Most Mac power supply issues stem from problems with the power port or cable, so we'd advise trying to use a different cable to start with. If you are still having issues, book a diagnostic with our experts and we'll check your device and provide a new power supply if necessary.
If your Mac is crashing, not turning on, or not allowing devices to connect, this could be a logic board issue. We'll perform a diagnostic and if necessary send your device to one of our specialist partners to fix the logic board. Alternatively, if it is heavily damaged, we may need to replace the whole part. We will repair your device for the lowest cost and adjust your quote if necessary.
