Reader Celia Drummond had a Mac crash so severe, she had to upgrade her system from Mavericks to El Capitan—I didn’t ask about Sierra—although she was able to recover her data from Time Machine.

However, after using the iPhoto Library Upgrader, Apple’s recommended path for converting iPhoto 7 and earlier libraries to a newer format that iPhoto 8 and 9 can use, “The result is photos a fraction of their original size—most were between 1MB and 7MB each—and all are pixelated.”

My issue is that the Photos kept saying no permission and ask to repair the library to no avail in my time capsule after Catalina update. In the end I moved the library (400gb) to a hard disk that I formatted using my MBA (Catalina). The Photos restored the library and opened it successfully. Once Photos is closed, you will want to try and force a repair to your library. This is a built-in way for macOS to try and get rid of any potential issues. When opening the Photos app on your Mac, press and hold the Option + Command keys at the same time as opening the Photos app. Repair Photo library Photos provides the repair functions to fix for the broken and version-incompatible photo library. The Library folder contains many of the resources that installed applications need to use, including preferences, support documents, plug-in folders, and the files that describe the saved state of applications. It has long been a go-to location for troubleshooting issues with individual applications or components shared by multiple applications. Sign in to iCloud to access your photos, videos, documents, notes, contacts, and more. Use your Apple ID or create a new account to start using Apple services.

I never used the utility, so I don’t know what went wrong, but something did if that’s the outcome, or something is missing in the Time Machine backup. Because she can’t run the older version of iPhoto, she can’t simply rebuild the library, which is the usual suggestion. (I’d make sure you had version 1.1 via the link above, as older versions are out there, too.)

I’d normally suggest for forward version compatibility to try to find an intermediate version of software, which has been useful for folks with various older releases of the iWork suite (Pages, Numbers, and Keynote). However, the only course of action with an iPhoto 7 library is apparently to run it through the upgrader; you can’t just try to open it in iPhoto 8 (or 9). (I don’t have older libraries to check this out, so I’m relying on Apple and forum posters.)

If the upgrader just won’t work with the old library, the only real solution is to crack open the library and extract ones photos.

Control-click the iPhoto Library.
Choose Show Package Contents from the contextual menu.
Drag (to move) or Option-drag (to copy) the Masters folder to the Desktop or to another drive.
Launch the latest version of iPhoto 9 and import that Masters folder. Or launch Photos and do the same.

Unfortunately, you’ll lose a lot of information associated with photos and video that’s stored within the library, such as metadata, potentially some edits, albums, and other organizational elements. But this is better than losing the high-resolution versions of your media.

After importing the images and videos and making sure they’re the high-resolution ones you want, you can then use a de-duplication program, like PowerPhotos or Photosweeper 3 (review coming), which can clean up the low-resolution images and possibly help fix the missing metadata.

It’s easy from the perch of writing the Mac 911 column to appear as if I have all the answer. Dear readers, I do not. I am always delighted to research on your behalf, but sometimes problems fall into my lap that I know will help you all, because I’m unable to find a ready solution and nobody in any forum or on any blog has found an answer, sometimes across many years.

Photos for macOS is a bugbear for many of you, one of the most regular sources of questions. But I encountered a sync problem that no one has written in about, yet I can find a history of frustrated people across the Internet trying to solve it. I did find a solution—but you might not like it!

My problem emerged a few weeks ago, when I noticed that Photos for macOS on my office computer, an iMac running Mojave, was out of date. I checked my laptop Mac, my iPhone, and iCloud.com: photos were synced and up to date in each of those locations.

This has happened before, and I go through a series of escalating troubleshooting steps:

Quit Photos and re-launch it.
Using the Terminal to “kill” certain Photos-related background agents and jobs. (This is a little tweaky and can cause problems, so I hesitate to recommend it. In any case, it didn’t help.)
Restart my Mac.
Rebuild the Photos database by holding down Command-Option while launching the app and following prompts.
Disabling iCloud Photos and re-enabling it in Photos > Preferences > iCloud. This can force a re-sync, though often it’s relatively fast as Photos and iCloud seem to bypass pictures that are in both places.

None of this worked. After reading years’ worth of posts of people trying to overcome the problem, I tried one suggestion: deleting a deeply nested folder in the Photos library that tracks iCloud synchronization.

Warning! Apple doesn’t advise making these kinds of low-level changes. I strongly recommend making a full backup of your Photos library, if not a fresh full clone of your drive or forcing a Time Machine update, before proceeding.

Find your Photos library and Control-click it, and then select Show Package Contents. Now traverse down to:

private/com.apple.cloudphotosd/CloudSync.noindex

With Photos not running, I deleted the contents of this folder, which required entering an administrative password. I then-relaunched Photos.

Photos and iCloud apparently had a behind-the-scenes confab and decided my copy of Photos had never synced with iCloud at all. This led Photos on my Mac to re-upload about 45,000 images and videos, even though they were identical in my library at iCloud.com.

Fortunately, I have gigabit Internet service with no cap on usage and no overage fee. (The local legacy wired telephone company has rolled out fiber like mad and charges a relatively low amount for it—even less than slower service via a cable ISP.)

If you have more normal broadband service, even in the 50Mbps to 100Mbps range, or get throttled, blocked, or charged overage fees above a certain amount of monthly data, this won’t seem like a good solution to you at all. (Although during the pandemic, a number of ISPs with home broadband service have removed caps and overage charges, including AT&T and Comcast.)
