  • Is it true MS Office doesn't work with Lion?

    I just purchased OSX Lion and while it was downloading I began to read the reviews.  I saw multiple comments that MS Office doesn't work with Lion.  I forced a shutdown on my MacBook Pro because I couldn't see any other way to stop the LIon download.  Now with it back on, the download is paused.  I don't want to resume it until I find out if it's true about office.  Any help?

    Len , MS2008 does require Rosetta. Ms2011 does not.
    W7ox, I tried 2 different licenses. I have 12 licenses here on site. I resorted to reading it straight off the box and still no joy. Very strange!
    Incidently. I can not access the Snow leopard Server either via the normal 'Go' and 'connect to Server'.
    Have tried afp and SMB. no joy.
    I am wondering if the ethernet Dinlge adpater to the Rj45 connector has any hardware issues?? will keep expeirmenting and any feedback appreciated, as I am NOT going ahead with any Lion updates on 12 macs until I know more about its bugs! ciao

  • I have 3 macs. 2 are Lion, 1 I left Snow leopard so I can access data from my old Quicken Application that doesn't work with Lion. If I move to iCloud, will I no longer be able to access my MobileMe email on the Snow Leopard mac?

    What version of word do you have? The TS3938 sounds like it's a PowerPC app- written for an old architecture that is no longer supported in Lion. If this is the case, your files are fine- you just need a newer version of word that will run in Lion in order to open them. The newest version (2011) should be readily available anywhere, and has worked fine for me ever since I switched to Lion on release day....

  • My SuperDrive doesn't work after Lion update

    My Superdrive doesn't work after Lion update, i have tried a few solutions that i found in forums, but nothing seems to work, please help me shed some light on my problem.
    Thanks

    I too have had the problem since updating to Lion.  My superdrive isn't even recognized.  I have repaid hard disk permissions and also reset PRAM.  Sure wish I had a fix. 

  • The 7 key doesn't work after lion install

    The 7 key on my MacBook pro keyboard doesn't work following lion installation. (I'm using my iPad right now obviously!)
    When I press 7, basically random stuff will come out. A set of 3 to 5 random numbers or some "command" that whatever program I am in doesn't recognize. 
    I tried rebooting. I have no idea where to even begin, help!

    And of course this morning all keys are back to working again! But last night it was 7, J, U gibberish.
    At first glance it does seem like something that might be a hardware problem, but I am deeply suspicious of coincidences like this. I'm kind of like house md that way I guess.  Especially when at least two of us experienced this.
    I think I will also wait for the next software update and see if that helps.  At least I have my iPad to use when the keys are on the fritz.
    Good luck!

  • Ctrl + numbers switch between spaces doesn't work in lion

    After a fresh install of Lion I'veexperienced strange behavior in mission control. I copied all my apps,documents, settings, etc. from SL to Lion but I noticed something different in Lion. Before I changed spaces by using ctrl+number-keys but for some reasonthis doesn’t work in Lion for me. It does nothing. When I hold down ctrl anduse the arrow-key it scrolls to the next space with a smooth animation. Afterthis and still holding the ctrl-key and pressing a number-key (3 for instance)it does jump to that space with a faster animation. But after releasing thectrl-key and trying it again without any arrow keys involved it doesn’t work atall. Is there anyone hew is experiencing the same problem? Anyone with a possibleexplanation or a way to solve this issue? I’m wondering if this has somethingto do with the clean install because my father did an upgrade from SL to Lionand ctrl+number-keys to switch between spaces works fine for him.
    Thanks in advance,

    Go to the Keyboard preference pane -> Keyboard Shortcuts -> Mission Control and check to see if you have the ^ + number keys set.

  • Apple Modem (for dialup) doesn't work in Lion. Why?

    We have no acceptable alternatives for dialup where I live here. Even dialup is difficult. But the Apple Modem does not work in Lion!
    Anyone know why Apple did that?
    And what alternative is there for us (other than resinstalling Snow Leopard).
    Does Apple not know that there are still PLENTY of places with poor or non-existent Internet services?
    Does anyone know of an option?
    Using a MacBookPro, but the problem appears to be Lion so the hardware would not seem to matter...

  • Keynot does not work with Lion OSX 10.7.2

    First there was the problem with the hidden Library/application Support/iWeb/domaines, which is an important problem for me as I use my web site to show people what kind of work that I do (videos with still photography); now there's the problem with Keynote, which does not even open with Lion OSX 10.7.2. Up until now, I was using Keynote to do my video projections in small town halls. I use Protools for the sound and Final Cut (that's another problem!) for the photos and then do a Quick Time session which I put in Keynote. It was working just fine - until Lion came along.
    It seems to be well known that Apple is going to discontinue iWeb (let's not talk about what they did to Final Cut) - and now it looks like they've got plans for Keynote as well. It looks like the solution is either to use PowerPoint rather than Keynote, or to downgrade back to Snow Leopard. I'm tempted to change to PowerPoint just to keep in the race, but where is Apple taking us? I'm not sure that what Apple want's us to do is really good for us! But is it realistic to hang on to Snow Leopard? Are the PCs better or are they doing the same thing? It almost seems as if there were commercial agreements between those who run everything...but that's another story - or is it?

    Yes, it should work with Lion.  It does for lots of folks.
    Are you getting an error message of some sort?  If so, see #C2 in Time Machine - Troubleshooting.
    If that doesn't help, try re-selecting it, via Time Machine preferences.
    Or try a "full reset" of Time Machine, per #A4 in the Troubleshooting article.
    Or reset the TC itself, per http://support.apple.com/kb/ht3728

    No reason it should have stopped working. Maybe a problem waiting to happen and an upgrade pushed it over the edge. Provide some specs on your Mac, but I would really advise making an appointment at the Genius Bar at your local Apple Store.
    Good Luck

  • CS4 doesn't work after LION installation

    After the Lion installation i had several problems.
    One of these is that the cs4 doesn't work.
    i open illustrator or photoshop and they crash every time. "photoshop not responding" "illustrator not responding" and so on..
    I had to reinstall all the suite that now works.
    The question is... why??
    I thought is is better to format the mac... should i do ?
    thanks

    Another problem is:
    When I start the Dropbox Application, it uses nearly 90% of the CPU as well, so the mac heats up, in a way that it is not possible to use the dropbox application...
    (The Icon of the VLC Media Player  only jumps up and down in the dock, and nothing else happens)

  • Cisco VPN not working with Lion OSX 10.7

    Cisco VPN Client Application did not launch after upgrading to Lion OSX v10.7. 
    I read https://discussions.apple.com/thread/3192535 that suggested rebooting in with a 32bit kernal.
    Hold down the '3' and the '2' keys while rebooting to reboot in 32bit mode.
    I did this and now my existing Cisco VPN works fine.

    Cisco VPN Client & OSX Lion
    I have been successfully using the built in Mac OS X IPSec client on Lion 10.7.2 for a couple months now. I have no need for the Cisco IPSec client anymore and to boot into stupid 32-bit mode .
    Not sure if the issues you guys are having but I followed this guide and it works perfectly. Most of my customers I only have a .pcf file for, which of course, I cannot use to figure out the groupname and password....until now...

  • Wireless suddenly doesn't work, both in OSX and windows 7

    I have got a new model of MacBook Pro 13-inch. Everything work fine until one day I found the wireless suddenly didn't work, both in OSX and windows 7(boot camp.)
    I tried my USB-wireless adapter on macbook, it works fine.
    In bootcamped windows 7, I have uninstalled and re-install the wireless adapter, still doesn't work.
    Actually it can find the wireless networks but cannot join them.
    I need to mention before then I kept play heavy games like starcraft2 frequently, and macbook got so hot during playing, so maybe the wireless module was damaged by heat somehow??

    Seems I'm pretty annoying but I need to post again because I found something interesting: once I plug my external monitor to the macbook, the wireless strikes, and once I plug out the monitor, wireless recovers... Anyone has any idea?

  • USB Headset doesn't work on Mac OSX but does on my WinXP Bootcamp partition

    Hi all,
    I bought my FIRST Mac 2 days ago and am very excited about the migration. My reality is that I need WinXP for work-related activities and so I successfully installed Bootcamp and both WinXP and Mac OSX is working fine.
    My problem is with a brand new Logitech USB Stereo Headset 250. It works just fine on the Windows XP side, but I can't get it to work on the Mac OSX side. Is there something I should be 'turning on' to get the headset to work? Like I said, it just 'worked' when I started up with the WinXP partition but when I restarted in the Mac OSX partition, it doesn't work.
    Apologies if this is a simple thing that the veteran Mac crowd is snickering at as they read this, but I truly want to use the Mac OS as much as possible and if I can't get the headset to work on the Mac side it won't be a good thing.
    Any suggestions?

    Got it (sorry all) - I went into the System Preferences and selected the USB headset from the 'output' tab.

  • Front Row doesn't work properly in OSX 10.5

    I'm having a problem with Front Row not working properly in OSX 10.5
    iPhoto transitions aren't working properly in the slide shows, My monitor keeps turning off,
    I have a KDS 17" LCD monitor.
    Also iMovie will show movies with big blank gaps in the video,
    Yet iPhoto and iMovie will run fine using OSX 10.4.10
    The other iApps of iLife 08 appear to be alright so far.
    Is there a fix coming?
    Dave

    Figured it out...
    The "Front Row" settings were set for a screensaver, That's why the monitor kept blanking out,
    I've turned off the screensaver in the settings and "Front Row" works fine now.
    There is no screensaver image chosen, That's why the screen kept going blank or even off.
    Hope this helps others.
