As predicted, the proprietary locking system Apple rolled out with its 2018 MacBook Pros is hurting independent repair stores, refurbishers, and electronics recyclers. A combination of secure software locks, diagnostic requirements, and Apple’s new T2 security chip are making it hard to breathe new life into old MacBook Pros that have been recycled but could be easily repaired and used for years were it not for these locks.

It’s a problem that highlights Apple’s combative attitude towards the secondhand market and the need for national right to repair legislation.
