Why is Mac sync to iPhone so damn bad and so damn slow!

I have been syncing my mac to the iphone since the iphone first came out, and the problem is that it has never gotten better. I sync a bunch of live music that isn’t available on streaming, so I sync to my computer Iplus it means my phone is backed up with passwords so if I restore I get my full working phone, which people on iCloud do not, they have to re-enter all passwords), but the actual sync is so awful.

First off unless you turn cellular, wifi and bluetooth off, the sync takes forever, but if you turn it off it is very quick, we are talking muti-hour sync vs 30 minute sync so it is huge. Why can’t apple fix this? Obviously they don’t care at all.

I hate having to do workarounds, but syncing my iphone with my mac via lightning cable means I have to switch my phone to airplane mode and that is fucking bullshit! If Airplane mode fixes the issue, then Apple could easily fix it, and they don’t care, as they do not want you to backup locally or put your own music on your iPhone.
