New features to protect your Mac
The latest incremental update to macOS Big Sur 11.2.2 has introduced a feature that will help prevent damage to USB-C ports by third-party and non-compliant USB-C hubs and docks. Apple advises MacBook Pro from 2019 or newer and MacBook Air from 2020 or newer will benefit from this update. We urge users of older devices to only use USB-C devices from reputable vendors to prevent damage to their device.
Users can update to macOS Big Sur 11.2.2 by choosing System Preferences from the Apple menu , then clicking Software Update.
Since the introduction of the USC-C port many users have experienced issues with docks, hubs and cables causes their USB-C ports to break and in some cases completely brick their device. Industry leading micro-solderer Federico Cerva of Logic Board Repair London is finding more and more cases of damaged USB-C ports, "We have seen an influx of MacBooks with blown USB-C ports, most commonly stemming from users plugging in third party cables or adapters made by no-name brands purchased from Amazon or eBay. Whilst the devices can be repaired by companies who are familiar with micro soldering approaching Apple direct will likely result in a very costly logic board replacement. It is best to spend a little more in order to get a good quality USB-C accessory than try to save a little by buying the cheapest, it could save you a costly repair bill".

What to do if a USB-C port is damaged
Users that have a USB-C port damaged by a third party adapter have two options. The first is to book the device in for repair with Apple, this can be slow and will likely be a costly proposition as usually the whole logic board will be replaced, prices for this can range from £500-800. The second option is having a component level repair carried out by a reputable micro soldering firm such as Logic Board Repair London where a typical USB-C port fix is £299 + VAT.
