I’m very sorry for the inconvenience this issue is causing. The Quicken Mac team is working on a fix, and it will be released very soon.

this sounds like a Quicken issue rather than Vanguard

Quicken Victoria

Hello! The fix for the issue with Vanguard has been released. Please try it now and let us know if you still experience any problems with this FI.

We truly appreciate your patience—thank you very much for your support!

Brad L Vandermoon

error continues to persist. my vanguard account are 401k accounts.

can you please describe the fix that was implemented?

Jon

No joy here either - problem persists even after a Retry.

Edit: Oh! Didn't realize I needed to download a Quicken update; thanks to @JohnV for pointing that out. It's working fine with 8.1.2.

JohnV

Works for me now! It's a software upgrade. 8.1.2 on Quicken Mac.

Brad L Vandermoon

after updating software, it is working1. thanks @JohnV !

can someone from quicken please describe the fix that was implemented?

GIWalt

Can someone let the rest of us know what happens if we manually downloaded the transactions during the down period? That is, are the same transactions duplicated so the duplicates need to be manually deleted or does Quicken/Vanguard somehow able to know the manually download transactions don't need to be added?

Works after upgrade, now, can someone fix the stock market 😆

Still broken for me. Second day. Hopefully there will be a quick fix. 🤣

When I launched Quicken Classic Mac this morning, there was an update available to Version 8.1.2 (Build 801.56902.100). This update acknowledged and solved the latest Vanguard syncing issue for me.

Quicken Victoria

It is great to hear that the latest Quicken Mac update has fixed the issue with Vanguard! Thank you very much for letting us know.

barryi

Working with new upgrade. Thanks for getting this fix out.

If you have one or more Vanguard accounts in Quicken Mac set up for Direct Connect, you should see a notice about upgrading to 8.1.2. If you disconnected your Vanguard account(s) during the outage, or switched to Quicken Connect, you may not see the announcement — but you can pull down the Quicken menu and select Check for Updates to get the 8.1.2 update (and then set you accounts up for Direct Connect again).

(Users who don't have Vanguard Direct Connect accounts have no reason to update to 8.1.2, because the only change is the fix of this issue for Vanguard Direct Connect users.)

Thanks for getting this issue resolved. All our Vanguard accounts are updating correctly now. While dealing with the errors I used the manual method of creating .QFX files, one for each account directly from Vanguard. I noticed that one account has a different acct# in the .QFX file than what it does via DirectConnect. Is that an issue to address with Quicken or Vanguard? I did in fact disconnect that one and reconnected it after the fix thinking that it was some old data stored in the Quicken connection files. That's when I noticed that DirectConnect is using an account number that was changed by Vanguard decades ago. Any ideas?

Quicken Victoria

@drmcnabb, The issue was due to changes that Vanguard rolled out, which broke the connection with Quicken Mac.

Thank you for confirming that it is working for you now!

Excellent, my connection worked too. I just wish the bottom line had been better news.

sajoslin

It appears to be fixed! I had a Quicken for Mac update this AM, and with a synch to Vanguard my accounts accurately updated as of 5 April 2025.

kenzo

I too am also still getting error 16503 when trying to download Vanguard transactions into Quicken Mac.

Even after prior posters said "it's fixed".

Was there some sort of special force-reset procedure you went through to re-conect?

GIWalt

I believe there is a new version of QMac so you need to update first.

Did you update your QMac installation to the latest version? The fix is in that.

cvaux

Thanks to the Quicken support and, probably, thanks to Vanguard support too.

• download and apply the update from Quicken (most important)
• change connections type to Direct Connect
• change to detailed view on the Direct Connect
• Re-synch
• Should be good to go - hopefully for more than a few weeks this time.

kenzo

Boatnmaniac You were absolutely right. That fixed it. It's odd in that usually, whenever there is a new Quicken release, it shows me a pop-up as soon as I launch Quicken, asking me if I want to install the update. But Quicken didn't do so for version 8.1.2 — I had to manually select "check for update". Thank you again for your wise guidance.

Boatnmaniac

@kenzo - You are welcome. Thanks for posting here that it worked for you.

FYI: I use QWin, not QMac, so I do not get those QMac version update notices at all. I've been following this thread and it was posted in here earlier that the version update fixes the issue….and it has been confirmed by many that it really does fix the issue.

@kenzo I believe it is currently showing the update notice only to users who have a Vanguard Direct Connect account. So if you switched to Quicken Connect, or disconnected your account, during the connectivity outage, that's why you didn't see the notice. I believe the developers were trying to spare all other Quicken Mac users from downloading and installing an update which contains only the fix to this specific Vanguard issue.

ONGOING 4/8/25

This issue remains ongoing and our teams continue to work toward a solution. No ETA or further details are available at this time, and this Alert will be updated once more information, updates, etc become available.

We apologize for any inconvenience and appreciate your patience.

Are people who have updated to Quicken Mac 8.1.2 still having trouble syncing their Vanguard accounts?

Are people who have updated to Quicken Mac 8.1.2 still having trouble syncing their Vanguard accounts?

@Pothole Damage The 8.1.2 update to Quicken Mac added a specific fix to work around the problem Vanguard created. All reports on this forum have been that Vanguard downloads are working properly for users with Vanguard Direct Connect accounts.

Pothole Damage

@jacobs I'm aware that Quicken said this issue was fixed with the April 4 update to version 8.1.2.

That's why today's post here from moderator @Quicken Jasmine confused me. She said, "This issue remains ongoing…"

Quicken Jasmine

Hello @Pothole Damage,

The ongoing message was in reference to Quicken for Windows users, Mac users can refer to the update previously provided by @Quicken Kristina. I have updated my response in the alert to reflect this.

I apologize for the confusion!
