I would be interested to know if the current version (4.6.11) is already compatible not only with Big Sur, but also with Apple M1 or if a new version will be released (first obviously in beta).

Before any future purchase, I would like to be sure that Malwarebytes can protect me.

Thanks

Have a good day

Massimiliano

The 4.8.10 beta appears to have fixed the time machine app launching issue.

The current 4.6 version was built using SDK 10.15, which should mean it is Intel only code. It should still run on an Apple Silicon Mac using Rosetta 2, but until someone takes delivery of such a Mac, we can't know for certain.

I hope, as soon as possible, in a M1 Compatible version because running an anti-malware with an emulator (however good) I don't think it's the best

I'm sorry, but I'm not sure I understood correctly:

Would you say that Malwarebytes is able to protect the Mac even if run emulated with Rosetta2? 
I think a confirmation is important (preferably with a pinned post at the top of the forum with a more detailed explanation)

I ask because I was convinced that an anti-malware needed to access operating system resources only by having native code for the CPU than any other application (e.g. Office, Photo, Mail).

Thanks

Perhaps you haven't read up on Rosetta 2. Unlike the original Rosetta, the new version is not an emulator, rather when you launch an Intel only app, Rosetta will translate the Intel code into Apple Silicon and embed that code within the app itself, effectively converting it to a Universal app from then on. So running the current Malwarebytes on an M1 Mac will be running native code immediately after first launch.

Thank you for your answer.

Could you please provide me the link, which you read, in which this feature of Rosetta 2 is explained.

I would like to understand more about it (especially about software that works at low level as I think - maybe I'm wrong - an anti-malware or similar)

You can find more information here:

https://developer.apple.com/documentation/apple_silicon/about_the_rosetta_translation_environment

And yes, Malwarebytes for Mac will still protect your Mac on Apple Silicon, even though it's currently Intel code. Keep in mind that Malwarebytes for Mac no longer has a kernel extension on Catalina and up, so there is no low-level code to worry about.

Greetings! 

I've confirmed that the latest Malwarebytes will not work with Rosetta 2 on a MacBook with an AI chip and BigSur 11.0 or 11.0.1. 

If an application is coded as such, you should be apple to open the properties for the application and set it to run with Rosetta 2; however, that option is not present with the latest version of Malwarebytes and as such, it will attempt to run in native Intel code. 

Because of this, its causing a new MacBook Pro MYD92LL/A M1 Late 2020 13.3" initially on BigSur 11.0 and then upgraded to 11.0.1 to crash with the attached error, regardless of the BigSur build. 

The console log at the time of one of the many crashes, showed the following below.

I will have to get back with the individual that we were testing Malwarebytes on to fully confirm; however, it was the only available version on your website for Mac, downloaded back on 12-08-20 w/a premium key, version 4.6.12.3825 last I checked.

Hi. I have the new Mac Mini with the M1. Running MB Premium 4.6.12 via Rosetta 2. MB was one of the first things I put on the machine when I got it. I noticed that when doing large network transfers, Chrome and other internet using apps would slow to a crawl. Become unresponsive. It was very odd. Spoke to Apple about it and did a reformat of the whole system. Didn't install MB this time and ran perfectly for a week till today when I installed 4.6.12 and right away Chrome started to do the same thing anytime I have a network drive mounted with data being copied OR Time Machine starts up in the background. I turned on BETA updates in hope that there was something newer being tested but sadly no. Anyways, just wanted to inform you and I hope there is a native M1 version BETA soon. Thanks.

I do. That is why I was saying that anytime there was network traffic the performance went down significantly. 

I happen to have the exact issue only during network time machine backups; performance was unaffected during large downloads and even iperf. From my testing, the issue persists after a clean install and doesn't seem to be related to malwarebytes at all. However, since the only other user that I know of with the same issue (you) found a relation to malwarebytes, I'll uninstall and test again to make sure.

Also Malwarebytes had to be removed, due to it causing the Mac with an A1 chip to crash, so no its not currently installed anymore. 

I have not been able to reproduce this issue with the M1 chip. It's been working just fine so far, though more testing is still needed.

Big Sur and Rosetta 2 are still new, and there have definitely been some bugs - some that we've reported to Apple, and some that others have reported. Once Big Sur 11.2 is out of beta, if you're willing, I'd be interested to hear if the problem persists with 11.2 and our Malwarebytes for Mac 4.7.9 release that's coming out later today.

I am running 4.7.8 since I checked off beta releases till the native M1 version is official.  Happy to use it with 11.2 when that is out.  I do have one bit of info to add. So I had to swap my Mac mini with apple due to screen glitching issues.  I started to get purple boxes on the screen on the login page and when changing full screen apps.  I got that swap done yesterday and so far on my first day of testing it I haven’t seen the same performance issue.  I’m wondering if apple had issues with early production models. All guesses on my part of course.  But the new one I just got doesn’t have any network traffic issues so far.

On the Time Machine issue, are you guys both seeing this only 1) with network backups, and 2) with M1 Macs? @insaniac80@Omoeba

I can't say what might be going on here, considering that we don't scan external or network volumes and we don't filter network traffic on macOS, so I'd like to hear more.

Ahh, that's good to hear! Hopefully that will solve the problem, but please keep us posted if there are any changes.

For me, the issue only occurred during network time machine backups with the M1 MacBook Pro. I can send you a spindump taken when the issue was occurring if you want.
