I like where the app is going, but it's in desperate need of a proper icon!

There's a bug in Lyn I've reported numerous times - and never received word from the developer. If I select a series of images I cannot do a batch copyright or keyword on these selected images. A problem I had hope the developer would correct. But when I can't get even a reply to my question that's disappointing.

problem with the memory was fixed I think, and it is the best image manager and viewer together with XnViewMP.

I like Lyn a lot and own a copy. I also own a 4K display which I'm using in Retina mode. Unfortunately "Zoom to Full Size" does not give per pixel blow up (1.5 screens with my 6000 x 4000 pixel images) but blow up to 2x (my screen is set at 2560 x 1440 Retina). I hope the developer gets around to adding full Retina support. It's not there now. This is really a problem as it means that even in fit to window mode the pixels may not be 1 to 1 (at first glance it appears they may be). More time wasting testing for me and less trust and certainty in the use of Lyn. Lyn promises to be Retina aware. I hope Mirko can iron out these Retina bugs. In the meantime, I've had to switch to LilyView for browsing images (Preview does not work properly in Retina mode on a 4K monitor either). LilyView behaves as expected. It's from the same team who developed DaisyDisk (another application I really like). LilyView doesn't have much of the advanced folder browsing and file/EXIF management tools that Lyn offers, so I'll be using the two in parallel for now.

I like Lyn, but unfortunately it gobbles a lot and lot of memory. Slows down my iMac to a crawl when it's open. Even when it's not open but sitting in the dock, still heavy. It is not lightweight at all.

Agree. If you have a lot of images (60K) it essentially chokes the app. There is a serious memory leak problem with this app. If you have just a few hundred or so you're ok but as your library grows it becomes useless. I run a late iMac with 32G M

@ fsgrafix...what do you suggest to use instead ? Is Pixave better ? Or to go back to Photos ?

IMO, the best image viewer, simple, effective, powerful. Constantly updated, great support. It's a no brainer.

Using it for five years now. The interface is badly designed (terrible spacing among groups and folders in left panel, toolbar items seems unfinished). Developer choose to add some image adjust tools but never improved the interface. Anyway, the app does quite well what it is designed to do. Tried other image viewers and decided to keep Lyn due to its simplicity and good performance.

I'm using Lyn(full version) for the last couple weeks. It shows everything on your computer. And I mean everything, including your home folder, documents...etc. In short, all of Finder is there. You can only "hide" it. So, Lyn is not only photo organizer. It is just like an enhanced Finder. No, I don't need it. Unbound on the other hand, is strictly photo organizer in the most simple way. It will organize only photos which you will bring in.

want to correct myself:
I was using XnView, which is very fast, although the interface is very different, but I like it. It does the same thing, it shows every single image on your computer, just like Lyn. I mentioned also Unbound. It has a problem loading over 11,000 images. But the developer promised to fix it.
So, I'm going back to Lyn.
Something else, I removed all my images from Photos, and placed them in a folder on Desktop, and on external hard drive.

This is actually a good app. Although the GUI isn't very modern to today standards it is very easy and simple that just works without a steep learning curve. The price is a bit too high imo. Still worth checing out.

I've been looking for an OS X alternative to the excellent FastStone on Windows. So far this is the closest I've found but it's sadly quite inferior to FastStone. My main gripes are -1: It's slow, really slow. It generates thumbnails every time I enter a folder (caching it seems isn't something Lyn can do) and it's a slow process. Then scrolling through screens of thumbnails is oddly clunky and juddery. They're just thumbnails, this should be lightning fast. 2: There's no option to scale up smaller images to fill the screen automatically. They can be manually zoomed (in large increments), but without filtering, so they look really ugly. 3: It crashes quite a bit. It's a start, but I think the dev could improve this significantly.

Try ViewIt. It's all I use on a Mac to view images :

@ philip_baxter: Though I can't compare Lyn with FastStone as i've never done Windows, you might try Emulsion (which is what I currently use) or you can look at Media Pro where you can get a decent price if you've ever used iView Media Pro or Expression Media..
