Installing OSX, Important Question!!!

My HD has gone ga-ga and am waiting to get Disk Warrior to try and fix.
In the mean time would it be possible to install OSX on my 2nd internal drive (currently used for audio and projects) without wiping what is already on it? Am thinking this might be a quick fix to carry on working until I can afford DW.
Could I use Disk Utility to partition the 2nd drive and install OSX on the new partition, as I cannot boot on my main HD?
Many thanks.

Partitioning via Disk Utility is a destructive behavior, as it completely wipes the contents of the hard drive. Several non-destructive third party utilities exist, but some can also have technical issues leaving behind an empty hard drive. My suggestion first is to attempt to recover any information you haven't backed up with Subrosasoft's FileSalvage or Prosoft Data Rescue for your drive that you can't access, as well as backup your data on the accessible hard drive before attempting any repair.
You can install without wiping contents on a data only hard drive, but there is always a risk data might be wiped too. See my FAQ* about backing up:
http://www.macmaps.com/backup.html
As for installing on a disk with no operating system, Mac OS X offers an option called "Install Mac OS X" or "Install Mac OS X for first time." For installing on hard drives with older operating system, you can use "Archive and Install". Note my upgrade FAQ* for other limitations you may run into:

  • Server Specs for a 11.1.1.3 Install Important questions.

    I've put together some specifications for a Development Server & Production Server, any comments appreciated. I hope this post acts as a good reference sample for anybody else out there looking to implement a Hyperion Planning.
    Client Tier: (2 developers)
    Windows
    8 GB RAM
    Dual Core Processor
    Components: EAS client, Smart View, Excel Add-in
    Web Tier:
    HTTP Web and J2EE Servers:
    Windows + (not sure which version would be best here, any ideas appreciated)+
    Processor: 4 x 3 GHZ, 64 bit
    RAM: 8GB
    Hard Drive: 32 GB
    Components: Foundation: HSS, Workspace, Planning, Web Applications: EAS, Financial Reporting, Web Analysis, Planning,
    Services Tier:
    Server1:
    Windows (2003 SP1, R2)
    Processor: 4 x 3 GHZ 64 bit
    RAM: 16 GB

    DISK: 100GB RDBMS
    200GB Essbase Storage
    The specifications will be similar for the production for abotu 25 - 30 users (10 concurrent), with RAM being a little bumped up.
    One important question: I might need guidance on installing 32 bit planning or FDM on the 64 bit server - any known issues with this? Also any known issues with 64 bit Essbase working with 32 bit Planning?
    Edited by: EssbaseApprentice on Sep 30, 2010 10:04 AM

    obviously its hard to comment on whether it is the perfect spec for your environment, it looks alright to me, it is not under spec.
    For the web tier as you are running reporting and analysis and the other machines are windows based personally I would stick with windows 2003.
    Is there any reason why you have one machine dedicated just to FDM, seems a bit of an overkill just for one product, it may be worth combining services server 2 with FDM, just a suggestion though

  • Trying to install OSX.4 sys stalls when booting from dvd

    I've read many of the discussions on this topic. Some are close but none are exactly like the problem I am encountering. I have a Power Mac G4 that was running OS9.2 and I've been trying to install OSX.4. I've tried every possible combination of starting from the dvd but it dones the same thing at the same point everytime. It restarts from the disk, I get the gray screen with the apple logo and the spinning wheel. It will run like this for about a minute or two and then freeze. I can't force quit and I have to restart. I thought it needed a firmware update so I checked the links (I had seen on some of the posts) but it looks like it's a machine that doesn't need one. But I'm not 100% sure how to tell.
    I then went back and started with OSX and OSX.2 and they installed fine. I thought it would have to be installed progressively. But I still have the same issue. I am doing an erase and install with each upgrade. The software is a full retail version for each upgrade as well. Any help would be greatly appreciated.

    Hi Michel,
    Be aware that you can only use an external firewire disk as boot volume since USB is not a bootable interface with MacOS X on PPC-based computers.
    The message you receive is o.k. Insert the Install DVD and reboot while holding down the c-key. This will boot you directly from the CD to the installer application. Once you selected the language, select disk utility from the MENU, select your External drive and format it as "Apple Extended (Journaled)".
    Quit disk utility and proceed with the installation. Make sure you select the external drive as destination!
    When you have to reboot you will boot to the internal disk again. That's o.k. Open disk utility and repair the external disk and also permissions on the external. Next download and install the Mac OS X Update 10.3.9 (Combo). (you are still booted from the internal hard disk, so you will not be prompted for a restart).
    Now restart and hold down the Option-key during boot. In the boot-manager you can select the external disk as boot volume. If your computer booted o.k. you made it! Just remember to Repair permissions before and after an update!
    If this answered your question please consider granting some stars: Why reward points?

    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.

  • How to install OSX 10.7 on a reformatted HD Macbook Pro 13?

    Is there any way of installing OSX 10.7 or 10.8 on a reformatted hard drive of a macbook pro 13 inch late 2009 that originally came with Leopard (OSX 10.5). I have just bought a macbook pro i5 and once all the data was transferred to the newer macbook I reformatted the hard drive of the old MBP in the xpectation that I could simply reinstall Lion. The recovery disc starts up ok, but curiously the installer points to mountain lion only and I keep getting a dialogue box informing me that my apple Id has not previously bought Lion (not Mountainlion, Lion). For starters that is untrue, I bought Lion on the app store to upgrade from Snowleopard to Lion on the original macbook and that shows up in the previous purchases screen in the App store application. Annoyingly this whole process does not allow me to re-purchase Lion on the old macbook pro and I am also now unable to restore the system from Timemachine as this now appears to be associated with the newer machine. And yes, you guessed it, I no longer have the original installation CDs, not realizing that I would still need these after upgrading the operating system (twice).
    Attempts to start up from the only disc that I do have (snowleopard) results in hopeful crunching of the optical drive followed by a grey screen descending across the monitor followed by the message that I must restart the computer and then this process starts again, so getting nowhere and frustration mounting.
    I am now left with a machine that is clinically dead with otherwise perfectly functioning hardware
    I would be most grateful for any advice.
    Thanks

    Purchase the white Snow Leopard 10.6.3 disks Apple sells on their online store.
    Follow these directions, you need to zero erase the ENTIRE drive of the older Mac. (important!)
    How to erase and install Snow Leopard 10.6
    If you don't, the 10.8 RecoveryHD partition will remain and the 10.6 install disk can't repair the 10.8 drive later if there is a issue. There likely also will be a problem installing Lion, as the Recovery HD will be 10.8.
    If you install Lion, it will create it's own Recovery HD for it.
    Once your up, Software Update until 10.6.8, then you can log into AppStore and install Lion if you have already purchased it, or call Apple and special order it, because AppStore goes to 10.8 from 10.6.8 supposedly now.
    You then can reinstall iLife from the 10.5 disks by running the installer or using Paficist from Charlessoft.
    Just to let you know, you cannot sell the machine with 10.7 or 10.8 on it because the next owner needs your AppleID to reinstall or update the OS. 10.7 or 10.8.
    So if your selling it, just install 10.6.3 and press the power button down, it will reboot to the Welcome Video for the next owner.

  • 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.

  • How to install OSX on new SSD?

    I just purchased the 2012 i5 Mac Mini and replaced the 500GB hard drive with a new 128GB Samsung 840 Pro. Built many PCs in the past, but this is my first Mac.
    What are my options for installing OSX on it? When I first boot up I am greeted with a folder with a question mark in it. I hope this is typical? Also, did the SSD need to be formatted first? I just opened it up and put it in. I thought I could just hit command+r to do an internet install, but I have had no luck getting that to work with my Windows keyboard.
    If at all possible, I would prefer not to have to remove the drive again since it's so cumbersome.
    I don't have an external optical drive.
    I do have an external hard drive.
    I do have a few 8GB and 16GB flash drives.
    I have an ethernet cable for internet connection.
    I probably could have done a little more research before doing this, but I would greatly appreciate any help.

    Finally was able to get keyboard to start disk util/internet install. When I started internet install disk was nowhere to be found. I used a SATA to USB cable to boot from the 500GB drive and formatted the SSD. Then rebooted again, and currently finishing internet install. Hope it goes well.

  • Help to do Clean install OSX Mavericks

    I am using osx Mavericks now by upgrading from osx Mountain Lion, I am not feeling better after upgrading, so decided to clean install Mavericks on my Macbook Pro13' 2012 model.Can anyone please assist me to do clean install osx with directions means step by step or picture view.If anyone help me to do this i fell

    The default solution for installing OS X Mavericks is to download it free app store and then perform an upgrade from a previous version of Mac OS X, whether that’s from Mountain Lion or Snow Leopard. Upgrades are fast, efficient, and most important, very easy, and that’s the recommended option for the vast majority of Mac users. Nonetheless, some users may want to start fresh with a blank slate, using what’s known as a “clean install” and that’s what we’re going to cover here. Performing a clean install can be desirable for a variety of reasons, from ditching years of built-up cruft on older Macs from many years of OS X upgrades, to troubleshooting difficult issues, to transferring ownership of a Mac to a new owner.
    The process of a clean install is not difficult if you follow these instructions, but because it involves formatting the Macs hard drive, it can result in extra work. Since the Mac will start with a clean slate, all apps must be downloaded and installed again, important documents and personal data must be manually transferred back over from backups, and system settings must be customized again. This typically makes it more appropriate for advanced users or for select situations (like selling a Mac), and thus it should not be considered a standard upgrade path to get to OS X 10.9 Mavericks.
    Warning: Performing a format and clean install of OS X will erase the Macs hard drive and all contents on the drive will be removed. All files, applications, documents, photos, customizations, everything on the computer will be lost in this process. Understand this and know what you are doing, and why, to prevent data loss of critical files. We can not reiterate this enough.
    How to Format & Clean Install OS X Mavericks on a Mac
    You will need a bootable OS X 10.9 installer drive to accomplish a clean Mavericks install using this method. You can learn how to easily create one here if you haven’t done so yet.
    Back up the Mac first with Time Machine or by manually backing up your important data – do not skip this step or else you will not be able to recover files
    Connect the bootable OS X Mavericks installer drive to the Mac and reboot the computer
    Hold down the OPTION key during boot until you see the boot selector menu, then choose “Install OS X Mavericks”
    At the “OS X Utilities” screen, choose “Disk Utility”
    Select the hard drive or partition to format from the left menu, then choose the “Erase” tab
    Select format type “Mac OS Extended (Journaled)”, give it a logical name (like Macintosh HD), and choose “Erase”, confirm to erase at the next screen
    When finished erasing the disk, quit out of Disk Utility to return to the normal boot menu
    From the “OS X Utilities” menu, now choose “Install OS X”, click “Continue” and agree to the terms of service, and select the freshly formatted “Macintosh HD” drive to begin the clean install process
    (Excuse the unusual picture quality, some images taken with an iPhone 5 during the boot install process where screen shots are not allowed)
    A clean installation of OS X Mavericks takes about 35-45 minutes to complete, depending on the speed of the install drive and the volume OS X is being installed onto. When Mavericks is finished installing, the Mac will reboot itself automatically and go through the initial setup process for OS X Mavericks. Register, create a user login, set the Apple ID and iCloud details, and you’re all done. You’ll boot directly to a very blank OS X installation, similar to the experience of getting a brand new Mac.
    A fresh OS X installation is very bare with just about nothing included outside of the core system and basic Mac apps (intentionally so), thus any custom applications or apps you had previously downloaded from the web or App Store will need to be downloaded and installed again. For apps from the Mac App Store, that’s fairly easy, but for third party apps you will need to access them independently through the developers.
    If you are keeping the Mac yourself, you will probably want to transfer your old data, documents, photos, and files back onto the Mac. This is a good time to access Time Machine to selectively restore certain files, or access backups made to network drives, DropBox, CrashPlan, external backup drives, USB flash disks, whatever your preferred backup method is and from where ever stored your data.

  • Installing OSX onto a G3

    I have made a copy of OSX10.4.8 from my G5 and put it onto my Lacie external hardrive then hooked up the hardrive to my G3 using firewire. Once the lacie mounted on th desktop I was albe to open it up and find the OSX 10 copy, and drag it onto my desktop. Can I now install OSX 10 somehow onto my G3, and if so, what/how do I do this ? And do I have partition the hardive.. on the G3 etc ?

    Hello Again! You may be able to use FTDM to run the installer from the G5. Tom
    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".

  • MEGA180 Important Questions

    I have my MEGA180 on order but I already have some important questions:
    1) This unit provides dual vga outputs. If I install my own AGP 8x card, will the VGA2 output still work? I read in the manual that installing an AGP card will disable VGA1 (default) but it doesn't say anything about the 2nd VGA output connector. I require 2 outputs since I will be connecting to an LCD and my HDTV monitor (using a VGA to Component Video Transcoder)
    2) Will there be performance hits by using the two vga outputs at the same time?
    3) The on-board video card doesn't have any video memory. It will use your existing DDR memory. I will have 512Meg Dual Channel Memory. What kind of performance I can expect from the built-in video card (NVidia NForce Crush18) compared to other AGP cards on the market?
    Thanks for your help!
    Sly

    Though I can not provide you with answers specific to the Mega 180, I can give you some more info.
    1) No. As soon as you install an AGP card, the onboard video will be fully disabled from within the BIOS. This is an nForce2 chipset setting. So make sure to get an AGP card with 2xVGA (as most cards have nowadays).
    2) No or not much. Using an nForce2 MoBo myself I haven't encountered performance loss using both VGA outputs.
    3) There's no way to compare the onboard video to an AGP card. AGP cards will have a far out better perfomance then the onboard video. But compared to other onboard video solutions around, like Xtreme Graphics, the nForce solution is far better and has far better performance.
    It all depends on what you will be doing with the MegaPC. If you're a gamer, get an AGP card. If you want to use it as an HTPC, keep with the onboard nForce2 solution. There's no need for extra here since the nForce2 chipset is great. Onboard sound from this chipset is also great. Try it out before spending $ on an AGP card you don't need.
    Hope this helped a bit.

  • I have OSX 10.5.5 but my computer won't install OSX 10.5.8

    Why won't my macbook Pro install OSX 10.5.8?

    Some general advice on updating Leopard:
    It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
    So before you do anything else:
    If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
    Turn off sleep mode for both screen and hard disk.
    Disconnect all peripherals except your keyboard and mouse.
    1. Repair Permissions (in Disk Utility)
    2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
    At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
    3. Download the correct version of the COMBO update from the Apple download site.
    The Combo updater of Leopard 10.5.8 can be found here:
    http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
    If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
    Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606

    Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
    Now proceed as follows:
    4. Close all applications and turn off energy saving and screensaver.
    5. Unplug all peripherals except your keyboard and mouse.
    6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
    7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
    8. Once your Mac is awake, repair permissions again, and you should be good to go!
    If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
    9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
    N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
    Lastly, Apple's own article on the subject of Software Update may also be useful reading:

    [b]If you are updating Safari (or just have):[/b]
    Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up.  If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
    So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
    Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.

    To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for  problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
    Again, the advice is to remove all Input Managers from the following directories:
    /Library/InputManagers
    ~/Library/InputManagers
    especially prior to system updates (they can always be added back one-by-one later).
