And if you’re wondering what tech reviews say about Gemini 2, wonder no more: we’ve gathered some of them below.
“I’ve been an active user of MacPaw’s Gemini software since its inception, and Gemini 2’s release today has made me fall in love with it all over again. In just the initial scan, Gemini 2 found more files and more places where I could intelligently clear and save space on my Mac.”

- 9to5mac
“If you want to clean up your Mac, but are trepidatious about digging around in your files and accidentally deleting something important, Gemini 2 has a lot to offer and makes the whole process very simple.”
“With Gemini 2 there’s little reason to fear duplicates. It has a polished, intuitive user interface and the brains to differentiate copies from originals by testing them against nearly a dozen different parameters. It’s also much faster, especially compared to digging through thousands of files and folders the old-fashioned way.”

Great… but some crashes for large data scans


I was an owner/fan of Gemini vers 1.0 and have recently purchased this version as well. Despite the feedback below, I think its probably the best application for what it does.

Here’s what I think works really well, and what I think not so much:

The Well:
- The duplicate detection is spot on. I’m always paranoid about it not actually selecting duplicate files. More often than not I trust but verify. I’ve never had it screw up the duplicate finding.
- The scanning works quickly.
- I’m enjoying the smart behavioral selection feature.

The Not so Well:
- It may be because I have a LOT of files to sort through, but the app crashes a lot with big scans (>50GB duplicates?).
- Its very slow sorting through those big scans.
- Its tedious to review findings. When sorting I can’t select multiple files within a file set. i.e. if it finds multiple versions of a particular file, and want to manually select or unselect for removal. It has to happen one at a time, and there’s a delay for each one.
- I love I can export detected duplicates to a text file, but I can’t actually bring those back into the application to re-process. If there’s a crash it doesn’t always remember my previous selections, and this file export requires me to use another tool to process and remove.

best duplicate finder i’ve used


photography and drawing are my hobbies. i have a photo archive of over 25K pics and another with many hundreds of drawings. As you probably know, many apps like this just grab all versions of a pic that are close to each other or similar. Gemini is more fine tuned. this app detects small differences, which is great. It will notice if i change just a few lines on a drawing or alter a small part of a photo. the price doesn’t bother me - i paid for it once a couple of years ago, i keep getting the updates free, it always works well and i use it constantly. good value

App apparently destroyed hundreds of photos and tech spt is ignoring me

Crisis Manager

I have been ignored for four days now by Gemini tech support after an initial exchange of emails about how the Gemini “similar photos” function appears to have PERMANENTLY deleted hundreds of my photos through my iPhone8+ (and therefore also from my Cloud account), although it’s not supposed to be able to do that. I’m an expert user, have owned/used computer continuously since the early (gasp) 1980’s. I know how to follow app instructions - yet this happened. I have also tried to reach out to MacPaw on social media - no response. BUYER BEWARE. UPDATE - I reached MacPaw support, finally - and they had no solution for me. They claim their app couldn’t have produced these results. Yet I’m still missing my photos.
