Can Find My Mac still persist after...?

Hello all,

I have recently acquired a macbook air 2011 off of ebay. In order to avoid second-hand mac issues relating to icloud remote shut downs, I have performed the following actions:

-Secure erase (using parted magic), deleted old partition and created a new partition (using gparted).
-Cleared PRAM/NVRAM using keyboard procedure a few times, after HD was already wiped.
-Installed Ubuntu (I will be using Ubuntu, and Windows through VB).

My question is if there is any way that Find My Mac capabilities could have persisted, and would it be able to shut me down if I connect the macbook to the internet and the seller (or sellers seller) decides to lock the device on icloud?.


Thanks,

Jenna Boner

Any other info you need I'll be glad to provide.

P.S.:I guess it can be asssumed that the device did not have a firmware password, or such capability was not active at the time, since I was able to plug in a USB and load parted magic.

I have posted this inquiry on hackmac as well, but thought it would be helpful to get an even more specialized opinion on the matter. Thanks again for your time and for everything ya'll do for the community.

yes, not possible. Happy days.
