Photos on iphone are no longer moving to my imac

Verify your iCloud settings on both your iPhone and also your iMac. Make sure they are still setup to sync and that you have adequate space in your account. If you don't have enough space, then you will need to buy more space or manage the space you have a little better to suit your needs.

I added 2 TB iCloud space to provide adequate space for 187 GB of iPhone Photos to be uploaded to my iMac. I can't get my iPhone 13 Pro Max to upload to my iMac. I have tried time and time again. Please help.
