Leopard and Express34 drivers

After installing Leopard, the MBPro will boot and run successfully only if I remove my eSATA II Dual Ports Express Card/34 Host from the slot. If I insert this card, the machine crashes. I have looked on the internet at Silicon Image for the latest drivers for Si3132 chipset and there is nothing new (I downloaded and tried 1.1.9 and 1.5.16 just for drill, but it doesn't change the problem. I think I was running 1.1.9 which I downloaded last December when I set it up). Now I can't access my RAID 10 array with all my Final Cut Pro capture scratch files. Is there a workaround? Pending a new Si driver, is there any info on Express34 drivers for Leopard? Thanks. Andy. Happy Holidays.

The vendor's website has the same info from a year ago ... the actual manuf. of the board is unknown, no name on it ... uses Silicon Image chipset ... but there is no driver update for Leopard. The vendor is a small company that makes enclosures and SATA cables and has poor Mac support. I'm not going to waste my time.
I mistakenly posted this in the wrong sub-forum ... but don't know how to make it go away.
I ordered a new board from Sonnet.

  • Snow Leopard and Windows 7 - Unable to locate CD/DVD drivers to install

    hi,
    I am using Boot Camp to install Windows 7, and when the installation starts, I get an error message/ popup window that states: "Unable to locate CD/DVD drivers...".
    I can't eject the CD, or figure out which drivers it needs, & how to get them.
    I've noticed a lot of people are having this same issue with various PC manufacturers and various releases of Windows 7...
    Some people have successfully avoided this by installing off of a USB drive. I am wondering if it's at all possible to install Windows 7 / Boot Camp with a USB drive... or if there is another solution to this problem.
    thanks
    ben

    hi,
    i'm replying again to my own question with more info
    basically i inserted the snow leopard and the mac os x install dvd's that shipped with my early 2009 nehalem mac pro tower into a windows machine. i was able to "explore" the dvd using windows and found some boot camp support folders which contained drivers.
    i copied these drivers to a thumb drive.
    so now, during the windows 7 install... i have the option of navigating to these drivers on my thumb drive.
    however - i don't see any potential drivers for the dvd burner/ superdrive...
    here is the list of companies/ drivers supplied:
    ATI
    Broadcom
    Marvell
    Apple
    Cirrus
    MotorolaSetup.exe
    Asix
    IDT SigmaTel
    NVidia
    Atheros
    Intel
    RealTekSetup.exe
    it is my understanding that the superdrive is hitachi...
    the information on this drive inside the system profiler is as follows:
    "HL-DT-ST DVD-RW GH41N:
    Firmware Revision: PQ05
    Interconnect: ATAPI
    Burn Support: Yes (Apple Shipping Drive)
    Cache: 2048 KB
    Reads DVD: Yes
    CD-Write: -R, -RW
    DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
    Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
    Media: Insert media and refresh to show available burn speeds"
    i really wish i knew more info about this drive and where to get windows drivers for it so i can install windows 7 on my mac pro.
    this is the stock drive that shipped with this mac pro. i find it strange that no one else is running into this issue?
    thanks

  • Snow Leopard and GSM Modems (Vodafone)

    I'm not sure if this is the proper place to post this, but I'd like to share my experience with GSM (GPRS/3G) modems and Mac OS X. The main reason for doing this is the fact that I wasn't able to find any related information for my issues on the web and I think I'm not the only one with those issues. Feel free to post any feedback here
    Few months ago I started using a 3G modem with my Macbook Air. The service provider is Vodafone and the modem is incorrectly marketed by Vodafone on the web as a Huawei device (E169), but it is a ZTE K3656-Z modem (I'm not sure if the companies are different or if the hardware is, in fact, different, but the kernel module is definitely different :D).
    The first thing that annoyed me is the Vodafone Mobile Connect application. The 'response time' between plugging in the modem and actually getting online is quite big, and I really wanted to get it out of my way. I'm not using any SMS functionality, so from my point of view, the application was totally pointless. When you plug in the modem, it acts as an external CD Drive. If the Vodafone Mobile Connect application is installed, it will automatically eject (unmount) the drive. Unfortunately,
    this usually (not all the time, but quite often) generates a crash in diskutil (quite annoying).
    But what annoyed me the most, was the fact that, when online, the Vodafone application was taking at least 35% of my CPU. Now, this is unacceptable Under normal load (Safari, Adium), this was quite acceptable. But under slightly higher load, the CPU was getting quite hot, causing the kernel_task to try to slow down the system (and cool down the CPU) by taking about 135% of CPU (according to Activity Monitor) and making the system unusable. Of course, another side effect was the cooler running at 6400 RPM, faster battery drain and generally, making the system quite unusable. My 1st Generation Macbook Air wasn't able to deal with all that
    When I first saw the high CPU usage by the Vodafone application, I immediately thought of the old 56Kb WinModems Back then, it was quite a common practice to develop modems that would use the CPU to compress/decompress or process the data/sound in order to make the modem as cheap as possible, but inflicting a huge system slow down - Yes, I'm that old :P
    Given that experience with those modems, I figured that the Vodafone application was somehow doing that as a 'user space module' Boy, was I wrong
    So, this is what I did: First of all, you need to properly identify the GSM modem. In order to do this (no Terminal involved) is to set up connection using Vodafone Mobile Connect, then using the System Preferences, head over to Network and check the available interfaces (no, this is not a tutorial, but a guide :P ). You should see either a Huawei Modem or ZTEUSBModem/ZTEUSBATPort. Keep in mind the modem you have, then disconnect. At this point, you need to use the Vodafone application to change the PIN settings on your SIM card. Use the application (Preferences -> PIN) and disable PIN check. Now you can safely remove the Vodafone application
    The second step is to install the proper modules/drivers/kexts for this. You can either get them from the web (at this point, you already know what modem you have) or you can use the packages located inside the Vodafone Mobile Connect application installer. To do this, simply use 'Show Contents' of the installer, then locate the packages (pkg) inside the Resources folder for your modem (the names are quite clear :P). Install that package and you'll have the modem drivers installed on your system.
    Once the modem drivers are installed, when you connect the GSM modem, the external CD Drive will 'mount'. Eject it and wait a little bit (few seconds) until the SIM card is initialized and the modem is available. Go to System Preferences -> Network and add a new interface using ZTEUSBModem (not ZTEUSBATPort). Set it up as a Generic Modem, GPRS Modem and configure it with your provider settings (APN, username, password). Set the dial up number as *99# (you can find a lot of tutorials on the web about setting this up - the tricky part was installing the proper modules and disabling the PIN check). You may now connect.
    The downside of this is the fact that you need to manually eject the drive when connecting the modem, otherwise you won't get the modem functionality, no SMS functionality and no PIN security.
    The upside is a very quiet system (the fan runs at 2400 RPM as opposed to 6400 RPM), a fast one (I can't see any noticeable slow down at all) and better battery life time.
    I'm not sure what is the effect on other systems, but my 1st Generation Macbook Air was totally unusable after few minutes of online time. Now it works perfectly
    I really hope that this is useful for other people Feel free to ask any question, I'm aware that my 'tutorial' skills are quite poor :P

    Oh, I forgot to mention: This works both on Leopard and Snow Leopard (tested on both systems). I've used the modem drivers located inside the Vodafone Mobile Connect installer (I couldn't find any ZTE modem drivers on the web).

  • New MacBook Pro 10.7.2 trying to connect to HP laserjet 1200 w wireless. Tried generic driver and hpdriver and gutenprint drivers. "Unable to connect due to error". Deleted prefs, restarted etc. Any ideas ?

    Just purchased a MacBook Pro OS 10.7.2. Cannot get it to print with HP LaserJet 1200.
    Connection is wireless, able to ping printer. (also tried  MacBook using ethernet).
    This HP 1200 prints perfectly with another mac running Snow Leopard.
    Tried HP 1200 driver, which, according to HP,  is not working with 10.7.2; They suggested Gutenprint
    tried generic printer from Mac, (message was printer is busy);
    tried CUPS Gutenprint 5.0.2,(message says "unable to connect due to an error"
    removed preferences and re-added printer, rebooted etc.  
    Any thoughts? I thought it was the driver, maybe there are other drivers out there or maybe it's something else???? Thanks

    Thanks for the replys.
    After spending an hour plus, uninstalling and reinstalling drivers and still not able to print, my husband, sits down, plugs in an ethernet cable, reinstalls the printer with the ip, and it prints. !!! I'd already done that , but that was before I deleted the preferences and installed the Gutenprint driver. I think it was the new Gutenprint driver that did it.

  • M1536DNF Duplex garbled mess, Lion, Snow Leopard and Win 7

    I've had my M1536DNF for about a year now, everything has been fine, great printer, no issues whatsoever until recently.
    I attempted to print some flight information, set it for 2 sided and thought nothing of it, went over to collect print job, the sides facing me are fine, the back side was almost entirely horizontal lines, some text did print top and bottom though. Exactly the same result on second attempt. As I was going away, I didn't have time to mess with it so I printed single sided and promptly forgot about it. This was with a Mac OSX Lion.
    Month or so later, my partner was trying to print a document from her Win 7 laptop, same issues, multiple attempts and nothing useful on the back side. Transferred the files to another Mac - Snow Leopard and still same issues.
    I've re-booted the printer, cleaned the printer, downloaded new drivers (which are not available for Lion yet so I don't know how this thing is working at all). Nothing seems to get it up and running again properly. Has something died on my printer or is this a software issue. I'm guessing hardware as the issue is 100% reproduceable from multiple machines, multiple operating systems.
    At no point have I seen an error from the printer or print utility.

    Scratch all of that. The issue is Chrome - the beta print panel seems to destroy the duplex side.
    Turn it off with these instructions.

  • How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?

    How do I partition my MacBook Pro so I can keep Snow Leopard and also install Mountain Lion?
    I want to install the latest OS, but I already know that I will lose a lot of my software unless I can partition the hard drive and have two "bootable" drives.
    How do I retain everything I have, partition the drive, then reloa the software I own according to which OS it will work under?

    I do not currently own OS X ML.
    I am currently running OS X (10.6.8 Snow Leopard) on my MacBook Pro. It has a 2.8GHz Intel Core 2 Duo Processor. I want to upgrade to Mountain Lion, but many of my software titles will not operate with ML and I cannot afford to replace some of them (Adobe Creative Suite, for e.g.)
    After I back-up my HD and then partition the HD, how do I use the back-up to reinstall what I want to the SL partition, and then place the rest on the ML partition.
    I have not done what you want to do, so can only offer some general thoughts in support. Take value from the following where you can. No guarantees.
    If it was me, I would use a disk clone utility (e.g. Carbon Copy Cloner) to image the existing Snow Leopard disk to an external drive. Then verify that the external drive would boot and run Snow Leopard normally.
    I would then purchase and download the Mountain Lion upgrade installer, but not run it. Use Lion Diskmaker to make a bootable USB stick, and perform a clean install of Mountain Lion, replacing the Snow Leopard on your MBP. This way, you make absolutely certain that no third-party drivers or other SL cruft remains to make Mountain Lion unstable. Update to latest ML point release. Fix permissions. Let TimeMachine make a full backup of your ML installation to a different external drive. Then turn of Time Machine.
    In Disk Utility, use the + sign at the bottom of the ML partition to add another GUID, HFS+ Journaled partition for Snow Leopard. Resize to taste. Name it differently from your ML partition. Exhale.
    Now ideally, you would like to reverse the external clone and put it back into the new SL partition. Then fix permissions. And demonstrate that you can boot into individually stable OS X installations. This would save you alot of work. Resist copying your home directory into ML just yet.
    If you cannot successfully achieve the preceding paragraph, you will be faced with a full SL and application reinstall.
    The ~/Library contents for SL and ML are sufficiently different that you do not want to mix them. You may want to salvage Safari bookmarks.plist. And, ML created folders in the home directory may have different permissions or ACL settings than in SL. So, my rule of thumb would be to copy folders that you created in SL, and only the contents of matching named OS created folders such as Music, Pictures, Downloads, etc.
    For each operating system, you probably want the Time Machine settings to exclude the opposite OS X partition. If you use the same host name in Sharing prefs, then you will mix SL and ML backups on the same Time Machine back up drive. If you use different host names, they will be distinct folders in the Time Machine backups.backupdb and allow discrete restores per host. You may also want to gag Spotlight from indexing the opposite OS X partition.

  • Printer profiles with LR 1.3, Leopard and R800

    Hi all. I'm printing from LR 1.3 in Leopard to an Epson R800. I've downloaded and installed the updated print driver from Epson (3.09). when I try to load a color profile I get:
    "The custom profile selected for this print job is missing or invalid. If you continue this print job, the colors will not be managed by Lightroom."
    It gives me the option of continuing, which I did not take advantage of. The driver works and prints look good when they're managed by printer, so I could just stick with that. But I thought I'd try to figure out what's going on and maybe learn something in the process. I've read through some other threads, seen talk of Carbon vs. Cocoa, but some of it goes over my head. So here's my questions, and forgive me if I sound dumb, but you know the old saying, there's no such thing as a dumb questions, only dumb answers:
    Are the profiles separate from the driver? Do I have to download new profiles for Leopard / LR 1.3? Are there new profiles anywhere? or how do I figure out what happened to the old profiles, which worked in Tiger? What is the advantage of letting the app manage colors instead of the printer anyway?
    Thanks in advance. With your help, I'm finally getting my workflow back to where it was before this Leopard thing!
    Regards,
    Dave

    John,
    In the case of the R800, 3.0 has been around for about one year. However, 3.09 was first posted to Epson Europe on 29 October 07 and 6 November 07 to Epson Oceania (Australia and New Zealand). The driver is supposed to be fully compatible with Leopard, but I have no way of checking. According to both Europe and Oceania, drivers for the remaining R series printers (1800, 1900 and 2400) are due out later this month.

  • Best Practice for Installation of Both Leopard and Aperture 2 upgrade.

    I've finally bought the bullet and purchased both Leopard and Aperture 2.0 upgrade. I've tried searching for a best practice to install both, but haven't been able to find one--only trouble shooting type stuff. Any suggestions, things to avoid, etc would be greatly appreciated. Even a gentle shove to a prior thread would be helpful. . . .
    Thanks for pointing me in the right direction.

    • First be really sure that all your apps work well with 10.5.3 before you leave 10.4.11, which is extraordinarily stable.
    • Immediately prior to and immediately after every installation of any kind (OS, apps, drivers, etc.) got to Utilities/Disk Utility/First Aid, and Repair Permissions. Repairing Permissions is not a problem fixer per se, but anecdotally many folks with heavy graphics installations (including me) who follow that protocol seem to maintain better operating environments under the challenge of heavy graphics than folks who do not diligently do so.
    • When you upgrade the OS do a "clean install."
    • RAM is relatively inexpensive and 2 GB RAM is limiting. I recommend adding 4x2 GB RAM. One good source is OWC: http://www.owcomputing.com/.
    • After you do your installations check for updates to the OS and/or Aperture, and perform any upgrades. Remember to Repair Permissions immediately prior to and immediately after the upgrade installations.
    • If you are looking for further Aperture performance improvement, consider the Radeon HD 3870. Reviews at http://www.barefeats.com/harper16.html and at http://www.barefeats.com/harper17.html.

  • Windows 7 Wireless and Audio Drivers on 2010 MacBook Pro

    I have a new MacBook Pro i7 2.66 Mhz with Snow Leopard and dual boot to Windows 7 64 bit Ultimate. I can't find the correct drivers (Windows 7 side) to get the audio and the wireless networking operating. I ran the bootcamp setup from the Snow Leopard install disc on Windows 7. It gave an error message that this model is not supported. I then ran each software driver individually from the install disc and was able to get all to work except the audio and wireless. I then installed the Bootcamp 3.2 update from the Internet with no improvement.
    Does anybody know where the audio and wireless drivers can be located for Windows 7? (Apple Support has not been able to resolve the problem yet) Thank You!

    I'm having the same problem with Windows 7 64-bit Professional. I had to go through the same process to get most of the drivers installed. I've had the same issues with the wireless and audio drivers.
    To get the Apple drivers installed, I followed the instructions from this blog post.

  • Since installing Snow Leopard and Lion two weeks ago, my iTunes program opens seemingly at will.  It usually starts playing music, too.  What is causing this?

    Since installing Snow Leopard and then Lion on my Intel-based iMac two weeks ago, my iTunes program seems to open at will whenever the computer is on.   It often begins playing music, as well.  What is causing this and how do I make it stop?

    There are ways to minimize, mitigate, and help avoid a lot of problems.
    Bootable backups.
    Zeroing a drive twice before using, and format it with SL DVD Apple Disk Utility for sure.
    Even a clean install should import old apps without having to reauthorize.
    If you must do an upgrade, do it from the SL DVD, after repairing the drive and be sure to use the SL version of Alsoft Disk Warrior (4.2).
    Wait six months before jumping on a new OS.
    10% is still too many. Yes, it is more sensitive to RAM and hard drive errors, doesn't like some controllers; most ext hdd cases; and enough software to make for test-only status. And it only IDs some known incompatible applications, drivers, extensions, etc and does not remove even those always in best manner.
    Plus, there are problems with the new Rosetta and the cache files it now uses. So some apps and plug-ins will cause more trouble. Not all are ready. Good reason to hold off for the months it takes.
    Other devices act different as far as on/off behavior.
    (Migrating from G5s to Mac Pro can cause all kinds of problems, weird behavior, sluggish system, and why anyone that went down that road was strongly recommended to NOT use Migration Assistant for any of their applications, and to ONLY do clean/fresh installs of any apps. If you skipped that day, didn't read the Guide to M.A., or didn't want to do fresh installs then, your system could have been on borrowed time. If you did do clean install of applications, great.
    Installing SL can result in a corrupt directory - I think and it "seems" to be happening, but no real proof, just gut feeling and instinct (underlying file system problem? weak sectors that pre-existed waiting to happen?).
    Remember all the "there just aren't a lot of 64-bit drivers" for Vista and XP? it's come home to roost.
    ... my guess is not enough incense and offerings. To hop into TimeMachine and SuperDuper backup images and pull the 1TB for another day (week, month, year).

  • Can't duplex print B4 paper size with Snow Leopard and HP8100N

    Apple print drivers dumped the standard European paper size B4 (see ISO 216 for specs) many OS's ago, however, I was able to duplex print B4, which is a standard size for the HP8100 trays, using the HP Duplexing accessory, by specifying a 'custom' paper size (10.14 x 14.33). Now, with Snow Leopard and the 10.6.4 and the updated HP8100 print driver from Apple, I get the message "The Duplex Option, Flip on Short Edge" is not available when the destination paper is set to Custom."
    It seems the easiest solution would be for Apple to bring back the B4 paper size--I don't know why they eliminated it. The next solution would be for Apple or HP (whoever is responisble for the print driver) to back up to whatever allowed duplexing of custom sizes in all recent OS's up to Snow Leopard.
    I have thousands of pages of music to print and manual duplexing just isn't an option. Anybody have any work-around ideas?

  • Color management problem (Leopard) and 1.3.1

    I am getting good screen to print match with Photoshop CS3 printing with Leopard and the new Epson drivers, but Lightroom 1.3.1 prints like there is no, or very bad color management. The older (1.2) version on another computer prints fine. I am using the same custom profile and the same printer settings on an Epson Stylus Pro 4000.
    Thanks,
    Peter

    Thanks so much for the straight forward explanation my friend! Much appreciated. I've been pulling my hair out over this.
    When I got to around 20,000 10MP images (D200) in Lightroom on my 4 year old Powerbook G4 17inch (with two 500GB external drives of course ;-) and a hardware calibrated 22inch Viewsonic VG2230wm LCD), she started to give me the dreaded "pizza of death" far too often and I'd lose 30 minutes of work here and there. Very frustrating. So I recently (about 2 weeks ago) bought the MacBookPro 15inch (2.4Ghz, 250HD) with Leopard pre-installed. I'd gotten so used to printing straight out of LR 90% of the time, that when I finally got everything migrated and went for my first print a couple days ago, I was heartbroken (not to mention, in-a-panic with clients waiting!). Fortunately CS3 still printed flawlessly, but it was far more time consuming to have to create a separate (stacked) PSD file (and eat up additional HD space).
    Anyway, I don't know why I'm telling you all this except I feel you probably can empathize with my situation, and your answer has at least put me at ease to know that it isn't some stupid move on MY part that has caused my meticulously built color management house of cards to suddenly crumble into a pile of *hit overnight! ;-) It makes me realize how much emotion I have invested in all the late nights striving for color perfection.
    Speaking of late nights, it's after 1am here (Washington state) so I better wrap this for now. but a big thank you goes your way! And as a closing note, your 3800 comment has caused me to spend the last few hours doing research and I discovered that Epson has announced it is doing a year end clearance on the 7800 for $2000 so I'm seriously thinking about heating up one of the pieces of plastic in my wallet tomorrow morning and biting the bullet on a serious 24 inch printer. I can't really afford it right now, but that's never stopped me in the past! hehheh If I've learned any damn thing in my 53 years on this planet, it's that sometimes ya just gotta step up to the plate and swing! And this one is all your fault, you *astard! *just kidding* Hope to see ya around.
    Cheers,

  • 64-Bit and 32-Bit: Snow Leopard and Windows 7

    Hi All:
    I will eventually be dual booting Snow Leopard and Windows 7. I have never used Boot Camp before and have several questions, including one related to Boot Camp.
    First, when installing 7, will I need to format the 7 partition, presumably NTSF.
    Second, given my MBP's 64-bit architecture, will I be able to run 64-bit 7. I am aware, of course, that not many programs are available in 64-bit for either platform. Also, I know that the Snow Leopard renditions of all, or most, of the iLife programs will be 64-bit.
    Does Leopard (and will Snow Leopard) run 32-bit programs in an emulation mode similar to the way 64-bit Vista/7 run 32-bit programs. In this regard, I assume, which surely must be the case, that OS X is a 64-bit program.

    hi donv,
    i run win7rc1 via bootcamp 32bit on mbp 17" 3.06ghz
    and same, but 64bit on imac 3.06ghz.
    all works perfect, also apple's keyboard (brightness+-/sound +-/keyboardbcklight +-/eject ..
    format is ntfs; backupable with winclone, also now (i have cloned from ssd to ssd).
    apps run also in emulation, but where specified drivers are needed (e.g. for flashing ci-cards) 32bit are a must (therefore i have 32bit on my mbp).
    partly i have boot camp 3.0 drivers (snowleo) in the mbp ..

  • Snow Leopard and Canon MX860 ... More help please!

    I've followed various threads concerning Snow Leopard and its incompatibility with the Canon MX860 printer/scanner. I have now downloaded the latest printer driver from Canon and the printer functions seem to work normally now on my wireless network.
    I have some connectivity with the scanner, but the only way I can get it to scan is by going through System Preferences - if I try going via the "Canon Solution Menu" I get the error message "Cannot communicate with the scanner". Also, on the MX860's display panel the only option shown is the USB connection - it doesn't offer any PCs so, I guess, it's not finding my wireless network, even though the printer part of the machine is.
    Does anyone have a solution to this problem? Thanks.

    Hi,
    I am running Mac OS X Leopard version 10.5.7 on a MacBook3,1 with a wireless network using an AirPort Extreme. I was able to print wirelessly to my new Canon Pixma MX860, but my Macbook was unable to communicate with the MX860 scanner. Interestingly, though, the MX860 scanner could communicate just fine the other way with my Macbook because I was able to manually scan from the MX860 console and have scans wirelessly sent as PDFs to my Macbook.
    Here's what I did to scan wirelessly to the MX860.
    I used Easy Install from the accompanying Canon Pixma MX860 Setup CD-Rom disk *version U1.4* (purchased the MX860 on March 22, 2010) and followed all of the setup instructions in the Getting Started for Mac manual. In my case, I have a wireless LAN network with one access point, the Airport Extreme, but I would follow the instructions that are appropriate for your setup.
    I went to the Canon MX860 driver page http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDet ailTabAct&fcategoryid=334&modelid=18121 and selected the MAC OS system files from the drop-down menu.
    I downloaded:
    _*MX860 series Scanner Driver Ver. 14.11.1*_ (Mac OS X 10.3/10.4/10.5/10.6)
    mx860sosxsd14111ea8-2.dmg
    (I didn't remember this file from the Easy Install, and I was unable to select this from the Navigator EX Scan menu, so I figured there was something wrong with it)
    _*MP Navigator EX Ver. 2.1.2*_ (Mac OS X 10.2/10.3/10.4/10.5/10.6)
    mpnexosx212ea8-2.dmg
    (The version that came with the CD-Rom was an older version, 2.1.0, I think)
    I installed both the Scanner Driver and the updated MP Navigator EX. The computer restarted after installing each program, so there were two restarts.
    I opened the Solution Menu from the dock, chose Scan/Import Photos or Documents from the menu, and the Solution Menu opened MP Navigator EX (now version 2.1.2). From the MP Navigator Ex menu, I chose Scan/Import Photos/Documents (Platen), selected the Document Type, and voila, perfect wireless platen scans. When I checked the "Use the Scanner Driver" box, the Scanner Driver brought up more detailed scanning options. I was also able to scan a stack of documents using the ADF.
    I know that this is a Snow Leopard thread, but I came across this thread when I did a search on exactly the same problem, so I wanted to post my solution in case it helps others. I think that the solution to your problem should be similar. If the two downloads specifically mentioned above do not help, perhaps try downloading and installing all of the other most up-to-date drivers/software on the Canon 860 page until something works.
