Photos duplicates & wrong thumbnails after upgrade

2. I have tried to manually rotate photos to correct the thumbnails. Works 90 % of the time but I'm guessing I have thousands of mixed and faulty thumbnails so that's not really an option.

First try to correct all thumbnails by rotating back and forth. You can select many photos at once and rotate them at the same time using ⌘R and ⌥⌘R

2. Some pictures are now duplicate, with the exact same file name and file size. I'm afraid to remove them as I fear that it's actually another picture hiding behind the duplicate one that is showing? This is extremely frustrating.

That might be caused by edited versions. If you used adjustments in iPhoto that cannot be reproduced in Photos you may see the original and the edited version side by side.

After fixing the thumbnails look at the apparent duplicates if they are really identical. Are you seeing the duplicates side by side in moments or only in albums? If you have identical photos and not different edited versions of the same in the same moment you can delete one of the duplicates. A duplicate finder can help to identify them.

These three apps are compatible with Photos:

• Power photos: Fat Cat Software
• Duplicate annihilator: Brattoo Propaganda Software - Products
• PhotoSweeper: http://overmacs.com/photosweeper.html

I tried the rotate trick, but it's gonna take me probably 3-4 hours going through my whole album and that's really not in question

You can select man photos at once from the "All Photos" album. It should not take that long.

Is it possible in anyway to get another more competent app for photo management and merge all my files (without all the extra 1024, thumbnails and everything), just plain simple jpg transfer so I can get out of this mess?

It will depend on what you want. Professional photo managers will support a lossless workflow, like iPhoto and Aperture do, also Lightroom or Capture One. That means a library with saved originals and edited versions, previews, and thumbnails for speedier performance.

You could try Picasa for Mac, if you just want an index for photos already on your Mac.

3. Repairing the library with the option+command control. Didn't change a thing.

Since repairing the Photos library did not help, i'd try to rebuild the original iPhoto Library in iPhoto and then repeat the migration to Photos, hopefully with a better result.

Where re your Photos Library and the original iPhoto Library stored? In the default location in the Pictures folder or on an external drive?

So how do I rebuild the library, and does that come with any risks of losing data?

In your original post you said:

3. Repairing the library with the option+command control. Didn't change a thing.

So you already tried to repair the Photos library. I think you need to repair tor rebuild the original iPhoto Library and then migrate it again.

The original iPhoto folder shows 60-something GB and the new Photos folder show 70-something (without me even adding any more pictures, so I would guess there are gigabytes of wasted thumbnails, faces and weird apple stuff that I don't really want clogging up my expensive SSD drive).

The iPhoto Library and Photos Library are sharing the photos. (See: Photos saves disk space by sharing images with your iPhoto or Aperture libraries - Apple Support) The combined size of the two libraries is much smaller than the sum of the file sizes.

To rebuild your iPhoto Library make a backup copy if you do not have a current backup, and then try first to launch iPhoto while holding down the key combination option-command. Select "Rebuild".

repeat with "Rebuild Thumbnails".

Then migrate the rebuilt library again to Photos by dragging it onto the Photos icon. If this does not solve the problem, rebuild the iPhoto library with iPhoto Library Manager. The free trial will suffice: http://www.fatcatsoftware.com/iplm/

Try first, if you can update iPhoto. Which version did you have?

With the iPhoto Library Manger app I tried also to rebuild, but it too tells me that my iPhoto application is outdated and needs to be updated in order to compete with my OS (so sad that it's not possible to "update" iPhoto any longer)...

That depends. If you bought iPhoto from the App Store or ever updated it using the AppStore you should be able to update to iPhoto 9.6.1, the compatibility update for iPhoto. I am using both iPhoto and Photos on Yosemite. It is very convenient to have two libraries open at the same time.

If you missed the update, see this User Tip: Get iPhoto 9.6.1 if you didn't update before OS... | Apple Support Communities

Hello -

Following this thread as I had the same trouble. Seems to be out there and I'd love to know from the hosts if this is a real bug or the result of a corrupt iPhoto library.

When I did the same, I had some wrong thumbnails. Rotating helped but there were tons of them. And thumbnails from pictures long trashed.

With Apple's assist - I repaired system permissions, repaired iPhoto library and rebuilt the database. Attempted Photos again, same problem. Repaired the Photos library, made the trouble even worse.

Then, reinstalled the OS for 10.10.5 and iPhoto works great. I've not tried importing back into Photos YET. But was curious about iPhoto Library Manager and what your results were because iPhoto has worked without fault. I am waiting to hear back from Apple (and their engineering group who are assessing my database) as to what the trouble is. My case worker said perhaps wiping my drive and reinstalling - this seems extreme.

Not thread-jacking but leonie is a favorite.

Thanks.

Is it possible in anyway to get another more competent app for photo management and merge all my files (without all the extra 1024, thumbnails and everything), just plain simple jpg transfer so I can get out of this mess?

Yes there is. I use Media Pro 1 as my primary DAM (digital asset management) app and Photos/iPhoto for my special projects, i.e. books, calendars, etc.

If you still have your iPhoto library just follow this tutorial to migrate to MP1: iP03 - Converting an iPhoto Library to a Media Pro Catalog System

I believe MP1 can be used in demo mode for 30 days so you can try migrating your iPhoto library to it. If you don't like the results you can continue using what you have.

Hi,

Read this thread as I was having the same problem. After import from iPhoto to Photo many images clicked through to wrong photos and appeared fuzzy - like many photos lay on top of each other. Rotating would sort. Anyway, this might sound odd, but I happened to resize the photos using the sliding tool at the top - and it sorted it.

This has probably come too late for you, but I thought you should know. Also, might help others who find your thread with the same issue.

Hello.

I reinstalled the OS and am waiting on a call back from Apple as they have my database for examination. So, I have not tried to re-migrate the iPhoto library.

Did you have to resize all your photos at once and how did you do that? How large is your libary?

Also, my support person had a set time to call and did not. He was out of the office that day. When I finally called in they had a note saying they'd attempted to call me but it was a failed call - which isn't true. My faith in a new product is already sad!

Thanks,

H
