Hello everyone I have some concerns related to battery replacement procedure on a macbook air. The thing is I brought my laptop to a place for a replacement and at some point the technician after replacing the he connected some kind of usb in it and then started the laptop and it loked like it was processing something, while asked what was that he said it was some kind of configuration... but I have some doubts about it. Any ideas on this? Was he doing something shady like stealing my computer information or is just part of the “procedure “?
Thanks in advance.
