I started my adventure with photography on a Samsung laptop with Windows, when buying which I was guided mainly by the parameters of what it has inside. Then I bought an external monitor and I struggled for several years until I realized that a TN matrix and a cheap IPS monitor are not the best set for working with photography. Although at that time I had an intel Core i7 processor (you know, the larger the “i” the better) 16GB of RAM and some fancy SSD from Samsung, which I bought to somehow it went. It was tolerable, but sometimes the system stated that 16GB of RAM is not enough and will close a program for me, at its discretion. I was sick of it.
Switching from PC to MAC while working on photos
The time has come for a serious decision. At first I thought that buying a laptop for 3000 zł + larger RAM and SSD, then I already have a demon of speed and performance. However, after testing and serious searching, I decided to switch to the MacBook Pro 15 from 2015
Apparently also i7, but instead of 2 is already the 4th generation, RAM the same and a small SSD 256GB but not SATA and already PCI-E, but the work on the Mac was much more pleasant. Nothing spilled out with the same amount of RAM, I did not have to format the disk, because the system had some problems and collected syf, and the feeling of this equipment and the quality of the matrix for those times, it was something that gave me joy from work. Today it already works on MacBook Pro 14 and I sincerely recommend!
Laptop for photo processing?
If you are wondering what laptop to buy for processing and what to look for, take a look at the entry that I have prepared on this topic.
Remember about backup!
Once I installed all the programs on the new computer, I still had to deal with moving the photos and the Lightroom catalog. Here you have to be careful not to make a mess. It is best to rip the contents of the entire drive to an external USB drive. If we are not sure what we will need, it is better to copy everything to an external drive, then successively transfer all files to bring our data and program settings to the state we had on the previous laptop.
At the moment, a decent 1TB SSD for USB 3.2 gen.2, which has transfers at the level of 1000MB / s and it is hard to damage it with shocks we will get for about PLN 500. Check out the Samsung T7 1TB . I use an older version of Samsung T5, which has a transfer rate of about 500MB / s, and you can work on it very quickly and even process photos. Losing a large number of photos and other files will not take you much time.
Where do you keep your photos?
Well, if we have all the photos in some folder that contains all the directories, then we can move it to a new computer and after moving the catalog indicate the location of the photos using the “Update folder location” option. If we have pictures on the NAS network drive, then we only need to indicate the path on the new computer. But let’s start by moving the Lightroom catalog, and we’ll come back to that at the end.
I have a separate share on the network drive (such a partition on NAS servers) called Urbanflavour, and in it everything is divided into years. On a laptop, it looks the same.
How do I transfer a Lightroom folder from PC to Mac?
Find a catalog
To move our directory, we must first determine its location, which is very simple. Either we already know where we created the catalog, or we can do it by opening Lightroom Classic and selecting from the menu:
- From the top menu we select: Lightroom Classic -> Catalog Settings
- Hot key: Options + Command + comma
In the Catalog Settings window, the first thing you will see is the General tab which starts with the Information section, and the first one is the path to your Lightroom catalog. Simply click Show and you can already see your catalog. In my case, the catalog string was
For me it is Location: /Volumes/UF/Catalogs/_LightroomCAT so I copy the _LightroomCAT directory.
Your directory may have a different name. By default, it’s just Lightroom and it’s in the /Users//Pictures/[wasza nazwa użytkownika]Lightroom button, but if you’ve created a directory yourself elsewhere, you’re doing the same.
Move key files
Before we start moving files. Close Lightroom Classic.
The most important thing we will care about and is located in the directory folder is a file with the .lrcat extension, and from the Lightroom Classic 11 version also a .lrcat-data file, which is equally important.
The Files with the ends Helper.lrdata, Previews.lrdata, Smart Previews.lrdata and Sync.lrdata are not that important, so nothing will happen if we do not move them. My catalog with thousands of photos from 10 years has about 2GB, but Previews and Smart Previews files can already take up several dozen GB – these are thumbnails and previews of photos that are created during catalog browsing and photo processing. Lightroom will rebuild the Previews files itself, and We can create Smart Previews ourselves.
In the folder we will also find a sub-folder called Backups, which creates backups of our directory according to a fixed schedule. To fire up the catalog in a new location we do not need copies, so we can delete them or leave them in their place.
I make such a copy once a month, because I also use TimeMachine anyway.
Settings files and presets
In the folder with the catalog there may also be a Lightroom Settings folder (if we have chosen so before), which contains most of our Lightroom settings and the most important – presets!
By default, however, it is:
In Windows – C:\users\<username>\appdata\roaming\Adobe\Camera Raw\Settings
On Mac – Macintosh HD/Users/<username>/Library/Application Support/Adobe/Camera Raw/Settings
If you use one directory, you could choose to save to the directory. This has its pros and cons (a separate entry will write about it). If you use this option, you need to move this folder so as not to lose your settings and presets.
If you check the “Store Presets with this catalog” option and have not used it so far, your settings will not be copied. So if you are already at the stage of moving the catalog to a new computer, click on “Show All Other Lightroom Presets” and copy this folder.
And if you want to keep all the settings in the folder with the folder, then you can check “Store Presets with this folder” and copy all the content to the path in the directory that Lightroom will create and you will get to it with the button also with the “Show All Other Lightroom Presets” button – see that this is already a path …/[wasz-katalog]/Lightroom Settings
And one more thing. If you use several directories, this may not be the most convenient solution for you, because the new catalog will not see presets associated with another directory.
Folder with presets
The presets themselves can be found exactly in the folder
Copy the directory to the new computer
You can copy the catalog to a new computer in any way on-line, using a memory card, pendrive or hard disk. I recommend a fast Samsung T7 SSD (successor to T5), which I received from my wife and I also keep an excess of photos on it. When cooperating with other photographers, it allows you to quickly transfer a large number of files, so you can also use such a portable SSD to transfer our photos from a laptop, because external SSDs already have similar capacities of 512GB to 2TB.
If we have a MacBook or another Mac, then we have one very fast SSD, so in terms of performance it does not matter what partition the disk is on. However, in terms of convenience and
security for working on photos, I recommend making a separate partition, or rather an APFS volume (volumes dynamically allocate space, so you do not need to determine their capacity in advance) and on it create a place for a directory, or directories, if you have several of them. In my opinion, this is a better solution than the default directory location in the macOS user directories.
For me it is the volume “UF”, in which I have a folder “Catalogs” and in it I put my main LR directory “_LightroomCAT” – /UF/Catalogs/_LightroomCAT. Previously, I had a directory directly on the volume “UF” in a folder called “LRCat” or something similar. It is important that the directory files are in a folder so that they do not mix with other files and folders. In my case, the only folder I created myself is “Plugins” where I put files for JPEGmini and Pic-Time plugins.
Once we copy the directory and Lightroom is installed, just double-click on the file with the extension .lrcat and a blue icon. We can open Lightroom Classic and select File -> Open Catalog. Now it’s all set.
If you haven’t moved the preview files, your photos may take a little longer to load at first. We can also generate Previews, 1:1 Previews or Smart Previews.
