Typing in Messages is 'laggy' since installing Mac OS Sequoia 15.1 update

Yep, me too. Been happening for months (I'm not sure of the timing coinciding with a software update). 2018 15" pro. Hasn't happened with any other apps for me, just iMessage.

It's to the point of being unusable for anything longer than a couple of lines, and sometimes the lag starts on the first line or two. Really frustrating and annoying.

Since installing the macOS 15.1 update (16" M1PRO), I've also been experiencing significant keyboard lag in the iMessage app only.

Moments after a reboot, everything works ok, only a minute after loading the system the problem returned.

The temporary solution to the problem was to disable real-time file system protection in Eset Cyber Security.

Does anyone know a permanent solution to the problem of significant typing lag in the iMessage app (ms teams work without problems)?

I don't want to give up ESET protection at the expense of writing in iMessage.

What is malware? - Apple Community

is it related to Apple inteligence activation?

I had this exact same issue and strangely the way I solved this was by... enabling Apple Intelligence. Up until that point, Messages was incredibly laggy while typing.

Agreed. Slow Keys is off and my key repeat and delay sliders are all the way up. The speed is as expected everywhere else but messages.

Wish it was available on 2019 Macbook Pros then :D - we don't even have the option to enable it.

I suspected that and disabled both Apple Intelligence and Siri, but to no avail. However, I briefly had Apple Intelligence enabled, and it's possible that it actually is not fully disabled now and messing with the Messages app.

I had this issue too for both iMessage and WhatsApp running on Sequoia 15.1 and ESET. Here is what fixed it for me if you are ok with disabling this setting with ESET while they solve the issue in presumably 15.2 release:

Turning "off" in ESET Settings > File-system Protection > Scan on \ File open (Disabled)

I also am running the same OS version but am on a 2021 M1 Pro. However, I can't find this setting. Searching for the words ESET, file, scan etc. shows nothing in System Settings. Can you please help with a bit more details?

Can confirm that turning on Apple Intelligence solved the problem for me. Apple must be using Apple Intelligence for something when you're typing a message in Messages and it craps the bed if it's not there. Hopefully they will fix this soon.

same here, Sophos premium but if you disable protection, it works fine for a few minutes and back to lagging, so its an issue with both Anti-Virus and also those without any software protection, so there is something going on with apple regardless.

This issue has existed for me since well before Sequoia, and in fact started about the same time that Apple first released Apple Silicon devices.

I run into this issue on a 2018 Mac mini (3.2 GHz 6-core i7, 64 GB RAM) running 15.1, but have noticed it since at least Big Sur came out, and it may have started with Catalina.

Having the same exact issue. Sequoia 15.1 running on a fully loaded Mac Studio. Apple Intelligence is on, and I don't have anything like ESET Cyber Security installed. Only "solution" I have right now is to enter my Messages text in a separate text editor such as BBEdit, then paste it into the Messages window. Otherwise it's just too unbearable to type directly in Messages once the message reaches a certain length. I've only noticed this occurring in Apple Messages on the Mac. Sure hope Apple fixes this bug soon.

I've been having the exact same issue, both in iMessage and WhatsApp.

This, on an MacBook Pro running a M3 Pro. Even the latest update to MacOS did not fix the issue for me.

Hoping for a workaround in the short-term until it gets completely fixed.

I’m on a Macbook Air 2020 M1, after updating to 15.1.1 typing Whatsapp chat messages is ‘laggy’ (dont have this prob on my iphone though). I’ve tried deleting and restoring whatsapp on my mac but the problem remains.
