When i use coconut battery it says my mac is 4 weeks old and i have 13 battery load cycles.. is that alot? i mean a i seriously think a few days ago it was at like 7 cycles and now my battery efficency is at 99% as opposed to 100 it was a week ago, also when i got my mac it said 3 weeks old on coconut as well. Also as a side note not on topic is it safe to upgrade my HDD now with that whole EFI 1.7 thing or will i be fine.
