Can't re-install OSX

When I purcahsed this Macbook it was running Snow Leopard then upgraded to Lion and now Mavericks.
Lately I am having problem updating Apps from Itunes, it shows a different Apple ID and I can't change it.
I have tried all and various ways to solve that problem but to no avail. So I decided to re-install OSX using the original DVD provided.
It shows you can't run this version. So I tried using the Disk Utilities but prompted Apple ID and Password.
Frustrastingly, it mentioned this wasn't the password during the purchase of the Maverick. I have all ways but gave up.
Please assist, thanks.

You may need to invest in DiskWarrior. It can sometimes see and repair a hard drive that cannot be seen by Apple's own Disk Utility.

Can't re-install osx lion / osx mavericks

Hey guys I have a MBP 13" Late 2011.
My problem is that just recently, I was not able to boot into osx mavericks. (Originally had Lion, but I upgraded)
It kept getting stuck at the apple boot logo. I had windows 7 installed on my macbook through bootcamp and I'm able to boot there just fine.
I ended up having to erase my osx mavericks hdd. I was planning on reinstalling mavericks, but I wasn't able to because it said I needed to have osx lion installed. I don't have the install disk, if there is one, because it was pre-installed when the laptop was bought. I also don't have the original apple id that was used to purchase osx lion.
Is there some other way to re-install osx mavericks?
Thanks

That's the problem. Mavericks has to be downloaded with your user ID in order for it to install. What model is your system?

Can't re-install OSX 10.1 on iBook G3 700 MHz

Hey,
When I try and install the OS either by software restore or the OSX disc itself, it can't find the HD. A previous install attempt went sour and now I think I'm paying the price. I think the HD is okay physically.
I have a powerbook and external FW HDs if this might help.
thanks,
Crazy

Hi
If you do have a firewire hd, try it out. Just hold option as you boot to choose it, if you can start up off it, you can see if your hard drive works. Do you gave tectool? It comes with the applecare cd. It can tell you if anything is wrong with the hd. Or, an apple store will test it for you. You might need a new hd, though, as it is strange it wouldent be recognised.
Hope this helps
ps...if you have a firewire cable, you can boot off the powerbook, just hold f as you boot. Your hd should appear.

Can custom build install OSX?

Hi, I just wondering about this since I want to spend my own money to buy custom build so I want to install Microsoft Windows 7 and Apple MAC OSX so I hope you guys can help me to decide what is the best to get it.
P.S. I rather to have custom than buy iMac or Macbook Pro (just because they dont have blu ray)
Thanks,

What type of programs are you intending on running? If you only need to run Office, Email, and Web applications then 4GB of RAM should be enough, but if you plan on doing any creative professional work, virtualization, or scientific computing then 8GB of RAM or more would be preferred.
As for Windows, Apple provides Boot Camp, which will allow you to install Windows to a second partition on your hard drive (dual-booting). However, this requires you to shut down the Mac side in order to run Windows, and vice versa. An alternative to this is to use a virtalization program like Parallels Desktop or VMWare Fusion, which will allow you to run Windows within OS X. The benefit is you can run programs side-by-side with your Mac programs, but at a cost of overall performance (and dong such will use more system resources and thereby require more RAM, so 8GB would be a minimum I would recommend).
The only options for building a supported Mac system are through Apple's online store, where you will configure a Mac system for your needs by choosing items like CPU speeds, RAM, and hard drive options. Apple does not support Blu Ray on its systems.

Why can't I install OSX 10.7 on my 20" imac?

I want to be able to run iTunes radio on my late 2006 20" iMac but it requires OSX 10.7. I have OSX 10.6.8 and I don't know why I cannot install 10.7 on this model iMac.

I did not try to download or purchase Lion because of other posts that I read. Perhaps I misread, but I was just trying to understand the technical reason for he limitation (memory, cpu, etc) and also see if somebody had an alternative to get iTunes Radio. I did upgrade the memory to 4 gigs but have the "late 2006 iMac".
Thanks

Can't re install OSX Yosemite

Hi,
I have multiple problems on a 13" macbook Pro. (late 2009) which has no backup..
1. Computer shuts down after about 1 third of booting.
2. Unable to boot in safe mode.
3. Unable to re install Yosemite because disk is locked.
Would anyone have any idea on how to unlock the disk so I could re-install Yosemite without having to wipe the disk first ?
Thank you for your help guys !

Disk can be locked for many reasons. In your case, the most possible case is that you have a software (or Hardware) corruption on your Hard Drive. Boot your Macbook Pro to Recovery mode: OS X: About OS X Recovery - Apple Support
From OS X Utility Window select Disk Utility, and when this tool is fully loaded, select your OS partition (by default called Macintosh HD) and Verify Disk first and if necessary Repair Disk if possible:
Using Disk Utility to verify or repair disks - Apple Support
Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support
If Disk Utility cannot repair your disk, then you will need to Erase your drive and reinstall OS X (this will also wipe all of your data): OS X Yosemite: Erase and reinstall OS X
If you do not have a backup of your files then you have a few options that you could try to attempt to rescue your data but this will require additional devices and your patience...
You could try Target Disk Modet: OS X Mountain Lion: Transfer files between two computers using target disk mode
If you don't have an access to other Mac, but you do have an access to empty USB External Hard Drive, then by booting your Mac to Recovery Mode, you can install OS X on External Hard Drive (use external Hard Drive partition as a destination disk for OS X) and that will give you an option to access files on corrupted drive to copy them before erasing your Internal Drive and Installing OS X again.

Can I remote install OSX 10.6?

I am looking at purchasing a used Macbook Pro 1,1 for $400. It's an intel Core Duo 2GHZ with 1GB RAM. The CD Drive is broken (there is a small dent on the side and the seller says he dropped the MBP and from that dent forward the drive no longer functioned). Overall the computer is in good shape besides this dent.
My question is a two parter: I have a MBP myself and an iMac. Can I somehow remote install Snow Leopard (and Lion when it comes out) with the install disc?
And two: is $400 worth this?
Thanks!

Yes it's possible to get OS X onto a Mac without a Superdrive.
What you need to do is get a powered external drive and another Mac that's the same make and model, use it to Disk Utility format HFS+ Journaled the external drive.
You can use the Snow Leopard retail disks and another different Mac possibly, no free iLife (that only comes on the disks with the comptuer).
Then c boot off the installer disks that come with the Mac (either one will do) install OS X onto the external drive and reboot holding option. You select the external drive to boot from.
Then you setup the accounts, and software update fully, download the free/donationware Carbon Copy Cloner to this external OS X drive.
Now take this external drive to the broken Mac and reboot holding option, if everything works then your good to go ahead and clone that external drive to the internal drive of the broken Mac and set it as the startup disk in system prefs.
There is also a way to install OS X onto a Flash thumb drive however I haven't researched it.
Also OS X Lion is downloaded and installed via the MacAppStore, no disks. So you won't have to worry about that, but you need to update CCC for Lion so it will clone it. Lion will have a recovery partition on the drive, so it's even easier to repair.
Lion won't run on the following Intel based machines.
iMac 4,1 Early (Jan-Sept) 2006 17"
iMac 4,1 Early (Jan-Sept) 2006 20"
iMac 4,2 Mid (July-Sept) 2006 17"

How to use FireWire target disk mode
Learn what FireWire target disk mode (TDM) is and how to use it.
Description and requirements
FireWire target disk mode allows a Macintosh computer with a FireWire port (the target computer) to be used as an external hard disk connected to another computer (the host). Once a target computer is started up as a FireWire hard disk and is available to the host computer, you can copy files to or from that volume.
Important: The computer will not go into FireWire target disk mode if "Open Firmware Password" has been enabled.
Host computer requirements
Host computers must meet the following requirements:
* Built-in FireWire port, or a FireWire port on a PC card
* FireWire 2.3.3 or later
* Mac OS 8.6 or later
Target computers
The following models can be used as target computers:
* iMac (Slot Loading) with Firmware version 2.4 or later
* iMac (Summer 2000) and all models introduced after July 2000
* eMac (all models)
* Mac mini (all models)
* Power Mac G4 (AGP Graphics) with ATA drive
* Power Mac G4 Cube
* Power Mac G4 (Gigabit Ethernet) and all models introduced after July 2000
* Power Mac G5 (all models)
* iBook (FireWire) and all models introduced after September 2000
* MacBook (all models)
* PowerBook G3 (FireWire)
* PowerBook G4 (all models)
* MacBook Pro (all models)
FireWire software
You can download the latest Firmware and FireWire software from the Apple Support Downloads page (http://www.apple.com/support/downloads/).
How to use FireWire target disk mode
Important: Unplug all other FireWire devices from both computers prior to using FireWire target disk mode. Do not plug in any FireWire devices until after you have disconnected the two computers from each other, or have stopped using target disk mode.
Tip: If you will be transferring FileVault-protected home directories (Mac OS X 10.3 or later only), log in as the FileVault-protected user and temporarily turn off FileVault. After transferring home directory contents to the target computer, enable FileVault protection again if desired.
To use FireWire target disk mode
1. Make sure that the target computer is turned off. If you are using a PowerBook or iBook as the target computer, you should also plug in its AC power adapter.
2. Use a FireWire cable (6-pin to 6-pin) to connect the target computer to a host computer. The host computer does not need to be turned off.
3. Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop. (If the target computer is running Mac OS X 10.4 Tiger, you can also open System Preferences, choose Startup Disk, and click Target Disk Mode. Then restart the computer and it will start up in Target Disk Mode.)
4. When you are finished copying files, drag the target computer's hard disk icon to the Trash or select Put Away from the File menu (Mac OS 9) or Eject from the File menu (Mac OS X).
5. Press the target computer's power button to turn it off.
6. Unplug the FireWire cable.
If the target computer's hard disk does not become available to the host computer, check the cable connections and restart the host computer.
Find out about "FireWire Ports and Specifications".
Tip: FireWire Target Disk Mode works on internal ATA drives only. Target Disk Mode only connects to the master ATA drive on the Ultra ATA bus. It will not connect to Slave ATA, ATAPI or SCSI drives.
Using Target Disk Mode with Intel-based Macs
If you attempt to mount an Intel-based Mac in Target Disk Mode on a Macintosh running Mac OS X 10.3.9 or earlier, you'll see an alert message. For more information, see article 303118, "Intel-based Macs: "You have inserted a disk containing no volumes that Mac OS X can read" alert message".

Remote printer is recognized but message says can't find printer? It worked great before installing OSX Maverick

Remote printer is recognized but message says can't find printer? It worked great before installing OSX Maverick?

Thank you for your response.
Unfortunately I have already rebooted the router and that did not fix the problem. The weird thing is that the computer is connected to the network, it just won't connect to my computer. I have printed the network configuration page to confirm this, and it says the wireless signal is strong.
I have not changed anything at all recently in terms of routers, networks, etc. The printer stopped working completely randomly.
Is there a part in the printer that like emits a signal which computers, phones, etc are supposed to detect? I don't know enough about the mechanics to really theorize about what is wrong, but it seems like that is the only thing that stopped working.
Do you have any other suggestions?

You installed a hacked app, originally from the Mac App Store. It contains the receipt for a different app, downloaded using an account that you don't control. You need to identify and remove the hacked app.
Important: The app you need to remove is not necessarily the one named in the App Store alert. For example, the App Store may prompt you to update "Angry Birds" or "Twitter," but the hacked app may be something else entirely. Don't make any assumptions about which app you're looking for. To find it, you must carry out a systematic search with Spotlight.
1. Triple-click anywhere in the line of text below on this page to select it:
kMDItemAppStoreHasReceipt=1
Copy the selected text to the Clipboard by pressing the key combination command-C.
2. In the Finder, press command-F to open a search window, or select
File ▹ Find
from the menu bar. In the search window, select
Search: This Mac
from the row of tokens below the toolbar. Below that is a popup menu of search criteria, initially showing Kind. From that menu, select
Other...
A sheet will drop down. In that sheet, select
Raw Query
as the criterion, then click OK or press return.
Now there will be a text box to the right of the menu of search criteria. That's where you enter the raw search query. Click in that box and paste the text you copied earlier by pressing command-V.
4. The search window will now show all the App Store products that are installed. Compare those search results with the list of your purchases from the App Store. To see the complete list, you may need to unhide hidden purchases. If any apps were download from the App Store using other Apple ID accounts that you control, sign in to the store under each of those ID's and check the purchases.
At least one of the apps in the Spotlight search results is not among your purchases in the App Store. Move each such item to the Trash, after quitting it if it's running. You may be prompted for your administrator password. Empty the Trash.
Quit and relaunch the App Store. Test.
If you find these instructions confusing, ask for an alternative method.

My daughter has a 2002 intel running Tiger and I want to update it to Snow Leopard. I get an error message that OSX can't be installed on this system. Please help!!! Thanks

Hi,
I'm having a really hard time here.
I want to update my daughters intel from Tiger to Snow Leopard for her to make her life (and mine) easier.
When I try install the OS, I keep getting an error message that OSX can't be installed on this Mac.
What's going on?
Never had so much trouble before.
Please help.
Thanks so much

You're welcome. Please note that it is a little more difficult to obtain Snow Leopard these days. Please see the post by Kappy at the link below.

Can't install OSX on firewire drive?!?

I have a brand new Mac Mini (specs below) and just purchased an OWC Ministack v2 for extra USB and Firewire ports, with a Hitachi 250GB drive in it.
It's in 1394 mode, hooked up to the Mini, which recognizes it as a firewire drive. I'm able to copy files to it and open them fine, drive passes all tests.
When I insert the Install Disc 1 that came with the Mac Mini, I run the installer, which boots up from the disc and askes for the destination. It sees the firewire drive, but says that I cannot install OSX on that volume.
My question is, does the installer only allow you to install OSX on the Mini drive itself?!? Or is there something wrong with my drive? Anything I can do to get around this?
I have a separate Tiger install CD, but the Mini can't run the installer (presumably because it's pre-Universal Binary?).
THANKS a ton for your feedback, much appreciated.

Aye that was certainly the reason behind the problems I recently had when I was setting up an external drive with my Intel MacBook Pro.
After much testing and a little searching via Google, it would seem that Disk Utility was formatting the drive as an Apple Partition Map (APM) partition rather than a GUID Partition Table (GPT) that is necessary to use an external drive as a startup drive for an Intel Mac.

Replaced hard drive can't install OSX

A friend gave me an iBook G3 500 MgHz. I want it to coordinate with my iMac G5 to be able to use same Tiger software. I put in 640 MB of Ram, then installed OSX 10.4. Everything OK but the modem was broke and there was not much room on HD. So I bought new 80Gig Toshiba HD and new modem, did the surgery using excellent iFixit instructions and went to reinstall OSX from my cds. The computer works if I start it with OSX installer cd, and the disk utility and System Profiler show the hard drive properly,
BUT WHEN I START THE INSTALLER THE HARD DRIVE DOESN'T SHOW UP AS THE DESTINATION DRIVE,NOTHING SHOWS UP AS A POSSIBLE DESTINATION DRIVE.
DID I MISS A MAJOR STEP TO PREPARE THE COMPUTER FOR A NEW HD? IS THERE SOMETHING I CAN DO WITH DISK UTILITY TO MAKE IT SHOW UP?
HELP

Hi, and welcome to Apple Discussions.
In a Mac, it's called Open Firmware, and you get there by holding down the Command (Apple) Key + Option + o + f.
If it's a G4 (and it sounds like it is because the G3's have tray-loading optical drives), you may want to try posting in the iBook G4 Forum.
You have posted in the iBook G3 (Dual USB) Forum.
Also, an iBook G4 will not have version OS X 10.1.x (that version of the operating system is too old for an iBook G4), so you may want to check that information.
