Switch Photo Library

I have a system photo library and a archive photo library. I double click the archive photo library icon and I get the "do you want to "Switch Libraries" dialog box. I click "Switch" but it does not switch. Is this a bug, or is there a solution?

I'm not doing anything but clicking the "Switch" button. Photos closes, then opens again, but the library is not switched. I attached a screen shot of the council errors, which have no meaning to me. I tried moving my archive library file to the desktop, but that made no difference. I option clicked the "Switch" button while in Photos and that brings up the change library dialog box. Doing the change that way does work. It's not that I can't change the library, it just doesn't work as expected. I will find the OSX 10.13 combo updater and give that a try, but there is limited value to spending too much more time trying to figure out why this doesn't work like it should.

Does it work on your computer? Double click another Photo Library in the finder. What happens?

It is working for me, if the Photos library is on a drive with a compatible file system and not used by Time Machine. Is your "Photos Library Older" on an external drive? If yes, what is the file system on this drive? Has the drive ever been used by Time Machine? Are you using the library from. a different user account as well?

Are you running 10.13?

yes. On two MacBook Pros and one iMac. Switching is working.

. I click "Switch" but it does not switch. Is this a bug, or is there a solution?


Are you waiting long enough for the current library to close? Photos will need to close the current library first, before it can switch to the archive library, and that can take a long time.


You may want to open the Console.app the next time you try to switch between libraries and watch, if the Console will show any diagnostic messages, while you are switching. Perhaps there is a clue t what is going on.

A Combo Updater will only be released, after there is at least a second version of macOS 10.13. Right now, there is only one official version of High Sierra, so no need to combine several updates of High Sierra into a Combo update.


If you are currently running Sierra and want to upgrade to High Sierra, you need the full installer for High Sierra. You can use the "Upgrade Now" button on this page to get to the High Sierra Upgrade at the AppStore: https://www.apple.com/macos/high-sierra/


If you are already running High Sierra and want to reinstall it, it would be easier to but into the Recovery partition and reinstall on top of the current system. OS X: About OS X Recovery


I'm not sure, that reinstalling will help. A "sandbox" error message usually means a problem with the file ownership or permissions on the home folder. Reinstalling the system does not fix problems with the user home folder, it only replaces the system files. If it is problem of file ownership (access control lists) in your home folder, you either need to repair the permissions and file ownerships for the complete home folder or surgically remove only the items that do not work.

But if you want, give reinstalling a try, it might also be a problem of an incomplete system installation.

There seems to be a problem with Photos's sandbox.

You could try, if erasing the sandbox (it is in the Containers folder in the user library) will help. but that will cause again a new upload to iCloud, if you are using iCloud Photos Library, because Photos will forget everything you set in the Preferences - the location of the system library, the iCloud settings.

Do it only as a last ressort, if nothing else will help.


To delete the Photos sandbox in Containers:

  • Quit Photos, if it is running.
  • Open your user library in your home folder (not the top most Library folder on your system drive).
  • Delete the complete folder ~/Library/Containers/com.apple.Photos/ and restart the Mac, then try again.

Your user library may still be hidden. If you cannot see it in your home folder do the following:

  • To reveal the hidden User Library:
    • Move the complete folder ~/Library/Containers/com.apple.Photos to your desktop. Move the entire folder, not just the contents.
    • Bring the Finder forward by clicking on the Desktop or the Finder icon in the Dock.
    • Select your user/home folder (with the house icon in the Finder sidebar)
    • With that Finder window as the front most window, press the key combination ⌘J to bring up the View options.
    • In the View options panel enable ’Show Library Folder’. That will make your user library folder visible in your Home folder, if it is still hidden.
    • Open your Home folder, then the Library folder, then Containers.
  • While you are about it, delete also ~/Library/Preferences/com.apple.Photos.plist

Restart the Mac and try again.
