macOS Ventura Apple Mail messages are blank / empty

What do you mean by 'move' it to a 'new' mailbox? I tried to drag/drop into another, existing, account's inbox in the desktop app. Only one of about 15 messages I tried was restored using this method.

Yes - I mean Drag/Drop. But you must move it back to the original account's inbox as well, THEN it shows up. So you must drag and drop the same e-mail twice, then it shows the contents. This has worked for me every time I've tried it.

Darn. That's what I tried. Really, I was about 2 for 20 on getting that to work.

I'm ops-checking Outlook for Mac now. For me, the No Content messages are a show-stopper in Apple Mail.

Thanks for the tip.

So many problems with VENTURA 13.2.1 on both MAC MINI pro M2 and MAX M1 Mac Studio

Garageband

Mail

external hard drives

i've just spent over 10 grand on APPLE products. will have to wait for fixes...

Update. I had the "show remote images" set to off in Outlook which is why I thought it had no/little content. I reinstalled MS Outlook and no issue with the mail content. I tested Outlook side by side with Apple Mail and when I got an email with no content on Apple Mail it showed full content in MS Outlook. I guess I can assume this is an Apple mail issue only. I may stay with outlook unless Apple can fix this issue.

Same thing is happening to me & it is an email coming from AppleOne! Go figure. I get so frustrated with these glitches. There is also a message in the header that says "Security: Digitally Certified" & when I click on learn more it talks about BIMI??? So bloody annoying...

Issue: “mail has no content”

This is not the easiest fix but the only one that worked for me (should work for either Monterey or Ventura):

 After trying every suggestion, I finally (as a last resort) booted into recovery, erased my drive and reinstalled the OS (Monterey, 12.6.3).  I then migrated my files, apps, etc. from my TM backup.  This fixed the mail issue.  I tested this for the last 7 days (150 emails) and the mail is rock solid.  I’m guessing somewhere along the way after some OS security update the issue started. 

NOTE:  Before reinstalling the OS I tried updating to Ventura but the issue continued.  I also tried just reinstalling the OS not touching the data volume but that did not work.  I had to erase the drive and start over.

That is a marvelous idea. I should have thought of this myself :-). In the past, I used to do this regularly. But somehow after upgrading to Ventura, I haven't found the time to install the related Onyx version.

I ran Onyx maintenance, and things have been stable now for a while, without black/white screens and missing buttons. Though, I did get a purple screen once, while presenting with Keynote (restarting Keynote fixed that). Let's hope this is a permanent solution.

A friend of mine mentioned that he solved this problem by aggressively clearing caches and deleting unneeded application files. That took him two days. So, I didn't fancy going in that direction. Probably, Onyx does a similar thing, but then automatically.

Running Onyx fixes the problem temporarily for me but it comes back.

I've discovered that relaunching the Finder from  > Force Quit also fixes it temporarily.

When the problem with blank e-mail occurs I have also noticed that concurrently when entering something in the search field in Safari and pressing Return, nothing happens. Again re-launching the Finder fixes this temporarily for me . . .

I have also found that it has something to do with servers.....the faster my connection, the less it happens. Really strange. I've run Onyx again and yes, it does recur. Haven't had the Safari problem but I'm still on Monterey.

Unfortunately, I can also confirm that running Onyx is only a temporary fix.

I now also experienced "the" problem when doing a Quick Look of some documents, in particular some Excel sheets . The previews were all black. I will try to relaunch the finder next time to see whether that helps (if only temporarily).

I tried Safe Boot for about 20 minutes and the problem did not re-appear in that time. However, the problem does not always appear very quickly anyway. I had to re-boot to normal operation as things I require are not available in Safe Boot mode.

I have now reported the issue to Apple via Feedback Assistant and ask everyone else who is seeing this problem to do so as well. The more people report a problem, the more attention it may get. Apple Feedback Assistant is here: https://feedbackassistant.apple.com/

Just to confirm, the problem remains after the macOS 13.5 update. Possibly related to the problem, I am also seeing Safari become unresponsive occasionally.

The machine is only a few weeks old with a factory installation. I don't have time at the moment to do a full erase and install.

I eventually spoke to Apple Support and the techie also suggested doing an erase and reinstall of macOS as, in addition to the glitches with Mail and Safari, the Data volume on my nearly new Mini M2 Pro had become slightly corrupted.

I've now had the opportunity to do that and then restored everything from a Time Machine backup but unfortunately all that effort has not fixed the problem with Mail and I'm still occasionally seeing the issue with Safari where entering an address and pressing Return does nothing. (Quitting Safari and re-starting it with the Shift key pressed usually, but not always, solves that problem – sometimes a reboot is necessary).

As I said previously, rebooting the Mac temporarily clears the issue with Mail and the messages become visible again.

I am also now seeing occasional glitches and freezes with other applications I use which have never happened previously. I'm beginning to wonder if there is coincidentally a hardware problem with my new Mac. My next move will be another call to Apple.

I have also reported the problems via Apple Feedback Assistant but have not had a response.

I have still not had a chance to pursue these irritating issues with Apple vis-a-vis my new Mac mini as I am very busy but hope to do so in the next couple of days. Hopefully we will see a change with Sonoma but I'm not holding my breath.

Agree that rebuilding the index fixes the problem temporarily in Ventura but has no effect on the coincidental issue of Safari becoming unresponsive when Mail plays up.

I have also noticed that the Mac is very reluctant to re-start when these issues occur and sometimes has to be forced to re-start by holding th power button.
