My iCloud Photos do not appear on my new Mac Mini

Hi!

Here to help!

A few inquiries:

• Apple ID: the same on all devices?
• in Photos App on Mac Mini: in Photos > Preferences > System Photo Library overview in Photos on Mac - Apple Support

and don't forget:

Turn on iCloud Photos

In the Photos app on your Mac, choose Photos > Settings, then click iCloud.

Select the iCloud Photos checkbox.

Select one of the following options: Download Originals to this Mac: Stores the full-size versions of your photos both on your Mac and in iCloud.

(System Library)

You should be able to see the progress in "all photos" - scroll all the way down.

Is there any trouble with the apple ID in system settings?

Let me know if you need more help!

Kind regards

Two thoughts on doing that...

A. Restore from a Backup:

If you backed up your Mac prior to updating it, then restore form the backup. Sometimes, the macOS can become corrupted due to major changes being made (i.e update installed or shutdowns). So, know to always back up your Mac prior to making any major changes to it, successfully as au update. In doing so, you with have something to restore store your Mac from from, should anything go wrong with the upgrade.

B. Reinstall the macOS anew:

You'd backup your Mac, install the previous macOS, and then migrate items back.

1. Create: a Time Machine Backup using an external Hard Drive
2. Install: from a USB Installer created for macOS 10.15 Catalina or before
3. Migrate: items from your TMB
4. Download then Install: the applications, getting the programs back from the Developer

"My iCloud Photos do not appear on my new Mac Mini: My iCloud Photos do not appear on my new Mac Mini. the Photos Library remains blank. Something is very wrong but I can't identify what. I have gone through all the articles and set up in the Photos Settings and the iCloud settings for photos suggestions in the forums to no avail. I can see all my pictures on my iPhone and iPad, but not my Mac. Brand new machine."
