Troubleshooting Deleted Photos:

Loss of data is something you would have agreed to upon opening an Apple Account. So, if the following does not work, then they are gone. That's just the way it is :(

Three Tactics to Try:

A. Check iCloud Directly:

See if they reside in iCloud Photos. Log in here: https://www.icloud.com/photos

B. Use a Time Machine Backup:

Did you backup your Mac, recently? If so, then restore your Mac from that. You'd backup you Mac prior to doing so, and then restore your data from the backup you just created, through use of Migration Assistant.

C. Where Else to Check:

• PC
• PDA
• eMail
• Mac Device
• Cloud Storage
• Android Phone
• USB Flash Drive
• External Hard drive
• Secure Digital Card
• Compact Flash Card
