Question : addressbooksourcesync
I have a Mac book pro and for some months, my battery works 3 hours max... I used to work for more than 8 hours 6 months ago. Running Mac OS Sierra 10.12.4
I started system monitor and I saw a process called AddressBookSourceSync using more than 95% of processor and 2.6 gig of memory????
I tried to stop it but no way... It comes back always...
I suspect this process to use resources more than necessary...
Thanks a lot and have a nice day
