Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
I can't find find what thread you had followed. Could you please tell me what have you tried so far ?
Go to your Pictures folder and do you see your iPhoto Library there ?
What version of Mac OS X are you using ?
In Finder, click on Go menu and select Home. In home folder, open Pictures folder and how many libararies you see there ?
Select that iPhoto Library, press Command and I. This will bring Get Info window. What is the size of that iPhoto Library ?
What is the size of that iPhoto Library you can see in Pictures folder ?
It is only 7MB. What happened to the library ?
What is the size of other libraries there ?
In Spotlight search, type jpg and does it return any of your pictures ?
All your photos ? Scroll down on the results and select Show all in Finder. Do you see all your photos ?
Type jpb in Spotlight and scroll all the way down to the bottom of results. You see "Show all in Finder.." at the bottom with Finder icon. Double click on it and it will open the results in Finder. Under Images section, how many photos are showing ?
Spotlight will not show all pics. Open Finder window. In Finder window, you will see search box are top right (not on the top right corner of Mac's screen). Search jpg there
Under Images section, look on right side. It will show the number of picture it found with Show All option. Click it
Do you have more photos than this ?
These are the photos that are available on your Mac. Try this. Click on 'Show All' on right (in Images section). Then press Command A and this will select all pictures from the results. Now create a folder on Documents on in Pictures folder. Open that folder and press Command V and all those photos will be copied to this folder. Now open Photos app. Click on File > Import
Select the folder with your photos and click Import. This will import all of them to Photos app.
If the library is available on Time Machine, then Yes. It would be easier. Click on the Time Machine icon at the menu bar and select Enter Time Machine. Go back in Time where you had the photos. Open Pictures folder (in Time Machine). If you see the main iPhoto Library there, select it and click Restore button on right or bottom. This will restore that library to the internal hard drive. Let me know how it goes
You have to enter to Time Machine first. In Time Machine, click on Home folder or Picture folder in left column. Do you see the library there ?
Under Devices click Macintosh HD. Open Users folder. Open Home folder. Open Pictures folder and you will find the Library there (if it is backed up).
Or in Time Machine, press Shift, Command G and this will bring Go To Folder. Type ~/Pictures/ and press return. This will open Pictures folder
Can you check the size of that iPhoto Library ? If it is correct size, then restore that one.
You can select all those pictures and restore them to the Pictures folder or any folder to the internal drive. Don't restore them to Desktop folder
I believe it will not allow you to restore the entire Pictures folder, but just the contents of that Pictures folder.
Only if there is backup mode. Go further back into the time (like a week ago) and do you see working iPhoto Library ?
What is the size of that older iPhoto Library ?
Put it in the Pictures folder
Not the iPhoto. app. You need to copy the iPhoto Library from Pictures folder
Since the pictures are on your Mac itself, can you try my first suggestion ?
Close Time Machine. Search jpg on your Mac (in Finder). Copy all pictures to a folder and import them to Photos.
I'm just posting the steps again
Open Finder. In Finder window, you will see search box are top right (not on the top right corner of Mac's screen). Search jpg there
Click on 'Show All' on right (in Images section). Then press Command A and this will select all pictures from the results. Now create a folder on Documents on in Pictures folder. Open that folder and press Command V and all those photos will be copied to this folder. Now open Photos app. Click on File > Import
