How to resolve Slow Email Opening on macOS Monterey 12.4

Holding down the Shift Key while launching Mail helped this time... what does that mean? This is a huge problem occurring daily. It is happening on both of my iMacs... Very frustrating.

OK, I wonder if you open Console when opening Mail if we could catch any repeating errors going by?

Well I was too quick.

Again this morning, with the boxes for privacy and hide IP un-checked

• the Mail still took 30 secs to open a new mail from a mailing list.
• most other mails do open just as fast as before
• If I say to mail Mark as Unread, and then open, it is there immediately.

Puzzled.

Today I started Mail, (Monterey build 12.4),

1. and the first mail shows its content.
2. As I move from one mail to another and back again, the content is still there.
3. and when I do that 3-4 times, then all at once the contents are not shown anymore. Then the lag starts.

So to me it seems like this too is a memory leakage problem. [One in which the Mail memory gets sort of saturated, exhausted]

Oh yes, I have changed the pointer of the mouse to being static (and unfortunately, in some programs the curser is not seen while typing.)

I have done most everything suggested even downloading a fresh OS Monterey. The only progress so far is that if I close Mail and reopen it SOMETIMES the emails will open but only sometimes. Otherwise I have to wait up to 5 minutes or more before they will start to open. This is ridiculous.

I agree with the wise Old Toad.

To help a rookie. &. To put is some experience: I also had a slow HDD drive; my first external bootdrive was a Samsung T5 (which was slow in wakeup) but I might suggest Crucial MX500.

Everything I try works for a few times then back to the same problem. The only way I can get emails to open (usually) is to close mail and reopen. Then I have access. I put my computer in "sleep mode" when not using it, maybe shutting it down would improve the email issue however it takes a while to start up. No real resolution unfortunately. Running Monterey 12.5 BTW.

I have 2 large imac's and I initially noticed the very slow opening of emails, 1-2 minutes each time on my 2017 iMac. When I called Apple they said that was normal obsolescence of software and that then only way to solve the problem was buy a new iMac , they couldn't and wouldn't do anything to solve the problem. Now I also have the problem on my other iMac a 2019 although it only happens some of the time.

Try a system update to make sure you have been keeping your I phone in top shape we have had numerous I phones and used apple for many years the system is very easy to understand and broadcast when little issues you have no clue of how or why it’s happened for.just slow down and make your way to system settings and click on general and also software update it will do the rest for you …I phone is the top of the line in leading communications and makes AnY other system seem like a slow ride or constant aggravating situation and technical difficulty try being calm and updating your software to speed up response time and you will be back in the leading companies graces before you know it .

I have the same problem using MacOS Monterey 12.6 (maybe 1 or 2 updates before that). I have reinstalled the software and rebuilt the mailboxes but that makes no difference. The email opens but it takes about 20 seconds before everything appears on the screen. I'm using an iMac 27# late 2017, I wonder if this is done intentionally by Apple. On my IOS devices everything works fine.

It would be customer friendly if Apple would confirm the problem on this forum as known and give a probable repair date.

No external monitors, just the 27 inch mac dating from 2017. So VERY OLD and obsolete, ready to be replaced. /irony

Turning off the junk mail filter seemed to work for a bit, but that loophole was quickly closed. The problem is back with mails sometimes taking several minutes to open. The only way to see the content quickly is by clicking 'reply' and reading it in the created reply mail. But then the links don't work and you need to throw away a useless draft.

This is getting to be a pain and it is slightly disheartening that Apple is staying schtumm on the matter.
