Although iCloud, MacOS, and Photos (formerly iPhoto) are older and should be fairly bug-free, a ghost runs through your code which sometimes causes photos to just not sync correctly between devices. It happens to me –and it despairs me– when I go back home, home wifi, with the camera and import the images into Photos and at the same time I have taken some new photos on the iPhone. The result is usually that although if you enter via the web in iCloud the new photographs appear, instead the Photos application remains toast and it shows nothing new. Sometimes for days.
After years of reading possible solutions that no they work or sometimes they work and sometimes they don’t (I’m not the only one: the Apple support forum and those of experts They have been with the same for years), here is the best remedy I have found, followed by other possible remedies that sometimes work sometimes not:
Kill Photo-related ghost processes
The solution is to “kill” (kill) various processes related to the Photos application that are always running in the background on MacOS, including indexing the metadata of photos, recognizing faces and objects, synchronizing images, and so on. Something causes one of them to get stuck and although it is not very clear which-does-what “Kill” all of them this solution is harmless and allows you to restart them … which reactivates the synchronization. It is done like this:
- Open the Activity Monitor (Command + Space activity monitor.app).
- In the search box, type photo to filter all the processes related to the Photos app.
- Select all processes (Command + A) from the list.
- Click on the icon Stop and choose Force exit.
And problem fixed.
Try “off and on” (various versions)
The universal solution to technical problems of any kind is also applicable here and sometimes it works. The various variants are:
- Disconnect from iCloud / Apple and reconnect, in MacOS> System Preferences> Overview> Sign out.
- Disconnect from iCloud in Photos and reconnect, in the Photos application> Preferences> iCloud> Photos in iCloud. Note that this can take a long time if you have a lot of photos because it starts to review everything.
- Repair Photos app starting it while pressing the Option + Command keys. This also takes a while.
Lucky!
