i currently traded in an old macbook and gave my mom my imac. I bought a new mac pro but there is an issue with find my mac. i disabled find my mac on the imac and the macbook was wiped by bestbuy. however, both computers still show up on my find my mac app. it's not a huge deal but it's just annoying seeing 2 devices in there that will never actually be found. any ideas on what to do?
I have seen some reports of this too. I'm not at all certain whether the 'Find my mac' feature gets written to firmware in some cases, in which case it would require a PRAM reset, which unfortunately can't be done without access to the computer.
