    Didn’t plugging in an iPad or IPhone to power used to Wake a MacBook as well as initiate iTunes Sync? I ask because mine do not (I thought they did previously) and wonder if this is related to the sleep wake issue.

    I thought so. I’ve always found WiFi sync to be unreliable. I know I’ll have my iPad charging with my iMac on and it won’t sync for weeks. My phone has the same problem. Oddly the most reliable device to sync is on old iPhone 5C that I use as an iPod. It is also the device I care the least about backing up and syncing.

    I was under the impression that the two main attractions to the apple ecosystem were media syncing and the it just works mantra. I would think iTunes would be a priority, but I have long given up on expecting automatic syncing via wifi, among a number of other things. When I first rejoined the apple environment (Mavericks), I was kicking myself for staying on windows for so long. Now, I feel Apple has just continued to get consistently worse.

    The Mac needs to be awake to perform on demand tasks.

    I set mine to never sleep. And then let the screen and hard drives shut down when unused. But the actual cpu needs to be awake.

    If iTunes is open on the computer, and you checked the box to sync this phone over Wi-Fi in iTunes, then the syncing has been reliable for me with both an iPhone 5 and iPhone 7 since the last year of iTunes updates (prior to that, it was very problematic).

    Thanks.

    Yes, it will do it when awake. However, sync used to wake the mac over wifi (TV app still does). I do not want to 'never sleep' as I don't want my attached RAID to be on all of the time (been having wake/sleep issues possibly related to external RAID as well).

    Surely it can't automatically sync over wifi - it would be stuck in a continual sync...mine have always synced on demand over wifi and automatically when you connect via cable. I haven't noticed any change to that behaviour with 10.13.6 so far...

    Or am I misunderstanding the problem?

    “When the computer and the iOS device are on the same Wi-Fi network, the iOS device appears in iTunes. The iOS device syncs automatically whenever it charges and iTunes is open on the computer. Learn more about what you can sync and how to sync specific items.” https://support.apple.com/en-us/ht203075

    They still sync over WiFi automatically (and on demand as you mention) - if the Mac is awake when I plug the iPad into power. Previously, plugging in the iPad to power would wake the Mac, then sync would start.

    LOL - I don't think I've ever noticed that behaviour :)
