14.3 Mail.app - Corrupted/Garbled Text When Composing Messages

Same here. MacBook Air M1 2020. Upon updating to Sonoma 14.3 (which I had to do because suddenly Netflix wouldn't work unless I did), Mail and Safari both keep "flashing" several lines of text that are what I typed already. It will display the "wrong" text on both sides of the cursor, but it hasn't *really* replaced the text. If I get the screen to resize or otherwise "disrupt" the display it will improve. It's even happening right now in a chatsupport.apple.com window.

At the same time, about 50% of the time I'm trying to visit websites, Safari says "can't display page because you aren't connected to the internet" even though I am connected to the internet. Another person right next to me on a different brand of computer is having no issues.

I hope someone also looks into what's going on between Apple and Netflix that FORCES people to update their OS to the latest version when they aren't even very far behind. Users should have the option of waiting until an OS update has been out for awhile before updating their OS.

Adding my name to the list. Running 14.3 on an M@ MacAir.

A temporary fix (so I can finish an email) has been to resize the Mail.app composing window. I will record and take screen shots so I can call tech support and get it escalated (like others have suggested) to make sure enough higher-ups are aware.

I didn't install the safari beta but I did turn on lockdown mode on my Mac and restarted. Then I tried to see if it would happen in mail typing many paragraphs but it didn't happen. Not sure if this helps or if you were using lockdown mode. I only tried one email though so will have to see if this makes any difference. I wasn't using lockdown mode when this text issue kept happening. I am using a 2018 Mac mini Intel model.

The workaround I've been using in Mail: Once the bug rears its ugly head I save the message as a draft and close it. Then I open the draft back up and continue working on the message. That fixes it... at least until it starts happening again. Rinse and repeat.

Mac Studio, M1 Max

Guys, for what's it worth spent a week with Apple on this and the community figured it out before them (lost a week of my time). Two thoughts, I did turn off the Auto suggest in Keyboard (and does help a bit, does it get rid of it, it does not, but it kicks in a bit later in the text.

Next Hack, I compose my emails in Text Edit and then copy and paste since as you guys know once it gets garbled you are clicking in and out of the mail app to get it to correct and that is both annoying and time consuming, so writing in text edit does at least solve that. Don't waste your time on new user, plist any of that stuff, nothing helped. I am sure they will have a fix at some point. I have two other Mac minis with 14.2 as well so that does save me a bit. At least we know we are all not crazy :)

I am having the same problem with garbled text in Mail since switching to OS 14.3. I think my temporary solution will be to write long text messages in MS Word and then copy them into Mail until Apple corrects this problem, which I hope is soon.

Just had this issue also occur with a long text I was writing in iMessage on Mac where all of a sudden the beginning parts became garbled and wrote over the original text. Except unlike the email, when I tried to revive the original message it instead replaced with the garbled text, and now I can't see the full original message I was composing. Can't even Cmd Z either. Not good.

Thanks for the reply. For some reason, my message has been moved to earlier in the thread, at least in my browser (in fact, I posted again because I thought it had been lost). I don't know why the forum mangles threads in this way, because it makes it almost impossible to keep a coherent conversation going.

Yeah, this issue is happening to me as well; 14" M1 Macbook Pro. ANOTHER issue I just found is when I went to top menu and dropped down to 'Save', my message was SENT (and not saved) ! ! ! And of course the message wasn't finished and ready to send. Had to send a quick message to recipient apologizing for this. This issue, like the garbled / large gaps appearing randomly, should NOT be happening at this stage of 'the game'.

Happens both on MacBook Air M1 and also on IPhone 13. So far only in the mail app.

I’ve seen the workarounds for MacBook, but are there any work around for iPhone?

Does typing the message in notes and then cut and paste into the email work for either iPhone or MacBook?

Identical garbled Apple Mail problem in 14.3, using a late 2021 M1 MacBook Pro. Note that I'm writing this more than 2 weeks after this issue was first reported, and still NO response from Apple. (Don't they monitor these community forums anymore?) I'm one of hundreds reporting this snafu, which has made one of the most fundamental reasons we have computers -- communicating by email -- a daily battle. Apple, if you're actually reading this, please remember that email is an essential way your customers do business. If you don't want us to take our business elsewhere, fix this already.

I first saw this happen some time ago when I used speech recognition to dictate emails and thought it was associated with that technology. Now, it still happens when using speech recognition, but it is also happening with keyboard input.

Does the 14.3.1 update fix it? I sent in feedback with a link to this thread the day before it came out so maybe that helped?
