OS X :: Snow Leopard And 16gb USB Memory Sticks Not Working?
Sep 2, 2009
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?

Last night Lloyd Chambers of [URL] tweaked his DigLloydTools app (DLT) that we use to test memory throughput. It's now more accurate. The bad news is that it showed that when we put 8 sticks of memory in the 8-core 2.26GHz Nehalem, our throughput for memory read/write (memmove) dropped by 1/3. It turns a triple channel memory bus into a dual channel memory bus.
Specifically, in our test, the combined read/write throughput dropped from 9261MB/s to 6195MB/s when we went from 6x2GB to 8x2GB configuration.
Now, don't panic. That doesn't necessarily affect real world app performance unless the particular app you are running is saturating the memory bus. Which apps saturate? I don't know yet. I'm running our complete real world test suite including Pro Apps and 3D Games in both the 12G and 16G config. If I find anything that's significantly slowed by the 8x2G config, I'll post it here as well as on Bare Feats.

I have those sticks for my psp and the work great. PS3 sees them perfectly and the old pc I had, but for some reason my brand new imac doesn't see the memory stick I put in.
Am I putting it in the wrong way or do I need to buy something extra to get them to work on my mac?

I am going to buy an Imac soon. Most likely the with 4 gig ram. I was just wondering how many memory slots does an 24 inch Imac have. Because I have 2 one gig ram sticks that I wanted to add to it and didnt know how many free slots it would have.

I run parallels a fair bit for research and my MBP is pretty slow. Took it to genius and he said to get a memory upgrade to 8GB. However, I'm reading everywhere that it can handle 16GB and the Crucial says it is compatible (only £100 ish for this so seems a pretty good deal). All well and good- but will this invalidate Apple care as the max Apple state it can handle is 8GB? Or.....is 8GB going to be enough anyway?

"Photoshop CS" and "Acrobat 6.0 Standard" suddenly stopped working in my iMac, apparently after I upgraded it to MacOS 10.6.8 (the latest version of Snow Leopard). Both programs had worked normally until that OS upgrade. I deleted Photoshop CS and tried to re-install it from the original CD, but the installation never proceeds because I get an error message entitled: "Install Adobe Photoshop CS quit unexpectedly". This is the full error message:
Process: LaunchCFMApp [1516]
Path: /Volumes/Adobe(R) Photoshop(R) CS/Adobe(R) Photoshop(R) CS/Install Adobe Photoshop CS.app/Contents/MacOS/Install Adobe Photoshop CS
Identifier: com.MindVision.InstallerVISE

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

Quicklook has stopped workingon my MacBook Pro OS 10.6.8. Pressing the space bar on a file yields nothing. Is there a way to update or reset it so it starts working again?

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?

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.

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.

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

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.

Firstly I am sorry if this has been posted before, but I did have a look at the Snow Leopard FAQ & a browse through the current topics. And secondly, I am also sorry if I am not using appropriate computer language to describe certain things. I have a 17 inch Macbook Pro I bought in the middle of last year. Before Snow Leopard. So when Snow Leopard came along I went for the upgrade without looking around at compatibility issues with certain software.
So after the upgrade, my EyeTV didn't work, and neither did my internet (I use the ones with the USB stick). So I couldn't even go online to get my EyeTV update. So in my (brief) panick I re-installed Leopard, which wasn't a great idea I guess, because all of a sudden my HD space went down to 50GB from my 500GB of storage. Now I know I didn't have the full 500GB since I did have some photos, music & videos on board. But surely 50GB remaining is quite ridiculous. I think it probably performed a Time Machine backup for me.
Anyway... that was awhile ago. And I was happy to carry on with what I had. But now I think I would like to try what Snow Leopard has to offer. But with only 18GB of space remaining, I think the best option might be to reformat and start over. What do you guys think? My other option is to try to delete as much as I can spare to make room for Snow Leopard. Sorry if this question is a silly one, but I have done a lot of things with my iPhone & with this Mac without thinking & asking first & I have always regretted it. Thanks for any help or suggestions you all can offer.

I have mac mini (early 2009) running leopard and want to upgrade to snow leopard. I've bought a disk from a local store and when I try to install I get as far as 45 minutes to go when the installer reboots the computer and says it will continue to install after reboot. So it reboots kicks the disk out and reboots back into Leopard. The Apple site says it is probably a bad disk, so I got another one, still does the same. Apple also says it might be the dvd drive, I have no other issues with the drive, it installs the original leopard disks without problem, it reads video dvd's without problem, it verifies the snow disk as perfect.

Anyone else having this problem?
My HP A-I-O printer is not working under SL. Tried deleting the printer in Prefs. and reinstalling the drivers a bazillion times. I even went out and bought a *new* HP printer and I'm experiencing the same problems.
