The third-generation MacBook Pro was released in 2012: the 15-inch in June, a 13-inch model in October. Updates brought Intel Core i5 and i7 processors and introduced Intel's Thunderbolt. Called the "unibody" model because its case was machined from a single piece of aluminum, it had a thinner flush display, a redesigned trackpad whose entire surface consisted of a single clickable button, and a redesigned keyboard. The second-generation model debuted in October 2008 in 13- and 15-inch variants, with a 17-inch variant added in January 2009. Later revisions added Intel Core 2 Duo processors and LED-backlit displays. The 15-inch model was introduced in January 2006 the 17-inch model in April. The first-generation MacBook Pro used the design of the PowerBook G4, but replaced the PowerPC G4 chips with Intel Core processors, added a webcam, and introduced the MagSafe power connector. All models from the current lineup use variants of the Apple-designed M1 system on a chip. It is the higher-end model of the MacBook family, sitting above the consumer-focused MacBook Air, and is currently sold with 13-inch, 14-inch, and 16-inch screens. 2012 Retina Macbook Pro - 80MB/s using UHS-1 SD card ( eview/13 ).The MacBook Pro is a line of Macintosh notebook computers introduced in January 2006 by Apple Inc.This would make sense then that the SD card is connected to a USB 2.0 bus indeed ( ). 2012 Macbook Air SD card performance appears to be capped at 40MB/s.2012 Macbook Air - shows SD card slot connected to USB 2.0 bus in System Profiler.2013 Macbook Air - shows SD card slot connected to USB 3.0 bus in System Profiler.I haven't been able to find any definitive source though that says that the Macbook Air SD card reader uses USB, while the Pro uses PCI-E. I'm going to guess that the Apple article ( ) lists "new Macs" as using the PCI-E bus when they should've specified "new MacBook Pros" and maybe iMacs. That’s slower than transferring to USB 3 external hard drive (copying the same file took around 40 seconds) Copying a ~600Mb file took right around one minute. Real-life testing gets about 10MB/second transfer speeds.

Transfer speeds will also depend on the mac as older MacBooks treat the SD card slot as a USB 2.0 connection, while newer ones use the PCIe bus to connect to the SD card slot.
Computers that use the PCIe bus express their speed as GT/s.Ĭlass 10 cards should get transfer speeds of at least 10MB/second, while cheaper microSD cards have as low as 4MB/second transfer speeds. Select Card Reader from the Hardware section (for Macs that use the PCIe bus to communicate with the SD card slot).Select Internal Memory Card Reader and look for the Speed entry.Select USB from the hardware section (for Macs that use the USB bus to communicate with the SD card slot).Choose About this Mac from the Apple () menu.Im also quite sure the OP was not using a FAST microSD card.last I recall you cant even find FAST microSD in retail electronics.ĭetermine the maximum speed of your Mac using the System Profiler: Newer Macs use the PCIe bus to communicate with the SD card slot and can transfer data at a much faster rate. You got the other info off Apple which states: Macs that use the USB bus to communicate with the SD card slot have a maximum speed of up to 480 Mbit/s. SD Card Readers in the current MacBook Pros are connected via pcie NOT however the current 2013 Air
