  • iFixit posts their Mac Pro teardown

    RtFlKRIVD1AnbWMo.mediumGadget teardown specialists, iFixit, have completed their full disassembly of the new Mac Pro and have given it an 8 out of 10 on the repairability scale. So what else did they find out? Best to head on over there for the full details (24 steps for the full take-apart), but here are a few of the juicy details (cherry-picked from the iFixit run-down);

    • it has taken some design pointers from the AirPort Extreme and Time Capsule bodies: a thin, vertical design with individual boards on separate sides.
    • simply sliding the lock switch allows us to remove the outer casing of the Mac Pro. No stubborn pentalobe screws here!
    • The RAM in the Mac Pro Late 2013 is easily accessible and replaceable.
    • it is vented by a single fan, which pulls air from under the case, through the core, and out the top of the case.
    • it utilizes a giant triangular heat sink (“Thermal Core”), shared by the dual graphics cards and CPU.
    • the new graphics cards may be the key to Apple finally undercutting homebrew systems on a pure power basis.
    •  a CPU upgrade appears entirely possible.
    • The power supply has no dedicated cooling, and relies on the main system fan to keep cool—allowing the Mac Pro to idle at a whisper-quiet 12 dBA.
    • Non-proprietary Torx screws are used throughout, and several components can be replaced independently.

    In spite of the lack of internal, user-upgradeable disk space, the new Mac Pro is a far cry from the iMac which has gotten more and more difficult to do at-home repairs or upgrades upon. Here’s hoping that Apple plans to offer some internal component upgrade paths.

  • iFixit completes 21.5-inch iMac teardown, discovers new hardware, lower repairability factor

    The new Apple hardware is out, and as is custom, the cool cats at iFixit have dissected it.

    In its latest teardown report, repair firm iFixit gave the 21.5-inch iMac a “repairability score” of three out of a possible ten, citing a hard to replace display and lack of easily-upgradable RAM, while the Online Apple Store sees ship-by dates pushed back to over a week.

    After the iMac rolled out to customers worldwide on Friday, iFixit took an in-depth look at Apple’s redesigned all-in-one and found the unit to be “an exercise in disappointment” as far as repairability is concerned.

    The firm’s first major complaint was the new display that is now glued to the iMac’s chassis rather than being attached by screws and covered by a removable magnetic front glass, as is the case with legacy models. While the screen is the identical to the one used last year, Apple used a lamination process to bond the front glass to the display, allowing less reflectance and deeper color saturation, though the strategy only allows for the use of glue to attach it to the computer’s thin body.

    Second on the list of complaints is the lack of upgradability. While users can change or replace the hard drive, RAM and CPU, they will have to remove the screen and logic board to do so as all integral components are located on the back side of the board. It should be noted that in its review of the 27-inch version, CNET mentioned that the larger-screened machine has an access port for RAM replacement.

    There was some good news, however, as the redesigned iMac now uses dual-microphone technology for better FaceTime call audio, as well as a more robust ribbon cable for the built-in camera. Also of note is that the large central heat sink, which only uses a single fan to keep internal temperatures within operational limits, is attached to a spring-loaded Intel socket carrying the CPU, meaning the processor is somewhat easy to replace.

    Less than a day after brick-and-mortar Apple Stores and authorized resellers started sales of the 21.5-inch iMac, the standard 21.5-inch iMac is shows a lead time of seven to ten business days, up from the one to three days quoted when the company activated orders through its online storefront late Friday.

    The apparent supply shortage for the smaller iMac echoes the soon-to-be-released 27-inch model, which is experiencing similar delays as orders are now expected to to go out in three weeks to a month.

    CEO Tim Cook warned during Apple’s quarterly conference call in October that thee would be a significant supply shortage for all iMac models, however the specific reason for this remains unknown.

    Stay tuned for additional details and if you’ve gotten your mitts on a brand new iMac, please let us know what you make of it in the comments.
