Sequoia 15.1 is slows iMessage & WhatsApp keyboard input

Same problem here. Typing lags in Messages (I don't use WA). The issue started immediately after installing macOS 15.1 and continues regardless of multiple restarts and whether other apps are running or now.

System: MBA M2.

I have these issues across all messaging apps including iMessage, ConnectTeam and Whatsapp. The lag makes text entry almost unbearable. I often have to write a message in an email draft and paste it in to the messaging app. 2020 M1 MBP with 16GB RAM. It started with Sequoia .0 and stayed the same with .1

Stopping real time protraction with Sophos improved (not completely) Whatsapp and iMessage but not ConnectTeam

This is interesting because it's now three messaging platforms (Messages, Whatsapp, ConnectTeam) that have lag due to real-time file scanning. Signal is not affected by the issue. It begs the question of the difference in writing to local files between the apps.

I can confirm this is happening to me as well. MacOS Sequoia 15.1.1 causes an extremely laggy typing experience in messaging apps such as WhatsApp.

It is discouraging that this was reported almost a month ago and still has not been fixed.

Hello!

I'm having the same issue, I'm using a workaround that might work for you:

On Safari, open web.whatsapp.com and link your WhatsApp there.

Then, on the "share" button on Safari's bar select: "Add to dock"

Then you have a Whatsapp white and green icon that opens Whatsapp web but pretty much looks like the app and it's not laggy :)

Hope it helps!

I have Sophos but disabled realtime scanning did not help. From the other reports this is an OS, not a third party app issue.

It's quicker to open iPhone mirroring on the desktop and type messages into the app...

Anyone solved this yet?

Accidentally found out the main reason for the laggy keyboard input is ESET.

When I had to re-install Mac OS and during a course of installation, ESET was deactivated. I had no issues on keyboard input on both WhatsApp and iMessage.

I am trying to performance exclusion on WhatsApp and iMessage, but I'm not sure which directory I should exclude.

Any idea on this?

Hi Carsten,

I also have the same problem as you (MB-pro M1-pro). I restarted the Mac and it seems to improve the situation. I hope I can help you

I've 2 Mac, one face this issue but not the other.

the one with this issue is M1 MBA with 16GB RAM,

The one that has no issue is M1 Max MBP with 64GB RAM

I have got the same problem! Waiting next update to fix it.

In my case I could fix it! The problem was Sophos endpoint, I uninstalled and the problem vanished.

any luck? I have MS Defender too

I am facing the same porblem on both of my Macbook Pro (M1 and M3)

Same here - I have the lagging issue with WhatsApp.

M2 Air - 16GB Ram - 15.1

Same here, M1 Max, 32Gb, 2To, Sequoia 15.1 (24B83), the inputs on iMessage & WhatsApp are super laggy, almost impossible to use. A shame :(.
