HT3918 Does Snow Leopard use all the ram installed, I know that Leopard didn't.
Does Snow Leopard use all the ram installed, 10 gigs in my case. Leopard didn't.
You should be OK with that much, however, besides the basic needs of the OS, it will depend on how many and which applications are open and how memory intensive they are. Someone might easily get away with 4GB and someone else might have trouble with 16GB.

Oracle using all the ram on my server

Each time you read a file from disk, whatever was read is cached by the system; when the file or program is no longer in use, the memory is marked free for the system to recover for other purposes but as long as it remains in memory the next time you need to access that disk information it's simply read from memory.
The more RAM, the more disk data is kept around and the faster your machine will operate until that memory needs to be recovered or you reboot (or otherwise flush the disk cache.) -
Anyway to fully use all the ram in bootcamp?
is there anyway to fully use all the ram in bootcamp? where now only up to 2.17 usable from my 4gb ram in macbook pro or this is normal?
I'm using window 7 with 32bit.Use the 64-bit Windows 7 to get the full amount of RAM.
It's a limitation of 32-bit Windows in conjunction with a limitation of Apples Boot Camp.

Photoshop isn't using all the ram that I have.
I recently installed 8gb of RAM into my Macbook Pro so i could increase the performance of Photoshop. Before using Photoshop, I increased the the "memory usage" slider up to 75% but after I do that, its only using 1gb worth of RAM. Am I doing something wrong?..I would appreciate of someone could help me out.
Did you double-check that you have not set it to run in 32bits mode? (right-click on the Photoshop CS5.app icon, select Get Info, and see if start in 32 bits mode is not checked.) http://kb2.adobe.com/cps/828/cpsid_82824.html

Hi!
I"m wondering, I have FCE exporting a video while iMovie is importing one. I see that my Macbook is only using 750 mg of ram. How come it doesn't use the whole 2 gigs?There are no options that cover RAM usage in the Energy Saver System Preferences. In fact, with a MacBook, you can't even select "better performance" usage of your processor. This functionality is built-in to the processor and there is no GUI for adjusting it in Mac OS X. So, there are no options you can configure to alter the amount of RAM used or not used with Mac OS X, it's all automatic.

I am running 10.5.8 and want to make use of the icloud changeover, I understand that I must first buy snow leopard 10.6 and then buy lion 10.7. Do I buy these as upgrade versions or full versions? I am not very techie, thanks for any advice.
A 10.5 era machine is better left on 10.6.8
I don't advise upgrading it to 10.7 as you'll have to buy all new versions of software for a older model machine, some are not ready yet and some of your third party driver software may not be available for your other hardware.
10.7 is slower and requires 4GB of RAM actually.
10.8 is being released this summer and it won't run on certain older graphic cards, so shortly you will be behind again.
Save your money for a new 10.8 machine. IMO
These rapid OS X upgrades are for those who like to be on the cutting edge and can afford to buy new hardware often, you didn't even upgrade to 10.6, so your not that sort of person obviously.
But you do need to upgrade to 10.6 for security issues and faster video. It will run your 10.5 Rosetta software, but 10.7 will not.

I am running Firefox 18.0.1 and the plugin-container is using all my ram, have tried altering dom.ipc.plugins to false but makes no difference. Any advice please
plugin-container.exe is used to run Flash and other plugins so if they crash they do not take down your main Firefox session. But... I don't think memory usage would be that different if you tricked Firefox into running Flash inside firefox.exe. (There was a thread with the trick, but I can't recall the details. It was not a regular Firefox setting.)

Greetings,
I hope this email finds you well. I bought my iPhone on December 1st, 2012 with a track order W459517623. When I first bought it, it was meant to use all the services provided by Great Apple including the new LTE service as a main service for such device. Now I just realize that such service does not match with the model I have, as per this link:
http://www.apple.com/iphone/LTE/
Model A1429
(GSM model)
Saudi Arabia - Mobily
The model Apple sent is A1428
I believe that such service should be provided to my devices too. Also, Apple always find best ways to solve such queries.
Please advise me
Thank you and Regards,
AbdulrahmanI'm assuming you bought it via the Apple Online store. Contact them. Use the Contact Us link at the bottom of the page. Did you buy the phone from the store in the country you intend to USE the iPhone? If you bought the phone in the US store and intend to use it OUTSIDE the US, you only have yourself to blame, as they shipped the CORRECT phone for use in the US.

Hi My battery on my macbook pro keeps running low on power very quickly and I have to keep recharging it. This has never happened before. I have used all the power saver options, but it keeps happening. Can anyone help. The battery seems to be losing power even when it is turned off.
Hi BigThinker,
How old is your Mac? If it is an older one, then the battery may just be dying. You can check by clicking on the Apple in the upper left-hand corner, then clicking on About This Mac>More Info>System Report, then click on Power (about half way down the list). At the top of the resulting display, you should see the following type of info:
The Health Information will tell you if your battery is going to need replacement soon. If it says Normal, then it is not the battery.
Cheers,

Aperture and Lion using ALL my ram
Using Aperture on a Macbook Pro (2008) Intel Duo Core machine.
Worked great with Snow Leaport, but now with Lion, eats ALL of my ram in minutes.
Forget about using any plugin's or external editors, but Aperture itself takes it all.
I have 4GB total in the machine.
If I upgrade the ram to 8gb, will that solve the problem, or does the ram just continue to be sucked
up by Aperture unil it's all gone no matter how much I have in there?
Thanks for any advice.There is an entire thread on bugs in the Aperture/Lion combo here
https://discussions.apple.com/message/15996854#15996854
In a nutshell, Aperture is buggy under Lion. Net result is that it is not usable with 4 GB or less and maybe even 8 GB is not enough. -
I am so upset because i didn't research enough before upgrading to Lion. I can't use a lot of my pograms i used all the time now. I want to go back to where i was before Lion. Is there a way to do it without costing me more money?
I didn't say the price was necessarily a drawback; just thought I'd throw my two cents in if the OP didn't want to purchase more software (as he/she alluded to in the first post). Even if it's a small cost (in your opinion), the OP said they didn't want to spend any more money. I didn't think about buying it on ebay; but that's a good idea. Just keep in mind that the Parallels free phone support is only good for the first few months after purchasing a new copy, so if you're buying a used copy, you won't get free phone tech support. I think they have per-incident support once the free period is over, though. And they probably have forums you can use to troubleshoot any issues.
Parallels can also cause a slow/laggy OS, which could be seen as a drawback. Of course, you could always purchase more RAM if the computer does lag, but there's another cost. I'm sure it doesn't happen to everyone, but it can happen, that I've seen. Especially if the computer you install it on is an older one that barely meets the Lion system requirements to begin with.
I agree with you; I purchase hardware and software for the future. If my new iMac won't run software from 2004-2008, I guess I'm upgrading. I understand when people don't want to upgrade, but after so many years, it's not really a choice.
I prefer the dual-boot method; it's cleaner (in my experience) than a virtual machine software program, and causes fewer issues with the main OS installation. It's really just preference, though. The OP can try both ways and decide which is preferable for him/her.
What I posted was (as I said in my first post) just my suggestion. I wasn't trying to override what you said about Parallels being the answer; just adding a new answer that I didn't yet see in this thread, in case the OP wanted an alternative. Maybe I mis-read the defensive attitude in your post, and if so, I apologize. But you seemed to be defending something that I wasn't truly even attacking to begin with. I feel that the best choices are the most informed ones, and with more options, the OP can find the best answer for him/her.
Have a nice day! -
