Apps freezes when paste images on Apple M1.

I met this problem almost on the first day I got this m1 mac. I think this is related to chromium because all these apps are using electron or sth similar. Also, small pictures are OK. Pasting to WeChat is very fluent on the other hand. So I guess the issue happens when:

1. Using Apple M1 chip
2. Using chromium to paste a picture from the clipboard
3. The picture is larger than a certain size(like a full-screen snapshot will reproduce it)

Here is my version info for mac and chromium.

I also thought maybe WeChat screenshot has some special format that other apps can't understand. However, I ruled out this possibility after using the native screenshot tool for a while.

Now my workaround is

1. Paste that image into WeChat and re-snapshot it with a lower resolution(if the resolution is not important to this snapshot which is the most commons case)
2. Paste that image into wechat and save in the File System and upload through file(if the resolution matters)

Hello OscarDykeman.

Welcome to Apple Support Communities. We understand that when you attempt to paste content in some apps the apps become unresponsive. We’re happy to help.

Let’s try the steps here: If an app freezes or quits unexpectedly on Mac

We also recommend updating your apps using the steps here: How to manually update apps on your Apple device

Take care.

I have same issue too. Pasting image from clipboard to Chrome or Slack sometimes crashes the app. It's not 100% it's sometimes. Sometimes it works fine, sometimes it freezes the app and i use force quit the app and then restart and try again. It have never ever happen on any mac for me be but this new-ish M1.

I'm not sure about this, but maybe it's related to Chrome, while Slack is built on top of same tech. Slack built on Electron, Electron uses same underlying engine software as chrome, could it be the reason? I don't really use any other apps to paste images, so can't tell if it has any relation to issue.

I have node apps crashes in report, don't worry about those. i do some development with node.

I don't see anything obviously wrong with that report.

However, there are several kernel extensions, which are almost certainly built for intel macs, and there is a chance that one or more may not be handled successfully under Rosetta on the M1 mac.

I would not say "risky". And I agree (from my somewhat limit and indirect, experience) that the benefits of this machine are awesome.

Do you require these, perhaps to control your pointing device? If not, then I'd try deleting them:

/Library/Extensions

Wireless360Controller.kext - com.mice.driver.Wireless360Controller (1.0 - SDK 10.11)

WirelessGamingReceiver.kext - com.mice.driver.WirelessGamingReceiver (1.0 - SDK 10.11)

WirelessOneController.kext - com.mice.driver.WirelessOneController (1.0 - SDK 10.11)

360Controller.kext - com.mice.driver.Xbox360Controller (1.0 - SDK 10.11)

Exactly the same as what?

Without any information, it is impossible to tell if your problem is the same or completely different.

No two macs are the same, because they don't have the same software installed.

The OP had problems with many applications. Do you see it just in Slack?

If it wasn't too obvious already, I meant that Slack often crashes when you paste an image from the clipboard.

Not sure if this is a M1arch specific issue or simply a Big Sur one.

Keeps happening even with the latest updates on both OS and Slack app.

Please run Etrecheck and post its full report here.

Exactly the same is happening to me on Slack - super frustrating!

same here with various apps from pages over photoshop to whatever. copy something, paste, and the app freezes.
