Sharing Lightroom catalog/database between Mac an PC

I have Photoshop Lightroom 2.4 for Windows. All my photos and Ligthroom catalog/database are located on a networked external drive. I am thinking about getting Lightroom for my new MacBook Pro, however I need to know first if I can access and modify Lightroom catalog/database located on that drive from both Mac and PC.
In other words, say, I am working in Lightroom on PC, adding and editing pictures one day. Then the next day I want to continue the work from my Mac. Can this be done? Do both operating systems use the same Lightroom catalog/database format?
Cheers,
RJ Czajkowski

John,
Thank you for your reply.
When I said networked drive, I meant a 1TB WD MyBook external drive, formatted to FAT32 and attached through a USB hub to 1TB Time Capsule. It is accessible from both my desktop PC (through Ethernet cable) and from my MacBook Pro (through Wi-Fi). All Lightroom data (catalog, previews, etc.) and all photos are on that drive.
Since both systems can access this drive, I assume this arrangement should work with what I want to do.
Cheers,
RJ Czajkowski

Shared Lightroom catalog with Mac OS X Lion

I keep my Lightroom catalog on my Macbook Pro so I have access to my pictures while travelling. But for editing, I use a desktop PC running Lightroom on Windows 7 on the same catalog. My process for doing this is:
On the Mac, enable SMB sharing.
On Windows, mount the SMB share.
On Windows, use "subst" to map the SMB share to a new drive root.
(This avoids Lightroom's spurious error about not supporting network volumes.)
On Windows, launch Lightroom and open the catalog on the mapped drive.
This worked in Snow Leopard. But after upgrading to Lion, Step 4 gives me an error:
Lightroom cannot use the catalog named "Lightroom 3 catalog" because it is not writable and cannot be opened.
This could be caused by incorrect permissions or because another Lightroom application is using the catalog. You may try to correct the problem or you may select a different catalog.
Permissions seem OK: I can edit the catalog and the Previews.lrdata folder in Windows Explorer. And I see no stray .lrcat.lock file that might prevent it from opening the catalog.
The Mac version of Lightroom can open the catalog just fine, so I suspect Lion's new SMB implementation broke this somehow.
Has anyone got a shared Lion -> Windows catalog to work?

OK, I found a solution. The following page describes how to manually install an SMB implementation (Samba) that actually works. It requires installing Xcode from the App Store, installing MacPorts, and some command-line tinkering to configure Samba:

Once you've done that , follow the instructions in this post to create launchd entries that will start Samba at boot time:

While I can now access my LR library again from Windows, this is just the latest in a series of annoying bugs with OS X Lion. I am not a happy camper— but I'll save that for the Apple forums.

Shared Lightroom Catalog???

I use Lightroom exclusively for my photos.   I initially used it with my desktop Mac (PowerPC G5) and then started using it also on my laptop (Macbook Pro). Both computers have all photos on external drives. There is a separate Lightroom catalog on each computer corresponding to each computer with it's individual external drive.   You can imagine my problem now, I'm sure. I have, effectively, TWO Lightroom catalogs, each with unique images, but also I've copied some photos over between them. The problem is growing exponentially.
Here's what I'd LIKE to do.   I'd like to install a shared NAS drive (perhaps an Apple Time Capsule drive) on my central hub in my house (my whole house is wired for Ethernet so that's not a problem), then put all photos on that single hub, thereby using a single Lightroom catalog and with it's images from either computer. If I have to travel somewhere and take some photos with me, I can deal with that because that it is typically the exception, not the rule.
Has anyone tried to do this?   I don't need to nor expect to hit the shared catalog from both computers at the same time. I'll be using one or the other, but not both. But I'd like to bring these two environments together.
I'd love some insight from forum members who've attacked this problem and solved it. I just don't know if Lightroom will allow the catalog to be on a shared drive, thus accessed by either computer.    If it will, then I imagine the work I need to do is:
1)     create a large shared NAS drive.
2)     copy all images to that drive.
3)     pick one of the two Lightroom catalogs and make that the master and somehow point it to the NAS drive.
4)     import the remainder of the photos on the NAS drive to Lightroom.
5)     make sure that both computers reference the Lightroom catalog on the NAS drive.
or maybe not. Maybe there's a better way. I'd like your input.
if this won't work, then has anyone successfully merged two Lightroom catalogs together.   One of my catalogs has about 80,000 images, and the other about 35,000 images.   At least 50% of all images are keyworded and I'd really hate to lose my keywords and collections that I've created.
anyway, insight is welcome. Tell me if I'm nuts too.
Thanks in advance.
Dennis

The closest think to this that will work is to put all the images on a large Firewire 800 drive with the LR catalog on the same drive, possibly in another partition. And alternately plug the drive into one machin or the other.
It is Networked drives where one can't put a Catalog, as John says.

How can I sync Mail database between MAC computers without using IMAP

All, I know this has been asked several times in several forums but I wish to ask it again with a slight twist. The normal question is can I sync Apple mail database (folders) between two MAC computers. The answer is always use IMAP, but unfortunately IMAP is limited on space to store historical emails. I keep mailboxes (on_my_mac) with thousands of emails and attachments that take up a massive amount of space, well beyond any IMAP server allowances. I keep these in order to search conversations that span over many months and sometimes years.
I use GoodSync to sync my normal folders from my MAC Book Pro and my Mac Pro desktop so that I can have the same information (in real time) when working from home on my big machine or at the office using the laptop. This is great except I can not sync the email. I use Outlook 2011 but would prefer to use apple mail if I can sync the two computers (Sync'ing Outlook 2011 is even more impossible).
I also do not want to start and stop my email clients to make this happen and worry about which MAC is running mail and what direction to copy the entire folder structure just to have to follow that up with a new re-build of the index.
Has anyone came up with a viable solution this this problem. Also keep in mind the amount of data - Cloud based solutions are dependent on Internet connection speed (days of initial transfer time and hours to sync) and if I am on my laptop without internet connection, say on an airplane, I would be out of luck so I need the information local on each computer.
Hopefully someone has some ideas, or maybe Apple can take a request for enhancement to Mail to support syncing multiple computers.

I assume that this is a POP system then.
There is no reliable method of syncing the Mail database between 2 Macs. Just how many Gigabytes of Mail do you have?

Importing into lightroom catalog on a mac

I just moved my lightroom catalog on an external drive to a mac from a pc. I got the entire catalog moved with no issues or problems except for this. When I try to import new photos i get a message saying that the file cannont be read and that the files were not imported. Has anyone else run into this issue while using a mac? Thanks for any help

How did you format the external drive? It needs to be FAT32 if you want it to be able to be read and written by both PC and Mac. Sometimes when LR says "cannot be read" it also or instead means "cannot be written".

What format should I made a shared external hard drive between Mac and bootcamp?

We have a small office running both macs and windows 7 on macs in bootcamp.
Currently we have 1 "master computer" which is a mac that stores all the data formatted in mac os extended (journaled). But we are always having rights issues with that and if that users machine is off, or having network problems we loose access.
The proposal is to get a new router with USB port and have a networked disk on where all the shared files are stored. The question is, what should the disk be formatted to?
As I have said the mac machines run bootcamp with 1 employee perminantly on windows 7. His hard drive is NTSC. As a side note I don't understand How can he open the networked shared files from the master mac!?
Ideally we want to search the folder for its contents from both mac and PC and I think this won't be possible if it is FAT32 formatted.
1 machine is the master mac
another is runs both mac and boot camp occasionaly.
3rd machine runs bootcamp constantly.
all macs are Lion 10.7.5
all bootcamp is windows 7.
we are in the uk
router is also our internet connection
we don't want an expensive server if we can help it.
Suggestions?

Extfat or fat16bit is just poor Mans fat32 where you get more then 8 chars filenames but not support for large volumens

Sharing One iPhoto Database Between Two Accounts

Below is a reply to a question I have regarding sharing photos with my wife on the same Mac. I would like for us both to able to upload, edit, and use photos from the same iPhoto database. Do all of the buggaboos listed in the reply below still apply?
Thanks,

For iPhoto 09 (version 8.0.2) and later:
What you mean by 'share'.
If you want the other user to be able to see the pics, but not add to, change or alter your library, then enable Sharing in your iPhoto (Preferences -> Sharing), leave iPhoto running and use Fast User Switching to open the other account. In that account, enable 'Look For Shared Libraries'. Your Library will appear in the other source pane.
Any user can drag a pic from the Shared Library to their own in the iPhoto Window.
Remember iPhoto must be running in both accounts for this to work.
If you want the other user to have the same access to the library as you: to be able to add, edit, organise, keyword etc.
Quit iPhoto in both accounts. Move the Library to the Users / Shared Folder
(You can also use an external HD set to ignore permissions, a Disk Image or even partition your Hard Disk.)
In each account in turn: Double click on the Library to open it. (You may be asked to repair the Library Permissions.) From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
However, there is a catch with this system and it is a significant one. iPhoto is not a multi-user app., it does not have the code to negotiate two users simultaneously writing to the database, and trying will cause db corruption. So only one user at a time, and back up, back up back up.

Sharing iPhoto '09 library between Mac OS X user accounts

Hi,
I'm brand new to the Mac world, so forgive the new user question on something that is probably obvious to all.
I've set up my new iMac for both my wife and I to access on two separate accounts. I've loaded our photos from my PC to my iPhoto program on my account. How can I get my wifes account to see the same photos? Do I have to load them on her account also?
Thanks for any help you can offer!

Sharing my mp3 folder between Mac and PC partitions

Hello,
I'm a Mac newbie considering Bootcamp on a new MacBook Pro. I'm wondering what's the best way to share a folder of mp3's (about 10 GB) between my Mac and Windows partitions. I read that Fat32 partitions can be shared but they are very wasteful of disk space. What's the alternative and is it reliable? Thanks in advance!

I use MacDrive to enable Windows to see the Mac partition. Then you can tell iTunes not to copy the songs when added. I think you can even copy the iTunes Music Library.xml from the mac side

How to turn off sharing of network settings between Mac and iPhone?

There are a number of wireless networks available around where I work. Whenever my Mac connects to one, so does my iPhone. When I tell my iPhone to forget the network, my Mac does as well. How can I turn off this behavior?

It's probably being caused by using iCloud keychain, which syncs passwords for wifi networks between your devices/Macs. You would have to stop using this feature to prevent stored and removed wifi network passwords from syncing between them.

Sharing and commenting pics between Mac and PC

I am looking for a software solution for this business problem. My customer needs to go thru thousands of small photos files, divide them into categories, give them rankings, comment them. I have the original files on my Mac, I can do the same dividing, ranking, etc. So he can send me his list of comments and categories and me in return.
Here are the questions: What is the best software for my customer’s PC / Mac (I never know what computer my client has) to allow this exchange? I am working with Bridge because it feeds so well into Photoshop and inDesign. But I believe one cannot buy a stand alone Bridge. And even if, the problem starts already here. When I send a file I worked on in Bridge from my iMac to my MacBook, identical set-ups, only the star-ranking survives the transport. The colour category is gone and the text I put into the meta data as well.
When I send an iPhoto file between iMac and MacBook, the stars are gone, but a comment in the meta data survived. And then there is Aperture which I haven’t tried. All very unsatisfactory.
Thanks for your help

How to fix Lightroom 5.6 crashing when backing up catalog database (external AND local backup) - Mac 10.9.5

How to fix Lightroom 5.6 from crashing when backing up catalog database (external AND local backup) - Mac 10.9.5
It starts to cue and within 3-4 seconds, the program just crashes hard. As stated, I tried it on local hard drive and external. Same result...
In the destination backup folder, it will copy over one folder, no images.
Thanks ahead of time.

I try to drag a photo folder into lightroom 4 on my MAC, lightroom fails to open and a 'Corrupt Catalog Detected' screen pops up. Clicking on 'repair catalog' does not work either. Any suggestions?

I'll have to get a better instructor on deleting the preferences since when I've doen it in the past nothing is there when I open LR the catalog is gone. I assumed that was what was supposed to happen so I start importing all over again. But that is a different issue...
The problem has been happening since at least the beta of 3 came out and I saw other posts back then saying they had similar issues but I assume it was a beta thing... But since the full version came out and through each incremental change I haven't seen an improvement. If anything it has gotten a little worse with time.
I have to try to be careful to not be in a hurry and start clicking around in the catalog as it seems fragile until it has cataloged all the photos in the library. When starting you will see the numbers populate the folders very slowly and I try not to click on a folder that hasn't had the number of photos pop up yet. Also draging the slider down to see more of the cataloge can have the same affect and crash the system.
I wish I had more to go on.. I believe it may be a resources issue but as I went from 3-4 Gig I thought it would get better. I don't have big programs running but did have outlook and word running in the background along with firefox and chrome.
And yes it only happens on this HP desktop (it's 2+ yrs old) and may be showing it's age a bit. My laptop which has less resources doesn't have the issue.. I have them sharing the catalog. (not at the same time) just when I'm working in other places in the house.

Home Sharing between Mac and PC

So I have Home Sharing enabled on both my Mac and PC, and signed into both with the same apple ID.
From my pc, i have installed the latest version of Itunes, and on my mac I have the latest version of Itunes.
I can access my library on my mac from the PC, but I cannot see any of the things located below.
When prompted, enter your Apple ID and password.Note: Be sure to use the same Apple ID when enabling Home Sharing on all computers you intend to share with.
Click Turn On Home Sharing.
Use the above steps to enable Home Sharing on additional computers on your home network.
Setting up Automatic Transfer
Automatic Transfer can transfer your newly-purchased apps, books, music, TV shows, and movie purchases to your other computers set up for Home Sharing.To automatically transfer content between computers, click the Settings button in the lower-right while viewing a Home Share and select which content to transfer. Automatic transfer of iTunes Store content is off by default.
Note: The Settings and Import button aren't present if you're using Music Sharing, which is different from Home Sharing.
Automatic transfer applies to new purchases from the iTunes Store whenever they are made. However, updates aren't transferred (such as those from the App Store).
Automatic transfer only applies to iTunes Store content you purchase or download after enabling Home Sharing.
Previously downloaded or non-iTunes Store content can only be manually transferred. It may be necessary to authorize iTunes Store content for playback on other computers.
Audiobooks purchased through the iTunes Store can be automatically or manually transferred.
Home Sharing can't transfer or stream audiobook content purchased from Audible.com. SeeAudible.com for assistance in using their content on multiple computers.
In addition, rentals from the iTunes Store can't be streamed or transferred to another computer using Home Sharing.
Home Sharing tips
The best way to avoid duplication is to use the Show menu located in the lower-left corner. Choose "Items not in my library" before transferring any content.
I do not have a drop down menu in the Home Sharing window, and also cannot choose items not in my library.
MY question is, how do I copy my purchases from Itunes from my mac to my pc????
Step by step please.

Hi clissmann,
It sounds like you simply wish to have your purchases on both your Mac and your PC. You can accomplish this by accessing your past purchases using the information in the following article:
Download past purchases - Apple Support

Take care, and thanks for visiting the Apple Support Communities.
