OS Catalina and iphoto

There is not update to iPhoto for running under Catalina. You can do one of two things:

1 - create a High Sierra or Mojave boot drive on an external SSD from MacSales.com connected with a SATA to USB 3 adaptor from Benfei:

Boot time is about 45 seconds. With High Sierra I can run iDVD, iMovie 6HD, iPhoto 9.6.1 and many other apps for specific projects.

2 - migrate your iPhoto library to Photos.

Although Photos is a bit different in it's GUI it's a much, more powerful image editor.

I need to order photos in file name order. Photos certainly does not do this

There's a workaround for that.

1 - select all of the photos in the library and either use the key combination of ⌘+N or the File menu:

That album can be sorted by Title.

2 - when new photos are imported drag them from the Imports window into the All Photos album.

If you want to assure that the titles are the same as the file name select photos and run this AppleScript on them: Script: Batch Changing the Titles to the Filenames with Extension (Dec 19,2018) or Script: Changing the Title to the Filename without Extension

The scripts compiled as applications can be downloaded from this tutorial site:  P01 - Applescripts from Photos’ User Tips Compiled as Applications

You cannot use iPhoto on Catalina. You would have to downgrade back to your previous system.

But you can open your iPhoto Libraries with Photos for mac to access your photos.

See: How Photos handles content and metadata from iPhoto and Aperture - Apple Support

Double click iPhoto Library to open it in Photos. You should be able to access all photos and albums, the events will appear as albums as well.

You couldn't have been using iPhoto with Catalina. It won't run in Catalina.

You should start your own topic and include information like:

• What app you were using to create the book.
• What system you were running?
• Describe what you're experiencing with your library.
• Is the library working?
• Where the library is located. If on an external HD how that drive is formatted and connected to your Mac.

iPhoto is not compatible with Catalina so you'll have to migrate your iPhoto library to Photos.

What is Apple doing to fix this situation?

Apple has replace iPhoto with Photos. Drag your iPhoto library onto the Photos icon either in the Dock or in the Applications folder. Read this Apple document: Notes on Migrating an iPhoto Library from iPhoto to Photos for Mac

You should not highjack a topic but start one of your own, describing in detail what your problem is, you Mac's setup, what you've tried already. That way you'll get undivided attention for your particular problem.

Also read the following before starting your topic: Writing an effective Apple Support Community Question - Apple Community

You have a problem that is different from the OP. You should not highjack a topic but start your own with detailed description of your problem(s). That way you'll get responses geared to your problem alone.

Try the Image Capture.app: It should be installed on your Mac:

Try again and post the exact error message, so we have a clue what might be going on on your Mac.

If all fails, revert to Mojave and migrate the iPhoto Library to Photos on a Mac, where you can run iPhoto to prepare the library for the migration.

This will have several advantages:

• You use iPhoto to repair or rebuild the iPhoto Library, if there should be a problem.
• You can remove incompatible media from the iPhoto Library. Catalina does not support all media formats, that you may still have in your iPhoto Library.
• On a system, where yuo can still run iPhoto, you can compare the migrated library to the old iPhoto Library and fix any items, that did not migrate well.

I just installed Catalina and now:

1. iPhotos no longer works, so I need to use the app Photo. That's OK, but...
   1. I managed to import my iPhoto library into Photo after a bit of trying.
   2. The photos loaded in and everything seemed OK, but..
   3. But after a reboot, the photos are no longer in Photo.
   4. I waited an hour for someone from their "Creative Media" department to help me then gave up.
   5. It appears that many of you have the same problem.
2. About 80% of my folder icons do not appear.
   1. The best their tech support could offer is for me to either manually replace the icon using the Get Info dialog and pasting in the proper icon for each of the folders or else to manually move the contents of all the now "corrupted" folders into new folders.
   2. I must have hundreds of folders that don't have the folder icon associated with them.
