Hi my MacBook is freezing whenever I try to open an application. I have tried resetting the system management controller, however no success. How can I wipe my hardrive and reinstall it again. PS: I no longer have the installation CDs, can I download it from Apple?

To get replacement installation disks, call Apple. Have the serial number of your MBP ready and a credit card. There is a fee.

i can't charge the bettary if the labpot is turn it on i have to turn it off to can charge it
so is SMC will solve this problem?
and is SMC will not delete my data?

An SMC reset should not delete any data but it's very important to backup your files on a timely basis regardless.
An SMC may help with the battery charging issue.

I have installed the new OS and have lost a part of my personal data: music files and pictures. The new safari is horrible. Give me back the previous version!

These are user-to-user forums, they are not monitored by Apple (there are too many forums/threads/messages for that to happen). If you want to leave feedback for Apple then you can do so here : http://www.apple.com/feedback/ipad.html
What bugs ? Have you not got your music, files, photos on your computer so that you can sync them back to the iPad ?

Reset System Management Controller after changing battery?

I am planning to change my battery. A friend told me that I should reset the power management system, which I assume meant the System Management Controller, in order to reset the battery cycles. Is this correct and how do I do it?

The battery cycle info is contained within the circuitry of the battery. It won' hurt to reset the SMC but it isn't required

My MacBook pro has been running slow lately. It's not much about the internet, I mean slow in loading things like apps and pictures. When I double click an image on my desktop it takes forever to load it up. Help?

I would really like to get it back to how it was when I purchased it, every thing loaded up quickly. My friends have the same model as I and theirs run much faster than mine.

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the system log for messages that may indicate a hardware fault. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|nspace-h|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the 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 (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

NVIDIA nForce System Management Controller: Windows 7 driver?

I have a Fujitsu Siemens PC, Amilo Desktop Pi 3630 A, running Windows Vista Home Premium 32bit,
which I would like to update (preferably without reinstall) to Windows 7.
When I checked Fujitsu's website and also by mail contact, I only got the response
"Your system is not certified for Windows 7"!
So I ran "Microsoft Windows 7 Upgrade Advisor", which said that I can upgrade!
The only issue is that it requires an update to the driver for the
"NVIDIA nForce System Management Controller" [current version is 5.1.2600.158],
but Microsoft directs me to THIS site.
Here I search for a suitable driver for my motherboard, which according the tech spec's is
MB MS-7504PV (or MS-7504VP-PV) with chipset NVIDIA nForce 630i,
but no luck there. The MSI Live Update Online plug-in does not find anything on my Mainboard.
Over at NVIDIA's site I can find a driver for nForce 630i but only paired with GeForce 7xxx,
and I don't think I need a complete motherboard driver package.
Where can I find the correct driver?
Or do I dare try a Windows 7 update anyway?
What can go wrong?
PC: Fujitsu Siemens Amilo Desktop Pi 3630 A
CPU: Intel Core 2 Quad Q8200 2.33GHz
M-board: Fujitsu Siemens / MSI MB MS-7504PV, muATX, v1.1, Socket 775
Chipset: NVIDIA nForce 630i MCP73PV
BIOS: AMI v3.0S
Video: NVIDIA GeForce 9600 GT
LAN: nForce Realtek RTL8211
OS: Windows Vista Home Premium 32bit

You do not have an MSI Retail Product but a mainboard produced exclusively for the OEM Market. Neither MSI nor this forum provides end-user support for OEM products. That is also why MSI Live Update does not find anything for this particular platform (OEM). You need to contact Fujitsu Siemens for assistance (and this include BIOS Updates and drivers).

Howto reset the system number?

I have downloaded the new license key for my new system file but by mistake imported the old one. Now I can't import the new one - get general error. How do I reset the system number? I suspect the license manager tdoes not take it because the the system number differs from the one which is in the file.
thanks

Track down the culprit that resets the system tray customization in Windows 7

The question is duplicated from http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/track-down-the-culprit-that-resets-the-system-tray/7cff4c95-4d08-4a7f-b29d-ce67d8cd6247 as suggested by a support engineer.
Hi Almighty All,
For a while I'm experiencing problems with my system tray. Something regularly resets my customization, i.e. after reboot sometimes all icons that I marked as to show always are hidden again. I found out that the reason is that something erases HCU\Software\Classes\Local
Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify.
I decided to find out what is responsible. I turned on auidt policy for objects, then I setup audit for HCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify. The next time the icons customization was reset I found out
that HCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify was cleared again and on top of that the audit settings were gone! So I thought maybe something just removed the whole key altogether with the audit settings on the
way.
My next attempt was to set audit on HCU\Software\Classes\Local Settings\Software and just let Microsoft\Windows\CurrentVersion\TrayNotify inherit it. The next time the icons customization was reset I found out that HCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify
was cleared again and on top of that the audit settings were gone again! Something removed the whole HCU\Software\Classes\Local Settings\Software?
The Event Log points out to one of the svchost.exe processes, which is just a container for the whole bunch of different services.
Any idea how to find out what service is responsible?
Dei nostra Matrix est.

Hi,
Interesting issue, what about other configuration or settings? Do they work fine or keep reverting after a reboot? Have you tested this issue in another user account? What is the result?
Regarding to unable to save settigs for current user hive, I doubt whether there's an application you installed recently or an malware\virus changes the permission of registry entry or value of registry keys like
HKCU\Software\Classes which causes this issue.
Yolanda Zhu
TechNet Community Support
Hmm... I don't understand. Nothing is reverting after a reboot, as well I'm
not unable to save settings in the current user's hive. The correspondent registry keys can be saved perfectly fine and they are
deleted, not reverted after a reboot. I pointed to the exact code that does it, the code is located in Microsoft DLL with all certificates and digital signatures intact. Permissions obviously don't matter, since svchost.exe is executed with the highest
integrity level and under the System user account, the keys in question inherit permissions, which allow System to do whatever it needs without restrictions
by default, you can't change it to allow more.
So can you explain how it can be some malware?
The issue is intermittent, I don't have a 100% repro, therefore “testing” under another user account is doubtful.

How?

My original Apple ID is associated with an email address that I no longer have access to. How do I reset the system to recognize my new email address as my primary point of contact and erase the other one?

If when you go to icloud.com and sign in with your current iCloud ID you see all your iCloud data there, you can safely sign out of the iCloud account on your Mac and choose Delete at all the prompts, then sign back in with the current ID. This only deletes the data from your Mac, not from iCloud. Your iCloud data will reappear on your Mac when you sign back in after a brief delay as it redownloads. If you have automatically imported your photo stream photos to your iPhoto library you won't lose them either (if you haven't, save them to your library first).
Again, only do this if when you go to icloud.com with your current ID you see your iCloud data there.

HT4759 I have an iMac, iMac, 10,1 10.8. I would like to have iCloud downloaded to my computer. Does my computer have the system requirement necessary. I use iCal on my Apple Notebook and Iphone 4S. Thank you!

I have an iMac, iMac, 10,1 10.8. I would like to have iCloud downloaded to my computer. Does my computer have the system requirement necessary. I use iCal on my Apple Notebook and Iphone 4S and want it to my Mac Desktop to sinc with all my Apple Products. Thank you!

The minimum requirement for iCloud is Lion 10.7.5 (Mavericks preferred): the iCloud Preference Pane does not appear on earlier systems - the MobileMe pane appears on Lion and earlier but is now non-functional - you cannot now open or access a MobileMe account.
To make use of iCloud you will have to upgrade your Mac to Lion or Mavericks, provided it meets the requirements.
The requirements for Lion are:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Lion is available in the Online Apple Store ($19.99). Mountain Lion (10.8.x) is also available there at the same price (though it's reported to have been removed from sale in some countries so may well cease to be available generally) but there seems little point as the system requirements are the same for Mavericks (10.9.x) - which is free - unless you need to run specific software which will run on Mountain Lion only.
The requirements for Mountain Lion and Mavericks are:
OS X v10.6.8 or later
2GB of memory
8GB of available space
and the supported models are:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
Xserve (Early 2009)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
It is available from the Mac App Store (in Applications).
You should be aware that PPC programs (such as AppleWorks) will not run on Lion or above; and some other applications may not be compatible - there is a useful compatibility checklist at http://roaringapps.com/apps:table

[svn] 2700: With the Marshal Plan, when create an instance of a manager, we need to talk to the system manager.

Revision: 2700
Author: [email protected]
Date: 2008-07-31 21:12:03 -0700 (Thu, 31 Jul 2008)
Log Message:
With the Marshal Plan, when create an instance of a manager, we need to talk to the system manager. Unfortunately sometimes these manager instances can be created before the Application class is created and/or before the systemManager property is set on the application. So to get the reference to the system manager from the manager instances, we can't use ApplicationGlobals.application.systemManager. We need to use SystemManagerGlobals.topLevelSystemManagers[0] instead. This property is set in the SystemManager constructor, and fortunately for us, Flash runs your root display object's constructor before anything else, even before static initializers (atleast ones not defined in SystemManager or a dependency of it).

an instance p for Point class is created like this?
Instead we can create and instance of Point class
as:
Point p = new Point();
Can any one of you explain this?Your Point() constructor doesn't throw exceptions, so there's no need to catch them. The Class.forName() and Class.getInstance() methods can throw exceptions, so it's necessary to handle them if they arise. Check out the docs for those methods, it lists what exceptions they can throw.

2) In the above Class Point what is the use of
creating an instance of Point with in that Point
class?
static Point origin = new Point(0,0);
What the reason to create an instance like this
within the same class. We can create this instance of
point
class when ever we need. There doesn't seem to be any in your code, since that variable is never accessed. It could be useful if you wanted to have a Point that was shared across all instances. This is not a good example of that though.
