Expresscard 34 Port. Do I have version 1 or version 2.0 on my Macbook Pro

Hi,
Would like to know which version of Expresscard 34 I have on my Macbook Pro 17" (unibody core-duo) early 2009, currently running Snow Leopard 10.6.4.
Would it be version 1 only (and restricted if hardware based only)?
OR would the heavens have smiled and possibly be version 2.0 expresscard standard (having 5Gbit/s bandwidth capability) from maybe a recent firmware update within a recent OSX update?
Any advice appreciated, thanx.
(references: http://en.wikipedia.org/wiki/ExpressCard#ExpressCard_2.0 )

No one knows?
Reason for needing to know this, is for making an informed decision for having an interface, i.e.:-
Possible SATA II interface. SATA II is I believe 3 gigabit and most express-card 34 adapters out there have 2x SATA II ports to use which equals 6 gigabit combined bandwidth through the express card.
Therefore if the Mac's express-card 34 port is Version 1, then according to some data sheet references for Version 1 specification it is 2.5 gigabit throughput (or 480Mbps if operating USB mode), which would be pointless benefitting from 2x SATA II connections on an express-card inserted into a mac.
If however the Express card 34 port on the Mac is Version 2, then version 2 is stated as having 5 gigabit bandwidth/throughput which would not impune the benefits of having two SATA II connections for external drives i.e. for HD video editing.
Does anyone know?

    When I try to download the new version of firefox my computer (MacBook Pro) tells me I don't have enough priveleges to carry this out

    If there are problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
    Download a new copy of the Firefox program and save the disk image (dmg) file to the desktop
    *Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
    *Trash the current Firefox application to do a clean (re-)install
    *Install the new version that you have downloaded
    Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data if you uninstall and (re)install Firefox.

    This is a copy of ONEof the keys  in the registry I changed  as told by Apple support today. I also have changed others as instructed by GEAR  software support to manually delete GEAR drivers (that I had installed but couldn't delete some of the others  they mentioned from Windows system 32. Then some bright spark at work told me I need the Gear drivers so  I downloaded the software and installed again.
    Sorry, just this minute went to insert image  and it is giving me a message saying this sort of content  is not allowed?.

    I have a Serial Number which worked fine on my MacBook Pro but does not work on my desktop PC (Win 7).  What is the problem?

    You haven't identified the version so I can't tell if offering you contact options for Adobe Support will be of use to you.  But they will likely be your only hope of getting resolution unless you just happen to be using the wrong number as the serial number.

  • Have 2 IPods Want Transfer from First Gen to MacBook Pro but using 4th Gen

    Have old 1st gen Ipod with music on it. I have a 4th Gen Ipod that I use with MacBook Pro. Wont let me transfer music from 1st gen to new computer. Old computer sold to buy new one. Any ideas??

    Try Senuti.
    It's a program that transfers music from iPod to iTunes on a Mac.
    There's also a similar program called Yamipod which has a Mac version.
    I've used both these on a Mac with great success.

  • I have PS 4,5,and 6 installed on my Macbook Pro as well as Lightroom 4 and 5. Can I remove PS 4 and 5 and LR 4?  PS 4 is the total install and PS 5 and 6 are upgrades. LR 4 is the full package with LR an upgrade.

    I need space!

    First let me disabuse of a misconception:  All Adobe upgrades are FULL installers.  Whether you buy them as upgrades or new versions does not make an iota of difference.  The upgrade installers do not need to find a prior version installed, they just prompt you for the old serial number as well as the old one, and they do not rely on the old version in the least.
    Second, the time to uninstall an older version is BEFORE upgrading to a newer one.  Otherwise, the uninstaller from the older versions will mess up with your new install.  There are a gazillion files that are named the same and in the same locations as the new one.
    Your best bet now is to uninstall ALL the Photoshop versions you have installed, including the newest one, one by one, then run the Adobe CS Cleaner Tool, then run Repair Permissions from Apple's Desk Utility, and finally re-install the latest version.
    The other alternative, if your boot HD is large enough (very doubtful in case of a laptop like a Mac Book), is to leave all versions on it.
    Your choice.

    > during the entirety of this process the cursor was a "busy" pinwheel/beach ball/whathaveyou for a solid 30 minutes before I turned the computer off with the power button.
    All that cursor means is that it is busy trying to do something.  You can see if force quitting solves the problem with a simple force quit using command-option-escape.  If you are having issues with iCal quitting, sometimes it doesn't always know whether or not it is properly communicating with a particular calendar.  This can be a Mobileme issue, or even a phone synchronization issue, or a network issue reaching a shared calendar.  Shutting down a machine directly from a cursor is the last step one should try, only after all others have failed.  If you have done this in the past, lurking corruption can get worse each time with the directory, and upgrading the system will only enhance any corruption already present.  When you restart your Mac, does everything appear to be normal?

    Upgrading to Yosemite
    You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
    Upgrading to Yosemite
    To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
        OS X Mavericks- System Requirements
          Macs that can be upgraded to OS X Yosemite
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later

  • This Question is at least 2.5 years old.  But still an issue.  I have an early 2008 and mid 2010 13 inch macbook pro running iTunes 10.7.  Itunes on both machines doesn't recognize blank cds or allow me to import from a music cd when I insert it.

    iTunes does not use the .xml it uses the .itl
    If you are sure your old library file migrated across (does the file size and modification dates suggest it has?) start iTunes while holding down the option/alt key and guide it to the .itl file to get it to use that one.

    Connect the device to the computer.
    In iTunes, select the content desired to sync.

  • I have installed a trial of Adobe illustrator on my macbook pro. I want to trace an image using the custom trace button but can't. Does anyone have any ideas how I could custom trace?

    I have installed a trial of Adobe illustrator on my macbook pro. It is the 2014 release of adobe illustrator. I want to trace an image using the custom trace button.
    I start a new document. Then I place my scanned pencil/colored pencil drawing, in to the document. I have tried scanning and then placing it as a jpeg, bitmap, and tiff file. I have tried scanning and then placing it, in color and in black and white. The scan mode I use is flatbed. Adobe illustrator allows me to select the default button and one of eleven preset buttons (e.g high fidelity photo), but it does not allow me to click the custom trace button. The custom trace button is grey while all the other buttons are white.
    Does anyone have any ideas how I could custom trace?

    It seems pointless to adjust it afterwards because it is then only a couple a pencil lines rather then a full drawing. And how do I adjust it afterwards? Would I do this using the different buttons under the window button?

  • After i have downloaded an album from iCloud to my new macbook pro. Itunes will only play one song at a time. If i hit the fast forward or back button will not do anything. I have to use the mouse to hit the next tidal in the album then hit play for it

    after i have downloaded an album from iCloud to my new macbook pro. Itunes will only play one song at a time. If i hit the fast forward or back button will not do anything. I have to use the mouse to hit the next tidal in the album then hit play for it to play the next song. Or put it in the UP NEXT.

    First, make sure these items have checkmarks next to their names in iTunes. Continuous playback only works on checked items. Itunes will play all checked items in a list whether or not they're from the same album.
    If you see that nothing in your library is checked and you want to check everything, hold down Ctrl while checking an item. This checks everything.
    Next, fixing the "1 of 1" problem is easily. Select all the tracks that make up the book/album. Let's say there are 15. Press Ctrl-I. Doublecheck that the album box is filled in with the name of the book, and if not, type it there. Enter "15" in the box for the total number of tracks. Click OK. Now all the items should be "1 of 15," "2 of 15," and so on.

  • HT1338 When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

    When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

    There are many people suffering from this problem right now (including me). It appears to be a server issue. Just wait and try checking for updates again tomorrow.
    Some things I have heard indicate that this may be a regional problem, though what parts of the world are affected I don't know yet. A few people have been helped by deleting the following preference file (paste the path into the Go -> Go to Folder window in the Finder to locate it), though most have not:
    ~/Library/Preferences/com.apple.SoftwareUpdate.plist
    Note that if you are trying to download iTunes 10.7, that can be found here:
    http://support.apple.com/kb/DL1576
    Also, note that there is no reason to be anxious to get it, as the only thing added in iTunes 10.7 is compatibility with iOS 6, which will not be available until the 19th, and the new iPhone, which will not be available until later as well. The new iTunes that was announced is iTunes 11, which is also not yet available.
