Syncing of iPhone 7 to iMac (Safari)

Thanks turingtest2. Yeah I had done that previously. Yet I went back again and check over both iPhone and iMac. iPhone 7 was my primary only Apple product until I bought iMac last year. It worked great until Catalina. I'm learning lol. iPhone no issues. iMac if I download music or video's they show in Apple Music but will not play. Now they do show and play on my iPhone with out connection. I have to connect phone to iMac to complete download on iMac. That's my issue. Thinking maybe trying One download at a time on iMac, thinking it maybe a internet connectivity issue of overload. I tend to see one music item then choose others also. Thanks to you guys I feel confident it will get resolved. Thanks again !

You're right Safari has nothing to do with. Catalina was the name I was looking for. I've gone through all those procedures to sync my Music with devices. My issue is I can only sync my Music if I plug in my phone to iMac. Does not transfer music downloads. Everything else it sync's. Looking for solutions. Thank you.

I can download music to my iPhone but not seeing it on my iMac unless I connect phone to iMac. I’ve sync them by instructions. Auto downloads on each etc. If I download a music video on iMac

it want work until I connect iPhone to iMac. I realize it maybe WiFi issue but I’ve bumped my WiFi signal no change. Before Catalina it worked as advertised. I’m NOT a wizard, I’m learning. Advice or suggestions I welcome. Tks !

Yes Demo Apple Music. I’m signed on with both devices to same account. Worked find until Catalina. Now iPhone was my primary account until I bought iMac. No issues other than my familiarity with iMac. I added iMac to account and downloaded all previous music no problems. Now my pictures I get sync right on both devices. It’s music only, especially if I download from iMac. It loads on my phone but when I go to play on iMac it just turns blank. Once I connect iPhone and allow it to finish downloading to Mac no problems. Beats me ! At least I know connection to phone solves it. EVERYTHING it says to sync devices I’ve done over and over. I do appreciate your input, thanks.

Well as I’ve said I’m not a wizard, I’m subject to making mistakes as others. But as I understand it long as I have paired my iPhone to the iMac under same account then turn on device sharing this issue is a problem. For pictures I do not have to physically connect them, it works as advertised. Music I have to connect them to have synced downloads. E mail same as pictures, I delete from one it deletes from other. Only messaging not suppose to sync: I know this. Good luck in this environment getting anyone in chat or on a phone. Tks !

Yes I did reboot the modem and iMac, the speed did increase. The only reason I bought internet service was for the iMac, to handle security, Home stereo system, etc... But I discovered my cable system was taking enormous data causing larger than normal Bills from internet provider. I took it off internet WiFi. Using phone WiFi for it when needed, I.E. watching pay for view. iPhone WiFi is unlimited data and I live near a tower making phone signal strong. Of course phone stays with me so I couldn’t use for say home security because I’m not always home.

Yeah systems such as cable basically steal your internet data after paying those high price programs if you sign them to your home WiFi system. Matter of economic’s . I work from my phone most of the time, iMac is for my time.

Solved. but thanks for the Help. Solution switching to iPhone wifi instead of internet wifi.
