According to a report from MacRumors, it appears that for the 2018 MacBook Pro, Apple has removed the data recovery connector from the logic board to make way for T2 chip. For those unfamiliar, the data recovery connector was what allowed Genius Bars and Apple Authorized Service Providers to recover data from the non-removable SSD via a special tool.
However now that the connector has been removed, it seems that there is now no way of recovering the data stored on the laptop, at least not via traditional methods, according to multiple sources of MacRumors. It is possible that maybe Apple has another way, but if they do the internal document for its Customer Data Migration Tool has yet to be updated to reflect that.
This does not mean that your data will be lost forever in the event that your laptop stops working. Instead Apple’s Service Readiness Guide recommends that customers can consult with various data recovery specialists who might be able to help. In the meantime if you do own the 2018 MacBook Pro, like we said, perhaps backing up your data every so often is a good way to minimize your risk.
