IP connectivity bug in Snow Leopard confirmed

In order to make sure there are no disruptions on my laptop, I have created a Location 'Home' on which I set both my Ethernet and Airport settings manually to the same information.
In my setup order, I put Ethernet as the top interface, followed by Airport.
It doesn't matter that they're both connected (green) at the same time. Mac OS X uses the faster of the two, which in my case is Ethernet. It never uses both at the same time.
I do this so that when I plug into Ethernet, I get the temporary speed boost that I need from my Gigabit network in order to transfer certain files, and then when I unplug, I fall back onto my Airport interface. Since they are both set to the same IP info, there is never any disruption on my machine.
UNTIL Snow Leopard that is...
This setup used to (and continues to) work flawlessly under Leopard. With Snow Leopard, if I unplug my ethernet cable, I see my connections to my servers drop and then reconnect. The problem with this is, if you already mounted some shared drives while you were connected via Ethernet, and then unplugged the cable to fall onto Airport, Mac OS X will stall with the spinning beach ball almost every few seconds. This is because it is probably trying to establish some sort of connection with the mounted shares using Ethernet, but since you're not connected via Ethernet, you have to wait until it times out and connects via Airport. Maddening.
The only fix for this is to eject any shares and reconnect to them via the wireless connection.
Please Apple, fix this ASAP.
Anyone else seeing this?

While very interesting, this is a forum for Snow Leopard Server, not regular client SL. So I don't think you'll get much response here.
Cool stuff, though.

  • Bug in Snow Leopard Address Book

    Apple had an incredible feature in Leopard's Address Book which is now MISSING in Snow Leopard's Address Book. This must be a bug, since it seems unlikely that Apple would choose to remove this.
    Let's say you have 15 contacts named "Michael" in your Address Book, and you lookup one of them all the time in your Address Book.. that is your most frequently called "Michael".
    In Leopard's Address Book, it would REMEMBER the most recent contacts that you looked up for any search criteria, so as soon as you started typing "Michael", it would take you right to your most-recently-looked-up "Michael"!
    But in Snow Leopard, you are out of luck!
    Whenever you type in the name "Michael", Snow Leopard's Address Book ALWAYS takes you to the very first "Michael" card alphabeitcally, so you then have to MANUALLY choose the "Michael" you want to see.
    What used to be so convenient in Leopard is now much more of a hassle and a pain!

    Scott,
    This may not be changed in my experience, but Mail 4.x must likely relearn this -- at least this is how I am finding it to work with auto-complete. I seldom actually look up in AB, but just start typing, so I have not had a chance to establish any real frequency of lookup in AB. I expect it will work similarly, but then I have not used enough to confirm.

  • Canon MP640 - "No scanner selected" bug in Snow Leopard

    Hi!
    I use a Canon MP640 printer/scanner combo unit WITHOUT installing any software from Canon. I like to stick with the built-in functionality of Mac OS X. Which means scanning via Preview.app or ImageCapture.app.
    Until recently everything worked flawlessly. Have not used the scanner in a while though and now with 10.6.4 installed I found out, that the scanner does not appear anymore in the Preview.app menu FILE > IMPORT FROM SCANNER > ...
    Opening up SystemPreferences.app in order to delete and add the printer again only helped for one scan when the scan was invoked with the printer button. Turning the printer off/on and the link between the computer to the scanner was broken again
    In SystemPreferences.app Snow Leopard says "No scanner selected" when I choose the printer and click the SCAN tab in the printer/scanner section.
    Anybody found out how to fix this issue without installing all the Canon printing/scanning software? I would like to stick with the built-in Preview.app.
    Thanks

    Sorry to read that nothing has helped to date.
    Checking the operation of my MP980 connected via USB and using Image Capture or Preview to scan, the process 'Canon IJScanner1' is the only process that starts when the scan is initiated from either application. And long after the scanning has completed and the relevant applications have been closed the process remains in the process list.
    If I force quit the 'Canon IJScanner1' process I then find that the MP980 is not listed in the 'Import from Scanner' menu within Preview. And with this process still closed, if I go to Print & Fax and click on Open Scanner under the Scan button of the MP980, the Canon MP980 scanner queue will appear but with 'No scanner selected' inside the pane.
    So I can recreate what you are seeing. But the question is why is your 'Canon IJScanner1' process stopping. If you check your Console log messages, is there any reference to this process stopping or failing?
    Checking my log it showed as follows when I force quit the process.
    13/09/10 4:34:00 PM com.apple.launchd.peruser.501 (183) ({0x0-0x577577}.jp.co.canon.ijscanner1.scanner.ica{66850}) Exited: Killed
    Also, FYI, trying to start the process again manually is proving difficult. Double-clicking on the 'Canon IJScanner1' icon in /Library/Image Capture/Devices starts the service temporarily but then stops soon after. This is shown in Console as follows;
    13/09/10 4:42:51 PM {0x0-0x61d61d}.com.twainds.mp980.scangear140800.canon{67810} /Library/Image Capture/TWAIN Data Sources/Canon MP980 series.ds/Contents/MacOS/Canon MP980 series: /Library/Image Capture/TWAIN Data Sources/Canon MP980 series.ds/Contents/MacOS/Canon MP980 series: cannot execute binary file

    The only solution I could find was to restart the Mac but this made the process re-appear in the process list and consequently I was able to scan from Preview again.

  • File:Place Function Bug in Snow Leopard (CS4)

    Hi all. Have any of you experienced this bug when running Mac OS 10.6.7 (Snow Leopard)...the File:Place function no longer works for text.  I can place graphics/photos, but when I try to place text nothing happens.  Any thoughts about this?  I'm using InDesign CS4.
    Thanks!

    I'm a Windows guy, so I'm shooting in the dark at this point. Happens in all files? How about in a new user account?
    What has changed recently ont he system? New fonts? Any software updates?
    Do you run a font manager?

  • Bugs in Snow Leopard for visually impaired users

    I'm new to Mac (MBP 17 inch 2011 model) coming to Mac for first time from Windows.  I am VERY impresseed with the accessibility options that are built into the OS.  However, I ahve found a few bugs that I feel should be addresed in the next release:
    1.  With magnifcation on, the screen will no scroll at all when the application switcher (pressing the Apple+TAB, i.e. ALT+TAB in Windows).  This makes it absolutely impossible to see which appplications are open and which one currently has the focus.  If VoiceOver is enables, it will speak it to you, but you can't scroll the screen to see for yourself.
    2.  In Safari, with maginfication on, if you try to scroll down a page (i.e. the two-finger scroll), you will IMMEDIATELY be taken back to the top of the page.  This makes it absolutely impossible to scroll down a page with magnifier on.  I really want to use Safari because of its tight integration with VoiceOver (you can highlight text, right click, select speach, and it will read it for you).  But, I really need the ability to scroll.  I use bother Magnifier and VoiceOver.  Firefox doesn't have this problem with scrolling, but it doesn't integrate with VoiceOver.
    I'll report more issues related to visually impaired users as I become more familiar with mac and Snow Leopard.  But, I will have to say that I am EXTREMELY impressed with the accessibility options already built into the OS.  In Windows, I would have to pay over $1K extra to get JAWS or $700 for ZoomText, both of which can bring Windows to its knees.

  • SQL Developer Not Connecting After Mac Snow Leopard 10.6.3 Update

    I installed Oracle 10g on a MacBook Pro running Snow Leopard 10.6.2 as described in here . All worked fine until after updating Snow Leopard last night with to 10.6.3. First I started getting an Insecure Startup Item Disabled message which I solved with the reply to my message at the Apple forums here . That took care of the first issue but now when attempting to connect with SQL Developer, I receive several errors messages in the log most of which point to the source o.jdevimpl.db.adapter.DefaultContextWrapper with a message starting with "Failed to create naming Context for db connections at url: file:/Users... I assume this is some sort of Jave error perhaps related to the Snow Leopard upgrade. However, I have absolutely no clue how to deal with it. I'm a student taking my first database class so the install of Oracle pushed me to my system knowledge limits.
    Any help would be appreciated!!

    After some poking around on a several forums, I found a suggestion to reapply the OS X update by using the combo install package. That seemed to do the trick. I can now see and connect to my DB.

  • Add bookmark button and horizontal scroll bar - bugs on Snow Leopard

    Safari after update to 5.1.4, has a bug in interface on Snow Leopard (10.6.8): 'add bookmark' button (combined with addres bar), and horizontal scroll bar didn't look good.  I think, that shouldn't happend on flagship Apple browser, on just a little older OS X than 'Lion'.
    Clearing (deleting files) 'Cache.db' and .plist files didn't help.

    Ok..  maybe corrupted Safari preferences  (.plist )
    Quit Safari.
    Go to ~/Library/Preferences
    Move the com.apple.Safari.plist file from the Preferences folder to the Desktop.
    Relaunch Safari. If that helped, move the .plist file to the Trash.
    If not, move it back to the Preferences folder.
    If that didn't help, go to Safari > Preferences then select the Extensions tab. If you have any installed, turn that OFF, quit then relaunch Safari to test.
    If it's not a plugin, try troubleshooting Safari third party unsupported add ons >  Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues

  • Why did wifi connect faster on Snow Leopard than any Lion?

    This has bothered me since upgrading to Lion and then hoping Mountain Lion would fix it.
    When I open the lid on the air (or any macbook) it takes about 10 seconds for wireless to connect. If I take any of the same computers (macbook pro from 2010, air 2011, air 2012, macbook pro 2012) and install Snow Leopard on them, when I lift the lid from sleep, wireless is nearly instantly available.
    I work in an IT department in an academic library so I have access to a lot of machines. So I've been trying this a lot lately since the computers I deploy to the public are now all on Snow Leopard after receiving many complaints about the wireless connections.
    Granted I live with it on my machine, 10 seconds is plenty fast. But I find it annoying, it's like a step backwards. It used to be fast, now it is slow. I don't find the wait to be acceptable given that Apple proved in older operating systems that near instant wireless was possible.
    Is there some way to alter the settings to make wifi connect quicker? I've done all the obvious, my mac address is registered with the networks, my preferred network is the only one in the list, I use a static IP. I guess what I want is for the wifi to never sleep, this is what Dell does on their XPS machines which ironically was designed from a group that used macbook airs running snow leopard in an effort to make wireless instantly avaialble for windows/linux.

    I just performed another test. Two identical (serial numbers 1 apart) iMac. These are units I release for public use in a kiosk mode. They are scheduled to sleep during the hours the library is closed. I deployed one with snow leopard and one with mountain lion last week, so far I've received 6 reports that the mountain lion machine can't connect to the internet but when someone assists, it connects. I'm guessing that they walked up, clicked a link and it didn't respond so they asked for help and when the person walked over (takes about 20 seconds to walk to/from the help desk) the machine connected.
    Both machines have identical network settings and use wireless where the WAP is literally 6 feet above the machines. So this morning I upgraded the snow leopard machine to mountain lion, and added a third snow leopard machine to the space. I suspect I will start getting complaints on the two lions but never on the leopard.

  • Mac-Windows-Connection failes after Snow Leopard Installation

    I am dealing with 4 PCs at home – an IMac, a MacBookPro, a Dell Dimension and a Dell Precision Workstation. Before I installed Snow Leopard I could connect easily from my Macs to my PC via “Connect with Server” and the “sudo pico /etc/hosts” hint to rename my Windows-PC to real names (e.g. Dimension and Precision). After the installation I am prompted in OS X to give my account name and password again! And, of course, I don’t work anymore (wrong user name or password error). Because I put those information in long ago, I am not quite sure if I am putting the wrong Name/Password info in or if something happened during the Snow Leopard installation. I was never quite sure if “Name” meant the name of my Windows account I want to log into, or my Mac user name or a combination of both or the Server /Name thing, e.g. Dimension\Name. Just for info: My Windows-PCs can still connect without a problem to both Macs.
    Any help is appreciated what information exactly to put in that **** Name/Password box that appears if I want to connect to a Windows-PC from my Mac. Or what else could have happened during the Snow Leopard installation that cut of the former available ability to connect to my Windows-PC from OS X.

    I was able to see the other Windows XP computer and begin to connect. I was then presented with a login screen. I tried using the usual user name and password - no luck. I then formatted the user name as as follows:
    user name: computer name\user name
    password: as normal
    And it worked. Specifically in my case:
    user: cwy-pln2152\administrator
    password: planning
    This is what worked for me your mileage may vary.

  • Lost wireless connection after installing Snow Leopard combo update.

    Hi everybody. I installed Snow Leopard on my father-in-law's Mac Mini (one year old) over Christmas, as a gift. The upgrade went fine. Everything worked until I performed a SW update. It downloaded a mammoth 500+ MB combo update (wirelessly), installed it, and boom. No wireless.
    His network has no security; it is open. The Mac could see/find the network, but timed-out when connecting. Connection Doctor and Network Diagnostics; all red lights. His Dell and my iPod Touch had no problem connecting. I tried switching user accounts, turning Airport ON/OFF, trashing Locations and using Automatic, inactivating interfaces, disabling firewall, restarting, PRAM reset, and probably some other things I can't recall.
    I couldn't leave him without any Internet, and I didn't have a patch cable to try, so I restored him to 10.5 using Time Machine. His wireless went back to normal and is working fine. So he has my Christmas gift, but he can't use it.
    I have seen some related experiences in this forum, but not quite the same. Anything I try will now need to be done remotely over iChat Screen Sharing, as he is 190 miles away. Thank you for any assistance.

    Problem Solved..sort of. I was able to restore full connectivity by disabling the WEP encryption of the WIFI. This is very strange to me, prior to getting the ATV, WIFI was only rurned on for brief periods to allow my laptop to connect or when using a Sondigo wireless music bridge (great product BTW.) After enabling WEP I had no problems in connecting either the ATV or the Sondigo unit to the WIFI, there was however a problem with my laptop in that it showed a very solid connect to the WEP enabled network but I could not browse the internet. FWIW my router is a Linksys WRT54GX. Hopes this helps someone else

  • MacBook HDMI connection problem after Snow Leopard Update

    I recently upgraded my MacBook to Snow Leopard and discovered my HDMI set up no longer works after the upgrade. It has worked for the past two years with Leopard without any problems.  Now when I plug in my HDMI the computer recognizes that the TV is there but only shows up black on the TV.  Checked the display settings and is set on "Mirror" still.  Everything is the same except the OS upgrade.  Has anyone had this problem and found a way to fix it? Any suggestions?
    Thank you.

    Hi Guys
    I've read through a lot of the forums on this subject and it seems the problem has been going on since pretty much the start of Snow Leopard being introduced.
    One of the questions I've seen is: will buying a new battery solve the problem?, The entry from BeetleMegaFan on the below forum may offer some advice to this question, it would seem apparently not.
    http://forums.cnet.com/7723-21565_102-357366.html
    Another thing I tried is removing the com.apple.PowerManagement preference which at least seemed to allow the MacBook to see my battery long enough to take some screengrabs of the System Profiler (could be one of the random co-incidences).
    Just to check/prove this is "potentially" a Snow Leopard problem I booted up from my original 10.5 system discs and guess what, no problems.
    I also got a new one yesterday: Battery not charging, the joy continues but at least it knew there was a battery in there!
    Would really appreciate an answer or advice on this one but I'm fast thinking there isn't a solution available at present.

  • Ipad 4 connecting to a snow leopard Imac?

    I just got an Ipad 4, I am running snow leopard on both of my computers, when I plug my Ipad into my computer it says I need the newest version of Itunes, but the newest version of Itunes requires that I have at least lion OS. Anyone have any suggestions? All I want to do is drag some PDF's from my computer to my Ipad, so far I have been emailing them to myself, but they are all at least 10mb each and I want to get about 150 to my ipad.

    OK. I thought that your response seemed odd to me. Makes sense now.
    You can try this - but its not an "out of the box solution". Apps like GoodReader (from what I have read anyway) will work with iCloud. You could install GoodReader on the iPad, set up iCloud on the iPad and then go to your iCloud.com account on your Mac and drag the PDF files into the browser window and the off files should appear in GoodReader on the iPad.
    I can tell you that you can access iCloud.com from a Mac running Tiger 10.4.11 because I do it here in my office. It's not an ideal solution, but it would probably work. There are aspects of iCloud that work with lesser OS X versions on a Mac and this is one way that it does work.

    Yes, we have a handful of bugs filed with Apple about similar issues introduced in MacOS 10.6.
    We're all waiting for Apple to release the fixes.

  • Connecting to MAC (Snow Leopard) from Windows 7 PC

    Been trying to get the iMac to connect with a windows 7 pc. Have successfully connected to the PC from the iMac using the Go/Connect to server method. From the windows 7 PC perspective, the iMac shows up in network neighborhood, but when I double click on the iMac get an error message - "Windows cannot access ..." then the name of the iMac. This is associated with error code 0x80070035.
    From the windows 7 PC, I can successfully ping the iMac by name and IP address. The iMac and PC are using the same workgroup name as well. I'm thinking the problem is associated with how I configured sharing on the iMac --- but I can't seem to figure out the problem. This is how the iMac sharing is configured:
    - have a public folder set as the shared folder, with everyone identified as having read and write privileges
    - under sharing/options,"share files and folders using SMB (Windows) is selected
    - below that, have the "on" button checked for the accounts I have on the iMac.
    Thinking that there is something in the sharing configuration that is the problem. Would appreciate any help. Thanks.

    I don't know a whole lot about this topic, but I do know that, in Vista, Microsoft apparently disabled some important feature required for connecting to a Mac for file sharing, which caused some problems for my wife. We finally solved the problem for her by doing the following:
    Go to the Start menu and go to All Programs -> Accessories -> Run
    Type "Regedit.exe" and press return
    Go to HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    Select Lsa, then choose Edit -> New -> Key
    Type "DWORD" (without quotes) as the name in the list
    Double-click the text "(Default)" in the right-hand pane
    Enter "1" (without quotes) as the value and press OK
    Quit Regedit and restart the machine
    Log in to the remote Mac using "ip_address\username" as the user name
    I'm not sure if this is still relevant on Windows 7, and I recall there was a much easier solution if you had one of the higher-end versions of Vista... but my wife only had Home Premium, which meant she didn't have the tool needed to make this fix easy. Stupid Microsoft...
