard backlighting has been improved over the MacBook Pro (17-inch) model. In addition, the programming of the caps lock key was changed to fix a developer keyboard mapping issue, and thus cannot be used in the previous MacBook Pro (17-inch) or the caps lock key will not be recognized.

Overview

The MacBook Pro (17-inch), MacBook Pro (17-inch Core 2 Duo), and MacBook Pro (17-inch 2.4 2.2GHz) represent three generations of the MacBook Pro professional notebooks. The original MacBook Pro (17-inch) is based on the Intel Core Duo chip, while the latter two MacBook Pros (17-inch Core 2 Duo and 17-inch 2.4 2.2GHz) are based upon two successive iterations of the more recent Intel Core 2 Duo chip, with the latest increasing processor speeds from 2.33GHz to 2.4GHz. The newest MacBook Pro (2.4 2.2GHz) supercedes the previous MacBook Pro (17-inch) models in four ways the bus speed has increased to 800MHz, the system now addresses up to 4 GBs of RAM, it sports a new NVIDIA GeForce 8600M GT graphics chip, and can come configured-to-order with a higher resolution 1900 x 1200 (antiglare or glossy) display. The only outwardly visible difference between the three machines is a small opening in the display bezel for the LED to the right of the iSight camera in the original MacBook Pro...

Identifying Feature

There are no recognizable visual differences between the MacBook (13-inch Late 2007) and MacBook (13-inch Early 2008) models. To distinguish these models from the previous MacBook model, refer to the shape of the vents on the back of the computer. The Late 2007 model and Early 2008 model have five long horizontal vents on the bottom case under the display clutch cover. MacBook (13-inch Late 2007) and (13-inch Early 2008) Conversely, the previous MacBook model had multiple short vertical vents on the bottom case under the display clutch cover. Previous Model, MacBook (13-inch Mid 2007)

Air Port Extreme

The MacBook Pro (17-inch Core 2 Duo and 2.4GHz) utilize an AirPort Extreme card with a three-wire 802.11g antenna. The length of each wire and its color will help distinguish which wires go to which terminals on the card (black longest left, gray medium middle, blue shortest right). The MacBook Pro (17-inch) uses the same AirPort Extreme card as the 15-inch MacBook Pro and does not support Bluetooth. It is the same form factor used in the iMac (Early 2006). However, there are two version of these cards, and they are not interchangeable. The AirPort antenna for all 17-inch MacBook Pro models is located in the clutch barrel underneath the gray plastic window.

Main Memory

The memory connector is a stacked memory design. The MacBook Pro (17-inch) supports up to 2GB of RAM, and the MacBook Pro (17-inch Core 2 Duo) supports up to 3GB. However, note that in the latter, while you will have a perfectly bootable system with two (2) 2GB RAM modules See MacBook Pro (Core 2 Duo) Memory Specifications for more information. Main Battery Both MacBook Pro 17-inch models use battery packs built with the same lithium polymer battery technology used in our iPod product line, though the basic chemistry is no different than previous lithium ion cells. An unchanged battery controller keeps the battery calibration procedure the same as it has been since the PowerBook G4 line.

Main Logic Board

The original MacBook Pro (17-inch) is based on the Intel Core Duo chip, while the latter two MacBook Pros (17-inch Core 2 Duo and 17-inch 2.4 2.2GHz) are based upon two successive iterations of the more recent Intel Core 2 Duo chip, with the latest increasing processor speeds from 2.33GHz to 2.4GHz. The boot architecture of the MacBook Pro is based on Extensible Firmware Interface (EFI), replacing Open Firmware (OF) of PowerBook G4 days. Boot snag keys such as C for boot from the optical drive, N for network boot, and T for Target Disk Mode stay the same under EFI. To launch Apple Hardware Test (AHT) from the Mac OS X Install disc, you must hold down the D key during boot.

Express Card

ExpressCard has replaced the PCMCIA card cage in the PowerBook G4. The ExpressCard standard supports two sizes cards, 34mm and 54mm width. MacBook Pro supports the 34mm standard. Unlike the previous PCMCIA design, there is no eject button. The card itself is used to engage and disengaged itself from the card cage. In some designs like Ethernet ExpressCard, the card sticks out beyond the card cage. It is easy to push on the card to release it. Other cards will be flush with the MacBook Pro enclosure and will take a little more care to pop out.

Universal binary

An application so it runs natively on either a PowerPC-based or Intel-based Mac. This application can run on older systems and the new MacBook. A Universal binary application works directly with the Core 2 Duo microprocessor. As discussed in the following section, older non-native PowerPC applications can still run on a MacBook, but will require a Mac OS X technology called Rosetta to translate for the Core 2 Duo processor. Note The Classic (Mac OS 9) application will not run on MacBook. Recommend to customers that they upgrade to Mac OS X versions of required applications.

Speakers

All 17-inch MacBook Pro models sport four speakers with two separate speaker modules (left and right), each with two speakers each. Since the system can output a lot of sound, it is very important to make sure screws are properly tightened down. As a mobile product, a loose screw can eventually work itself free, and using the speakers at elevated volumes can also work toward loosening a screw that is not properly installed.

Part Number 922-8025

Mac Pro Back Panel

Important As you start to unscrew each short screw, look directly below the cage for the screw's standoff. If the standoff starts to turn as you turn the screwdriver, use the Apple Mac Pro wrench (part number 922-8025) to hold the standoff in place while you turn the screw. Insert the Apple Mac Pro wrench (part number 922-8025) around the hex standoff located directly below the stripped screw, as illustrated. Turn the wrench to separate the hex standoff from the enclosure. If both screws are stripped, alternate turning the wrench between the two standoffs so that the memory cage rises evenly.

Screw Maps

Because of the MacBook Air's contoured shape, many components use screws of multiple size and length. Replacing even identically-sized screws in their original locations, especially on the bottom case, ensures the easiest and most intact reassembly. The screw maps on the following pages (thumbnails below) can be printed on magnetic-backed inkjet paper to allow for precise screw storage and reference during take-apart procedures. (All screws in the MacBook Air contain ferrous material and should adhere to magnetic material.)
