Message app slow and lags on Big Sur

The Messages app (which you send and receive iMessages with) becomes very slow and unresponsive after upgrading to Big Sur. Other apps seem to be performing fine. Do anyone else have this problem? Will it be fixed in a future release?

MacBook Pro 16″, macOS 11.0

I found this and it worked for me.

After trying all the suggested fixes, I contacted Apple. They had me do the following and it worked:

Sign out of Messages on the MacBook. We can do that by opening Messages, then going to the top left corner of the screen and click messages -> iMessages. We should be able to sign out from there .

Up next we’ll go on the iPhone to Settings -> Messages, turn off iMessage, restart the iPhone, then turn iMessage back on.

Go back on the MacBook and get signed back into the Messages app. 

Go on the iPhone to Settings -> Messages -> Text Message Forwarding. We should be able to flip a switch for the Mac to allow us to send SMS and MMS messages from the MacBook, and hopefully sort out the last of it.

Enter the code that pops up on your screen.

I agree. The fix works, but the problem comes back. It appears to be a sync problem across platforms. With a Mini, an iMac, a MacBook Air, an iPad Pro, and iPhone 11Max next to each other a message doesn’t appear on all screens for several minutes at times. Sometimes it works extremely well. I go through the suggested fix, and the results are immediately obvious, but then it comes back within a day or two.

I finally got a chance to work with Apple Support on this issue and they escalated my case up since I spoke to Support about this in September. We are trying to figure out if there is 3rd Party app that is causing this issue. If you have this issue, please reply if you have any of the following 3rd party applications to try to figure out if there is a common denominator:


Spark

Fantastical

Microsoft Office Apps (Excel, Word, Powerpoint, etc.)

WhatsApp (wish Messages worked as well)

PDF Expert

EZCCs

Ulysses

iMazing Profile Editor (or other apps by DigiDNA)

Kiwi for Gmail

Speedtest

Mactracker

OneDrive

Dropbox

There are enough people having a problem with this lag that we may be able to narrow this down by app.

I've tried everything suggested and nothing works. The safe mode solution works for maybe a couple of days and then comes back. Now it's getting worse where even opening the text on my computer gets the wheel going and deleting text is almost impossible. Is someone doing something about this?

I got the email about other app contributing to the problem. The only other app that I have from the ones listed is What'sApp.

Thanks

This gave me some relief - It's now pulling up names more quickly when I add a name to the To: field in a new message, and when I click on a particular conversation, it does load faster, but scrolling is still painfully awkward and catchy/laggy. I also tried the cursor trick (wth?!) and it didn't help at all, maybe because my cursor was already at the smallest size. Thank you for posting this! Even this partial fix will help a lot.


I hope you're on this thread, Apple folks! It took me quite a bit of time to go through this process with my home iMac, work Mac, and iPad. 😑 Please get us a bug fix! Texting is an important part of my work communication, and for many others, I'm sure.
