The Situation: MacBook (Pro or Air, no difference) can't makes first copy to Time Capsule disk if:
- Power Nap is switched on.
- Power cord is plugged on.
- Disk on Mac is SSD.
- I start copy via Time Machine, it starts normally.
- I close the lid, wait 10 minutes, open the lid and see that copy process fails.
If lid is open, copy process run normally.
The situation is true for number of laptops, 2015, 2016, Pro or Air. Always all software are updated.
Apple tech support (via phone and chat) told that it is recommended to not close the lid. If I ask "why, what prevents Power Nap to make the copy" no certain answers. Only, "we advise you". There are no certain article about this process.
Question: Why should the first copy be done with lid opened (not put to sleep)?
