QB for Mac 2019

I have the QB 2019 desktop version and want to access it on my second computer in another location.  Does the program on the first computer need to be closed in order to access and use it on the second one or can they both be open at the same time.  Only one user.

Thank you.




QB for Mac 2019



QB For Mac 2019 is not designed to be multi-user ready.  Also, keep in mind your company file would need to reside on a server or some computer that BOTH your machines have access to.


That being said, IF you put your company file on a NAS, or a server and both machines can access it then this might work.  The other option is to use remote software like RealVNC or Teamviewer or something similar to remote control the main computer from computer #2.

Good afternoon, 

My question does not relate to multi users.  According to the manual, QB for Mac 2019 can be used by one user on two computers.  My file is stored on iCloud, so I should be able to access it from my second computer.

I'm looking for advice as to whether I should close out of the program on computer 01 before accessing the same file on computer 02.

Greetings, Josienjoe.

Allow me to chime in for a moment and share some additional information about accessing your files in two different computers.


You can open your files in both computers. However, any modification made will not be saved or shown on both sides.

I’m really confused.  I purchased QB for Mac 2019 desktop based on the fact that it could legally be installed on two computers by the same user.  So are you saying that I can look at my file on the second computer but not do anything with it?

Hi there, @Anonymous.


I appreciate you coming back to us for additional support. Allow me to join this thread and clear this up for you.


Yes, you're correct. QuickBooks can be installed on two computers. However, any changes made on the other computer will not reflect on the other file. This feature is only for pulling up and viewing purposes. We don't recommend editing the same company file on different computers for it may result in some data issues.

Yes, with a single user license, you must be logged out of the file on the first computer before you can access the company file on the second computer.

I am intrigued by this as well.   I was about to purchase the 2019 for Mac for this specific reason.    I have 2016 on my laptop in the home office.    It is a larger laptop, and I would like to be able to travel with my smaller laptop.   I was hoping to do so and then access Quickbooks from the smaller laptop when traveling - - making changes and creating purchase orders and invoices, just like I would from the laptop in my office.   It sounded as though anything I did in Quickbooks would be saved on the cloud platform.     When getting back into the laptop in the office, all I would need to do is make sure I open the file from the cloud and all the changes / additions I made when traveling would show up.   Thus using two computers, one user, to access one quickbooks file.    Did I read this wrong when reviewing this on the Quickbooks site???

Welcome to the QuickBooks Community, ehaddock.


Thanks for considering in upgrading to QuickBooks for Mac 2019. I’d be delighted to point you in the right direction about accessing your QuickBooks file on another laptop.


Yes, you’re right. You can access the company file using two computers. All you have to do is share the file on your iCloud Drive.

If you haven’t set up iCloud yet, let’s go ahead and turn on the feature. Let me walk you through the steps.


  1. Choose the Apple menu, then select System Preferences.
  2. Click iCloud, then enter your Apple ID and password.
  3. Turn on the feature you want to use.

After completing the process, move your company file to the iCloud Drive. For more information about opening your file on different a computer, follow the steps in this article and proceed directly to the To share your company file section of page 24.

The information I provided should help you view your company information anywhere using a different laptop.

If there’s anything else I can help you with, reach out to me directly by posting a comment below. I’ll be right here to assist you further.

Thank you very much for your detailed response.    I have a question after reading through it.   You mention being able to access the company file from another computer.    I am hoping to not only access and see the information from another computer, but to be able to do work in the system and then the changes or additions to be made to the iCloud file.   Thus when opening quickbooks again when I am back in my home office, it would have the changes I made from the other computer.   Does that make sense???   It seems like there is a lot of confusion about that in the community groups and with customer service reps as well.

Thanks for coming back to this thread, ehaddock.

Let me provide some additional information on how the iCloud feature helps manage your business and company file.

You can share the files you've synced to iCloud with colleagues who have an Apple ID from either a Mac or an iPhone. They’ll be able to modify the file and the changes automatically sync to your devices.

For future reference, I’m also adding steps on how to share the iCloud Files. Let me guide you through the steps:


  1. Go to the Finder icon, then find the file you want to share.
  2. Click the company data to highlight it.
  3. Choose the Share button, then select Add People.
  4. Choose how you want to send the invitation, for example, mail, messages or via social media.
  5. Click Share.

The information I provided should get you pointed in the right direction.

Stay in touch if you have additional questions about QuickBooks. I'll be here to keep helping. Take care and have a wonderful day.

Am I hearing this thread right?  So, I'm in the process of purchasing QB 2019 Desktop for Mac and I am reading there is NO MULTI-USER feature with this version?  I have 3 users and I want to put QB data file on the NAS.  1) Does the program AND the data file need to be on the same system? or 2) Can I put the program on my iMac and have the data file reside on the NAS?


And does QB 2019 Desktop for Mac support MULTI-USER?


QB for Mac 2019

Hello Tamm_Kent,


Thank you for posting here in the Community. I'm here to lend a hand with any questions you may have with using multi-user in QuickBooks Desktop for Mac.


Our Mac version of QuickBooks supports the Multi-user mode for all users to access the file at the same time. If you need the steps on the setup, I'm adding them below:


  1. Open the Multiuser folder.
  2. Drag the QuickBooks Server icon to the Applications folder.
  3. If prompted, select Authenticate to modify the Applications folder.
  4. Enter the Admin username and password.
  5. Select OK.
  6. Launch QuickBooks and open your company file.
  7. Go to File, then select Enable Multi-user Mode to share your company file.

Here's a screenshot for your visual reference:




If you're using QuickBooks in multiuser mode and you have more than one license, you can use the feature. To know more on the recommended storage for the company file, It would be best to visit the support link on this:


Multiuser checklist: What you need to know before you start.


For your future reference, I'm also adding some helpful articles that I recommend below:


Feel free to get back to me if you have additional questions with setting up multi-user. The Community will be sure to get back to you.

Multiuser is still supported.  iCloud file sharing between two computers is also supported. You can work on one computer (say at work) and then pick up where you left off on a second (say at home). 


Here's a video describing it:

Not sure this is the right forum for this question, but I'll give it a shot. We have 2 licenses for QB for Mac 2019 and have 2 users who access the same file. We upgraded from and earlier version and put the file on dropbox. We started having problems in that both people could access the same file at the same time in single user mode with no warning to the other user. We thought this may be a dropbox problem so we copied the file to our local server, and when we tried to access at the same time is still allows it. WHY? The best thing about the previous versions were that only one person could access the file at a time, and therefore not screws up the accounting by entering simultaneous information not syncing.


QB for Mac 2019

Hi JohnA2,


Thanks for letting me know how it works after you've copied the file to local server.I get the points you're making when only one person will access the file at a time. 


We can try some troubleshooting with this, please check out this article and follow the solutions provided: Troubleshoot multi-user isues for QuickBooks Desktop for Mac.


If you're still getting the same result, I suggest reaching out to our Phone Support to check on how your file was being set up in QuickBooks. Here's the link: Click the Search for something else button. Then, enter your question.

If two people access a QB file on Dropbox at the same time Dropbox will make a copy of the file and give that to the 2nd user.  You will no longer be working on one file and there's no way to "merge" the changes. 

With 2019 it should detect that two writes are attempted and warn you but this is more tested with iCloud - Dropbox can change how it works, etc.  We strongly advise against doing this.


Same thing with a local server.  There used  to be a lock file that would block the 2nd access but now its supposed to be detected by the OS and reported back as a conflict.  In any event accessing a QuickBooks file over a local network is not advised as the network file sharing system can have issues with Apple's CoreData - something that Apple has documented and that involves locking mechanisms.  How bad this is depends on the network file sharing used.


The proper way to share a file among two users on a local network is via the Multiuser application. That will always work and the two can use the file at the same time.

This is not an answer to the question. I tried multiuser when it first came out way back when, it was a disaster, a REAL DISASTER. I'm going there again. With 2019 we lost the warning about there being another user with the file open. All I want is the warning back.
