Is anyone using Battery 4 with macOS Sonoma and Apple Silicon Mac? I know it is not supported yet but just wondering if it works anyway. I am thinking of buying it, but I just want to make sure if it works or not with the current OS I am using.
Battery 4 is compatible with Apple Sillicon CPUS. As far as I know, people have been using it on Sonoma without issues. You can always try the demo: -instruments.com/en/products/komplete/drums/battery-4/downloads/
BATTERY 4 is the reducing-edge drum sampler designed for the 21st century. Overall this makes Battery 4's workflow faster, though one of the best development on this front comes from a brand new tagging system for individual sounds inside the plug-in's library. There's a energy and liveliness to the samples that generally makes you're feeling as if there's an actual drummer sitting next door surrounded by costly microphones! Briefly, even if this software is, no doubt, powerful, ergonomic with great sounds, it would shortly reach the above said limits which must be overcome utilizing different equivalent software packages, not necessarily in a position to do everything Native Instruments Battery 4 does.
What's additionally good to apply in battery 4 is follow making your individual default kits per style and see how many possibilities there are. Are you able to drag an audio file from wherever else, apart from Cubase, into Battery 4's pads, while it's getting used as a VSTi in C7?, then yes, you may. Battery has never been a loop participant in the way of instruments resembling Phatmatik or Intakt, and that hasn't really changed (though there's completely no purpose why you possibly can't use Battery to set off loops), but NI have added some simple looping tools.
The 143 kits in the BATTERY 4 library focus on electronic and hip hop production. 70 cutting-edge kits join all-time BATTERY favorites reprocessed for modern production. Find your drum sound with the easy-to-use, tag-based browser, drag it into a cell, and start playing.
Setting up kits is instantaneous. Factory samples and kits load with an ultra-clear color-coding system. Load your own samples and assign them colors for instant visual recognition. Innovative drag-and-drop MIDI learn lets you assign sounds to performance controllers with uninterrupted creative flow.
Working with samples has never been easier. Seven sample modes including classic sampler and groovebox emulations give you superior tonal variety. The Time Machine Pro algorithm delivers unparalleled time stretching. A gorgeous waveform display lets you adjust start and end points, volume curves, and more. And instant cell rendering allows for easy kit building and creative sound design.
State A a USB-C hub (a mouse and keyboard, plus power) and a USB-C HDMI 2.0 adapter, both on the left side. You can see the Thunderbolt Left Proximity temperature sensor rise quickly. About 3-4 minutes later the dreaded kernel_task high CPU usage starts.
This is causal. Moving power back to the left side, restoring State A, quickly restores the temperatures and kernel_task again comes back after 3-4 minutes. Again moving power back to the right side, restoring State B, resolves the problem immediately.
State C shows that simply having stuff plugged in to TB ports raises their temperature significantly. Both the hub (mouse and keyboard ONLY) and HDMI adapter individually raise the temperature about 10 degrees, and 15 degrees together.
Note that high temperature on the right side appears to be ignored by the OS. Plugging everything into the two right ports instead of the left raised the Right temperatures to over 100 degrees, without the fans coming on. No kernel_task either, but the machine becomes unusable from something throttling.
The only way to actually ask the kernel what it's doing is to attach a kernel debugger. That means getting a debug kernel from Apple, rebooting, then using a second Mac to attach to the debugged machine. You can then examine stack traces and guess what they mean.
If you're encountering this on Macbook Pro 16" (2019), this seems to be a well-known problem regarding the laptop body not being able to handle the heat from both the CPU and GPU when external monitors are connected. The ultimate solution seems to be to use an eGPU... which would probably not be practical for most people.
Update 2: I finally had my eGPU set up and as expected, the MBP 16" hasn't suffered from throttling yet since then. I guess you could still consider this as an option if all other alternatives fail. You don't need a fancy/expensive graphics card. I am driving one 4K display and 2 additional displays with an RX 580 without any issue.
Update 3: Now I see some folks recommending limiting the CPU frequency with Turbo Boost Switcher. I didn't try it while I was using my MBP 16" since I already had the eGPU (BTW I'm now using ARM Macs where this problem is completely gone), but it might be worth checking out.
As it persists for a very long time, and it persists across restarts, it seems likely that your problem is caused by a hardware problem - namely lack of cooling. You do not describe which type of computer you have, but try looking at its cooling to see if it's working as intended. You might have a broken fan, lots of dust or similar.
The kernel_task virtual process does, amongst other things, throttle CPU usage in order to keep the CPU below its maximum operating temperature. The purpose is to keep the CPU from shutting down unexpectedly. kernel_task does this by ensuring that the CPU is doing nothing for long periods of time - essentially making sure the CPU uses as little power as possible, which means that it gives off less heat. This makes it seem like kernel_task is using a lot of CPU, but in reality it is not.
For me this happens almost everytime I connect to an external monitor. The graphics switches to dedicated ones and the system starts to overheat in just under 5 min. Took me quite a while to figure this out. Room temperature is 27C so I don't think it's related to hot weather as well.
For me, the issue went away when I switched to a charger with higher watt capacity. I accidentally had been running with a 15W charger instead of 87W. This caused the charging to be prolonged, heating up the whole computer.
In your case, Skype and Firefox are getting all the cycles left over due to running hot. Windowserver and kernel just do the bidding of the other programs. Also, for a longer term view of what the CPU is doing, watch the energy tab in activity monitor.
Macbook pro 15" 2018, I have a usb c adapter (7 in 1) 2 monitors, and 2 external usb hdd, the adapter on right side and on the left only charging, I have a few months that I can't work in multitask only a few apps and the macbook just starts burning out extremely, I discover this kernel_task service going to thousands!! on percent column on the activity monitor, after play around connecting on different ports (hdmi, usbc and the dock) the kernel_task just go back to normally!!! my working configuration was move the charger to the right side and one of the monitor cables to the left, so on the left I just have a usbc-hdmi cable and on the right side I have the dock with 2 usb ports used along with the hdmi for the second monitor and the charger, great testing Adam!!
Look at you kernel panics and logs to see if there any reoccurring issues.
Make sure your fan starts spinning up when the computer gets warm. If not it could be a SMC issue. You can download software to control the speed of the fans to see if it reduces the CPU %.
I own a MacBook Pro (15-inch, 2016). The theory given in accepted answer is correct that the cause of high cpu usage by kernel_task is due to the fact that you are plugging the charger in sockets at left. Using sockets at right immediately fixes the problem and the cpu usage for kernel_task dropped as well. However following are my findings,
The problem did not occur till the MacOS Catalina update. The charging from left as well as right was fine on High Sierra and Catalina in my experience. I hope that Big Sur will acknowledge the problem and possibly fix it. You can try downgrading the OS and see if it fixes the problem.
I recently replaced 3 year old stock thermal paste with Thermal Grizzly's Kyronaut and cleaned the dust accumulated over years with an anti-static brush. The results are amazing. I am no longer facing the over cpu utilisation by kernel_task while charging from either side. The fans are at 2000(ish)RPM on idle whereas it was 2600(ish)RPM.
Edit: Please read through the post as to how I came to the solution, since the underlying factors of how I experienced the slowdown and found the solution are also important, especially to those with similar setups. This is not a lengthy "I have this problem too" comment, since though I do have the same kernel_task issue, the conditions of how I was having it as well as my setup are NOT the same as most here.
I've been having this problem on occasion back then with my previous MBP152011 (yes, the one with the nasty GPU issue) which slowed down while charging. A battery replacement kind of fixed the problem, but, with the GPU issue, it wasn't really long after that I had to replace it. It did serve me well for more than seven years (5 years original Motherboard GPU + 2 year replaced motherboard).
Now, after two years of using it, it was scheduled for a battery replacement since the battery started to bloat. I was able to use the Thunderbolt ports with no issue, but I was using the one farther from the charging port ever since I got second external monitor. The first external monitor has always been connected to the HDMI port, which was on the right side.
It didn't. I get a massive CPU slowdown while the MBP was charging, often between 40-80% charge, but sometimes, even beyond that. I don't have any other third party apps installed that shows in Activity Monitor or Stats, so I was already down to the last resort: Backup, reformat, reinstall.
