I need information on my machine.

I'm thinking about getting a new laptop, I cannot remember if the macbook i have now is dual core or quad core, and it would be helpful to know as reference. Its a mid 2012 13 inch non retina, 2.9ghz, i7, how do i found out about the cores? Thanks

Try 'Apple Menu > About this Mac'.
See if that lists the cores.
You can click the more info to get a bit more detail and then click the 'system report' for lots of detail.

Could Not Find Installation Information for this Machine" I need Help!

i accidentaly erased the main drive and now i am trying hard to reinstal the OS X again but i constantly keep seeing this "could not find installation information for this machine" i need help....

hello,
I had the same problem yesterday, just go to a place with a better internet conncetion, it will work fine...
good luck

Could not find installation information for this machine contact applecare

I installed Lion on my MacBook, worked great. After 2 months I wanted to clean install the Lion on the same Macbook; went to Apple Support website and there they had instructions on how to clean install Lion.
I followed the instructions and erased the partition where the OS Lion was installed. Then I tried to re-install it, it kept saying "could not find installation information for this machine contact applecare".
When I contacted apple care, they asked me to pay 49 dollars in order to get help from them. I already paid the cost for the LION OS and now they want another 49 bucks. This is just insane. I'm not a fan of Apple, Mac or iCrap. But I was thinking to buy a new Mac after selling this one. Now I have no interest in buying any Mac product. Windows 7 is much much better than Lion OS X.
I have to fix this before I sell it on ebay so Has anyone tried to clean install Lion ?

I'm with you, OS X Lion has turned a lot of stomachs.
Here's how to go about what you need to do:
Get out your 10.6 installer disk, make sure it's clean and polished (bit of rubbing alcohol and a very soft cloth)
Get 2 blank external drives, connect one and hold c and boot off the 10.6 installer disk, use Disk Utility to format the external drive use
Erase>Security Option> Zero all data, wait
under the partition tab
1 partition, option MBR, format FAT
Disconnect and reboot.
Repeat the same procedure for the second drive and format the
Erase>Security Option> Zero all data, wait
under the partition tab
1 partition, option GUID, format OS X Extended Journaled
Quit and install 10.6 on the external GUID drive.
Reboot holding the option key, you can boot off the 10.6 external drive, setup, use your same user name as before, update to 10.6.8, grab your files off the OSX Lion partition, transfer a copy to the FAT formatted drive.
What you do is your choice,
To continue using the machine under 10.6
you can erase the entire (select the whole internal drive, not just the OS X Lion Paritition) and use Carbon Copy Cloner to clone 10.6 external to the internal drive,
To sell the machine with a fresh 10.6 install
or simply hold c boot off the 10.6 installer disk and install 10.6 on the internal drive and upon reboot, just hard shutdown by pressing the powerbutton before going through setup. The next person who gets the machine will be greeted by the setup again.
You can use the files on the FAT drive on your Windows PC in some cases.
Else download the free LibreOffice and it can read quite a few file formats.

If I completely fill my hard drive 500Gb how time machine will keep working having 1Tb of total space, I mean I have to delete mu hard drive but how I keep my previous information on time machine and keep using to with new information?

If I completely fill my hard drive 500Gb how time machine will keep working having 1Tb of total space [externak hard drive], I mean I have to delete my hard drive but how I keep my previous information on time machine and keep using it with new information?

Time Machine does not provide archival storage.
If you delete a file from your disk it will eventually be deleted from your TM backup without any notice to you.
You need a second external disk to use for archival storage.
You also need a third disk for backups of the second disk.

My macpro cant find installation information on this machine. help

i am trying to reinstall the Lion but i constantly receivin this "Cant Find installation information on this machine" i need help here.

You need to provide more information on what you are doing. Otherwise, this is how:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

HT4848 Can't find "installation information for this machine"

I have a brand new Mac Mini that came with Mountain Lion Server pre-installed. After having some difficulty(s) migrating from Snow Leopard I wish to revert to a clean re-install and start over. When I attempt to do this I get "Could not find installation information for this machine."
Any help appreciated.
Urgent !!!
Thanks,
Aunty

How are you trying to do the re-install? Are you using the Recovery HD or Internet Recovery. Information here on how to proceed:
http://support.apple.com/kb/HT4718
If you do an erase and install so that the Mac needs to be setup as if straight out of the box, then Setup Assistant is probably a better way of restoring your data from backup. Details here courtesy of Pondini:

HT1338 could not find intallation information for this machine

i erased my hard drive and was trying to install the new mac ox lion version, but i have this error message:" could find installation information for this machine, contact applecare" i am connected to the internet, i could not find any answer via apple documents and i cant use my mac mini!!! i dont kow what to do, please i need help to intall the mac os or restore my previous version
I need help

First question would be:
did your machine come with Lion or another OS? Did you buy it new or used? And, if it came with an earlier OS, do you have the install disks? Did you buy Lion from the app store?
Any helpful suggestions depend on those answers.

I got this Could not find installation information for this machine. what i should do now? i can not use my mac, i got this Could not find installation information for this machine. what i should do now? i can not use my mac

i erased my mac then i tried to download the os x mavericks, wich i had before ; however, i got this Could not find installation information for this machine.

You should not have erased anything. Maverick uses some of the applications from the older software and now that you have erased part of the Operating System you are going to need the Original Install disc's that came with your machine. Hold down the C key while installing then do all of the Software updates then you can install Maverick.

Reinstall OS x "could not find installation information for this machine"

Singapore ISP Singtel is having issues with Apple Internet Recovery.
There is a need to add proxy access via port 8080.
Since I can't even get into Recovery mode, this info doesn't help.
So, I call up Apple hotline and explain the whole picture.
Was fortunate that Apple has similar feedback from Singapore user.
So, was told to just bring down Mini to service provider.
Problem solved some what.
Service provider only reinstate the ori OS X Lion.
Back home, I download and install ML.
This time, made a copy of ML installer in USB stick for future usage.
I guess the only way around this is getting someone to just install Lion or ML, if Internet recovery doesn't work.

When i tried to reinstall my lion to macbook pro 15'' and connect it to the net it says no installing information for this machine? what's that means??

The internal drive has failed.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

I just purchased Time Capsule today. I ONLY want to use it as an external drive. I do not need it for Time Machine. I can see the TC in my finder, but when I click on a file or video to drag and drop, I get message that TC can't be modified. Help please

I just purchased Time Capsule today. I ONLY want to use it as an external drive. I do not need it for Time Machine. I need to free up room on my computer. As of now, I can't even load updates. I can see the TC in my finder, but when I click on a file or video to drag and drop, I get message that TC can't be modified. Help please!

I agree with Kappy.. passing files and especially via wireless is slow as slow.
Just need to be sure your TC is the new AC model??
And the OS on the computer is Lion?
Have you completed the setup of the TC via the utility? You do still need to get internet via the TC so it has to be plugged into the main router..
Give us the full picture of the network.
Then we can help you get into it.. whether you should put your files on it is another question.

Could not find installation information for this machine

I tried to recover Mac OS X , but got message like this.
"Could not find installation information for this machine. Contact AppleCare."
I can not get detailed information of device because there is no system installed on Mac.
but I remember,It is intel iMac. ver 10.7. core 2 duo.
How do I install or recover system now?

Make sure that your network connection satisfies the requirements for Recovery or Internet Recovery, depending on which you're trying to use. If possible, connect to the router with Ethernet.
Restart the computer and try again.
Connect to a different network, if possible.
Wait a few hours and try again.
Make a "Genius" appointment at an Apple Store.

I get a message of "Could not find installation information for this machine." after trying to Reinstall Mac OS X.

I would like to repartition the Main HD to two Partitions but could not do so and keep on getting an error message of "Could not unmount disc.." so I tried choosing the "Macintosh HD" partition and tried Partitioning it but the option is not available. So to my frustration I tried clicking on "Erase" to see whether doing so would allow me to finally partition my HD but still can't. And now since I erased my Macintosh HD partition I could no longer boot to Lion.
Before doing the above steps I downloaded the Lion Recovery Disc Assistant and created an external Recovery HD using an 8GB flash drive. I used this as startup destination by choosing it as boot destination from pressing Option before startup. I tried using Mac OS X Utilities to Reinstall Mac OS X from the external drive but I only get "Could not find installation information for this machine." message. I also tried booting from the Recovery HD partition on the HD but i also get the same message.
I have a new iMac that came with OS X Lion 10.7.
Anybody have idea how to fix this?

Partitioning on-the-fly may fail if the disk is too fragmented. You cannot run Erase for the internal disk as it contains its system components. The same if trying to run Boot Camp in order to create the Windows partition, it may fail if disk is too fragmented.
If I correctly understand what you want, then you must boot from an external disk, therefore copy Lion to a 4 GB (or higher) flash drive, run the installer, and then choose the option to partition the disk, this is done after rebooting into the installer from the external drive. You cannot do that if the Lion installer is on the internal drive as it cannot erase or repartition itself.
If this fails (did you try this?), then perhaps you can try to create a Lion boot flash or DVD by using a non-Apple app called Lion DiskMaker, when ready restart, after chime press option / alt key, then choose to boot from this newly created boot disk or flash drive. This reportedly works OK (tried with an older version of Lion, not recently, was OK). It is better to work with a flash drive, Lion is not optimized to run from optical media.
WARNING: disregarding the method, you MUST always back up your data when repartitioning or installing / reinstalling.
Hope this helps to solve you issue. Before any attempt, backup, backup, backup.

I need Information about Grid

Hello,
The first, i don't speak english very well.... ;)
the company for which work has 3 seats now, but is going to open 5 more.
All these seats are small, and the cost to install Oracle in each one of them is very elevated.
i would like to know to me if Grid Computing can help me centralizing everything in a Seat. The scalability is something very important. and i need have several instances of BD oracle up...
I need information...
Yo can write me to [email protected]
Thanks in advance

Hi.
By seat, I assume you mean site or location.
It's difficult to answer this type of question as it depends on so many factors. Personally, I would always go for the centralized solution. This way you don't need to worry about replication or distribution of data. Those things are always a nightmare.
RAC is great for high availability, and it will allow you to increase your horsepower as and when you need it, but you still need to consider your performance erquierments up front.
Of course, centralization comes with it's own set of problems. Are you going to connect to the central server via the web, VPN, leased line? What happens when the connection is unavailable?
There is just so much to consider...
Cheers
Tim...
