Switch Catalog from Windows to Mac
Hi Folks,
I have an issue with the switching between a Windows machine and a Mac:
I generated a catalog with thausands of files on an external hard drive in Windows.
It took hours to calculate all the previews, but everything is fine.
I now open this catalog with a Mac.
Of course I have do locate the external hard drive, because the Mac do not understand the drive Name "E", "F" and so on.
Capture One will Display all the previews, but the thumbnails are gone.
I have to force Capture One to Display all the Pictures of the Catalog to Regenerate the thumbnails, wich is very time expensive when the Catalog contains thausands of Pictures.
Is there any way to recalculate the thumbnails automatically without recalculating all the previews?
Thanks and best regards

It is strange that after your move from Windows to Mac, and after relocating the images, you have the previews but not the thumbnails. You could ask support whether this is as designed.
I do not have an alternative route for your migration workflow.0 -
Dear Paul,
thank you for your swift answer.
I would like to add the following information:
I copied the whole catalog from the PC to the internal HD of the Mac (size over 100 GB).
Only after the relocate of the files the thumbnails will be read from the external HD.
(you can hear the disk working accordingly)
Offline you only get the information about the format if you click on the empty preview Image.
(corresponding to the dashed white line)
The previews, on the other hand, were always visible
Best regards

Hi Thomas,
I assumed already what you described. The point is that the catalog contains both the previews and the thumbnails. After the transfer to the Mac, both previews and thumbnails should be available and the images in an offline state. That is the whole concept of the catalog: even when disconnected from the source you can browse and edit the images.
It seems - just a wild guess - that the previews are linked differently in the database than the thumbnails.0 -

The only one way I know, is to change some database entries manually. I do this since 2-3 Years, without any issues but I can't give you any guaranty for success!0 -
There is something inherently wrong with the relocation of offline disks/folders etc. in CO1. I have been involved in a support case, where these problems were acknowledged. Without going into the specifics, the database management when re-linking renamed or off-line disks/folders when migrating between the Windows and Mac platforms, falls apart and has me ending up with on-line disks/folders from which all images have disappeared (according to the CO1 app), which is fatal, because all the edits/layers are gone to the catalogue as well, meaning they are still in the catalogue, but the links to the originals have vanished, and the CO1 catalogue believes that the folders containing these images are empty, and is hopelessly showing question marks all over.
This goes back years and has never been fixed, so I guess the only sound advice is to avoid migrating between Windows and Mac when working with a CO1 catalogue.

I am having exactly the same issue now. Also migrated from Windows to Mac. There is a number of subfolders which show Question marks (still with all previous adjustments, just "offline"), when I locate them on the disk (which is the directory where they supposed to be anyway), they disappear from indexing forever. So they need to be re-imported while loosing all the adjustments.... this is crazy... 😭0 -
Hi Folks,
here are some observations I made during the migration:
On the first load of a Windows Catalog in the Mac, C1 choose for the missing HD the internal Mac HD and shows it as online.
When you now do a verification of the catalog C1 will chrash and the catalog file will be corrupted.
Sometimes C1 randomly splits the folders between several different hard disks.
The order in which the folders are now relocated is important here.
Once the relocation is done it is important to perform a new verification.
Some critical points are special characters used in the folder names. Folder names with special characters can get problematic. With a verification this is mostly fixed.
Greetings

Yes and this is only possible with the procedure I mentioned above. Or you move all pictures "INTO" catalogue0 -

I assume the method you mentioned is to modify the DB. If so would you be able to provide a quick how-to?
I would just need to know which file to open and with what program. I would assume, after that, you just need to provide a new absolute paths, which I hope I should be able to locate easily.0 -

You are right about the random splitting up of folders between different hard drives (different paths actually, the disks are physically the same one disk, but is shown with two different paths to that disk)
Verification will not help when a folder is properly relocated in the catalogue files panel, but CO1 somehow loses the notion that there are actually catalogue images in the re-linked folder, that show up "off-line" in the catalogue files panel, and subsequently there is no way in the world to relink the off-line images (with layers and adjustments) to their originals other than manually navigating to the original image one by one. Let's assume that that is not a viable solution for folders with hundres of images, especially if you have to do it all again after the next migration between platforms.
My only safe workaround for this workflow damaging problem arising (I assume) from incorrectly written database management (Lightroom is fully free of this kind of workflow damaging behavior):
1.) create the original catalogue on a Windows PC, NOT on a Mac.
2.) ONLY add new folders and import new images into the catalogue on a Windows PC.
3.) DON'T rename catalogue folders after adding them to the referenced catalogue files and folders panel, especially if they contain images
4.) Only re-link (re-locate) individual folders when migrating from Mac to Windows and vica-versa, DON'T re-link or re-locate disks.
Following these four steps, I have been able to use a referenced CO1 catalogue, stored on a Samsung T5 external SSD, and safely re-link and re-locate off-line folders without losing the contained images.
I would say though, that it is about time Phase One fixed this workflow damaging bug in the database management, certainly with the arrival of super fast and super reliable external USB-C SSD's like the Samsung T5, that make it possible to use a portable external catalogue without any speed penalties. I filed the support case half a year ago.

After hours of struggle I managed to fix the issue (it seems) this was my scenario:
I migrated catalogue from Windows to Mac (Mojave). On both units I had C1 v12.
In my catalogue I have files stored on local drive as well as on my Nas.
I believe this was the part of the issue that migrated Capture doesn't know how to handle.
Becuase after moving the catalogue, I would have all subfolders listed as Offline, which normally is not a problem and could be found with "Locate..."
However for whatever reason, when try to locate folders from root directory it C1 would crash. I would restart it and try do the operation again, just learning after sometime that at this time the Catalogue was already corrupted and all the unallocated directories disappear as soon as I would run them through Locate.
How I fixed it:
1. I copied catalogue and Adjustments from Windows once more, replacing the one on Mac.
2. I run C1 pointing to freshly copied catalogue and I Locate first only the directories that I had on local harddrive, and then separately the ones that I had on the network drive. I realised that if you try to locate from root directory subfolders poiting to both network and local location this was causing crash of C1 and corruption of catalogue. To fix then I would need to repeat from step 1.
3. Keeping the split in locating between network and local drive made me go through without C1 crashing. After all was ok, I back up/verified catalogue and restarted C1. All seems to be in order. All the files, previews and adjustments are there.0 -

No problem if you can write the name of your catalog and exactly where are your photos under Windows and the paths by OSX.0 -
Hi RobiWan,
As mentioned above I managed to solve the problem with the fix I described above (so in a nutshell avoiding C1 crashing and corruption of the catalgoue), but perhaps someone else could use also your advice in case mine is not applicable?
