MacBook Pro :: Limiting Size Of VM Swap Files Possible?
Jun 13, 2010
I have the new 15" with SSD (80 GB Intel) and HDD (500 GB). I have put System and Apps on the SSD, while the user's home directory is on the HDD. So far so good, performance is great. But I have run into the problem of getting the "Memory on the startup disk is too small" warning twice. That's a pretty unpleasant experience, with apps freezing etc. Of course, nominally my startup disk (the SSD) is far from full, since the apps occupy maybe 30 GB and the System maybe 15. I should have over 30 GB of available disk space. So what happened? I found out that the culprit is virtual memory. Somehow my system at some point thought that it needed a lot of VM (around 40 GB), and the VM daemon started writing swap files (up to 40 of them!) on the startup volume, until it got full. After quitting some apps, somehow the situation gets corrected and the system automatically reduces the number of the swap files again.
What are my options to keep this unpleasant problem from occurring again in the future? Here are the ones I can think of:
1. Move the VM directory to HDD. I don't like to do this because it would significantly hurt performance.
2. Create an additional partition (~10-20 GB or so) on the SSD, then move the VM directory to that partition. This way, I always know the max. size of VM and I won't be surprised. Disadvantages: I will need to repartition the SSD and re-install system and all apps. And I may be wasting precious space on the SSD.
3. The ideal solution would be an option in the VM daemon to limit the total VM size. I have perused the man pages, but I can only see an option to set the size of each individual swap file, not the overall VM size.
I saw an interesting post today by pgharavi who says he is using SMCFanControl to set the max speed of his fan to 4000RPM:Quote:From the terminal: /Applications/smcFanControl.app/Contents/Resources/smc -k F0Mx -w 60e0
I obviously gain a few degrees C when limiting to 4000, but at least my MBA shuts up.Not to question his knowledge but have others tried this and does it really work? might not go so far as to set the fan to 4000 (but I might). Given all the thoughts on Coolbook, what do you all know/think about this? Safe and effective relief from fan headaches?
I set up a new user account for my daughter on my computer, an account running Simple Finder. I would like to restrict all applications, except one, because this is for homework.
When I specify the application that is allowed in the parental controls, and then attempt to open it from her applications folder I get the message "You do not have permission..." I tried putting the application in the Shared Folder but that did not change anything.
All my smaller files show up as 4kb in finder. I know this is because on HFS+ that is the minimum allocation for a file, but it really doesn't help when trying to get a sense of how large files are when you're thinking of deploying them to the web, or glancing to see which are longer/which have been changed etc. is there any way to set Finder to display the size of files based on how much data is in them.
The standard HD that came with my Mac Pro was a 320GB which I thought would be big enough. I also added a 500GB in bay two for all of my work files. As I migrate all of my files onto the Mac now, I'm realizing that the 320GB is quickly running out of space with all the photos, music, etc. and my work files currently take up about 50GB so the 320Gb would have been better for that. Is there an easy way to swap my 320GB boot disk files with the 500GB data drive?
I have noticed that some of my programs when I run them take a massive amount of cpu usage and make my computer run very hot. This question seems like a stretch to me but is there any way to limit the amount of processing power a certain program uses? I don't really care if the program takes a longer amount of time to complete what it needs to do, I just don't want my computer overheating.
To reduce the signal to noise ratio,please do not respond to this post asking questions of why I want to do this or with opinions about the validity of the task.I have a mid-2010 MacBook Pro Core i5 and I am consistently enraged that a computer this powerful is always lurching along when I am trying to do multiple things at once.I would like to limit the amount of RAM/CPU available to applications on a systemwide basis.All mobile OSes institute this policy (except for Android and its runaway memory munching) and this is what makes those system react so quickly.I know about nice and freezer but these solutions require constant tweaking for each process run. I would like a solution that is applied to every process, systemwide, if that is possible.

My home network consists of three computers connected via a Linksys wired router. Is there any way to limit (or disable) the connection speed to a particular computer? I'd like to be able to selectively limit/disable the connection, without having to remove the ethernet connection on said computer. I can access the router status and enable/disable the connection for the entire network, but I can't seem to selectively limit/disable a particular connection.
My understanding of Documents and Data in iCloud preferences is that when turned on, all of my iWork documents will be synced. I don't want to do that because some documents contain sensitive data. Is there a way to restrict syncing to a selected folder of documents?
I have one two-hour file in mp3 format and one three-hour file. These are radio shows, so no music or anything, just talking. Now that I have the files, I want to get them as small as possible without making them unlistenable. What program can I use to reduce them?
I started a transfer of a large file, but it did not finish, but the DMG file is showing me the 7 GB Full Size of the Finished file! But I know that the file stopped midway and only transferred half of it, around 3.5 GB. Is there any way to see in the Finder / Inspector the real size of this file which should only be 3.5 GB and not the 7 GB it is displaying in the Inspector?
I'll be getting an 80GB Air this week and I'm trying to gauge how much space I'll use up. Right now I have about 80GB of space used up on my hackintosh, but allot if it is junk I probably won't transfer over. Is there a way to look at all the files on my computer in order from largest to smallest?
Is there a way to list every file on the computer by size? I'm trying to see what's taking up so much space. I have a 15" unibody mbp with a 320 gb hd and I only have like 30 gb left ... i use fcp and tried cleaning out all the capture scratch folders i don't need . but i want to list it all if possible.
I'm used to being able to find out the file size of a group of files I've selected in Windows' Explorer or Desktop by right-clicking one of the selected files and selecting Properties. I haven't been able to find a way to do anything similar in OSX Snow Leopard. Is it possible to find out the size of a group of user-selected files?
So I know in Leopard and probably any OS for Mac's you can compress your files, but is there any way to compress them even more? I had a file that was 321mb's and when I compressed it, it brought it down to 317mb's. Obviously that didn't do me any good. Does anyone have a program or another suggestion?
This is one of the things I haven't figured out how to do yet on my mac. I miss this feature which was so easy in windows. Select multiple files and click properties and you get a file size count. If you do the same thing on a mac you get a number open for each file. If you need a cumulative total quickly its a pain in the butt to add each file.
What am I missing here?
Also, any way to display file size at the bottom of a finder window? When you click a file, it says "1 of X selected" and the amount of hard drive space free which is cool, but file size at the bottom would be nice to have.
I have exported the albums from iPhoto. I want burned to the desktop--which should return the photos to their original file size. When I burn to a DVD via the Burn folder--the photos are compressed.
They are usless to me in this compressed state. I need the full size files of the photos to print quality pictures and to load onto a PC for other work requiring large sized files for quality printed pictures. My DVD does not show up on my desktop so I can just drag the folder to the DVD to burn it I have to use the burn folder.
does anyone know how to select a group of files to then get the total size of the group. ever since i upgraded to snow leopard, whenever i select a group of files and then click on info, i get separate windows for every file and then must add them up separately.
If I have a bunch of files and I want to see the combined size of these files, on windows I would simply mark each file, right click one of them and hit properties. If I do that on my new mac mini and then hit More Info or whatever it says, then it just opens the info window for each file - it doesn't give me one where it says the combined amount of files, size and such. Is it possible to do this somehow?
I don't have enough space at my Time Capsule, and I noticed that I have backed-up some silly big folders like Downloads. So I assigned them for not to take backup. But time machine already took backup of them and keeps space in Time Capsule.
I still have the older style 2008 LED MBPs where you have to remove the top of the laptop with jewelers screwdrivers and whip out the torx screwdrivers to replace the hard drive. Ram is easy on the older laptops.
done some searching and looked at the sticky but I'm still undecided about what size to get. I had originally decided on a 17inch MBP but now I'm leaning towards getting a smaller MBP and a new iMac. I'm not looking top of the line but I would like to be able to play WOW on occasion and do some on the road photo stuff (but nothing to the level of pixel peeping). I'm looking at the faster of the 2 13 inch MBP variations versus a 15 inch with the same basic specs. What I'm worried about is the 13 inch having enough horsepower to do the simple photo and games that I'd like it to do.
Right now I have basically the same setup that I'm looking at doing again. A 20 inch iMac G5 and 12.1 inch iBook G4 both bought last half of 2005 (just after the iBook was updated - remember my order was delayed waiting on the new specs). The iMac can run WOW fairly well BTW, just lag evident in the trade district in SW.
TIA and hopefully this isn't too redundant with other questions.
A replacement to my girlfriend's pre-unibody 2.5Ghz (4,1 with the 8600GT) macbook pro is soon to arrive (thanks Applecare) and I'm really hoping I can just "hot-swap" the old (but newish) 500GB 7200 rpm HDD (bootcamp partitioned ) into the new unibody replacement. Does anybody think this will work? Will there be EFI/hardware issues?
FYI (this is due to 4 ongoing graphics/screen issues)
