Hello,
I am having this issue with two tasks in Activity Monitor draining my CPU continuously running at 100%+ both.
qemu-system-x86_64
tools-service
Haven't seen these two before, I've run malware-adware programs but my system seems clear.
Also tried to force quit but it runs again right after.
Anyone with knowledge on this issue?
Thank you all in advance.
MacBook Pro TouchBar and Touch ID, macOS Mojave (10.14), null
For what it's worth, I've finally solved the issue without having to do anything crazy. Give it a shot, it might work. Keep in mind I'm not a professional or anything, I just ran through the logical stuff.
STEPS:
1. Launch Activity Monitor and locate "qemu-system-x86_64"
2. Double click on it and on the bottom left of Activity Monitor click "Sample"
3. Once the sample has been taken, you should see lots of random digits which might intimidate you, but one of the subheadings in the sample should be called "Path:". Copy the path you see. My path was something like this: /usr/local/bin/qemu-system-x86_64
4. Launch Finder and simultaneously click "Shift" "Command" "G"
5. Paste the path that you copied from step 3 and click "Go"
6. This should locate a Qemu file, delete that immediately
7. For safe measure, we will now delete everything from your System which contains either the words "qemu" or "x86_64"
8. Press "Shift" "Command" "G" again and in the search box type "/system"
10. Where it says "search" on the top right of your finder, search for "qemu". For me this came up with nothing, but if you look closely that's because it's searching on "This Mac". Click the tab which allows you to search on the "System".
11. If this brings up a number of files, delete all of them. Make sure to empty your trash too.
12. Repeat steps 10 & 11 but instead of searching for "qemu" search for "x86_64"
13. Shut down your computer completely for a period of time. For me it was 10 hours, the time from when I slept to woke up the next day.
Hope this helps!
qemu is an open source virtual machine software to run other operating systems in your Mac. This is not surprising behaviour. I suggest you uninstall it.
Hello and thank you for your answer.
But how uninstalling something you can't see? There is no app running only this in the activity monitor!
Any luck in solving your issue? I'm having the exact same problem. The only previous things I installed were to do with music production as well!
Thanks for following up. I wasn't aware that they weren't even bothering to port code their malware to the Mac now. In addition to being malicious, that is just lazy.

You should be able to look through the report and find qemu?

Qemu is used to run a cryptocurrency miner on your computer, within an emulated OS. Chances are you picked it up downloading something from a less than reputable site.
I have the same problem. Did you just reinstall your OSX or did you reset it to factory settings? I really need some help. Thanks.
Hey, i had the same problem until i had the simpe idea to just double klick on the file and find the path and delete it :O after that i restart my mac and the problem was gone .
no
Whoever you are I love you. I've had this issue forever and I just fixed it. Thanks mate.
If qemu stops showing in activity monitor after completing these steps should you still clean install? or does that resolve the problem
some of the files that come up when i search i cant delete because they're part of the OS. Should i just accept that? is that normal? i have however deleted the original qemu file
qemu-system-x86_64 runs 100% CPU
