Why does the macbook pro use both types of storage?

Why does the 13inch retina have both the 8gb hardrive and the flashdrive?

Oops reading your question again, I see there is a misunderstanding:
http://www.apple.com/macbook-pro/specs-retina/
The 8GB is not hard drive memory. It is chip memory just for multi-tasking purposes, and it can be custom configured to 16 GB of multi-tasking memory. If you wanted to store applications or data files on it, you can create a RAM disk, but it actually would be copying the information off the SSD. There is no "permanent" storage of data on the 8GB or 16GB of RAM.
There is no platter hard drive anymore.
The 128 GB is the SSD memory on the 13" model by default, and can be custom configured to 512GB of SSD memory.
The odd thing is your SSD can do swap file storage for multitasking, but also doubles as your place to store actual data files.
For awhile Apple mixed both platter and SSD. Looks like that is no longer the case at least with the 13" Retina.
SSD memory is comparable to hard drive memory in that it is more "permanent" storage after reboot. Calling it permanent is a misnomer though, since hard drives and SSDs can both fail without any warning, and a backup is always recommended:

Why does the MacBook Pro make a loud heat noise?

So, when I was playing a game called "Modern Combat Domination" my MacBook Pro make a very loud heat noise? Does that mean I should stop playing the game? I worried. Thank You.

That means your fan(s) sped up to dispose of the excess heat generated by playing the game. It's a sign that your machine is taking care of itself properly.

Why does my Macbook Pro use so much power in sleep?

Hi everyone, forum newbie here
My mid 2010 Macbook Pro (13.3" C2D 2.66ghz, 4GB etc) uses a lot of energy during sleep
It drains between 2-5% per hour, which believe me is a lot. My battery lasts anything from 3-4 hours to 8 ish if I'm using it very little, so to deplete roughly 5% per hour is not that much less than the laptop uses when it's switched on... so what's going on here?
I'm sure it's asleep all the time, not waking up for whatever reason, the blinking/breathing LED on the front side of the laptop glows and dims so I know it's in sleep mode.
Can anyone help me? Thankyou!

Your situation is not unique. Another long thread https://discussions.apple.com/thread/1758587?start=90&tstart=0 suggests that a solution is not yet forthcoming.
You can, however, partially remedy the situation by (1) making sure your system is not too warm or hot - this really reduces the life of your battery; (2) Keep your unit charged for portions of the day; display quality is better while powered, and battery will keep more of its power; (3) In some cases, keeping your MBP connected to USB cables can leech power from your system; detach all cables before sleeping.
Of course, this won't solve the problem, but it will improve things. If it's any consolation, many (but not all) Windowz units report the same problem.
Post here if you have any comments, advice, or even feedback!

Why does the macbook pro restart in few seconds after I select "shut down?"

When I select shut down, the computer goes off and comes on again in a few seconds. It doesn't come on quickly like it does when I select restart. It's like a ghost is in there.

Unplug all the USB devices you don't need or put a hub with its own power supply between the computer and them.

Why does my macbook pro stop loading the webpage every time i try to access netflix or youtube?

Why does my macbook pro stop loading the webpage (in safari) every time I try to access netflix or youtube?

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Why does my macbook pro retina display shutdown while entering the administer account

why does my macbook pro retina display shutdown while entering the administer account

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does my MacBook Pro and Mac Pro keep freezing?

Why does my MacBook Pro freeze?
MacBook Pro
2.4 GHz intel Core2 Duo
4BB 1067 MHz DDR3
OSX 10.6.8 Snow Leopard
I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
Tried safe boot several times. No help.
Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
Couldn't clear cache etc as couldn't get to the relevant part to do it.
Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said “The volume appears to be OK”. No help.
Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
Cheers

... does Apple products work much better with using Apple routers?
While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.

Why does my Macbook Pro destabilize after hibernation sleep?

Over the last several months using Mountain Lion, I decided to completely drain my battery to reset it. I think it then goes into what is called hibernation or emergency sleep mode. I am usually unable to wake it from sleep prompting a forced resstart.
to restart, I connect the adapter and the light goes green quickly changing to amber as expected. After the restart, however, some top menu items are missing such as the wi-fi icon and the Lock Keychain icon. All third party icons display correctkly. The space is there but blank and I can access the pulldown menu by clicking in those blank areas.. When double clicking the HD icon in the Finder, no icons show on the left side any more. A restart does not fix the problem. The system then eventually destabilizes to the point that I have to restore from my Firewire external HD clone using SuperDuper. One time I did a full restore (that takes forever even with a very fast wi-fi set up) to fix the problem.
I am usually in Safari or playing a Game such as a third party card game application to pass the time until the battery completely drains. I also have Filevault enabled.
Why is the MacBook Pro battery reset causing this OS instability? How can I reset the battery without encountering these sleep issues?

Thank you Dale.
This article mentions that recalibration should be done every two months. I think I waited 4-6 months before doing a recalibration on purpose. Though I probably ran out the battery power before then recharging overnight (some commenters on Apple Discussions said to wait 5 hours before recharging!).
I think that my battery goes into a forced shutdown rather than true sleep. Your linked thread states that this often causes directory damage. But I ran DiskWarrior and Disk Utility immediately after the stated problems occurred. And these programs pretty much repair any directory damage. But they failed to correct the problems I listed in my original post.
So I question the conclusion that not calibrating every two months caused irreparable directory damage that even DiskWarrior or Disk Utility cannot repair. The damage appears more extensive than this in my opinion.
The battery is only a year old with 92.35% of its original current capacity and 537 cycles. The current charge is over 6350 at 99.47%. It will eventually go to 100%. I can run over 4 hours of normal usage on a single battery charge.
Side note -- to my knowledge, nothing in the original MacBook Pro manual suggests that the battery requires regular recalibration of any kind to maintain the integrity of the battery. Much less every two months. If this is a requirement or even highly recommended, then Apple has done a good job hiding this information. And the available recalibration information varies from one type of battery to the next and is often inconsistent.
Apple's comments in the past support the idea that recalibration improves efficiency and fixes some battery issues as they occur, but that it is not manditory to maintain the health of the battery.
Do you have an official battery recalibration source (preferably Apple) that indicates regular battery recalibration is crucial and exactly how this must be done for MacBooks with builtin batteries?

Why does my macbook pro get hot

Why does my Macbook pro get hot while I am only on my email account? This is a recent change. It gets too hot too put in my lap. Is it a battery issue.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Why does the MacBook Retina 15" do software scaling to the native resolution of 2880x1800?

OS X does not allow changing the viewport resolution to the native 2880x1800, and it suggests 1440x900 as a retina optimized one. This means that software scaling is done on the fly. My question is, why?
I have two suspicions:
1. Running everything at the native resolution puts a bigger strain on the GPU, hence slowing down the OS, putting down battery time.
2. The number of apps using retina-ready sprites is miniscule, hence Apple does not want to mess with the user experience. Although I doubt it, as software post-processing is done even now, and apps with non-retina sprites look slightly blurred. If the native resolution would have been used, they would just look a bit more blurry.
Just some comments:
1. Switching to the native resolution will make everything smaller, up to the point of not being usable. But this is a non-argument, as the OS could be smart enough to use bigger versions of the sprites/icons/text. Apple already demands that developers use hi-res sprites (OS X Human Interface Guidelines), hence everything could be scaled x2 and it would be the same size at 2880x1800, as it is at 1440x900 in the current version of the OS.
2. Technically it is possible, as outlined here: Running the Retina MacBook Pro at Full 2880x1800 Resolution. Have a look at the comments too, there are some interesting observations in line with this question, but no definite answers.
3. I am aware that the OS X Cocoa server is running at native resolution at all times. This question is concerned with the viewport resolution, which requires hacks to be set to the native one.

Why is the MacBook Pro Serial ATA transfer speed half that of the new iMac?

I have a MacBook Pro 2.4 GHz 15.4 inch with a Seagate Momentus 160 GB, 7200 rpm, serial ATA, PRT hard drive. This hard drive has a serial ATA transfer speed rating of 3.0 Gigabits per second. The MBP logic board has an Intel 965 chip set that has a serial transfer speed rating of 3.0 Gigabits per second. I was at the Mac Store the other day and noticed that the new iMac 20 and 24 inch computers (that have the same intel 965 chip set) have an Intel ICH8-MAHCI speed rating of 3.0 Gigabits per second. My question is why does the MacBook and MacBook Pro's only have an Intel ICH8-M AHCI speed rating of 1.5 Gigabits per second? Attached is a copy of my Serial-ATA information:

For several reason although the main one is that the vast majority of 2.5" drives have a 1.5Gbps interfacce. Drives with a 3Gbps interface in this size are rare where as they're very common in the 3.5" drive size which is used in the iMac.
Additionally you'll find that few drives do in fact make use of this larger bandwidth. For instance, the fastest 3.5" SATA drive one can buy for an iMac/Mac Pro up to 500GB is in fact a Western Digital Raptor 150GB which has an SATA I 1.5Gbps interface. So the interface bandwidth isn't everything. Yes there are faster drives than this now but they are in the 750GB size and up.
