Whoah… Aperture is Running on macOS Big Sur

This is the first post in a long time I've made on Aperture, but it turns out (yes, this is old news) that you can run Aperture on Big Sur, with the help of a little app called… Retroactive.

The end of Aperture was announced on June 02, 2014 (for a bit of nostalgia, here's the article I wrote that day), and last updated in October 2014. Officially, macOS Mojave was the last version of macOS that supported Aperture. But for many users, the app has lived on. Personally, I froze an iMac at macOS Mojave 10.14.4 and have been running Aperture on there. Not for any new photos — regular readers will know that I've been using Lightroom for quite a while now — but for my old libraries. But I finally decided to put the time into migrating these old Aperture libraries to Lightroom.

That, however, is a different post. I'm in that process right now, and it's going… well… ish… but it's happening. I'm documenting it all so I can write a complete story, summary and advice once I'm done.

However in the process of starting this, I learned of a tool I'd never heard of before (someone probably told me about it and I ignored it, if we're being honest), and that's the tool Retroactive.

This is an open source project, and you have to download it from GitHub, but it's fully documented and easy to get to. Just visit the GitHub page and follow the instructions. You can read more about the app and its development in this Medium post.

Obviously I wanted to try this! So I downloaded Aperture from the App Store… I wasn't sure if it'd actually download (I thought in the past I'd seen a “not supported” error and it wouldn't download?), but it worked! You'll have to find it in your previous downloads (just click your name in the lower left corner of the App Store), as it won't show up in search results. 

Once installed, this is what you'll see in the Applications folder…

So, you download Retroactive, launch it, and it walks you through a couple of steps, and then…

Whoah. Holy crap. It worked.

I gotta say… I never thought I'd see Aperture running on a Mac Pro!! My library opened just fine. I suspect this will be a bit faster than the old iMac I've been running Aperture on ;-) 

Well, back to the process of converting this library to Lightroom. I'll update you as soon as that's completed. For now though… wow. I can't believe this works!

Have you compared what migrates to Lightroom vs what migrates to Capture One? I found that Capture One did a more complete job of importing Aperture libraries compared to Lightroom. I provided an article about it here on your site way back when.

I haven’t compared it, because you already did! The transition to Capture One is definitely superior. But if you don’t want to use C1, then…

I downloaded Aperture, I am using Big Sur, but an install page never came up. I never had a chance to put the app into my applications folder. The info box was referring me to the info page on how to merge Aperture library with Photos. Is this a viable alternative?

An install page for what never came up? There's no installer for Aperture; that just downloads from the App Store. And Retroactive also doesn't have an installer. Once you download it, the app is in a folder in your Downloads folder. It has instructions there on how to open it.

If you just try to open your Aperture library, then it will migrate to Photos, which is fine, if that's what you want to do. The point of this is to get Aperture running on Big Sur.

Bravo, Joseph! I had not heard of Retroactive and your post makes it crystal clear. I check your site every so often in faint hopes of changes, and there was your post. 

I had been staying with Mohave as I still use Aperture (for many reasons). Now I can last a few more years! Thank you so much.

Glad you found it! Keep in mind that this is not a guarantee of future compatibility… personally I'd be getting my library out of Aperture ASAP. But this is, at least, a lifeline.

In fact I'd go as far as saying that it's entirely possible any macOS Big Sur update could kill this, so be wary!

Hi Joseph,

REALLY a great tip. I stayed in Mojave because getting my images out of Aperture is along long process even with ApertureExporter. Now I just might not have to do that.

Incidentally, trying out Lightroom CC with a roll of scans first time, I really noticed how much easier things seem with trusty (and of course well known) Aperture.  Being able to have the freedom to do to this at leisure is huge!

R.

Thanks Rolf. I'm really enjoying Lightroom CC, to be honest. I do miss the advanced metadata view and search tools of Aperture though.

Well, I’m portrait and headshot photographer. For me, Aperture still the best raw converter for perfect skin tones. It’s simply the best.

If you own new cameras, which Aperture can’t open - the solution is to use DNG converter. 

In preference you have to change compatibility to custom - Backward Version DNG 1.3 + Uncompressed.

It will create DNG file bigger than original raw (I’m using Sony A7R4).

It’s no t for catalogs for sure, but to convert selected files for retouching is still the best for me.

 

Hi Vadim,

funny how different things can be: I currently do not own a digital camera, but all my scans of film (135, 120 and 4x5) reside in Aperture. Digital darkroom processing (my wet darkroom currently has 15°C – brrrrr) in Aperture is much easier and – in my experience – easier fine tuned than Lightroom CC. I suppose I could learn Photoshop and do even more to my images but that has hardly been necessary. The cataloging in Aperture is still superb.

Well, if things can go on a bit longer with Aperture I am quite happy indeed!

currently doing a clone prior to upgrading to Catalina!

R.

 

I'm glad that workflow is working for you, Vadim. Interesting that even with all the new developments, you still find Aperture's RAW conversion the best!

@PhotoJoseph

Yes, and used all other converters - RawPower, Capture, Lightroom…

Vadim, have you tried DxO PhotoLab? I do a lot of work with them, and I'd be curious to hear what you think of their RAW converter vs the others.

yes. And same no…

Wow, happy to see this and eager to hear your tips when making that migration to Lightroom. Am I understanding that that you are migrating to Lr (with mobile) not Lr Classic? I have decided to get my old Aperture Library finally migrated to Lr Classic (updated to Mojave 10.14.6 on my 2017 MacBook Pro) and I am prepping the library to clean it up before generating full size previews & then using Lr C importer. I do have a question about getting rid unconnected &  ”not found” images that show up when I search for any unconnected. (This is a managed library.)  I searched to track down and realize that they were deleted photos in an old iPhoto library after they had been imported to Aperture. They no longer show up in iPhoto but appear as “not there” black box with yellow triangle in Aperture. I don’t need them (107 images.) Can I delete them to get rid of them so they don’t confuse me later?  (I have viewed your cleaning up your Aperture Library series, although awhile back.)

Susan S

Yes, I'm moving to Lightroom CC, not Classic. I have a LOT to report; it's now complete! I will have to do a huge write-up on this. To answer your question, yes you can just delete those missing images. 

@PhotoJoseph

Thanks! I will do that for the 107 that I do not need. For the 3 that I do want but I found elsewhere, even though they show up as “not found” in Aperture„ is there a way to reconnect easily? I  found the same images in a folder of iPhone images that I had kept to import into Aperture. For some reason, those 3 show up as “not connected” and “not found”. (My library is Managed.) I just want to minimize confusion once I make the move into Lr C. 

Susan S

Hi Susan… so the three stat show up as “not connected”; what happens if you choose Locate Referenced Files, does it do anything? Since you do have the three originals, if the connection was originally to a managed file and Aperture has somehow lost that, it may be best to just reimport those three originals. You'd lose the editing you'd done, but it may not be worth the struggle to try to reconnect.

If it's critical to maintain the adjustments, you could dig into the package to see if you can find the original master files, and see if they are damaged and can just be replaced, but honestly I've never even done that. 

@PhotoJoseph

Thanks! Getting back to this… The adjustments are not critical. They are iphone photos, although images that I want to keep.

When I choose Locate Referened Files, it still shows “not found” for all three. In the box to the right I can see the path in RED print and the path says they are on my Desktop in a folder which no longer exists there. I do have the same three files in a labeled folder in my Pictures Folder along with others of the same time. It may be that the folder was moved from my Desktop to my Picture Folder. 

Can I delete these three from Aperture, choosing “Delete Original Images and all versions?” It won’t delete the same images residing in my Picures Folder, right?

If I delete those, and then continue with steps to  migrate my Aperture Library to LrC. I would probably wait until I have set up in Lr and import those 3 with others that of the same folder of iphone photos that are not yet in Aperture (or LrC.)

Thanks for your help. I want to get this in shape to proceed.

Susan S

Susan, as asked in my previous post, did you try Locate Referenced Files yet? That command is designed for exactly this; to reconnect broken links.

Regardless, you can safely delete in Aperture if you have the originals elsewhere. It doesn't know where the originals are; it has no way to delete them. And even if it did, it would only move photos to the Finder trash, not actually delete them from your system.

@PhotoJoseph
— Have you signed up for the mailing list?

Yes, I did try Locate Referenced Files. (Sorry, I thought I had indicated above.) It said “not found” but did show a path in “red” to where they no longer reside. I appreciate your replies. Helpful to get me to act and move on!

Susan S

I had a horrible experience migrating my Aperture library to Lightroom. It made a mess of things, it didn’t import everything and I’m still struggling to deal with it after having left LR behind and moved to CaptureOne.

CaptureOne is much more Aperture-like on the asset management side and works more intuitively for me. I have since migrated my Aperture library to CaptureOne with little problem.  I just need to deal with the missing couple years from when I was using LR before giving up, returning to Aperture and then discovering CaptureOne and moving there.

Capture One also does an excellent job importing Lightroom catalogs!
 
 

How timely. A chap from Steve Perry’s forum sent me your link. Grateful to him. A month ago I did a macOS Big Sur upgrade not knowing that my Aperture not supported. Prior to doing this Apple website said Aperture upgrade required; it should have said Aperture NOT supported. After the oh Sh-t, now what! Short version, I had long road back to macOS Sierra on my MacPro. That hidden file in Big Sur prevented reformatting HD to Mac Journaled. Found cure tho through a chap on uTube stepping through backward migration process. I fortunately had my system backed up using CCC (Carbon Copy Cloner). I too also have a iMac frozen in time with Aperture on it. Also like you, I don’t want to be held further hostage by Apple so all my 27K photos going to LrC. Look forward to seeing your documented process. Not sure if I should migrate Aperture Previews or let LrC rebuild them?

 

I will answer all of your questions soon. My migration of nearly 200,000 images from Aperture to Photos / Lightroom Classic / Lightroom CC is complete and better than expected. I'm working on a full report.

Aperture is running on my MacBook Pro on Catalina with the help of Retroactive.

Big problem when I start old Aperture Library  when I click on some thumbnails they turn black and I get message that aperture does not support this file type.

what is happening, it happens with half of my 30,000 photos.  can I do something to fix that.

Any suggestions would be helpful

wrv

I saw this on a couple of my images but after a relaunch that went away. I’d suggest reaching out to the Retroactive folks to see what they say, as you’re definitely not the only one seeing this. Maybe they have a solution. 

@PhotoJoseph

Joseph,

I have three Aperture libraries, 52GB, 189GB and 155GB, should I merge them into one Aperture library before exporting them to Apple Photos as you suggested to get the photos out of Aperture due an unknown future.

Thanks, John
