Apple is claiming 450 mb data rates because in a 40mhz channel 5ghz situation, they can use a 3rd spatial stream. It's way more repairable and upgradeable than its sleeker-looking sibling. While its sibling with the Retina display may have stolen all the press, this MacBook Pro is nothing to scoff at. We just couldn't stop after digging in to the MacBook Pro with Retina Display and the MacBook Air, so we got our hands on the Mid 2012 MacBook Pro. Most laptops are 2 spatial stream (Max at 150mb data rate on 2.4ghz, or 300mb on 5ghz (when 40mhz wide channels are enabled). We've had a busy week since Apple announced its new products at WWDC on June 11, 2012. Mobile phones with 802.11n today are usually 1 spatial stream and 1 antenna (Which is why they max at a 65mbps data rate). Aruba APs are mostly 3x3:2 (3 antennas, 3 transmit chains, but still only 2 spatial streams). In fact, most Cisco APs are 3x2:2 (3 antennas, 2 transmit chains, 2 spatial streams).

It does not have an "Extra" antenna for 802.11, that J3 antenna is hooked into the BCM2070 Bluetooth chip at the bottom of that wireless board, so it's a bluetooth antenna.Īpple is still ahead of the game with a 3x3:3 radio, as most APs (Even Cisco enterprise APs) do not support 3 spatial streams today. There could be more clarity around the wireless card.

I understand that as delivered, the motherboard is designed to work with an optical drive on the optical drive port (3gb/s) & a SSD or HDD on the main 6gb port.ġ) Where's the actual quote of what David Moody said?ģ) Given that he is a hardware executive, is it reasonable that they did a hardware correction, (rather than a software patch)Ĥ) Can we trust that Intel's budget for the recall replaces for full HDD support on the optical drive Cleaver.

: "Earlier this year, Intel discovered problems in the chipset of Sandy Bridge processors that were shipping, but Apple vice president of worldwide Mac hardware marketing David Moody told Macworld that the company was using the latest updated versions, which corrected the flaw."įrom. So I did some digging - the best assurance I can find is on. That link shows people have already fitted exiting OptiBay models.
they've emailed to say they will know within a few days their official opinions. I've an outstanding request with MCE Technologies asking them to verify. I suppose that shifting the SSD to the OptiBay and adding a HDD would necessitate changing a PRAM / NVRAM setting. The drive is considered user replaceable - such that users can swap either HDD for SSD or (less likely) SSD for HDD - meaning the motherboards must be identical and include the Sudden Motion Sensor. My conclusion / assumption on this is that the SSD models are all build-to-order vs, ready made for the HDDs. That said, I couldn't see a KXM chip on the teardown photos (but didn't find them on past models either.) , the MacBook Pro has in the past featured a Kionix three-axis accelerometer chip, (KXM52-1050), for protecting its HDD. In the end, you have to take into account that old phrase of not judging by appearances, since these teams are much more than what meets the eye.According to. The conclusion of iFixit and that we also share in this writing, is that in the end these apparent changes are small, but enough to see a sample of the fine work that Apple has been doing in these years and that in the future it will be seen more abruptly. To this must be added the security T2 chip that in this case is directly integrated into the M1. Something curious and that does not seem to have liked too much is that the integrated memory ( RAM) is difficult to repair without official Apple tools. Of course, this does not mean that for this reason the ventilation problems seen in previous generations are still present, since in the end the processor is totally different and it is already seeing a much better optimization than those that were with the Intel. The cooling design of the computer, including fans, is identical to the previous model.
From the MacBook Pro it is recognized how complicated it was to differentiate it from the model with Intel, since in this team there are many more similarities than in the case of the ‘Air’.
