Ok, so heres the thing. My new i7 mini mac arrived today, set it all up, seemed fine except connecting to wireless keyboard. Overcome this and done a restore from time machine backup (late 2012 macbook air) but everything seems really laggy. Keep getting spinning wheel everytime i try to open anything from finder to safari to photoshop. My question is, should it make a difference where the time machine back up came from ie from MBA to Mini Mac.
