I've had my macbook pro repaired a few weeks ago (new battery and keyboard).. Ever since then every time I boot it its superslow ... + with high activity on kernel_task.. When I close the lid and open it after 5 seconds again the problem is gone.
View 7 RepliesNoticed i was uploading at high speed (8MB/s) constantly. So i check activity monitor, and kernel_task is uploading huge amount of data, so far 20+gb this morning...
I'm not getting a massive CPU usage (10-15%).Â
Tried restarting, just starts up again after a couple of minutes.

My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?

I have been experiencing the fan running at high rpm and the computer completely slowing down when there is slight pressure applied to the bottom of my macbook pro. I went on Activity Monitor and it shows kernel_task running at over 100% cpu usage. I have already tried resetting PRAM and SMC but those did not work.

I had my first leopard problem on my 1.67 15" powerbook last night. I lost bluetooth so I restarted, I went to the activity monitor and there was a kernel task eating up 152 mb of my ram. All updates are current and I have 2gb of ram. Any ideas as to what this action is doing. I also have a dual 2.4 g5 with 3.5 gb of ram(but no kernel task issues).

In the memory tab in activity monitor, it shows kernel_task which takes up 440 MB. It takes a huge amount of my memory. Also, my macbook pro is running down. I believe that one of the reason for this is kernel task. How do I fix this?Â
Is there any specific reason Kernel_Task seems to think he owns the place? What gives? It's like I turn my MacBook on and he's all like "oh hai! Ize just a system task! 50mb of memory? That's cool that's cool" Then only 2 hours later he's all like "Nah man, I just needed some more room see, it's like 120mb ain't dat much, k?"
I know that OS X handles ram real good and all, by freeing memory when it's required for higher-priority tasks, but I also know that it takes a bit more time to clear that memory AND re-allocate it...
So, is this a memory leak? And while I'm at it what about iChat Agent and Colloquy that are battling out to be RAM champ?
OH, and I haz 2gb installed at the moment.
I've been recently realizing that every time i use safari or socialite for a few mins I get a lot of 'beach ball' time. The application would show in red (not responding) in activity monitor and kernel_task would have over 1,900 threads, that will decrease slowly after I force quit the applications.

Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?Â
About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?Â

I have a 13inch MBP running Mavericks 10.9.4 with a 2.7 GHz i7, 16GB RAM, 500GB HD. I just recently had the machine Factory Reset. The only APP's I've added are PAGES, NUMBERS and KEYNOTE. When I check the ACTIVITY MONITOR it indicates that out of 16GB of RAM MEMORY, 5.51GB is being used. Usually ACTIVITY MONITOR indicates that as much as 9GB RAM is being used. This MBP is 3 years old and I clearly upgraded the RAM from 4GB (I think) to 16GB. Since this MBP used to run with only 4GB of RAM total; it seems to me that the current amount of memory being used, from 5.51GB up to 9GB out of 16GB total RAM is unusually high. In addition, the above numbers were displayed when only Safari and Activity Monitor are running. Is this normal for Mavericks OSX?

When I open Activity Monitor, kernel_task is using approx 240 MB of real memory, and 67 of virtual. All I have open is Safari (and Activity Monitor)Seems like alot of real memory for one process.
View 6 Replies View RelatedA few hours ago, I noticed my MBP start hanging and generally processing very slow. Apps would freeze at random times, and generally a lot of odd behavior.
I checked the activity monitor to see what might be causing this. It turns out, the process "kernel_task" is using almost 100% of my CPU. It has stayed within the 70-100% range, and has yet to go down. I tried many things, including restarting my Mac many times, but it remains the same.
Does anyone know why "kernel_task" is taking up so much of my CPU? Is there a way to somehow "reset" the process to get it back to normal?
P.S. I attached a screenshot of the process in the Activity Monitor. You can view it here:
EDIT: I just want to add that I think the "kernel_task" might have started eating CPU when I stopped a RAR program in the middle of extracting an archive. I'm not 100% sure though that this is when the problem started.
Recently I've seen my Mac Pro 8-core CPU temps rise pretty considerably, between 10-15C after a bone head move on my part. After setting up a new Vista x64 virtual machine in VMWare Fusion 2, I was trying to get a Linksys USB to Ethernet adapter (USB200M) to work inside this virtual machine, but with little success. After tracking down a driver online which I thought at the time was a match for the chip on the adapter, I tried to load the driver manually in the virtual machine. This unfortunately resulted in an immediate OS X kernel panic; my first and only on this machine. Since then, my CPU temps have been on the rise. Not sure if its even possible for a kernel panic to damage hardware, but I'm wondering if any low-level software damage resulting from the kernel panic could be causing the higher temps?
I tried a simple restart which did nothing. I have since run the extended Apple Diagnostics and everything appeared OK. Also, ran a "fsck" check and everything appeared OK there as well. Is it even possible to damage hardware from a kernel panic? Finally, my kernel_task process seems a bit on the high side 83 threads, 350MB Real Memory and almost 2.5GB Virtual Memory. Could this be related to the kernel panic and indicate that I probably need a clean install of Leopard at this point? This is an Early 08 2.8GHz 8-core Mac Pro with 10GB third-party RAM. RAM has been thoroughly tested and running in the machine for over a year now without incident.

I have a March 2011 13" MacBook Pro. Up until now I have had no problems with the laptop. At the start of this week the charger started to stop working once the battery reached 100%. Up to 99% it charges and the amber light on the charger is illuminated, at 100% the light goes off and the 'more info' screen shows now current flowing through. I then have to wait until the battery dies until it can be recharged. Battery has done 218 cycles.
View 3 Replies View RelatedI currently have external storage devices by DataRobotics - 2 DroboPro and 1 DroboElite. I bought the new MacPro 2 months ago and have been having problems with the Drobo devices disconnecting constantly. After a lot of diagnostics including Apple replacing the logic board in my MacPro, it was identified that the issue was with the iSCSI initiator that DataRobotics uses. It is not 64bit kernal compatible and as a result, the drives disconnect randomly especially when moving data from one external drive to the other. I am forced to boot the MacPro in 32bit kernel mode for the drives to work properly. DataRobotics is not committing to fixing the 64bit kernel issue so I'm now looking to replace this technology.
I found some interesting technology by Netgear and was considering buying their product, however, I had the worst experience ever with dealing with pre-sales & technical support department, after dealing with 4 different individuals, I concluded that they have no clue about their own products, the staff is so junior, it's as if I called a completely different company when talking about their own product. I am therefore going to stay away from that company.
My imac became very slow all of a sudden (stalls when clicking and typing), 2-3 mths after Lion (not sure it's related), mount_hfs and syslogd taking up 80-99% of CPU in Activity Monitor.After digging online, checked my Console and found repeating messages exceeding 20,000+++. But I'm not sure what is being repeated (sample below).I've already turned off Time Machine.I was able to delete the syslogd activity, but still left with 99% mount_hfs, which 'maybe' related to the 20,000+++ repeated messages.Not sure if it's relevant...but I was digging through my asl folder, and it is up to 10g for a single date for some reason!

Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.

I have been trying to boot into 64-bit kernel in Snow Leopard on my Late 2008 Aluminum MacBook (2.4 GHz), but it is not working. It is running the 64-bit EFI firmware and is updated to 10.6.1.

I've been testing this method for awhile to determine if it was possible to boot the x86_64 kernel on the Macbook Air via any process. It looks like it is. References here and here show it is possible to force boot the x86_64 kernel if you have a 64bit EFI firmware. To test your EFI firmware you can use the following: (Source).
Type the following into Terminal:
ioreg -l -p IODeviceTree | grep firmware-abi
If your Mac shows "firmware-abi" = EFI64 then you can proceed. If you see EFI32 then you're out of luck for this particular method.
The rest of the process is detailed at the links included above. I will rewrite this part when I have the method fully working, but for now I haven't been successful.
There are several relevant parts such as:
Quote:
Model (with 64-bit EFI) Byte Position in boot64.efi Old Value New Value
Mac mini(Eary 2009)　0�266DB 0�00 0�80
MacBook Air(Late 2008)　0�266FB 0�00 0�80
iMac(early 2008) 0�2671B 0�08 0�80
included in the comments at this page, but so far I'm stuck.
Update 1:
As an alternate method I attempted to use lipo to modify the mach_kernel to only contain the x86_64 kernel information. A reboot confirms this didn't work so well.
Interesting notes so far from the EFI modification tests:
1) bless --info works fine on 10.6.0, but gives a Can't access "efi-boot-device" NVRAM variable on 10.6.2.
2) You can still modify which efi file is used for boot in 10.6.2 (I fouled one up in a hex editor and rebooted to see if it would fail just to test it), but the bless binary will not show the information the system is configured with.
3) The information at both links above for modifying the boot.efi doesn't seem to work in 10.6.0. It already wasn't working in 10.6.2, but there were some comments about it working in previous versions of Snow Leopard so I went back to an unpatched vanilla install from my install media (used Disk Utility to format the drive before installation) to test it.
Thread Notes:
1) Yes, I am aware that Leopard and Snow Leopard are fully capable of running 64bit programs using the i386 kernel. This is just an experiment for fun.
2) No, I do not have any reason to do this and I know the Macbook Air runs fine with the i386 kernel including every feature of the x86_64 kernel.
3) Yes, I know the Macbook Air only contains 2GB of ram so there is no reason to run the x86_64 kernel.
I have a 2-yr old MBP 3,1 (the first Santa Rosa line) which has recently hit a slew of problems (bad fan, new display, new hdd, new logic board) over the last 3 months. I thought all was fixed then yesterday it suddenly dies, starts kernel panicking on boot, and I can't even boot from an installer disk. I took it in to the Genius Bar today and the guy puts a stick of their RAM in and it seems to work +/- ok. He won't do any more until I put the original RAM back in (upgraded to 4 gigs a year ago). I take the laptop home, and it magically starts working. I grab a couple backups and it starts kernel panicking again so I grab my original RAM and put it in. Now it's still kernel panicking and I'm effectively completely locked out of my MacBook Pro (the RAM worked fine in my wife's 3-year-old MacBook which takes memory of the same specs).

About three weeks ago, I made the stupid mistake of attempting to run iOSX so I could dual boot with Windows 7 (all stuff I acquired while I was home on midtour leave.) The install seemed to be ok, however, I noticed immediately I could not make any changes to settings as my administrator password was no longer working. (Administrator is my only account on this laptop.)
At fear of losing my operability, I simply did not power down for that whole time. However, I recently moved bases, and alas, the time came to power down.
Upon bootup, I get a constant spinning wheel. I left this on for a couple of hours just to be sure, then realized it was a lost cause. I tried booting in safe mode, and I got some kernel panic. It says a bunch of stuff about debugger calling the panic, bla bla bla, but the thing that caught my eze was Mac OS version not set yet.
After booting in safe mode, getting that error, and powering off, my laptop will boot into a grezish blueish lightblueish (alternating) type of screen, which sometimes has the spinning wheel, sometimes not. Again, nothing.
I understand I will probably need my OS disc to fix this, but I didn't bring it with me. Am I SOL?
My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed.
