com.apple.photos.videoconversionservice

Does pausing the upload to iCloud not stop the process.

I have same issues you describe but my MBP has been running since April - right about a month to upload to iCloud? - Does not seem right. Right if you kill it Activity monitor it comes back to life later. To actually stop it I believe this is the "solution": Open Photos on your MBP, in top menu Photos > Preferences > iCloud tab - click "Pause for one day".

I am having same issues and been to several of these boards but can't find an answer.

In that Preferences area I bounce between "Adding 66 items" to "Uploading 22,000" items:

My CPU's frequently go above 300% - pic below:

If go directly to iCloud on the web and click "Photos" I see message about ~9,000 photos but get spinning wheel and error - which asks me to send report to Apple which I have done. Below is some info from that report - whether it has anything to do upload from Mac to iCloud or just the ability to view pics on iCloud I don't know.

My question is what does the process com.apple.photos.VideoConversionService actually do aside from doing 180% CPU time and heating up my MAC Book Pro when the MAC is idle ?

It is loading pictures from the computer to iCloud.

Thanks for the confirmation. It appears iCloud processes are causing most of the Macbook Pro performance issues.

In other forums I have read "com.apple.photos.videoconversionservice' is converting any videos to formats that would work on all Apple devices. I am not sure about that or even what that would encompass. Even if that were true it is taking an exorbitant / insane amount of time.

This fixed the problem for me:

Go to photos app; Photos dropdown, Preferences, select the iCloud tab, deselect all the check boxes in this tab. (fixing the problem may not require deselecting all of these boxes.)

I dont have any of those boxes checked - Photos >Preferences >iCloud - no boxes check yet this service is taking up about 80% of my CPU - any ideas?

I found that unchecking the Photos setting in preferences>icloud> photos, then selecting the Options buttons and checking only "My Photo Stream" (to allow automatic uploads from my phone to my mac), seemed to make the cpu revving go away.

It changes the "Photos" entry from a check to a "-", which I guess indicates a subset selection.

I have tons of photos and apparently the program to sync them with the cloud is not very efficient. Its not worth the slowness and risk to the processors overheating. This program should work in idle times only and with a maximum of cpu % taken, if I were to make any suggestions to apple about it, plus some indicator of progress so that you dont think its just some runaway process.

Many thanks - I had changed FROM this option yesterday and thats when the problems started. Reverting to the setting you suggested solved the problem. Silence at last and a faster MB Air
