[Rikk Flohr: Photography]

If you save your catalog on an external drive or if you are tethering with Nikon products, please read before you update your Mac OS to Ventura (13.x)

When I load the picture onto my Mac and then I import it into Lightroom there is no problem. This can't be the solution, as I need the pictures on my external hard drive otherwise I'll use all my diskspace on my Mac.

This is a known issue.

The basic problem is that you are connecting a USB hard drive through a hub.  If your drive is USB - C, try connecting it directly to the mini.  USB-A is the slowest form transfer you can use.  A direct connection is only 5 Mbps. Add a hub and you are constrained even further.  You don't say how large your catalog is, or how many photos you have.  You also don't specify your memory configuration.  All of these factors play into import speed.  You also don't tell us how you are importing the images (card reader - type of card, type of reader, how reader is connected, image format and size).  While there is a known and well-documented issue with LRC 12, Ventura, and external drives, you indicate your problem predates the install of either LRC 12 and Ventura.  I suggest your problem is everything external to your Mac.  You need to upgrade your harddrive to something much faster (minimally USB C, preferably Thunderbolt 3/4).  Ditto your card reader.

Thanks for your answers. I'm not using a USB-Hub, the WD 12 TB external hard drive is directly connected to the USB port of the Mac Mini M1 (not USB-C). Sorry, wrong explanation by myself. I have 8 GB RAM. I never had any Lightroom issues on the MacMini. They just came from nowhere some days ago. My catalog has around 400 photos. I have catalogs that are much larger and never had any issues. I export the photographs from the CF-Card to my external hard disk directly, rename it with "A better finder rename 11" and rate and select the photographs I want to edit with Photomechanic. Then I choose "Edit photos with > Lightroom" in Photomechanic when finally the import dialogue of Lightroom appears. I then import the photographs into Lightroom. As I said, I never had any issues on my Mac Mini with Lightroom. Once they are imported I can edit them without any problems and the export is pretty fast. It's just the import that now takes forever, even if it's just one file. If I copy the pictures on my MacMini, they import as fast as they did before the problems appeared. It's not a permanent solution as I have lots of photojobs with lots of files that I have to store on external hard drives.

After you've culled your images in Photomechanic, try exiting Photomechanic and just bring up Lightroom.  Import them directly without using PM as an intermediary.  If they import faster, your problem may be that having both PM and LR open at the same time may now be too much RAM usage and a lot of page swapping.

Nach dem aktuellen Lightroom Classic Update wird der alte Katalog derart zerstört, dass eine Fehlermeldung: Failed to initialize pixelmask storage, Dateiname-v12.ircat.data erzeugt. Eine weitere Nutzung ist nicht mehr möglich.

Apple MacBook Pro M1, Ventura-Betriebssystem

known bug, MACOS Ventura and catalog on external drive.

Workaround might be to move catalog to internal drive

Fix is to wait for Adobe to update v12

HELP! Yesterday my Macbook Pro loaded the new OS- Ventura. Now when I attempt to open Lightroom Classic I get the following dialog box error:

 

[Patrick26804035t1lz]

Depuis l'installation de MacOS 13 Ventura je n'arrive plus à ouvrir Lightroom Classic

Le message d'erreur est :

Échec de l'initialisation du stockage du masque de pixels

Echec de la création du fichier de verrouillage dans le dossier : Canada 2022-v12.Ircat-data.

Le processus ne peut pas accéder au dossier car il est utilisé par un autre processus.

[francinardaux]

As soon as I try to open Lightroom Classic this message comes out:

Impossible to initialize the mask archive based on pixels.

...???? what does it mean and why?

Atualização Lightroom 2023 com erro ? Alguem sabe como corrigir esse erro?

[brucekorb]

A fuzzy notion idea that gets updated regularly would be good: tomorrow? next week? next month? next year?

LrC start niet op. Op het scherm verschijnt de melding dat de pixelmaskeropslag niet kan worden geïnitialiseerd. Er kan geen vergrendelingsbestand worden gemaakt in de map (de naam van mijn catalogus).lrcat-data. Het lukt mij niet dit op te lossen.

This is a known problem. Please take a look here: https://community.adobe.com/t5/lightroom-classic-discussions/p-error-message-failed-to-initialize-pi...

[JohanElzenga]

There is an update (12.0.1) today that should deal with this.

[justv98738661]

Thank you! Is it an update for the Mac or for Lightroom?

[mcder4]

I recently bought a tether cable for my Nikon D850. It works fine tethering in Lightroom Classic on my PC. My MAC will not recognize the Nikon D850.  Lightroom Classic is version is 12.0.1 and Ventura 13.0.1.

This is a known issue. https://community.adobe.com/t5/lightroom-classic-bugs/p-unable-to-import-from-direct-connected-nikon...Adobe has a bug open.

Hi, 

Since last week, I can't tether anymore with Lightroom classic with my Nikon D750. It was working perfectly before (with rosetta emulation mode) . I did update lightroom last week, though, and also my mac system (I am now under Ventura 13.0.1).

Any help? I have tried every single troubleshooting solution provided but nothing is working and I have to tether for work ASAP!

Thanks

Tethering is not working on lightroom using Macbook pro M1 Ventura 13.0.1. 

[Ian Lyons]

What camera make/model are you trying tether?

[Angelique Photo]

D850 

Just upgraded to the new MacBook Pro M1.

Iv always tethered to Lightroom when shooting with my last MacBook Pro Catalina. Workflow is quick & easy with tethered.
