OS X V10.7 Lion :: Mtmd And Mds Doing Huge CPU Load
Apr 27, 2012
I never had the problem before, but now all of a sudden mtmd and mds processes consume huge amounts of CPU (+250% together) and I cannot really work on the laptop. It pretty much started after my external Apple 24" monitor froze and I had to hard boot.I am running Parallels and made Bootcamp "private" because of other performance problems with mds.I am also running backups to Time Machine, but have now been forced to turn this off.
When running Kaspersky AND Time Machine turned on - I cannot work at all.So, was there ever found any solution to this (other than turning off Time Machine, which is probably not the intension from Apple).I am running X Lion on a 15" Mac Book Pro from June 2010, 2,66GHz, Intel Core i7, 4 Gb DDR3. All software updated as far as I know. Also, just updated the firmware on the Time Capsule.

Why are alias files so big now? Before (OSX 10.3), they were rarely bigger than 1 KB, but now (OSX 10.7), they're often up to 1.6 MB! Can we do something to keep them small? As I understand it, an alias is just a pointer or reference to another file. When you open or print it, the operating system actually opens or prints the original file referenced. All that needs to be stored is the directory path to the original file, either (or both) as a full reference or a relative reference, plus its file system ID and perhaps a drive ID (in case it's moved). This should take only a few bytes. On prior Mac operating system versions (e.g., 10.3.9), these alias files were just a few hundred bytes in size, rarely over 1,400 bytes total. But now I notice that, under Mac OS 10.7, newly created alias files are always hundreds of KB large, and can typically be as huge as 1.6 MB! The custom icon only accounts for a fraction of this size. However, sometimes they can still be as small as before (only a few hundred bytes). Old aliases from a prior OS version (usually but not always) still work in opening their original file, so apparently we don't need the extra size. So, what is in these files?! I know these are analogous to "shortcut" files under MS Windows, which are not that large. Having aliases be so huge defeats the purpose of a small file reference that can be used in multiple other places. One would like to use an alias so as to not have to keep a copy of a large file. But I notice that MB-sized aliases are often created even when the original file is a tiny 1 KB file. Moreover, a larger original file might create a smaller alias than that for a smaller original file, even when both original files are in the same folder. What gives? I use aliases extensively, so as to keep references to the same original file in multiple folders, since these files fall into the multiple categories that each folder contains. By using aliases, I ensure that there is only a single "master" version that is edited when a file is opened from any of those folders. Many of the original files are pretty small, yet their aliases are many orders of magnitude bigger. This is very discouraging towards using this handy feature. Is there something I am doing wrong to end up making them so big – perhaps a system setting? What is in these files that they need to be so huge? I suppose I can use Unix symbolic link files by using a command line in Terminal, such as 'ln -s originalfile linkfile', but these are less functional, since you can't move or rename the originalfile without breaking the linkfile's association to it.

I was asking some time ago telling about the traffic that is coming in, dont know where it originate from. But now its coming with 800KB/s, and its KB not kb. I'm connected directly to internet, no firewall, static IP. I can see in little snitch some local computers. Wonder if I'm safe with OSX ? kernel_task process was so high, it attracted my attention

During installation, my graphics got all screwed up. You can see a screenshot of what's going on at this link: [URL]. I'm actually writing on the defective computer, so it's hard for me to see what's in the screenshot. Here's what I did so far. I tried removing half of the RAM first, then the second half, the problem persist. I rebooted on a different system, it's still there (so not software). I tried Hardware Test utility, it says everything is fine. I unplugged the Video Card, cleaned it a little along with the connectors, nothing. It happened DURING the update to 10.4.11 (not after I rebooted). I'm pretty sure I can take screenshots of it, so it's not simply in the connectors to the monitors. It happens on both my monitors (also when I unplug one of them).

I have read these forums/google for a definitive/best way to track down the files that are clogging up your hard drive. I've tried the Smart Folder route and for whatever reason it doesn't work as well as I'd like. What is the best way to do this?

Apple.com states that snowleopard is 64bit? And that because it is 64-bit it can run huge amounts of ram? Does this mean my Intel IMac (white) can run more then 3gb ram if I get snow leopard? or will I still be limited to the 3gb cause of my hardware?

New to the forum and unfortunately with a problem. Just got a new Mac Pro 8 Core over the weekend and Im having unusually high number of Kernel Panics (more in a couple of days then I have for the past 10 years with my other macs). I have tried to see if anything in particular causes it (ie Programs that cause the crash, time intervals, etc) and nothing can be ruled as the cause at least not that I can notice. It has happened wile using PS (CS4), Aperture, Google Earth, Safari and just in sleep mode. Here is one of the Kernel Panics along with system info. ps. The Mac started kernel panics before I loaded two additional hard drives and the wireless card (pci express).

I'd be interested in hearing what people are doing about backup with their huge iMac drives. Time Machine needs a drive somewhat bigger than their iMac HD, but not many of us want to shell out $500+ for 4T backup drive. I've been thinking of partitioning the iMac and backing up only one, smaller volume via Time Machine. Anyone else doing that?

Lately the menu bar will randomly throw in a huge gap between icons. Initially I thought it was a specific app, but now it's happening with all sorts of random icons there...definitely not the same icon each time.
The icons you see on the left are the ones I launched after the gap appeared.
Restarting my machine seems to be the only solution to removing the gap.

I've also tried trashing the com.apple.systemuiserver.plist pref but that didn't do the trick.

I have a huge MP3 collection, tag information is sometimes not correct, some tracks in a album are missing, covers are sometimes missing.
is there a program, that recognizes all albums with no missing tracks and good sampling rate, corrects the tag information and downloads the covers from the internet. automatically.... I would then delete all other songs and albums with missing tracks.

I checked my mail folder in library and the RSS subfolder is 4.32GB. It seems to me that Mail doesnt delete the previous RSS articles (although I have deleted them from inside the mail) hence the massive size of the folder. I tried deleting the folder, but then all the RSS feeds were gone when I launched Mail again. Is there anyway to reduce the size of this folder and delete the old articles without having to delete all the RSS feeds (and the folder itself?

I currently have a 2007 20" IMac the specs are 2.0ghz 4 gb ram 240 gb hd. While this machine does run all my programs it does so with a lot of lag. I have a huge itunes library (90 GB) and an even bigger iphoto collection. (Over 70,000 8mp photos). The issue is when I launch iphoto it takes awhile to launch (60 seconds plus) the same issue with itunes (30 seconds to load album artwork ect.). Don't get me wrong its not unbearable just not as snappy as I would like.
The question is will the top end 2009 IMac be a worthy upgrade or should I wait 1 more year. I would hate to spend 2400 dollars for something thats not noticeably faster. I tried the new IMac in best buy and it felt really zippy however they have like 90 photos and 15 songs in itunes. Is it just me or do these apps really slow down when you throw a ton of files at them. Anyways I am starting to ramble.

I have had my Powerbook G4 for a few years now and everything has been working well. When I turned it off yesterday everything looked normal. But when I turned it on this morning, everything was huge. All the tool bars, the screen,, everything is blown up. This is really inconvenient and hard to read... how can I return my Mac to normal and make everything small again?

Lately Safari has been hogging HUGE amounts of RAM after a while. After logging in on just this site to post this it has risen to 150MB! if I have several tabs open (2-4) it rises to about 600MB. This slows my system considerably as I only have 2GB total. Anyone have any ideas on how to fix this?

I remember when the late 2009 iMacs debuted and I went to the Apple Store to check them out. At the time, I thought the 21.5" was just the right size, while the 27" was monstrously large. I had a couple friends try to talk me out of the 27, saying that it was simply too big for home use.
Fortunately, I let the nerd in me out and got the 27. And after only a week of using it, the size no longer impressed me the way that it used to. Suddenly 27 was only normal, while the 21.5 became miniscule. Which made me think, just how big can desktop displays go before they're really "too big"? 30? 34? 40?
Is there even such a thing as "too big"? Or will we just adapt to the larger size like we've been doing all these years?

I have been reading that several people are seeing much cooler temperatures on their Mac notebooks and they think it's due to better graphics drivers with the update to 10.6.3. I however thought about the huge performance hit in OpenGL going from Leopard to Snow Leopard (probably same thing). So I decided to check my OpenGL results after installing 10.6.3. However, I didn't check my xBench results before upgrading to 10.6.3. I went and found an old result which shows 67 points for "OpenGL Graphics Test." My new result for "OpenGL Graphics Test" is 111 points. When I check the xBench archives, people with rev "C" MBA's with 10.6.2 all show OpenGL Graphics Test scores in the 60s.
If this is correct, we could all have some big improvements that really show huge effects on the MBA. It should help everyone running Snow Leopard. It should lead to graphics performance gains and lower heat due to graphics demands. Could someone else running 10.6.2 on a 2.13 GHz CPU MBA run an xBench test before the 10.6.3 upgrade? Then upgrade to 10.6.3 and run another xBench test. Then please report back here with your results for OpenGL Graphics Test and hope this result is great for all of us. I believe this would be a big improvement for the original MBA too?

I just replaced a 5400 rpm 320 Gb Western Digital (not the stock drive) with a Momentus XT in my late 2007 MBP, and I couldn't be more impressed. The eternal beach balls are gone. Granted, I've never had an SSD, but the speed boost from this thing is unbelievable. I didn't even do a clean install, just a restore from Time Machine. I didn't do formal benchmarks, but I did time my boot sequence before and after:
Old Drive
Chime to Login Screen: 46 seconds
Chime to launch Safari and open web page: 2:58
Momentus XT
Chime to Login Screen: 22 seconds
Chime to launch Safari and open web page: 38 seconds
So, the new drive can boot and open a web page faster than the old drive could get to the login screen. Altogether 2 minutes and 20 seconds faster. Not that I reboot very often, but it gives you some idea of how much faster everything is. I was so fed up with how slow my MBP was that I almost bought a new MBP for $2000, then I almost bought a 200 Gb SSD that wouldn't have had enough space for $340 (would have had to also buy an optibay and worry about losing hibernation or shock protection). So glad I just spent $130 and got a huge performance boost for very little money or hassle.

My master file is huge. How do I compress it so that I keep quality but that it is a manageable size for people to be able to buy and download from my website. It is a 1 and a half hour film and has come in at a whopping 80GB. Do I have some settings wrong here? I am using 10.1.1 Final Cut Pro X. I obviously don't want to store master files that big every time I make a film this long or is that just how it has to be?

I have a MacBook Pro that I got for Christmas, and ever since yesterday the Internet won't load on it. I've tried on my other computers (PCs) and the Internet is working (I'm on one right now). I've ran diagnostics for my Mac and it says everything is alright concerning the Internet, but if I try to access it it loads about 1/8th of the way and stops and stays there for hours. I've tried updating my Mac, but it won't connect to the Internet to update it.
