I have a ton of photos on my Mac and I think many of them are duplicates. My storage is getting full and I need to clear up some space. Can anyone recommend a good duplicate photos finder tool for Mac? I need something reliable and effective. Suggestions?
Oh boy, I so hear you on the storage woes. Macs just seem to gobble up space with all those photos, huh? 
But fret not, there’s light at the end of this tunnel.
First off, the Photos app on your Mac does have a relatively decent in-built feature for spotting duplicates. However, it’s not foolproof and can miss some sneaky ones.
Here’s the deal: for a more robust solution, I recommend Gemini 2. It’s pretty intuitive and makes finding and deleting duplicates a breeze. You just drag your photo folders or the whole Photos library into it, and it scans for dupes. You can then preview and delete the duplicates within the app itself. Easy peasy!
Another worthy mention would be PhotoSweeper. It’s comparably intuitive and does a thorough job. It has various modes for finding duplicates, including a face comparison feature which is super handy.
If you’re into free tools, there’s a nifty app called DupeGuru. It’s less slick compared to paid apps but totally gets the job done. Just be prepared for a bit of a learning curve since its interface isn’t the most user-friendly.
To sum it up:
- Gemini 2
- PhotoSweeper
- DupeGuru (if you’re on a budget)
Deleting duplicate photos will not only free up a ton of space but also make your photo library less chaotic. Now go and reclaim that storage space! 
Alright, running outta space, huh? Classic Mac problem. Besides the ones @sterrenkijker mentioned, have you tried using the CleanMyMac X app? It’s not just a duplicate finder; it does a full system sweep and cleanup. Think of it as the Swiss knife of Mac maintenance. A bit pricey, though, so you might wanna weigh that.
If you’re into the DIY route, running smart searches in Finder can partially do the job. Use Finder’s search feature to sort out photos by date and size, helps in locating similar ones. Combine that with manually eyeballing through the similar-looking thumbnails. Tedious, but hey, it’s totally free.
For the technically brave, there’s Terminal. With a little bit of shell scripting, you can set up commands to locate duplicates based on file size and other attributes, though this approach is defo not for the faint-hearted.
To add a twist, backup your current library before doing any massive deletes. Something like Time Machine could be a lifesaver if things go south.
And just one tip - streamline your photo-taking. Sometimes less is more, y’know? Good luck avoiding the Mac storage monster.
OMG, storage space on Macs - the eternal battle! While @reveurdenuit and @sterrenkijker offered some great tools like Gemini 2, PhotoSweeper, and DupeGuru, let me throw another hat into the ring: PowerPhotos.
PowerPhotos:
- Pros: Integrates smoothly with the Mac Photos app, lets you compare photo libraries, has a straightforward interface, and offers previews before deleting.
- Cons: More expensive than some other tools, occasionally slow with larger libraries.
If you prefer the manual route, Apple’s own “Smart Albums” in Photos can help. Create a Smart Album to group photos by certain attributes like file size or date. This way, you could spot duplicates visually, though it’s time-consuming.
DIY Manual Method:
- Open Photos app.
- Go to File > New Smart Album.
- Set criteria like filename or date.
- Visually inspect for duplicates.
For free solutions on a tighter budget, try Cisdem Duplicate Finder. It’s a middle ground between flashy paid solutions and the clunky free tools, offering an easier interface compared to DupeGuru but without the same advanced features as Gemini 2.
Lastly, always back up your library before cleaning up. Whether you use Time Machine, iCloud, or an external drive, having that safety net can save you from accidental data loss.
Final words? A mix of automated tools and manual checks might just help reclaim that valuable storage space. Happy decluttering!
