  • [SOLVED] MacbookPro 8,1 13" - Dual boot with Mac OS X #rEFIt

    Hi everyone, I want to share my experience and request for help regarding my attempt to install Arch on my MBP 8,1. I can't count the times I've tried to install it this week.
    What have I done?
    So I followed the Beginner's Guide to aid me in the installation, with some exceptions:
    * I used Linux Mint 14 to use GParted. The reason I used it is because rEFIt won't sync the GPT and MBR tables properly when I try and use `mkfs.ext4 /dev/sdaX` inside the Archiso. With Archiso, the filesystem types are considered to be "Unknown" (#wtf no. 1), whereas with Mint that doesn't happen.
    * In fstab I had something like:
    # /dev/sda4
    UUID=c35d9121-a3f1-4cd6-ab53-61fe0f474eee / ext4 rw,noatime 0 1
    # /dev/sda5
    UUID=390185f6-6d55-430c-a9ba-d3d0b4c7798b /home ext4 rw,relatime,codepage=437 0 2
    The wiki mentioned the noatime and codepage flags for the respective partitions and so I complied.
    One thing to notice is I have no /boot mount because syslinux apparently doesn't like that.
    * Installing syslinux (along with gptfdisk), I issued:
    syslinux-install_update -iam
    , and reviewed /boot/syslinux/syslinux.cfg like this:
    LABEL arch
    MENU LABEL Arch Linux
    LINUX ../vmlinuz-linux
    ----APPEND root=/dev/disk/by-uuid/c35d9121-a3f1-4cd6-ab53-61fe0f474eee ro----
    APPEND root=/dev/disk/by-partuuid/c35d9121-a3f1-4cd6-ab53-61fe0f474eee ro **still doesn't work, it's not found**
    INITRD ../initramfs-linux.img
    LABEL archfallback
    MENU LABEL Arch Linux Fallback
    LINUX ../vmlinuz-linux
    ----APPEND root=/dev/disk/by-uuid/c35bod9121-a3f1-4cd6-ab53-61fe0f474eee ro----
    APPEND root=/dev/disk/by-partuuid/c35d9121-a3f1-4cd6-ab53-61fe0f474eee ro **still doesn't work, it's not found**
    INITRD ../initramfs-linux-fallback.img
    I used UUID's to avoid the mess on sdaX discrepancies.
    Results
    * rEFIt correctly shows Arch as a boot option. It boots correctly to Syslinux.
    * The kernel load fails due to something like:
    Unknown filesystem 'vfat'
    ... and/or ...
    Waiting 10 seconds for /dev/sdaX ...
    This stroke me as #wtf no.2. VFAT?? Has anyone experienced this before?
    For now this is all I have. I was hoping the community could give me helpful pointers on solving this as I intend to contribute with documentation on this setup in the wiki.
    I'll be updating this post with newer information. Thanks for helping!

    I don't have much experience with SYSLINUX or booting a Mac in BIOS mode, but I can help answer a couple of your questions and offer some alternative approaches....

    This issue is a limitation of the "gptsync" program that's included with rEFIt, not with rEFIt itself. It's also not caused by mkfs; gptsync doesn't even look inside the partitions, AFAIK. Instead, it looks at partition type codes. It understands just a few of them, including the one that all but the very latest versions of libparted use on Linux filesystem partitions. The trouble is that the libparted developers long ago "borrowed" that code from Windows, but they shouldn't have done so. That's being corrected, and gdisk can use the correct code for Linux ("8300" in gdisk). In the future, libparted will use this code, too; the support is already present but isn't yet widely distributed. You could have set the type code to "0700" in gdisk from Arch and gptsync would have worked.
    You may be interested to know that gdisk can do the same job that gptsync does, and gdisk can do so much more flexibly. You can read more in the gdisk hybrid MBR documentation. Be aware that hybrid MBRs (which is what gptsync creates) are ugly and dangerous hacks. Sadly, they're necessary to dual-boot Windows and OS X on Macs, but you may be able to dual-boot OS X and Linux without a hybrid MBR. The trick here is to install an EFI boot loader for Linux rather than a BIOS boot loader for Linux. Macs use EFI natively, so this is the superior way to get started, at least theoretically.
    The Arch wiki has a number of pages on EFI issues, such as:
    https://wiki.archlinux.org/index.php/Un … _Interface
    https://wiki.archlinux.org/index.php/UEFI_Bootloaders
    https://wiki.archlinux.org/index.php/GRUB_EFI_Examples
    The main problem with booting a Mac in EFI mode is that some systems won't activate all their hardware in this way, so with some models you can end up with a network adapter or video display or sound that doesn't work. Other models are fine, though; you'll just have to give it a try and see if it works.
    Personally, I think the best way to do it is to use the kernel's EFI stub loader in conjunction with an EFI boot manager like rEFInd or gummiboot. Both are available as Arch packages, but it's better to install from OS X, and that process is much better documented for rEFInd than for gummiboot (although you could adapt the rEFInd documentation for gummiboot, if you liked). rEFIt can work, too, but only if the kernel includes built-in command-line options and is renamed with a ".efi" extension. These are awkward requirements, and since rEFInd is a continuation of rEFIt development, there's not much point in trying to get rEFIt to do the job.

  • Wallstreet PCMCIA hard disk not booting with Mac OS X?!?

    Wanted to set up a PC Card disk drive as a servicing device.
    Installing and booting Mac OS 9 works fine.
    Installing Mac OS X 10.2 performs without problems too, but the PC Card disk drive refuses to do the initial boot, resulting in a blank screen (Mac OS 9 flavour) with the mouse freezed in the upper left corner.
    alt-ctrl-shift-fn done, PRAM-Reset too, even Open Firmware reset.
    Any clues or tricks I don´t know of?

    trabu,
    Welcome to the Discussions.
    I also have a PC card HD made by MCE which works fine in 9.x on my Wallstreet but not 10.x. Apparently the necessary drivers to support this interface are not included in 10.x. Since it was not a very widely used hardware configuration, Apple chose not to support it.
    Interestingly, it is firmware during startup, both in the powerbook and PC card, that allow these HDs to boot. Once the PC card HD initializes, something is missing in 10.x which prevents the boot to proceed. I also do not believe the 8GB limit for Wallstreets running OSX on internal HDs applies (see below).
    When I was booted to 10.2.4 on my Wallstreet, the PC card HD would mount on the desktop with a PC card icon and any attempt to open a file or folder on the PC card HD would result in a freeze. I believe I still had 9.x installed on the external HD.
    This is what MCE has to say:
    "(Note: While the Transport Pro FireWire/USB Kit is compatible with Mac OS 9 and Mac OS X, the Transport PC Card Kit is only compatible with Mac OS 9 and does not operate under Mac OS X.)"
    The only way to boot a Wallstreet from another HD is via the SCSI port or a media bay HD. You can still buy one for $69 without the HD:

  • Can I dual boot with MAC OS/X and Windows

    What is the best way to configure a dual boot on my MAC Bookpro laptop? Also, can I dual boot Windows 8 and MAC OS?

    The first alternative is a dual-boot arrangement between OS X and Windows provided with OS X.
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
         1. Install the Apple Boot Camp software.  Purchase Windows
             XP w/Service Pak2, Vista, or Windows 7.  For Boot Camp
             4.0 and above you can only use Windows 7 or later. Follow
             instructions in the Boot Camp documentation on
             installation of Boot Camp, creating Driver CD, and
             installing Windows.  Boot Camp enables you to boot the
             computer into OS X or Windows.
         2. Parallels Desktop for Mac and Windows XP, Vista Business,
             Vista Ultimate, or Windows 7.  Parallels is software
             virtualization that enables running Windows concurrently
             with OS X.
         3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
             or Windows 7.  VM Fusion is software virtualization that
             enables running Windows concurrently with OS X.
         4. CrossOver which enables running many Windows
             applications without having to install Windows.  The
             Windows applications can run concurrently with OS X.
         5. VirtualBox is an Open Source freeware virtual machine such
             as VM Fusion and Parallels that was developed by Solaris.
             It is not as fully developed for the Mac as Parallels and VM
             Fusion.
    Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

  • PowerMac G4 doesnt boot with Mac Os 9/Tiger

    Hi all, so I have a G3 and a G4. On the G3 I can boot without problems Mac OS 9 Retail, on the G4 instead I cant boot Mac OS 9 or Tiger (always Retail version).
    The only boot i can do on the G4 is Ubuntu...
    I tried so many ways, c, pram, reset-nvram/-all, installing Mac Os 9 on the hd by G3 but without solution...
    Some ideas?

    Hi, elect86 -
    Re OS 9 -
    Your G4 (Gigabit Ethernet) model can not use an OS 9.0 Install CD, nor an OS 9.2.2 Install CD.
    It originally came with a model-specific version of OS 9.0.4. It should be able to boot to the Software Install CD that came with it, which uses that OS.
    It should also be able to boot to and use a retail OS 9.1 or 9.2.1 Install CD. All retail OS 9 Install CDs have a white label with a large gold 9.
    It can not use any OS 9.2.2 Install CD - the only OS 9.2.2 install disks released were ones that shipped with certain Macs, and are model-specific to those machines. There has been no retail OS 9.2.2 Install CD released.
    Recommendation - if you do not have the original Software Install CD that came with your G4 (Gigabit Ethernet), obtain a retail OS 9.1 or 9.2.1 Install CD.
    Re OSX (Tiger) -
    If your disk set for Tiger is a retail set, it would have come on DVDs. If the optical drive on the G4 is not DVD bootable, then the DVD set will not work. There was (may still be) an exchange program for Tiger, to exchange the DVDs for a set of CDs.
    Another possibility in that regard is that the firmware on the G4 has not been updated to v. 4.2.8. This can be installed provided the machine has a bootable OS 9.1 (or later, but not OSX) installed on the hard drive.
    Article #120068 - G4 Firmware Update 4.2.8
    If by chance the Tiger install disk set that you have is one that came with a different model Mac, it will not be usable on your G4 (Gigabit Ethernet) machine.

  • Help: Syncing Curve 8330 with Mac OS 10.4!

    Hi... I posted something months ago, but never got an answer -- and REALLY need to fix this!
    Got Curve 8330s for my mother and myself in 08/2009 -- I have a PC, she has a Mac with OS 10.4 (Tiger).  She has NEVER been able to sync her BB with her Mac.  Pocket Mac didn't work, so she never got her contacts from her Yahoo account into her Curve, then DTM (finally) came out -- but since she doesn't have the right OS, we can't install that.
    So...
    1)  Can we do anything, short of spending another $500 to upgrade her OS to Snow Leopard?  (Oh yeah, she'd need to get more RAM at the same time to make that work... this just keeps getting better.)
    2)  Is DTM for Macs still wiping everyone's BlackBerrys?  Has this been fixed?  Or is this all a big waste of time?
    Needless to say, we're both quite unhappy to have spent so much time and effort on this (I'm her de facto IT person), especially after purchasing the devices and contracts so recently.  And I'm having my own issues over on the PC side. 
    We don't WANT iPhones.  We LIKE Verizon, and love having each having a BB -- but as others have said, it would be nice to make them actually talk to our computers... and we can't shell out any more money at all right now.
    Thanks in advance for your help!  And how do we actually get RIM to do anything about this issue?

    How did you come up with $500?  Is your friend on an intel mac?  If it is intel mac, the upgrade to SL is about $30.  The cost of ram is <$100.

  • Eternal booting with mac os 10.4.8

    Since the update to mac os 10.4.8 the booting of my MBP core duo, 1gb RAM, 35Gb / 100Gb HD is extremely slow. I already tried changing the start up disc from network to the internal hard drive. No results were there.
    has anybody have any solutions to this problem or any advises?
    thanks
    andres

    1. Is it possible your mac is searching for the network volume b4 it mounts the internal? Did you change the Startup Disk Sys Pref or boot holding alt? The former is the better and give a couple of restarts to properly exmine performance. Still slow?
    2. Disconnect Ethernet cable and peripherals. Still slow?
    3. Permissions Repair (Disk Utility). Still slow?
    4. Delete Login Items. Still slow?
    5. "Safe Boot" (shift on startup). Restart. Still slow?
    6.. Download and Install the Intel Mac OS 10.4.8 Combo Updater. Migrating from 4.7 to 4.8 through SWareUodate pulls down the smaller Delta Update. Running the Combo again can fix things.

    Then I have to restart and then it boots normally.

    I checked. Yes, Resume will cause Disk Utility to start upon restart under the condition I mention above. if you don't want windows open when shutting down to reopen upon restart, then uncheck the "Reopen windows when logging back in" box that appears after you chose to shut down.

  • 285 GTX Mac and Windows XP booting with Boot Camp - Black Screen

    I decided to update my 8800GT to the newer 285 GTX. Loaded the drivers, a must first, then installed the card. Booted the Mac and wow what an inprovement.
    Here's where the problems start. I used Boot Camp to boot to my Windows XP 32 install in Bay 2. Got the Windows Start Up screen then nothing but black.
    I reinstalled my 8800 GT and restarted the computer. I installed the latest nVidia drivers (190.38) in XP.
    I reinstalled the 285 GTX and tries again. Mac worked fine when I restarted in XP got the Windows startup screen then nothing but black.
    I could use some answers to solve this problem. I believe the 285 is supposed to work booting Windows from Boot Camp but I can't figure out how to make it work.
    Thanks in Advance

    I know I saw, and tried to help, someone else with the same questions. At that time I think tried to get them to use Driver Sweeper 2.0 and really uninstall drivers and any leftovers.
    So there should be another thread here, but maybe also on eVGA forum.
    And it doesn't make sense, unless XP or even Apple's leftover Boot Camp drivers. So look for Driver Sweeper 2.0, works better; and there is a thread on evga for removing graphic driver and upgrade.

    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.

  • External Hard drive help: use with mac and pc? how to backup everything etc

    Hello! I need some help regarding a new external hard drive I got from OWC. It is a 500 gb firewire 400 + usb 2.0 7200 rpm hard drive. I am running it from firewire. The software suggests the first thing you do is make a clone of your macbooks internal hard drive, that way if it fails later you can use the external to back everything up. If I do this ...
    1. do I have to make the drive "Bootable" ? I have software called Data Backup 3 by Pro soft I think. It came with my external.
    2. Can I still back up other stuff like my audio recordings and record onto that drive to a seperate folder?
    3. If I make a bootable copy will it try and boot from the drive everytime I turn it on or something?
    My other question is... how can I use this drive with a pc? I have a pc as well and I heard that the only way it will work is to format it in ms-dos mode (fat32?)
    If I write it to fat32 will it slow down my drive or make it worse? I heard that you should format external drives specifically for mac if you have a mac; so it will only work with macs...
    (sorry this is going on and on; it's like a chain reaction of questions)
    so If its formatted to mac drive format then can I do this with my current situation:
    1. I have wireless internet, the router is on a pc downstairs
    2. Can I send files over a network somehow from the pc to my mac
    3. then store it on my external?
    If so can someone point me in that direction with a link?
    Thank you for reading, sorry for making this so long.

    1. No, you don't have to make a bootable clone.
    2. If you use the drive for a bootable backup, then you cannot use the drive for other types of storage unless you partition the drive and make more than one volume.
    3. No, it will not try to boot the computer. You must designate the startup volume using Startup Disk preferences.
    If you wish to use the drive on both a Mac and a PC, then either you make two partitions - one for Mac and the other for the PC or you must format the entire drive using FAT32 so the drive can be used for read//write by both operating systems. If you do this then you cannot use the drive for a bootable backup nor can you use it with Time Machine.
    FAT32 is slower for read/write on the Mac than using Mac formatting.
    Optimally, I would suggest you partition the drive into two volumes. One volume formatted for the Mac and the other formatted FAT32.
    You can send files from a PC to a Mac and vice-versa using File Sharing. Select Mac Help from the Finder's Help menu and search for "file sharing" or "sharing" to find help articles. Also see,
