MacBook Pro Raid 1 Capability

Hi. Do I need extra software for my MBPro to implement RAID 1 on a set of external hardrives? 1TB WD My Book Studio Edition (Fire Wire 400 & 800; USB 2; eSATA) and 1TB Lacie (USB 2 only). Will these drives work as a RAID 1 set if one is USB only and other is Firewire?

OSX Server supports Software RAID but AFAIK ordinary OSX does not, and I don't know whether there is any software available to do this: you could Google. It sound unlikely that two totally unmatched disks would work, but it would depend on the software. The more usual solution is a hardware solution - doesn't the Western Digital support this option by itself? - of course you would get only 500GB that way.

  • Will Macbook Pro Core 2 Duo perform well enough with Mainstage.

    Hi there,
    I normally keep each of my macs for about 4-5 years before upgrading, and its about that time for me. I currently have a 2.5GHz Intel Core 2 Duo with 4GB Ram, and am leaning towards getting a new 27 inch imac for my home studio. My alternative is getting the 15 inch mac book pro retina, which I could still hook up to a large display at home, but also use for live performances.
    My question is has anyone had any experience running Mainstage (2 or 3) on a Core 2 Duo, and does it run it well enough to process reverb and maybe chorus for one vocalist, and a couple of guitar effects for an acoustic guitar?
    The reason I'm leaning towards the iMac, is because my configuration will likely be $400-600 less expensive than the macbook pro retina, the size of the screen, and the ease of not having to plugging a laptop into all my peripherals whenever I enter my studio. This will only be viable however, if my macbook pro is capable of handling mainstage duties.
    A couple of notes, I'm aware I can always get a external monitor for a macbrook pro, but am interested to hear anyone elses experience with either an intel core 2 duo running Mainstage, or your experience using an iMac vs a Macbook pro for your home studio.
    Thanks in advance!

    I have a mid-2009 MBP with a 2.53 GHz Core 2 Duo with 8 GB of RAM and MainStage 3.0.1 runs very well.  I recently played a pit orchestra job with Alicia's Keys as my primary piano sound from within MainStage and there were no problems (I did alias the patch throughout the show but that's just good resource useage). 
    I suspect you would have a similar experience on your current hardware.  Buy MainStage and try it out.  Its only $30 or so and you can run it on any Mac you own so you really won't waste the money. 
    Good luck!

  • How to check macbook pro for hdcp playback?

    HD videos on iTunes says that the hardware have to be HDCP capable.  Is the Macbook Pro HDCP capable?

    WHich MacBook Pro do you have? Most are - I download HD videos from iTunes all the time on my 2011 15" MBP and watch them in superb quaility on my 27" Apple Thunderbolt Display.

  • Can a MacBook Pro Export SXGA+ (1400-1050) display resolution?

    Can you tell me whether the MacBook Pro is capable of exporting SXGA+ (1400x1050) resolution via the Mini Display Port to VGA adapter for use with our high-end projectors?
    Thanks.
    Jan

    Sure. As long as it sees an EDID from the attached display that is requesting that format, the Mac will be happy to output it.

  • Macbook Pro Retina problem connecting to HP 23xi

    Hello Community,
    I've been experiencing a problem, I bought a 13' Macbook Pro Retina. Not quite a cheap machine.
    But when I connect through HDMI to my HP 23xi , the screen gets blurry and cut (which I was able to fix in the setting). I tried messing with the configurations, but it simply won't get better.
    I presume it's because it is retina, of course. But I bought this monitor, a quite nice monitor a month ago, and I do not want to sell it nor throw it away.
    I bought this Mac to do web design , but this is not the outcome I was expecting at all.
    I've seen the other post about the RGB fix, altough I haven't tried it because it isn't very pratical, my problem is not the color, but rather the pixelated resolution that appears on the display.
    What should I do?
    My Kindest Regards,
    Luisvf7

    Looking at the specs for the MacBook,
    Thunderbolt digital video output
    Native Mini DisplayPort output
    DVI output using Mini DisplayPort to DVI Adapter (sold separately)
    VGA output using Mini DisplayPort to VGA Adapter (sold separately)
    Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
    HDMI video output
    Support for 1080p resolution at up to 60Hz
    Support for 3840-by-2160 resolution at 30Hz
    Support for 4096-by-2160 resolution at 24Hz
     I would consider using a Mini DisplayPort to Dual-Link DVI adapter for Thunderbolt digital video. 
    You will not achieve the 2560 x 1600 display resolution that your MacBook Pro is capable of on your HP display as the display is not capable of that. Specs for the display

  • How do I rotate MacBook Pro screen 90/180 degrees?

    I have Mac OS X 10.4.11. Is it even possible?

    I believe all Macbook Pros are capable of rotating their internal display. Tiger may allow you to do that using System Preferences: Option-click on the Displays pane in System Preferences and a display rotation drop down box may appear.
    If that does not work, the Unix utility fb-rotate will. It is available here:
    http://modbookish.lefora.com/2010/06/29/a-unix-utility-to-change-the-primary-dis play-on-os/
    You probably have to re-compile the source (fb-rotate.c) for Tiger, but there are instructions on how to do that, and it is easy.

  • MacBook Pro Core 2 Duo 2.2 A1226

    Can anyone tell me if this Macbook Pro is capable of dual band?

    Louie is correct - your MBP supports 802.11a/b/g/n and can use both n-wireless frequencies.
    Note that the very early C2D MBPs running Tiger supported 802.11n only after application of the n-wireless enabler (a $2 purchase from Apple). But, the 2.2 GHz machine had it from the beginning, and the enabler was rolled into Leopard when it was released.

  • LaCie Desktop Manager doesn't recognize LaCie RAID with my 2011 MacBook Pro

    Hello,
    I have a new MacBook Pro 17" but I am not able to use the LaCie Desktop Manager with the LaCie 4big Quadra Enterprise Class RAID. The drive is recognized by the finder via eSATA, FireWire, USB, but is not recognized by the LaCie Desktop Manager. This prevents me from encrypting the drive. The LaCie Desktop Manager could recognize the raid with my early 2008 MacBook Pro.
    I'd like to know if anyone else is having the same problem with their 2011 MacBook Pro.
    I have been communicating with LaCie support but he tells me that he can't check the same or similar configuration as mine.
    Thanks,
    Dennis

    Looks like the cable is the same if you still have the 2010.

  • Striped RAID not recognized by Macbook Pro

    I have a pair of external firewire 250GB drives that I had configured into a striped RAID set on my Powerbook Titanium. I recently purchased a Macbook Pro. When I plug the drives into the new machine, they are not recognized and the array (and I use the term loosely since it only refers to a pair of drives!) will not mount. When I launch DIsk Utility, the drives appear in the list and are offline. I cannot find a way to bring the thing online.
    When I created the RAID, I used Mac OS Extended (Journaled) format. The disk set still works fine on my Powerbook and checks out fine with Disk Utility on that machine.
    Does anybody have any suggestions on how to use my striped set on my new machine?

    Hi, P. J.
    Unfortunately, I don't have an answer for you, but — seeing as how your question has gone unanswered — I thought I'd offer the following hypothesis: I suspect it may have something to do with the different partitioning schemes used by PPC and Intel-based Macs.
    Theoretically, "Any Macintosh computer running Mac OS X 10.4 and later can mount GPT-partitioned disks," per "Technical Note TN2166, "Secrets of the GPT." However, the RAID you created on your PPC-based Mac used the APM (Apple Partition Map) scheme.
    Perhaps all the bugs haven't been worked out, esp. concerning RAID. For example, there is a known issue that some Intel-based Macs cannot boot from RAID volumes.
    You may want to try your question on the MacBook Pro Discussion to see if others with your same Mac have had better luck. I'd also suggest providing more details (manufacturer, make, model, etc.) of the FireWire drives you've used in the RAID. If both are from the same manufacturer, then you might also want to check with the manufacturer to see if they've had similar reports.
    One option, albeit a good bit of work, would be to backup the contents of the RAID to another drive, then recreate the RAID on your Intel-based Mac, restore the data, and see if that works on both your PPC- and Intel-based Macs.
    Good luck!

  • Macbook Pro: How do I set up a RAID system?

    Macbook Pro: How do I set up a RAID system on a MACBOOK PRO properly?
    Can I have the OS on the same drives or does it need to be seperate?
    I mostly want to do this becuase I am having a lot of problems with the "spinning ball of death" and slow speeds.  I have my RAM maxed out at 6Gigs and my 7200rpm 750GB HD is about half full.
    Am I correct in trying to do an external RAID Drive to help with speed?
    If yes, what is the best way to do this and which type of connection (USB, Firewire, etc) is best to use?
    Thanks!

  • Macbook Pro with Dual hard drives. Scratch Disk, Memory 64bit, Raid, Set Up Questions.

    Hello, this is my first post.
    I just upgraded from the original 2006 17" Macbook Pro to a refurbished 13" Macbook Pro 2.53GHZ 4GB Ram (2009 model).
    I bought the MCE Tech Optibay and installed it (if you dont know anything about it, ask me, its amazing.) So now I have 2x 500GB 7200RPM Seagate hard drives installed.
    I am running Snow Leopard, CS3, Lightroom 1.4.
    I have the main hard drive set up with Snow Leopard and all the Applications. I keep all my files on external firewire 800 drives, except files I am currently working on.
    The second hard drive is set up as a scratch disk for Photoshop CS3 and that is it.
    I am looking to upgrade to CS5 and Lightroom 3 here within this month or so. Or if I get anxious, tomorrow, haha.
    I want to know the best setup I can do with my current set up with CS3 and for my future setup with CS5.
    Any info will appreciated.
    -Would some kind of raid set up with my internal drives be better? How does raid work with scratch disks?
    -If I upgrade to 8GB memory in my macbook pro, would I even see a difference in performance if I didn't have a scratch disk? Since CS5 and Snow Leopard can use more memory in 64bit.
    I think thats all I have on my brain right now. I may have more questions, or I can guarantee I will have more later.
    Thanks alot.

    First the scratch. Like you said, most everyone has a different take on scratch discs but I'd guess you're wasting one heck of a lot of hard drive space using all 500 GB for Scratch, did I read that right? If I did read it correctly YES, partition it and get some use out of it!!
    I've got a unibody MBP 2.93GHz, OS 10.5.8, CS3 & PS 5 (running in 32bit mode), and 8 gigs of ram. I've partitioned the one 300 GB drive so 50GB is scratch, the other partition is for OS, & Apps, and documents (images).
    I use LR 2 first than export to PS 5 to finish up. My photos get to be 300MB to 500MB in size and both versions of PS work on this setup just fine. Using PS 5 in 64 bit mode is faster opening files but NON of my plugin's are 64 bit yet, that's why I'm still stuck in 32 bit mode.
    Not knowing what size or kind of files you work on makes giving advice a bit tough but try setting the status indicator (don't know the right name for it) in the bottom left corner of any PS open file to "Efficiency" and watch what happens when you process your files. I rarely see mine drop below 90%, I've got the usable RAM in PS Prefs set to it's max suggested, cut way back on History and Cache.
    Can't wait for NIK and others to offer their plugin in 64 bit, later this year is what I was told.
    There used to be an old "rule of thumb" with old version of PS about Scratch disc size. I don't remember exactly but it may have been 3 to 5 times the size of your biggest file??
    Good luck, Alan

  • 17" MacBook Pro - Phillips 40" LCD TV 120 HZ Capable

    I have been hooking up my 17" Macbook Pro to a Phillips LCD TV capable of 120 HZ refresh rate. I am connecting the computer to the TV with an HDMI-DVI with the apple Mini-DVI adapter. Everything that is shown on the TV seems to delay just enough to notice it.
    For example, if I mirror the displays there is a split second delay from the pictures on the MacBook monitor to the Phillips TV. When watching movies, the MacBook will cut away from a scene just a hair before the Phillips picture will. This causes the audio to be off from the actual pictures just slightly.
    I am a graphic designer and like the extra space, but it is hard to manage putting things on the other screen because it has such a delay. The mouse is hard to operate because I am trying to compensate for the delay.
    Anyone have any suggestions. These are the settings I have for the Phillips TV and Display Prefs.
    Phillips TV Settings
    120 HZ refresh rate: OFF (It will not allow me to turn it on so it defualts to 60 HZ)
    MacBook Display Prefs
    60 HZ (NTSC)
    1080p
    Rotation Standard
    Overscan: On
    I've tried everything from changing the HDMI port I'm using to changing the resolution of the screen.
    Is there anyway to fix this?
    Thanks,
    Chris

    Usually there is a GAME mode on modern TVs. It turns off all the "features" that can cause latency in the pipeline to the screen. This matters a lot to gamers.
    So see if your TV has game mode and if that helps the situation.

  • Macbook Pro Wireless HDMI capability?

    I have read that using a device that plugs into your TV's HDMI port you can stream HD audio and video from your laptop to the TV.
    To do this the article said your laptop would need to have "wireless HDMI capability".
    Does the new Macbook Pro have this capability?

    Perhaps there will soon be a combination of MBP and some sort of external third-party adapter that will enable this capability in the future, but to the best of my knowledge it doesn't exist now.

  • RAID drives with MacBook Pro?

    Do I  need a RAID card in my MacBook Pro to use external 800 firewire RAID Lacie drives with a 5+ array?
    Thank you,
    Patrice Shannon

    Dear RedRocket,
    Thank you for your response.  I will try this.  AussieDJ said I should use eSATA but I don't know if my MacBook Pro supports that? have to do more research.  I've used external firewire 800 before with my laptop but never a RAID.  I decided to go this route for data safety since I'm starting a new project soon.
    I just bought
    LaCie 4big Quadra
    4-BAY RAID I USB 2.0 I FireWire 400 & 800 I eSATA
    I hope it works okay with the MacBook and firewire 800.  I'm going to be editing an Avid project in AppleProRes 422.
    If it doesn't work properly, I guess I'll just invest in a desktop with eSATA.
    Best Regards,
    Patrice Shannon
