i am buying a new macbook pro but i want to fit my own ram memory and solid state hard drive , will apple permit this without voiding the waranty.

yes you can do it and not void the warranty. Those are the only hardware changes that Apple permits. Instructions on how to upgrade the ram and remove and replace the hard drive are even included in the owners manuals for MacBook Pros.

Installing additional ram memory

I am trying to install memory in my Mac Pro, but some of the risers come upon the hardware configuration panel as empty. I have moved around the memory modules and they all work, but just not when they are all installed at once. I have two sets of 2 gb modules and four 1 gb modules. Two of the 2 gig modules are are Centon and two are another brand. All of the 1 gig modules are exactly the same. Currently, I have 4x1GB modules installed and 2x2gb modules installed. My computer is reading the 2 GB modules, but only reading two of the 1GB modules. Here's my Mac configuration:
Model Identifier:    MacPro2,1
Processor Name:    Dual-Core Intel Xeon
Processor Speed:    2.66 GHz
Number Of Processors:    2
Total Number Of Cores:    4
Memory:    6 GB
Bus Speed:    1.33 GHz
When I putt all four of the 2GB modules in the first two slots and the four 1GB modules in the last two, the computer read the 1 GB modules but one of the 2GB modules????? When I removed all of the 1 GB moduels, the computer then read two of the 2GB modules. I am totally confused. I have tested all of the modules and they all work in one configuration or another, and I've checked all of the slots and they work too. Any suggestions on what I should try next?
thanks

Hi, this may or may not resolve the issue:
MacBook Pro: How to remove or install memory:
Additional notes     For best performance, fill both memory slots, installing an equal memory module in each slot.
     In Mac computers there is a hardware component known as the "RAM Equalizer". The function of this is impeded when the memory slots are filled with unequal memory quantities.

Problem installing 512mb RAM in Macbook Pro.

Hi,
I hope someone can help me, I have checked other posts and nobody seems to have the exact problem that I have after installing RAM.
I installed a Crucial 512mb module in my Macbook Pro which already had a factory installed 512mb module in one slot.
First time the Mac started up ok but it did not recognise that extra RAM had been installed. I reseated the crucial module and the Mac would not start, just a pulsing power light and a black screen.
I installed one module at a time and the Mac booted correctly with both the Crucial Ram abd the RAM it shipped with.
When I put in both Modules it will not boot, I switched the slots and made sure that modules were inserted correctly but no joy.
Sorry for being so long winded!
Macbook Pro Mac OS X (10.4.6)

Thanks guys,
It just seems odd that both modules are working correctly when they are installed on their own and there is no boot when they are installed together.
As you stated it may be that the specs are different but I checked and all the info seems the same.
I'll just go ahead and send it back to Crucial for a replacement.
Thanks again.

Hi sethfrommedford,
If you are having an issue with installing the iCloud software on your Windows computer, I would suggest that you troubleshoot using the steps in this article -

While the article addresses iTunes installation issues, the steps are also valid for installing iCloud software.
Thanks for using Apple Support Communities.

Installing new ram memory

Hello All,
I have recently installed a new ram into my mac. I installed a 2GB ram and put it into the right slot. I left the memory in the left slot there. Everything seems to be running fine (and faster) however everytime I close the lid to my mac and reopen it, the whole computer starts up as if I have shut it down. I never shut it down though. Can someone tell me if I did something wrong and if I can fix it?
Thank you so much!

As for your last two question I don't really understand them...
OK.
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
2nd one, since you have a Laptop, I was wondering if it was running off the Battery or plugged into AC with the charger?

Not enough Ram memory and cannot save due to a program error in photoshop cs6

Hi, I'm currently a beginner at photoshop cs6, and I've been using it since december last year, mostly to draw stuff and it has worked fine with few to no errors at all.
However, recently when I've been drawing, the same message keeps popping up over and over again "Can't use (tool) due to the computer not having enough ram" followed by either "cannot save due to program error" or, it just simply crashes.
This is obviously a something that worries me A LOT since at first, I thought that it was just a small error, but recently, it's been like this for several day s and I've been forced to re-start the computer (and photoshop) countless times... It really slows down my working progress and is VERY annoying to deal with.
As a beginner though, I don't really know how to fix this. I've been trying to look up some answers on this site, but I've just not found any answer yet...
I'm currently using photoshop cs6 that's up to date and I've got lots of memory left on my computer, so, I'm wondering. What exactly is the cause of this problem, and how can I fix it? Please answer as fast as you can.. I'm getting a bit desperate...
Oh, in case you're wondering, they're all saved as PSD files and every single one of them has about 15+ layers on them.

It would help if you could list a few things:
1. Your operating system
2. How much physical RAM do you actually have in your machine?
3. Under Preferences > Performance, have you allocated "Scratch Disk(s)"?
4. Also under Preferences > Performance > Memory Usage, what is the "Ideal Range" listed there, and what % is "Let Photoshop Use"?

Upgrade or Archive and Install option on new and almost empty HDD?

My Macbook has recently come back from repair with a new HDD fitted after the original failed. It has Tiger and iLife 6 installed plus a couple of 3rd party applications (PhotoPresenter and Onyx) but apart from the configurations for my Airport base stations there is not else on it yet. I have a home wireless network that I set up from this Macbook comprising of an Airport Extreme and an Airport Express connecting wirelessly and I don't want to risk losing my internet connection. Is it still considered to be the safer option to install Leopard using the Archive and Install option or would it be ok to choose Upgrade which looks easier to do and would take up less space on the hard drive? I also want to upgrade to iLife 8 at some point...should I do that first?

Hi 12frets56;
If you do the Upgrade and have problems, you can always do the Archive & Install later. That is part of the reason I suggest do the Upgrade first. It is fast and easy. If it works for you as it did for me you are done quickly.
I also start with a clone of my current system first that I test to be sure I can boot from it. So far I have not needed it but it is alway nice to know that you can get back to the current system just in case.

Write / read files to RAM memory

Dear all,
I want to write a text file to RAM memory and after read it from RAM memory.
Why? Because, I want to read my text files quickly, in short time.
if I use default method for reading files it take long time for reading the file and for write the file.
But, if I use write / read files to RAM memory, I can read my files quickly and read my files from RAM for processing and write my files to HDD.
Can you help me?
I searched on the Internet this problem and I did not find any one solution.
From my searching on the Internet, I understand that Java can not do that.

The problem with this program is that it load 1 minutes, but I want to load a second.
Here is my java code:
import java.io.*;
public class File {
public static void main(String[] args) {
// Start to reading the file
      try{
    FileInputStream fstream1 = new FileInputStream("big.txt");
    DataInputStream in = new DataInputStream(fstream1);
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
    String strLine;
    while ((strLine = br.readLine()) != null)   {
// Start to replacing method
    String strreplace = "%";
    String result = strLine.replaceAll("a", strreplace);
// End of replacing method
// Start to writing to file
      try{
    FileWriter fstream2 = new FileWriter("out.txt", true);
        BufferedWriter out = new BufferedWriter(fstream2);
    out.write(result); // Write to file the result
    out.close();
    }catch (Exception e){
      System.err.println("Error: " + e.getMessage());
// End of writing to file
    in.close();
    }catch (Exception e){
      System.err.println("Error: " + e.getMessage());
// End of reading from file
} // Here is the end...Please to do the following steps:
1. Copy my code;
2. Download text file from: [http://norvig.com/big.txt|http://norvig.com/big.txt]
3. Open the text editor and select all text (Ctr+A) and dublicate the text 10 times for creating a big text file (30-40 MB);
4. As a java developer, You know what to do next.
I'm waiting your solution.

Reader won't install; not enough memory

Adding memory and upgrading to Leopard on PowerBook G4

I have a PowerBook G4 with OS X Panther and am considering upgrading to Leopard. Installing Leopard requires at least 512MB of memory and I only have 256MB. I've read that PB's can be picky with the type of memory installed and I'm looking for advice on making an informed purchase.
According to my manual the maximum I can have is 1.25GB and it says I need PC2700 DDR 266 type RAM. I also read somewhere on Apple that my PB requires PC100 type RAM, so which is it, or can it actually take either one? And are the GHz a crucial factor in determining what type I need? How do I find out the GHz I have on my computer?
Also, does anyone think upgrading this computer (it's 5 years old) is worth it? It only has 23GB of space left which I know Leopard will use a lot of just to install. Would it also be worthwhile to add more hard drive space (I'm considering an external hard drive to store photos and documents to save space), or in the long run will I be better of getting a newer mac? Physically my PB is in great shape and it still looks brand new, it's just outdated, but I don't want to put a lot of money into it if it's not worth while for long term use.
Thanks for any help you can give and sorry if these questions have been answered already. I wasn't having any luck finding specific info on this.

If your PowerBook is the 867 Mhz model or 1 Ghz model it will take "a single 200-pin PC2100 DDR SDRAM SO-DIMM memory module.". If it is anything greater it will take "a single 200-pin PC2700 DDR SDRAM SO-DIMM memory module."
You can find what processor you have by clicking the Apple logo on the top left hand corner of the screen and clicking "About this mac"
Basically, 1 GB stick plus 256 mb soldered memory = 1.25 GB Max.
Is it worth it? Well, since you probably can't buy a new laptop for anything close to a Leopard/RAM upgrade I'd say it is worth it. But if you are considering RAM+External HDD+Leopard you could be well onto your way into the price range of a second hand Intel Laptop, any of which would be significantly faster than your PowerBook.

Upgraded my iMac 2011's Memory and now it won't boot properly

Hi,
So, today i upgraded the memory of my 27" 2011 edition iMac, the ram i used is two sticks of 1333mhz DDR3 4GB ram, to upgrade from the conventional 4GB to 12 GB as my iMac was struggling due to lack of memory when loading certain programmes. I installed the Ram fine and had no issues with that, I then booted my iMac up and the ram had registered fine, no problem. I then opened up google and this also worked fine but when i opened other programmes or at least, I tried to, the unit just crashed and restarted itself, well.. attempted to. Now, whenever I try to turn the unit on it gets to the apple and the loading bar, loads 3/4 of the way and then doesn't boot and restarts the process. I have tried to remove the RAM and just use the original but the problem still persists which i'm presuming is due to the iMac believing its running 12gb when I put the original 4GB back in as obviously that's what previously registered. I've seen one of these posts from a couple of years ago but it didn't get answered so if anyone has any thoughts as to how to fix this problem it would be greatly appreciated, thanks in advance!

Do you have a link to Amazon RAM?
Macs are very, VERY PICKY about the RAM specs they need.
Most common electronics retailers and wholesalers do not usually have the correct RAM and specs Mac computers need.
Here are the correct specs for RAM your 2011 Mac needs.
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Also, the timing latency has to be low...9ms or less.
Here is known good and compatible RAM from OWC (macsales.com)

Memory and HDD expansion on Satellite 1805-s203

Satellite 1805-s203
Intel Celeron 800 MHz
128MB expandable to 512MB
15 GB HDD
I've recently installed 256MB of memory and there appeared to be only to slots for memory. To expand my memory to 512MB do i have to remove the 128Mb memory and replace it with a 256?
Also, how else can i upgrade this laptop? Could I increase the HDD? How much could i increase it with 512MBs of memory?

Hello
It is not easy to find precise info about older notebook models. According the notebook info it can handle with max 512 MB RAM. Compatible RAM module is KTT-SO815/256 256MB Memory- (Kingston). Using two of them you can have max RAM and notebook will run much faster.
About HDD is not easy to say for sure but I think you can upgrade to 30 or even 60 GB, but 30 should not be problem.

Should i quit application to have better ram memory?

should i quit application to have better ram memory and a better performance or on 10.4.2 or is that ok to close the windows but not quit the programs...
thank you
hubert

Mac OS X tries to optimize performance by caching a whole lotta stuff. What that means is that if you quit a program, you might not necessarily get all that RAM back right away because OS X will keep some of the data around in case you use that app again soon. This is not necessarily a problem because the flip side is also true: if you launch a program and don't do anything with it, other programs will be able to use memory that the first program originally wanted to reserve. It is all very fluid and complicated and the best thing to do is to do what you want and let OS X do what it wants.
The advantage to closing windows and programs is not so much for memory management but to boost performance a little. The less the machine has to keep track of and redraw and manage, the faster it can do whatever you're trying to concentrate on.
To me it boils down to this: If you're going to use an app again soon, leave it open (I leave Mail and Safari open all the time). If you're not going to use an app soon, close it. All the rest you can leave up to the sophisticated workings of OS X memory management, which are really not worth second guessing unless you are a very smart engineer.
