Some Notes on iCloud library on a Mac

iCloud photo library is a great way to keep the libraries in sync across several Macs. Most of the changes made on a Mac will update on all Macs that also use iCloud photo library (we'll ignore for now iOS devices).

Exceptions to the rule: (use pictures and iCloud library on several Macs - Apple Support)

  • Projects does not synchronize: books, cards, calendars and slideshows
  • Thumbnails of faces doesn't sync, faces only available tags.
  • Not referenced photos download to iCloud photo library at all.

A library of Photos it takes on a volume formatted Mac OS extended (journaled), if you want to use iCloud photo library.  https://help.Apple.com/photos/Mac/1.0/?lang=en#/pht211de786

Not all media items can download on iCloud photo library. If the photo library has been upsized from iPhoto or Aperture, it can contain media, which are not compatible with iCloud photo library, for example some audio file format, or TIFF images high resolution. These will show as 'Local' only at the bottom of the display of Photos.

Because the version of your photo library iCloud can miss information compared to the local version, a library of Photos to iCloud recovery can be frozen. Always keep a good local backup.

Sometimes Photos will begin to download the complete library again to iCloud to compare it to the version of iCloud. This new download may take a very long time. For example, complete my library with 36000 necessary pictures a week to download it again.

A new download will occur after the following events:

Try to avoid these situations, if possible.  Photos's repeated outages can cause a repair of the library, but also issues permission, when you use the library of Photos from different user accounts.

Ahh, very useful information.  And show me how meet the requirement of 'Ask a Question' new specialties when there isn't a question at hand.  Thank you.

    If you disable iCloud photo library on your iPhone, you will see more pictures on this device. iCloud photo library on your Mac will still have pictures. You should not lose all the photos from your Mac, but make a copy of your library beforehand should put your mind at rest until you can verify that he has lost. Delete the pictures taken on your iPhone will not affect your Mac or iCloud, but neither future pictures taken on your iPhone will go into iCloud photo library.

    Try to go to iCloud.com to see if the elements are there and whether the device or the computer. That should indicate if the device or computer is not synchronizing. If the computer, try going to System Preferences/iCloud and stop synchronization. Wait a few minutes, then recheck the timing. If the device, go to settings/iCloud and do the foregoing.

  • WARNING: iCloud library deletes the original photos on Mac

    Recently, I turned on the library to iCloud in the Photos app preferences. I chose the option "Download this Mac originals," not "optimize Mac memory" so all my original full quality photos will remain on my Mac and probably be safe. After uploading to the cloud ended (took a while), I made a backup of my Mac using Retrospect. I noticed that a lot (almost all by the number of GB) photos were being backed up, what happens if the file or its attributes modified. I was wondering why to send photos to the cloud would change my photo files. I decided to review individual cases to see if there were differences from the original versions. (Luckily, I had a clone of my HD last week, which had all my photos some before iCloud photo library has been activated.) So I could compare the originals on the clone for the pictures changed on my Mac's hard drive.)

    To find files modified more easy, I used sync Pro, which gives me a list of files that it thinks are different. I discovered that more than 150 of my 9500 photos have been deleted after turning on iCloud photo library! It was shocking, but it is good news.

    I have carefully reviewed the photos maybe a decade or two that had been deleted. If they had any duplicates which were not deleted. In other words, apparently Photos, trying to send photos to iCloud, reviewed my photos and remove duplicates from my hard drive. By comparing these duplicates, I have found not all were an exact replica, as follows.

    • Several photos appear to be identical files with the same size and file modification dates. Actually duplicates, thus eliminating one is without real loss, although I don't like deletions of software that Apple all of my original photos at first.
    • Some 'duplicates' had different size files. It's relative. In all these cases, examine photos of GraphicConverter revealed that Photos had deleted the photo of lower quality, depending on the quality of compression ratio or %. (The photo of lower quality is not always a smaller file size.)
    • Some "double" had same file sizes but different modification dates. I think that, in these cases, pictures kept the old file, which would probably be the original.
    • Some have had different file size and date to change different.  In these cases the Photos deleted the photo of lower quality.

    Based on examination of a small percentage of the total number of deleted duplicates, Photos seem to be taken of intelligent decisions on how to remove duplicate.

    What I don't know, is how or why most photo changed during the download process to iCloud, such files as revealed by Retrospect. But looking at my photos, I did not notice any obvious problems.

    Implementation of Apple to iCloud library caused similar problems when I tried first. He changed most of my files of songs (according to retrospective). When this happened, I have restored the original files of the song from a backup and off the musical library to iCloud. I gave Apple several months for bugs and the week last tried railway. This time, it seems to go smoothly and none of my songs files have been changed. Now I'm enjoyimg music Apple and the possibility to add streaming music to my playlists.

    I like to be able to view my pictures on all my Apple devices, and when the next tvOS comes out soon, I'll be able to view my library on my Apple TV iCloud too. So I won't restore all my photos from a backup, then off iCloud photo library. Here's hoping that I find out later that one of my favorite photos are definitely missing or altered.

    El Capitan 10.11.3

    1.3 photos

    iMac (24 inch, early 2009)

    Based on examination of a small percentage of the total number of deleted duplicates, Photos seem to be taken of intelligent decisions on how to remove duplicate.

    I noticed similar symptoms.  When I import a picture that is a duplicate of one already in my library of Photos, both copies will share the same original image file in the folder of masters. Photos allows you to import duplicates, but will store only one version. This makes it almost impossible to replace JPEG corrupted by the restored versions of a backup.

    You can watch iCloud checking for duplicates while you download new photos. Launch the Console.app and look for the process 'photomodell '. You will see many entries like this:

  • iCloud library download not any photo library

    Hello

    I decided to start using iCloud photo library, so I checked the option "Préférences"-> "iCloud" Photos (version 2.0). He started to download items very well, but I noticed it is not downloading the entire library of Photos. My photo library contains 7065 photos and 151 videos, but Photos only started to load about 2500 points on iCloud library after activating what is 16.5 GB (see screenshots). When you look at the size of "Library.photoslibrary Photos" is 46.5. Does anyone know a reason for this difference? Thank you

    It'll take some time according to the signal from your ISP and Wi - Fi.  Make sure that your signal is good.

  • Unable to choose "iCloud library" after the restoration of Mac

    Hello everyone, this is my first time, ask a question here.

    I have a MacBook Pro with a library of 57 214 (317 GB) photos stored on an external hard drive. I recently downloaded all these photos to iCloud library (it took 5 days!) but just yesterday, I had to do a clean OS install. Since then, I tried to implement the pictures once again.

    My library on the hard drive is set as the system library, but when I select 'iCloud photo library' with the option ' download originals of this Mac ", it selects, then begins to download, it cancels the. If I try to select it again, the same thing happens.

    Two minutes later...

    Can someone tell what I can do? Should I remove the pictures from the cloud and try again?

    The problem may be that the free storage is not enough to download all original icloud in addition to the pictures already in your library.

    It might be easier to download the library of iCloud to an empty library instead of download the. library again.

    Do you have plans in your photo library, you need to save or invested a lot of work by naming the faces?

    Otherwise, move your existing photo library to an external drive as a backup copy, then remove the library of your internal drive.

    • Launch of Photos with the options key held down to bring up the library Chooser Panel.
    • Select this option to create a new library.
    • Make this new library your system photo library and activate iCloud.  Your photos and albums will begin to download. It will be faster than the download. Once again and the merger of the two libraries.

    But the download will not restore the named faces and not projects. IF you keep the original library to access your projects and have a reference for the faces that he will have to restore.

  • Can I remove the library from my Mac after the photos are uploaded to iCloud to free up storage space?

    My Mac Book Pro storage is almost full, and I would like to transfer my photos to iCloud and remove them from my Mac. How can I do this? And how to display in iCloud?

    With iCloud library enabled, you cannot delete a photo on a device (or iCloud.com) without deleting each device which uses iCloud photo library (iCloud.com). In order to save space on your mobile devices (and indeed your Mac if you want to) turn on the optimization of the pictures on these devices (settings > photos & camera > optimize storage on your mobile device and Photo preferences > optimize storage on your Mac)

    Dynamic optimization, it reduces the resolution of your photos, if necessary, so that you don't notice it occurring initially. However, when necessary, it is very effective, and users have reported libraries being optimized for much less than 10% of their original size in some cases. My own library is about 9% of its original on my phone size.

  • Images deleted (and videos) icloud library do not disappear into the folder of the masters

    I've got iCloud Library set up on my Mac OS X 10.11.6 and my iPhone iOS 9.3.3

    I have 300 + pictures and videos in my library to iCloud and then I recently deleted 50 + useless pictures and videos on my Mac to prepare a backup on Google Photos for the first time. I then tried Google pictures and to my surprise, the pictures I deleted still get uploaded to Google pictures even if I them deleted on my Mac, still 300 + of them.

    I am looking for .mov in the masters in my library folder, and I always find my deleted videos. I tried to use unwanted CleanMyMac to photo but it is not deleted.

    Is it possible to remove the so-called "deleted" photos and videos without completely deleting my library of Photos, or should I make a cool library to start over?

    Give 30 days to remove or open the recently deleted folder and delete now

    and to get rid of CleamMyMac - it is Malware total and may have damaged your library or your system and can be the cause of your problems - do not install MacKeeper

  • Photo library on iCloud and on my Mac?

    Now that I use iCloud for my Photo library, I can access of course from other devices, including another Mac. But not from the original Mac where I had the library on an external drive. Whenever I want to open Photo on the Mac, it will search the library on this external drive... so, what's the point of having the library on an iCloud? The reason why I wanted to iCloud had to move more freely and do not have to connect to each time the drive.

    Looking for answers on this topic, I can not find. Everyone out there can throw me a light? Thank you.

    iCloud library is mirrored on your Mac. So the behavior you see is expected.

  • Always about 3000 photos do not download to the icloud library. It has nothing different in size or the type of photo as the once that have been downloaded. Any ideas?

    I downloaded my library of images (30000) together in icloud. However, about 3000 of them just won't download. I checked and they are nothing in the size or format, like the rest of the photos. All Jpeg with normal file sizes.

    I already posted this question with screenshots, but no answer yet, try another...

    Can you tell us more about the second photo, which does not download?   Can change you it? Can export you it?

    Try to identify the first photo that always must download and does not.  Most of your pictures will be perfectly okay, but a bad point could hide the progression. A video or a photo in a format not supported.

  • Hello! If I icloud library disabled, will be always saved pictures? I know that your backup stores the photo library of all devices and because I'm not all devices to be synchronized I think I'm safe and won't lose my pictures/videos. Right?

    Hello! If I icloud library disabled, will be always saved pictures? I know that your backup stores the photo library of all devices and because I'm not all devices to be synchronized I think I'm safe and won't lose my pictures/videos. Can someone please clarify?

    If you want your photos backed up, you must import them into the photos on the computer application that synchronize you with. iCloud photo library is a repository for all the photos for a given iCloud ID. However, it is not required for the care of your photos. I do not use iCloud photo library - import my photos into the library of Photos on my Mac.

    A backup of your device iCloud will save your current film, but if you remove anything from this film, then it will not be available for retrieval at a later date, because backups replace the previous backup version. A backup is so not an archive safe for your photos or videos.

    Photo stream keeps the last 30 days or 1000 photos taken with your camera if you have Photo Stream on, but once again, it's a temporary storage that gets crushed. Photo stream is intended to provide a method of sharing photos between the signed devices on the same iCloud account, but is not intended as an archive.

    Import your pictures and videos on a computer means that all photos and videos are kept in a library on your computer and will be accessible. It is the only safe way to archive your photos:

  • Transfer of the photo library to new Mac via iCloud

    I bought a new iMac to replace an old MacBook Pro.  Rather than a Migration Assistant, I opted to do a fresh install of things since the MBP had years and years of junk on it.  In any case, of the MBP, I downloaded the very large library of Photos to iCloud (which eventually took more than two weeks).

    On the new iMac, in pictures, I checked 'use iCloud' and ' download origiovals full resolution for this Mac. "   Now I see in the preferences in pictures (on the iMac), it now says "DOWNLOAD files 13 500 to iCloud.

    I'm confused by the present, since there is no native picture on the iMac, then what, exactly, he's trying to do? All photos should not be a descendant of the cloud, does not extend to it?

    Furthermore, if I deleted the file PhotosLibrary on the iMac and copied the file PhotosLibrary of my old MBP and continue to synchronize with iCloud, the process would be quite smart to know tha all these pictures are already in iCloud and don't have reuploaded (or may have duplicates of everything)?

    Life was so much simpler before decide me to (try to) link to the photos between my Mac, iPhone and iPad via iCloud.  Come on, Apple. "What happened to"it works"

    Furthermore, if I deleted the file PhotosLibrary on the iMac and copied the file PhotosLibrary of my old MBP and continue to synchronize with iCloud, the process would be quite smart to know tha all these pictures are already in iCloud and don't have reuploaded (or may have duplicates of everything)?

    Whenever you open a library to use with iCloud photo library, the Mac will download and compare all the pictures with iCloud.  He will try to avoid duplicates and probably succeed.

    If you have already invested a lot of work in your library on the MBP, if you have created projects - book, calendars, appointed the faces, it would be better to copy the library. The names of faces will not iCloud, also download your books and calendars will be missing.

    See: use Photos and photo library on several Macs - Apple Support iCloud

    But if you don't need to save the labels of faces and projects, it should be faster to download the photos to iCloud.
