It would be fine if you could have 6-8 of those universal ports in those machine so there were plenty of holes to go around - but that's far more expensive and complex than adding dedicated ports for the most common requirements. Plug a charger in and you can't use that port for data or video, plug a display adapter in and you can't use it for video and data. This is the problem with the whole USB-C concept: one port for all sounds cool, but it actually means funnelling several scarce but unrelated resources: PCIe/USB3, video streams and power input/output - through a single connector and creating an artificial bottleneck. Yes - you could carry a multiport dongle, but now you don't need to - and if you are prepared to carry a hub around you can now use a TB4 hub that gives you 4 extra TB ports, a bunch of USB 3 and still leaves two of the original built-in TB ports free. IS THERE AN SD CARD ADAPTER FOR MACBOOK PRO DISK DRIVES TVNow do the same with the new M1 Pro Macs - the charger goes into MagSafe, the TV goes into HDMI and you still have all 3 TB ports left. IS THERE AN SD CARD ADAPTER FOR MACBOOK PRO DISK DRIVES FULLAn extra full function TB4 port needs a huge amount of resources in comparison.Īlso: take an old 4-port Intel MBP, connect a charger, plug into a data projector or TV (a pretty common scenario) and count how many TB ports you have free for other things - 2. The SD slot just needs a USB 3.0, HDMI just needs a spare eDP 1.2 stream, and the MagSafe doesn't need any CPU resources whatsoever (maybe a USB 2or IIC or suchlike for control). There's no evidence of a 4th TB controller that has been stolen by the restored ports. according to Apple, the M1 Pro/Max chips have 3 Thunderbolt controllers. So the M1 Pro/Max machines actually have 50% more Thunderbolt bandwidth than the old 4-port Intel MBPs, and the ports now support the new TB4 hubs, so each of those 3 ports can now run a hub with 4 TB4 ports that can be used for TB/USB or DisplayPort. the old intel machines where each pair of ports shared the bandwidth of a single controller. When you click a link and make a purchase, we may receive a small payment, which helps us keep the site running.īut now we lost one TB3 port for a HDMI port that most will never use or at best use infrequently.Īh, yes, the mythical "stolen TB3 port".Įach TB/USB4 port on the new M1 machines now has its own, dedicated controller on the SoC, c.f.

Update: The SD card slot on the new MacBook Pros supports up to 250MB/s of data transfer with UHS-II SD cards and up to 90MB/s with UHS-I SD cards, according to information shared by Apple after this story was published. Pricing starts at $1,999 for the 14-inch model and at $2,499 for the 16-inch model. The new MacBook Pro models have been available to order since Monday and will begin arriving to customers and launch in stores on Tuesday, October 26. In addition to the expanded connectivity, key features of the new MacBook Pro models include Apple's next-generation M1 Pro and M1 Max chips, mini-LED displays with ProMotion for up to a 120Hz refresh rate, up to 10 hours longer battery life per charge, full-size physical function keys instead of a Touch Bar, and more. The notebooks also have three Thunderbolt 4 ports and a 3.5mm headphone jack. The SD card slot is one of three ports that returned to the new MacBook Pro models after being removed in 2016, alongside an HDMI 2.0 port and MagSafe. IS THERE AN SD CARD ADAPTER FOR MACBOOK PRO DISK DRIVES PROFESSIONALThe return of the SD card slot will be particularly useful for professional users like photographers and video producers, allowing them to quickly transfer files without needing to use an adapter. Users can take advantage of the SD card slot for additional storage space, with UHS-II-compliant SD cards available in capacities such as 64GB, 128GB, and 256GB. Some people had hoped that the SD card slot would support UHS-III with read and write speeds up to 624 MB/s, but this is not the case. Apple has confirmed to The Verge's Dan Seifert that the SD card slot built into the new 14-inch and 16-inch MacBook Pro models supports UHS-II, and while this could theoretically allow for read and write speeds of up to 312MB/s with USH-II SD cards, Apple has since confirmed that the reader supports up to 250MB/s of data transfer. ![]()
