I am using an iPhone 6SE. After the last security update for BigSur OS, I don't see any way to sync my phone with my computer.

Thank you. I did find that location, but my phone has been connected for hours and it still shows the software is loading. I have read about the USB vs Wifi syncing, but until my phone software is loaded into the finder, I really can't do anything. I have set the auto-lock to Never, and will let the computer and the phone connected to see if that can speed things up, so I can change the settings to WiFi syncing.

Thanks, I am connected with a cable to the iMac. Phone is in the finder now, with the never put to sleep option turned on. The computer is on, and it says Software: Loading. That is as far as it has gotten... still waiting... Both the iPhone and my iMac are up to date on the latest OS. I had this issue since I upgraded to Big Sur, but did sync through iTunes (or Music), but that option is no longer available with the latest security update...

Thanks. This was to backup my iPhone, and sync basically podcasts, pictures, emails and messages. I had the settings in the phone set to sync over wifi while charging, and that worked really well. Photos, text messages have not been syncing properly since I updated the iMac to Big Sur, particularly after the last security update. It's been over 3 hours, and my screen still says my Software: Loading, but I can't find a way to monitor if anything is happening. The phone was disconnected without any warning of interrupting some process. My phone is currently running OS14.4.2...

Thank you! I rebooted the phone and reset the auto lock on the phone for "never" so there would be no interruptions while the phone was being recognized by the computer. I used the cable after I booted up the computer this morning, and everything went quickly and smoothly. Much appreciated!
