OS X :: Snow Leopard 64-bit Declare Inactive Memory
Oct 7, 2009
I have 4gb of ram in my MBP and am forcing snow leopard to boot into 64-bit mode by changing the one property in my com.apple.Boot.plist. I have noticed that if I keep my computer on for a couple of hours that over 2gb of my memory is declared inactive. The activity monitor does not show what is taking up so much memory on my computer. How would I be able to free up all this inactive memory so that my computer continues to run smoothly like it does when I do a restart.

I have a late 2008 MacBook Pro 2.4GHz with 2GB of RAM. I can't say it's ever been magnificently fast, but I always blamed it on the memory. I've always intended on upgrading it, just never got around to it. I've also been away for 6 months, so haven't been using my computer.
But today I've been trying to use Photoshop & it's hideously slow! Even the simplest task such as a desaturate command can take as long as 2 minutes! Admittedly on a large size document.
I have iStat in the menu bar. When performing these tasks I would assume it would display some sort of indication it's processing in the CPU. But it displays Photoshop only using at much as 16% CPU & the memory having 500MB of inactive memory? My brother had been using my computer away & was constantly complaining of the speed of it. He suspects it could be a CPU issue. Am I correct in thinking Photoshop should be using more CPU when processing a task?

If it's inactive, shouldn't it be free?

BUT.. I just doubled my RAM from 1 to 2 gigs. After a fresh boot and loading up Safari, Firefox, and iPhoto, and then CLOSING all of them and running no apps, Leopard shows more than a gig of ACTIVE memory, which even after sitting there for an hour doing nothing - does NOT go over to the INactive section. Why? I'm not asking why it doesn't go to "free". I know why.
My top command output:
PhysMem: 240M wired, 1006M active, 307M inactive, 1559M used, 489M free.
VM: 5579M + 374M 276396(0) pageins, 61(0) pageouts

Since installing Java 10.6.1_33, an online program I use will not function. The program says I do not have the correct Java update. Apple says to re-enable Java applets by clicking the region labeled "Inactive plug-in" on a webpage, but there is no region labeled "inactive plug-in". Everything worked perfectly before installing the latest update which was released yesterday.

i have a mac book pro ( 15 inch, 2.4ghz, late 08)
the memory limit is 4 GB. Is this an OS limit which will be blown away with snow leopard, or is it a hardware limit, which will remain regardless of 64bit OS?
other MBPs have 6 or 8GB limits, which makes me think they may be hardware related

I think I have an iMac G5 - flat screen, white covering. Right now I have OS X 10.5.8 & it's running rather slow. The processor is 2 GHz Intel Core Duo, Memory 512 MB 667 MHz DDR2 SDRAM. I want to upgrade to Snow Leopard 10.6.3 - tried today but says I don't have enough memory. How do I get more memory & what do I need to do it.

I'm running SL, haven't rebooted in several days.
I have no desktop applications running.
I'm on a MBP 13" w 4GB RAM.
Activity monitor is reporting 2.21GB memory active, 908.5MB wired. 106MB free.
Most unusual, is that I do not see any application in Activity Monitor using much real memory, yet it reports 2.21 GB memory active. I have had as much as 1.4GB swap space used, with no obvious culprit.
Any idea where the memory is going?

Just noticing the updated Flash Player on the new Snow Leopard update is taking about 660 MB of actual memory on my MBP.
Has anyone noticed and is this normal?

probably a slam dunk answer out there. I have been instructed to Open the Finder and Highlight MacIntoshHD. But when I click on the Finder, I see:About Finder, Preferences, Empty Trash, Secure Trash, Services, Hide Finder, Hide Others. What am I missing?

When I click on the red cross button of Safari to stop it, the window vanishes. But the application remains in memory, so when I click again Safari shows up immediately. This is the normal behavior, iPhoto doesn't. I mean the lightening dot under the icon in the dock disappears. So is there a way to have iPhoto behave like Safari? I upgraded memory of my MBP and there is space enough to keep iPhoto and others in memory.

I have three 16gb USB memory sticks that don't work correctly with Snow Leopard. Disk Utility is will only format them in FAT32 format and I'm unable to successfully copy files to and from the sticks.
They work perfectly fine under Windows in Boot Camp and also on my Windows based laptop. Sadly, I purchased them after I had installed Snow Leopard and I don't have access to another Mac with an earlier copy of Mac OS X to test them.
Is this most likely a Snow Leopard anomaly do you think or is it just that these sticks are not OS X compatible?

My Laptop runs slow and often spins when I open the browser or other apps sometimes and found the load average to be less than and also about 300MB free memory, till I notice swap as 40MB/256MB on iStat.
Questions:
1. How do I find out what process is causing the swap? The top does not show swap, and the vm_stat does not show swap either like vmstat does.
2. In the memory what does the wired, Active, Inactive memory mean? The only value that makes sense is Free.

Snow-Leopard 10.6.1 on uMPB with 4 GB RAM, 500 GB HD, 2.8 GHz IC2D, Mail (64-bit) 4.1 (1076) Mail is eating my memory over time and I cannot fix this problem. In long: I have been having trouble with Apples Mail ever since my SL upgrade but now it is getting to become VERY annoying. First, after upgrading, Mail would often hang when quitting (for up for 5 minutes) which would not allow me to shut off my computer. Now, in 10.6.1, when I open Mail, I can sit and watch Mail eat away my RAM. From 20 MB initially, it quickly hits 100 MB RAM then after a couple of hours of leaving it be, I can see that Mail is requiring 2.5-2.6 GB of RAM (Gigabytes!) constantly. At first, I thought this was due to GrowlMail not being compatible with 10.6, but even after updating Growl to 64-bit and reinstalling GrowlMail this memory problem still persists. Actually, after uninstalling Growl and all its applications (including GrowlMail) Mail keeps eating a solid 2.6 GB of my RAM. Continuously. This slows down my 4GB 2.8GHz uMBP and causes long sessions of spinning balls and delayed keyboard/mouse actions. Mail never lets go of the RAM only gets bigger up until 2.73 GB (highest I have seen before I force quit it through Activity Monitor). Once I Force Quit, Mail releases the memory and I am back to my fast mac. I found the following this at [URL] and after removing my RSS feeds from Mail and restarting mail, I am now running perfectly again --- Virtual Memory and RAM both less than 45 MB.

I just experienced something totally weird on my Snow Leopard. It starts suddenly dropping in the free memory (green) in my activity monitor with around 10 MB per second and the inactive (purple) memory grows. And it doesn't stop until it hits 10 free MB.

Currently, I have a 13" late 2011 MacBook Pro with 4gb of RAM. Right now, I only have 15mb of RAM free, and for some reason the rest is being used by an unknown process. I'll include a screenshot below

I have had my MB for a year now and I just noticed yesterday that when I have ichat (or any program open) and safari in the background the inactive safari window fades to transparent when not in use (when another window is on top of it). Is there any way to disable this? Or has anybody else had this problem. I don't remember turing on an option like this.

A couple weeks back, we switched from exchange 2007 to exchange 2010.The only change required on the OSX mail client was to change the server address.I have two macbook pros, one is a 2GB early vintage intel, and the other a more recent 4GB model.Both of them are configured for access to the exchange server.Both are running 10.6.Once the change was made, both clients started using huge amounts of memory.This isn't a leak, as is reported in some Lion threads, because it eventually comes back down again.When you start the client, it might use about 150MB of RAM.After a while I have seen as much as 1.6GB of RAM usage on the 4GB machine.If you take the exchange account out of the mix (disable it in preferences) the client consistently stays at about 75MB of RAM.The peak isn't limited by the client as far as I can tell -- it basically uses up all free memory and drives the system completly nuts.Many of the applications no longer perform well once they are subjected to memory starvation, and this includes the mail client itself.
I am now running the activity window with Mail to see if I can spot a pattern, but in one case I watched Mail's memory usage grow in Activity Monitor with nothing in the Activity screen.I aso tried creating a new account instance on the 4GB machine, but without any cached data the behavior was far worse.It very quickly consumes the entire machine and doesn't seem to return to normal.I am firmly convinced this is a side effect of changing the exchange service or one of the exchange settings, if for no other reason than the behavior is new on two systems.It's still unforgivable for the Mail client to do this -- if it can consume all available memory then it needs to monitor itself and defer or break up what it is trying to do.I am a great fan of this mail client but this is so unusable that it might force me back to outlook running in a VM.

We all know that you could never have enough memory in our computers, so I have a fairly simple question to ask. When OS 10.6.0 comes out a.k.a. Snow Leopard, will all the Intel Core 2 Duo machines have an increased ram capacity. It looks more and more everyday as if 4GB is becoming a standard in machines and all across the board (Dell,Hp,Apple) computer these days are handling 8GB of ram with ease. So does anybody know if when Snow Leopard comes out, will there be a potential for my MacBook to contain 8GB of ram.

Well not so much a leak but since upgrading to Snow Leopard I've noticed that over time, a big chunk of my RAM is being siphoned off into a process called OSMServer. Does anyone know what it does and why? And more importantly how to stop it doing it? It's currently using over 1GB of my 4GB RAM and making the machine run like treacle.
The only way to clear it seems to be a full shut down and restart. Which is fine for a while until it fires back up and starts gobbling RAM again.

I have installed Office 2011 incl. Outlook on my iMac.
But when I try to send a Mail from some App's, Mac-OS is always starting the Apple-Mail. How can a change this?
I also running Paralles with a W7-Virtuell Partition and the same rusults. I do not want to install another Office-Package under W7.
When I want to write a Mail from Inside Paralles, I also want it to use Outlook under Mac-OS

... long time reader, first time poster!! So I'm doing it. I'm switching from PC to Mac. I've been waiting for a while now and the new MacBook Pro's have convinced me. I'm buying the 13 inch this week.
However I'm slightly worried about the upgrade to Snow Leopard in September.
My question is if I buy a new MacBook Pro this week and upgrade from the current version of Leopard to Snow Leopard will it be the EXACT same as the version of Snow Leopard that ships with new MacBooks after September?
Is the upgrade just the same as the full software version available post September? Does the upgrade it just detect if you have the previous software and installs as if it were the full? Or does it just "patch" things depending on what's different from previous versions?
I can wait till after Snow Leopard is released in September 09 if it is different to Leopard upgraded to Snow Leopard.

I have a Snow Leopard Install Disk for the 13-inch Macbook Pro model.I also have a 21-inch iMac. I have OS X Lion installed on both. I have Snow Leopard installed as a partition on my Macbook Pro, which I installed via the install disk. I want to do the same thing for my iMac but I am unable due to (seemingly) my install disk is for a Macbook Pro and not for an iMac.
