Mail 11 (High Sierra): mail attachments "downloading" but never actually download

I see there is an OS update -- 10.13.4. Has anyone here installed it and is there any chance it addresses this bug? I did not see anything about Mail in the update description, but one can dream, no?

Hi I have the downloading issue and my optimise isn't on for Mail

and I still have this problem,

I have 'rebuilt' the mailbox, and on one occasion it seemed to

work better downloading (and sending) attachments

but it isn't working again

... I wish never to ""upgrade"" again

I'm having this problem also but I'm not understanding the rules solution. It happens on most attachments and when I restart Mail, I am able to open them again but after a while (sometimes less than 10-15 minutes) they go back to perma-loading status. I only have a handful of rules and they are to pull messages out of the inbox so the messages I am seeing have not been moved. Is the issue just that they are being run through a filter at all? Does this apply to all rules or only rules that were created prior to the update? If it applies to all rules, does this mean the only solution is to use no rules ever?

Isn't it disheartening that, 6 months later, Apple has not bothered to fix this issue. I installed High Sierra 3 days ago, and I am not able to download any attachment whatsoever. File/Save Attachment does not work. I will not be installing any updates form Apple whether on my iPhone, iPad or iMacs in the future - that is what I have been hearing as well; not just my conclusion.

I have typically have just upgraded my Macs with each new OS, and I have not experienced a lot or mail problems before this one. The only other issue I have had is with unreliable search results, not finding emails that I know are there and a search should have located. This issue has been ongoing for several years.

However, because of some other wanky issues I was having, I think due to trying to run Windows with Parallels, I decided to do a clean OS install with High Sierra, and migrate my data over manually. Everything was fine initially, but this problem started showing up after I did the 10.13.3 incremental upgrades in early February.

I have to agree with several other posters that this is a major issue and one that Apple should fix sooner rather than later.

You have for a while and it depends upon these settings for the file to download .

You can click on apple logo > About this Mac > Manage > click on mail on the left side bar if you see this option dont automatically download attachments .

What are you talking about? Where is "apple logo > About this Mac > Manage >"? Manage does not appear in About this Mac, perhaps someplace else?

It's actually "apple logo > About this Mac > Storage > Manage >", but that does not solve my problem. I use only a few rules (colorcoding of important emails) and I have huge problems with attachments that does not download. I now use Thunderbird to download important attachments without any hassle.

THIS is the answer that worked for me! Thank you, I would have never taken this path to figure out the issue. (For the record I have no mail rules set up, so the above answers I knew would not solve my issue).

I have this problem too, but not only for some of my emails. When I access my emails via webmail (through my web host) rather than Mac Mail it works fine, so it's obviously a Mac Mail specific problem.

I also don't have my emails getting forwarded to different folders - they're just coming into my main email account folder. Would love a solution asap!!!

I wanted to try your solution since I do not have any rules set up but have this problem since upgrading to high sierra but do not have the option "Manage" under About this Mac. Not sure where to manage Mail... Thank you.

My Rules stopped working completely, and two Apple support people could not figure it out, told me to upgrade to Mojave. Rules started working again, but my attachments are mostly lost in transit. Unrecoverable, I have to get clients to email again... I'm trying the workaround with the Rule to not move emails with attachments, but that's not a fix. I can't believe this is still happening in Mojave.

Hi! I have the problem on Mojave. Didn't have it on El Capitan. It is from some of my contacts that I before the upgrade didn't have any problems with and the attachments do get to my mail provider but not to my computer. It is not always all attachments in a letter. It can be just some of them. I suspect it can be the size of the attachment that hinders its downloading. Nothing I can change though. I only have one mail provider.

I have well over 100 rules that I set up to move emails (of those I care to archive locally) from my Gmail account to permanent storage on my Mac. Even though the rules do a "move", it does not actually remove the original email from the Gmail account/server. When I open Mail, I access my recent Gmail from the actual account, so the attachments display and open as expected. After reading the Gmail emails, I delete them, knowing there is a copy stored on my Mac (again, of those I care to archive locally). I never ever noticed until a few days ago that the "copies" moved to my Mac have useless attachments. I have gone back to check, and I have many hundreds of emails that I thought were good, but have unless attachments. This is unconscionable, especially from Apple. I feel sick to my stomach to think of the photos and other documents I thought I could retrieve that are lost forever. What an eye-opener. My current Mac is my 10th or so, but I now think it needs to me my last. BTW - I have tried changing the rules to "copy" instead of "move", but the results are the same.

This answer completely disregards the real problem, which many users articulate in their responses here. Restarting mail or your Mac is not going to solve this. Please, someone at Apple acknowledge THIS IS A BUG, not user error, and it is still happening in Mojave.

I upgraded to Mojave partly for the improved security and privacy of Mail. Normally I wait a while before jumping on to a new system upgrade. And it's freakin' useless to me, because I cannot use rules without suddenly being denied access to my email attachments! What an utter crock. I'm going to go waste my time researching, downloading, and buying another email client now, preferably from a company that cares about its customers -- some of whom have been throwing enormous amounts of our cash at Apple since 1987!

Wouldn't it be nice if Apple acknowledged this horrible bug and their role in losing you your photos? It's a serious loss. I'm sorry they are not responding to you here or taking you seriously, and I'm sorry you lost your attachments.
