Anyone know the reason? Maybe to do with connecting to a network Time Machine drive? Noticed it when debugging why a Find My Mac kept the MacBook Pro awake, very hot in a bag, and drained the battery to 60%.

Hi,

same here, using a 2015 MBA. Found out couple of days ago..

Setup:

Synology ds215+

Samba min: v2

samba max: v3

only appears with tm-backup to synology. might be an issue with the nas itself?

also, it's dead slow....

keep you posted...

cheers,

m
