Apr 01, 2020  Designate a System Photo Library in Photos If you have multiple photo libraries on your Mac, you can choose one to be the System Photo Library. The System Photo Library is the only library that can be used with iCloud Photos, Shared Albums, and My Photo Stream. Starting with OS X Yosemite 10.10.3, Photos replaced iPhotos on the Mac. If, like my wife, you kept using iPhotos before easing into Photos, you’ve probably got two different photo libraries on your Mac, which can be a pain and a storage hog. Thankfully, you can merge ‘em. To migrate another photo l. Actually, there is a much simpler way to combine two photos into one page (one pdf) on a Mac. Open a new powerpoint file, open the photos you want to join or save into one PDF, use the Crop command (Shift+Control+Command+4) to crop the images one by one and paste them in the powerpoint file. If you have more than two libraries, repeat the same steps for each library you want to merge. Once you’ve processed the rest of the libraries, open the first one up again, enable iCloud Photo Library on it, and let it redownload all the full sized photos that were uploaded from the other libraries. Jul 27, 2019 Rather than having multiple iTunes library which is disorganized and scattered across multiple computers, take a few minutes out of your day and merge iTunes library into one. Not only that but if you have more than just two iTunes libraries then you are able to merge them too! Simply merge them one at a time and all into the same place.

• Feb 26, 2018  The third group is Mac users who have and use Photos. The fourth group needs multiple photo libraries. Here are two ways you can get and manage multiple Photos photo libraries on your Mac. First, if there is a scourge that existed on my Photos and iPhoto library for years, and exists on the new Photos, too, it’s photo duplicates.
• Merge through iCloud Photos. Apple’s iCloud Photos service offers the best solution for merging libraries. The trick is that whenever you designate a library as your System Photo Library, Photos automatically uploads all images that aren’t already present, adding them to the photos already in iCloud Photos.

Merging Photos libraries

Update (11/3/2015): PowerPhotos 1.1 now supports library merging!

Unlike iPhoto Library Manager, PowerPhotos does not yet have the capability to merge libraries together. This is something I’d like to add to PowerPhotos, though I can’t make any concrete promises, since doing so partially depends on whether Photos itself adds a few necessary enhancements. In the meantime, since I get asked about this a lot, I thought I’d put up a quick summary of the existing methods to get your content all together into a single Photos library.

Merge your iPhoto libraries beforehand

At this point, most people looking to merge libraries together have existing iPhoto or Aperture libraries that they’re either planning to migrate to Photos, or have already done so. Since merging options with Photos itself are very limited, if you do want to merge your libraries, it will be much easier to first merge everything together as iPhoto libraries, then take the resulting merged iPhoto library and migrate *that* to Photos afterward.

If you haven’t migrated any of your existing libraries yet, then simply use iPhoto Library Manager to merge the libraries together first, then open the merged library in Photos to let it perform the migration (Aperture can also be used to merge iPhoto libraries, though it doesn’t perform duplicate detection like iPLM does). If you have already migrated some/all of your iPhoto libraries though, you may still be able to follow this route. Photos leaves the original iPhoto library intact after performing the migration, so as long as you haven’t deleted the iPhoto library yourself, you should be able to go back and perform the merge, then migrate the merged library to Photos.

Combine Mac Photo Libraries

To migrate an iPhoto library a second time, the easiest way is to use the File > Migrate iPhoto Libraries command in PowerPhotos. Just check the box next to the iPhoto library and click Migrate, and PowerPhotos will take care of the details. To do it without PowerPhotos, you’ll need to open the library in iPhoto first, and it should give you a brief messing saying that the library has been migrated to Photos already. Click the “Open in iPhoto” button, then close the library back up. Then, take the iPhoto library and drop it on the Photos icon in the dock, and it will perform the migration a second time.

If you have imported any newer photos into Photos since you performed your first migration, those photos will not have been imported into iPhoto, and thus will be missing from the merged library. If this is the case, you’ll just need to either export those photos from the first Photos library that you migrated, then import them into the second library, or just reimport/redownload them from your iPhone or wherever they may have come from.

Use iCloud to merge your content

The other technique that can be used here is to merge everything together by uploading it into your iCloud Photo Library. This will work with any Photos library, whether it was migrated from iPhoto originally or not, and can be used to merge libraries on different Macs (though they must be using the same iCloud account). The basic workflow for this is:

Aug 04, 2016  I've been having a lot of problems getting my music library/playlists to appear in Apple Music. I think there may be an issue with iTunes because 'Update iCloud Music Library' is greyed out an unclickable when i go to File-Library. Jan 16, 2020  Go to the General tab and select iCloud Music Library to turn it on. If you don't subscribe to Apple Music or iTunes Match, you won’t see an option to turn on iCloud Music Library. If you have a large music library, it might take some time to upload. Mac itunes icloud music library box gray.

1. First, you’ll want to choose which one of your libraries you want to ultimately be the merged library, that will ultimately hold all the content.
2. Open that library in Photos, open the preferences window, and click the “Use as System Photo Library” button. Then, in the iCloud section of the preferences, enable iCloud Photo Library. Make sure that the “Download Original to this Mac” option is enabled.
3. Photos will start syncing your library with iCloud, uploading all of the full size photos from your Photos library.
4. If you already have other devices with iCloud Photo Library enabled (e.g. your iPhone or iPad), in addition to uploading all the photos in your Photos library, it will also download any photos that have already been synced with those devices.
5. Once that library has been fully synced (this may take quite some time if the library is large, even multiple days), open a different library in Photos, and repeat the same steps. The content from the second library will be added to what’s already in iCloud Photo Library.
6. By default, syncing the second library with iCloud will also download all the content from the first library into the second library onto your Mac. However, if you enable the “Optimize Mac Storage” option in the iCloud preferences in Photos, that will only initially download smaller thumbnail versions of each photo, which can speed up this part of the process and use less disk space and bandwidth.
7. If you have more than two libraries, repeat the same steps for each library you want to merge.
8. Once you’ve processed the rest of the libraries, open the first one up again, enable iCloud Photo Library on it, and let it redownload all the full sized photos that were uploaded from the other libraries.

Merge Two Photo Libraries Mac Os X

While this is an effective way to get your libraries merged together, there are a few significant downsides:

Mac Photo Library Management

1. If you have a significant amount of photos that you need to merge together, it’s going to take a lot of time, bandwidth, and disk space to perform all of this uploading and downloading from iCloud. For really large collections, you may be looking at a project spanning multiple days or even weeks.
2. iCloud only provides 5 GB of storage for free, so if your collection exceeds that (which is not difficult), you’ll need to purchase one of Apple’s larger storage plans, at least while you’re doing all the syncing. If you’re not interested in using iCloud Photo Library in the long run, it is possible to bump up your storage for a short time, remove the photos from iCloud once you’ve gotten everything downloaded back to your Mac, then move your account back down to the basic storage plan.
3. If you have an iOS device also synced with iCloud, it will start to download all the content that you’re uploading, which can sometimes eat up bandwidth and battery life. You may want to enable the “optimize storage” option in the Photos section of the Settings app on your iOS device before starting, or just turn off iCloud Photo Library altogether if you want to prevent that.
4. There are a few limitations to what will sync through iCloud, which you can read about here

Those are the main two techniques that can be used to merge your photos together into a single Photos library. Each of them has its downsides, but hopefully if you want to get all your photos in one place, one of this options will work for you.
