MacBook Pro 2021: the SD card reader of some computers is riddled with bugs

The 2021 MacBook Pros suffer from an SD card reader bug. According to a host of testimonials, the reader does not read certain cards correctly. Sometimes inserting a card even causes the device to crash. For others, transfers are terribly slow.

The MacBook Pro 2021, the new generation of high-end computers from Apple, have rich connectivity. On the slices, users have an HDMI port, a 3.5mm headphone jack, a MagSafe 3 port, three Thunderbolt 4 (USB-C) ports and an SD card reader. This ultra-complete connectivity contrasts with the brand’s previous models, which were content with a handful of USB-C ports.

According to numerous testimonies that have appeared on the web, this SD card reader is riddled with bugs. On Reddit, some Internet users assure that SD cards are not recognized by the MacBook or that the data transfer is much too slow. “I was trying to recover photos from SD card on my new 14 MBP ″, but when I inserted it into the SD card reader of the laptop it won’t connect”, explains a user, who specifies that not all SD cards are affected by this malfunction.

Some 2021 MacBook Pro’s SD drive is way too slow

In other, more extreme cases, MacBook Pro crashes completely when an SD card is inserted. For some, the Finder quits almost instantly without an explanation, leaving the user unable to transfer the files to the card. Finally, many buyers complain extremely slow transfers. “An SD card contains only 30 16 GB RAW files, and importing the files into Lightroom Classic takes more than 30 minutes”, regrets a user on the Apple support forum. Still, SD cards work very quickly on its old 2015 MacBook Pro, the testimonial points out.

It would obviously bea software issue inherent in macOS. Indeed, some users affected by the bugs claim that the installation of beta 4 of macOS 12.1 has helped to correct these dysfunctions. Deployed this Wednesday, December 1, the update could contain a fix for the SD card bug. Moreover, Apple has not yet publicly mentioned the existence of SD drive failures. Note that this is not the only malfunction spotted by buyers of a MacBook. The testimonials also point to bugs in the MagSafe charger, which blinks for no reason even when the computer is properly plugged in.
