Are you tired of encountering the frustrating error message 'AdtApp failed to load Manage Devices List' when trying to access your iPhoto library on a Mac running macOS High Sierra or earlier? This article will walk you through a series of troubleshooting steps to resolve this issue and get back to enjoying your photos.

Step 1: Check for Updates in the App Store

Before diving into more advanced solutions, it's essential to ensure that all applications, including iPhoto itself, are up-to-date. Launch the Mac App Store from Spotlight or Applications/Utilities/App Store (depending on your macOS version). Sign-in with your Apple ID if prompted and click 'Update' next to any available updates.

Step 2: Reset System Preferences

Sometimes, simply resetting system preferences can resolve various issues without deleting user data. To do this:

1. Quit iPhoto completely by Force-Quitting it (Command + Option + Esc on Mac) or right-clicking the iPhoto icon in Dock/Menu Bar and selecting 'Quit.'

2. Go to System Preferences > 'Your Apple ID' > General.

3. Click 'Reset Now' when prompted.

Step 3: Edit Info.plist File

If resetting preferences didn't work, you may need to edit a specific file manually:

1. Quit iPhoto again by Force-Quitting it (Command + Option + Esc) or right-clicking the iPhoto icon and selecting 'Quit.'

2. Launch Finder and go to Applications > iPhoto.

3. Right-click/Control+click on iAppSupport inside this folder, then select 'Show Package Contents' from the context menu.

4. Double-click on Info.plist in the next window that appears using your preferred text editor (like TextEdit or Atom).

5. Find the line that says `java.exe` and replace it with `/Applications/Java/jre1.8.0_51/Contents/Home/bin/java`.

6. Save changes to Info.plist.

7. Relaunch iPhoto by double-clicking its icon in Applications or searching for 'iPhoto' in Spotlight.

Step 4: Reorganize Photos and Check Permissions

If none of the above steps resolve your issue, it's worth trying a more drastic measure:

1. Launch Disk Utility (Applications/Utilities) and select your startup drive from the left sidebar.

2. Click 'First Aid' at the top right corner to repair any disk errors.

3. Once completed, quit Disk Utility and restart your Mac.

4. Upon booting up again, go to Applications > Utilities > iPhoto Library Manager (if you have it installed).

5. Select all libraries except for the problematic one(s), then click 'Export' and choose a new location.

6. Relaunch iPhoto with these newly exported photos inside.

Step 5: Reinstall iPhoto or Switch to Photos App

If none of the above steps resolve your issue, you may need to consider reinstalling iPhoto entirely:

1. Go to Applications > Utilities and launch 'Applications' (not Application) folder.

2. Right-click/Control+click on iPhoto and select 'Move To Trash.'

3. Empty Trash by right-clicking/Option + clicking the trash icon in Dock or using Finder's 'Empty Trash.'

Alternatively, if you're comfortable with switching to Apple's default photo management software:

1. Go to Applications > Utilities and launch 'Application Support' folder.

2. Find a directory named com.apple.iPhoto inside this folder (it may be hidden; press Command + Shift + period on Mac).

3. Move all contents out of here except for the Library folder itself.

4. Restart your Mac by shutting down completely instead of using Apple Menu > Shut Down or pressing Command + Option + Power button.

5. Upon booting back up, launch Photos from Applications/Utilities (or search 'Photos' in Spotlight).

By following these steps carefully and methodically, you should be able to resolve the frustrating error message 'iphoto 9.6.1 says loading' when trying to access your iPhoto library on a Mac running macOS High Sierra or earlier. Remember that sometimes, simply restarting your computer can work wonders!
