PLEASE HELP!! (May need super advanced mac experts)
One line sums it up: my MacBook won't start up.
It starts, because there's the "start up tone", or chime, whatever it's called. But after that, there's just this white screen (in the middle of which an Apple logo will appear under normal circumstances) and some noisy beeping. There's a pattern to the beeping: first one is 2 beeps, and then 3 beeps in every 2 or 3 seconds. Plus, when it beeps, the sleep light follows the pattern.
You may think I can boot from the Mac OS Installation Disc, or do a hardware test, or anything like that. I'm sorry, but I can't. I tried, but I can't.
But somehow, just this one time, I got into Target Disk Mode, using my old Powerbook as the host. Backed up everything to an external HD, and then I thought I could erase the HD on my MacBook, and everything would be fine. But the problem is still the same.
Now I can't boot from anything, can't perform hardware test (which I believe is pretty pointless anyway), can't boot in Safe Mode, etc etc. I can't even eject the Mac OS Installation disc because none of keys (including the eject key) have any effect during startup now.
Please help!!!
PS My MacBook is running on 10.5.3, but I think that's irrelevant now, because the HD is blank the moment.
If you cannot startup from the installation disc without the same problem occurring, then it would appear you have a serious hardware problem. The beeping suggests a possible problem with RAM, but generally the normal startup chime is replaced by the beeping. However, you may still have a RAM related problem.
In any event you will need to take the computer in for service. We cannot fix hardware.

A little help writing an SQL please? May need some advanced functionality..
Hi All
I have arequirement to write an SQL that, given a total, and some rows from a table, can return the rows where one of the columns adds up to the total
These are transactions, so I'll boil it down to:
TranID, TranAmount
1, 100
2, 200
3, 250
4, 50
Suppose I will know that I need to seek 2 transactions totalling 300.
Possible combinations are ID 1+2, or 3+4. In this case, it is an error that I cannot find a single set of transactions that satisfies the number-of and the sum-of requirements
Suppose I will know that I need to seek 3 transactions totalling 550.
Only combination is ID 1+2+3
The difficulty for me here comes in that the number of transactions hunted will change, possibly without limits but as there will be a factorial element in terms of number of combinations, imposing an upper limit would be sensible.
I considered one solution within my understanding of SQL, that I can take my rows, and (supposing I enforce a limit of 3.. i.e. I cannot look for any more than a combination of 3 transactions) cross join them to themselves on condition that no tran ID is equal to any other tran ID, I will then get a huge block of cartesian joined transactions. I can then use a where clause to pick out row combinations having the correct sum. If I can use some kind of ID > otherID in my join, then I can make the cartesian a triangle shape which hopefully would prevent essentially duplicated rows of 1,2,3 and 1,3,2 and 3,2,1 and 3,1,2 etc
If I was only looking for 2 or 1 possible combinations, I would replace the tran amounts with 0 using a case when (because the number of times I'll cross join is fixed; I dont want to get into executing a dynamic sql)
Lastly I should point out that I'm doing this in PL/SQL or possibly Java so I have the ability to introduce custom logic if needs be
I would love to hear any other input from the wise and wizened members here as to how they might approach this problem.. Maybe oracle has some cool analytical functionality that I do not know of that will help here?
Thanks in advance guys n girls!>
Now, as I'll be looking to update another columns on these transactions so that it can be picked up by an external process, can I modify this query so that it produces a list of TranIDs so I can say:
UPDATE tran SET falg='Y' WHERE tranID IN (<the query>)
>
Well if there's a workaround for the NOCYCLE, then the following will give all the transactions as rows for a particular total...

I've installed windows 7 with the help of bootcamp on my macbook pro 2011.
Please help me how to install mac drivers for windows7 64 bit???You either download drivers from within Boot Camp Assistant and save to USB FAT disk, or you insert and use 10.6.x OS X DVD when in Windows and install and run the SETUP from there.

Macs that work with 64-bit editions of Microsoft Windows Vista and Windows 7
http://support.apple.com/kb/HT1846
Step 4: Install the Boot Camp Drivers for Windows
After installing Windows, install Mac-specific drivers and other software for Windows using your Mac OS X installation disc. The Mac OS X disc installs drivers to support Mac components, including AirPort,built-in iSight camera, the Apple Remote, the trackpad on a portable Mac, and thefunction keys on an Apple keyboard.
The Mac OS X disc also installs the Boot Camp control panel for Windows and theApple Boot Camp system tray item.
To install the Boot Camp drivers:
1 Eject the Windows installation disc.
2 Insert the Mac OS X disc. If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
3 Follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
Windows that appear only briefly during the installation don’t require your input.
If nothing appears to be happening, there may be a hidden window that you mustrespond to. Check the taskbar and look behind open windows.
Important: Do not click the Cancel button in any of the installer dialogs.
4 After your computer restarts, follow the instructions in the Found New Hardware Wizard to update your software drivers (Windows XP only).
5 Follow the instructions for any other wizards that appear.
6 Check for updated Boot Camp drivers by using Apple Software Update or going to www.apple.com/support/bootcamp.
If You Have Problems Installing the Device Drivers
If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
To repair Boot Camp drivers:
1 Start up your computer in Windows.
2 Insert your Mac OS X installation disc.
3 If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
4 Click Repair and follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
If you need to reinstall specific drivers, you can install one driver at a time. For example,if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
Individual drivers are in the Drivers folder on the Mac OS X installation disc. -

icalentor and ilife keep asking me about the keychain password ,wich i don't event know about (login password dosn't work), if any one knows about this ,and how to avoid from that ? thank you ! please help ,.i am a new mac user .
See if this helps...
Open Keychain Access in Utilities, use Keychain First Aid under the Keychain Menu item, then either check the Password under that item, change it, or delete it and start over.
Keychain Access asks for keychain "login" after changing login password...

If Keychain First Aid finds an issue that it cannot repair, or if you do not know your keychain password, you may need to reset your keychain.

HT3606 please help me to upgrade my mac osx 10.5.8 to mountain lion
please help me to upgrade my mac osx 10.5.8 to mountain lion. i am not able to do it.becoz i am not having app store.
Before you buy anything, first make sure your Mac is compatible.
Minimum specs for Snow Leopard. Mac OS X v10.6 Snow Leopard - Read the Technical Specifications
Note. You can no longer buy Snow Leopard from an Apple retail store, only as follows.
If you are in North America ... Last I read, you must call them (1-800-MY-APPLE). It is $29 plus tax for family pack and $19 plus tax for the individual use version.
In Europe or otherwise … call your National Apple Helpline … http://support.apple.com/kb/HE57
Once you have bought and upgraded you will need to apply the Combo updater for Snow Leopard. Mac OS X 10.6.8 Update Combo v1.1
For Mountain Lion the minimum specs are … technical specifications.
But if your computer meets those specs you can upgrade to Mountain Lion without any intermediate steps. -

Welcome to the discussion area!
When the Time Capsule disk starts to become full, Time Machine will automatically delete the oldest backups first to make room for new backups.
For more details, I think you will get a faster and more informed response if you post in the TIme Machine forum for questions like this. We primarily handle configuration set up and networking questons about the Time Capsule as a hardware device on this forum, but it's possible that someone may see your post and respond from here as well.
