Any problems with lion running on core 2 duo 2007 MBPro ?

Curious to hear if anyone has had any problems with Lion before I upgrade.
Thanks.

OK, so this is a shot in the dark, but maybe it's worth a try.
Since the problem only occurs when running on battery, perhaps changing the Energy Saver settings to match the settings used for when it's plugged in will fix the problem. The default settings for how the computer operates are different for the battery and power adaptor. When you unplug the power, the computer automatically shifts to the alternate settings.
So, try this:
-Open System Preferences->Energy Saver
-In the "Settings for" drop-down menu, select "Battery".
-In the "Optimization" drop-down menu, select "Better Performance".
-Under the Sleep tab, choose "Never" for both computer and display sleep and uncheck the box for "Put the hard disk to sleep when possible".
-Under the Options tab, uncheck the first two boxes.

  • Are there any problems with Lion and Adobe CS5 ?

    I am wanting to upgrade to Lion but don't want to have the hassle of trying to fix any problems as I have heard some people had problems with earlier versions of Adobe Creative Suit and Lion and having recently moved I have no clue where my CS5 keys are so before doing so I want to know there will be no errors.
       Peoples experiences would be appreciated and many thanks.

    I have upgraded two Mac mini's which both have the Adobe Creative Suit Cs5 Acrobat, Illustrator, InDesign and Photoshop. I have had no issues regrding the upgrade, they just work.
    However I do have two user interface issues. InDesign the keyboard page up, page down keys no longer work as expected, they simply jump to the next screen, the workaround is to use a trackpad for the left hand and use two finger scrolling.
    The other is the arrow buttons in the vertical scroll bar no longer exist, so again the trackpad comes in for scrolling.
    This applies for almost all software and the finder.

  • Power and battery problems with MacBook Pro intel core duo

    Hi there, I've been having this problem for about a week now with my macbook pro where it shuts down a second after it's unplugged, even though the battery is full. I tested the power cord with another that works, and the same thing still happens. I've zapped the p-ram, and reset the MPU where you take out the battery and hold down the power button for 5 seconds and all that. I think it might be the logic board, or something within that? Any suggestions before I send it in to Apple for investigations?

    I started having the same problem several days ago. Unplug the magsafe connector, and the MBP powers suddenly powers off, even though the battery shows a full charge on both the menu bar and the battery leds.
    I decided to try a new battery after reading a number of posts here about the same problem.
    Back to normal with the new battery. So now I'll go back to Apple to get the non-functioning battery replaced under AppleCare. (I wanted a second battery anyways)
    Hope this helps.

    You need a "Core 2 Duo" for lion, and I'm guessing you only have a "Core Duo"  My wife's macbook is also a "Core Duo" and has Snow Leapord, but cannot install Lion.....

  • My Macbook Pro with 2.16GHz Intel Core Duo (Mac OS X v10.4 Tiger) can convert to Lion?

    my Macbook Pro with 2.16GHz Intel Core Duo (Mac OS X v10.4 Tiger) can convert to Lion?
    Toyoo

    These are some of the most common Questions (Q) and Answers (A) about Lion:
    Q: What are the system requirements of the Lion upgrade?
    A: Core2Duo, Core i3, i5, i7, and Xeon Intel CPUs with 2 GB of RAM in a Macintosh computer with 2 GB of RAM, and 4 GB (7 GB after installed) for downloading from the Mac App Store (Available in 10.6.6 and later). Unofficially, past upgrades have arbitrarily also required an additional 15% of the hard drive to be free for data.
    Q: What applications are compatible with Lion?
    A: http://roaringapps.com/apps:table provides a nice third party editable listing for people to include the compatible applications. Many of these compatibility entries came from before Lion's release. Please verify they are correct now that it has been released, and help edit it for more accurate data. Be sure to include any update version of Lion post release that you have found is or is not compatible with it, for the help of others who may be upgrading to Lion the first time. Additionally, as it was released, there is no Rosetta. This means any application that is stated to be PowerPC in the System Profiler, will not work with Lion, and needs a comparable application or upgrade to be compatible. The System Profiler is in Apple menu -> About This Mac -> More Info. Intel and Universal applications are on the whole supported, though may still need some tweaking before every feature is compatible.
    Q: Are there any pitfalls to watch out for?
    A: With all upgrades, backing up your data at least twice has been a given. Hardware can fail independently of downloads and upgrades, though may happen simultaneously. Software may be found to be incompatible that has not been tested with the new upgrade, or combination of other software that might be installed with the upgrade. It is also strongly recommended once your backup is complete, to shut down your computer, remove all but Apple wired keyboard and mouse (notebooks remove all input devices). Then once done, reboot, and go directly to the upgrade distribution system available. Third party system tools, modification, and "maintenance" applications should be verified as compatible, or removed until known to be compatible. Check with developers how to remove if it is essential to use Lion before those applications become compatible. Most "maintenance" tools that deal with system cache, prebinding, are not really maintenance tools. Ask on forum when are the appropriate times to use them before assuming they should be used for upgrades or otherwise.
    Q: How can I get from 10.4 or 10.5 to 10.6.6?
    A: Purchase a 10.6 retail installer from an Apple retail or third party reseller. It has a picture of a Snow Leopard on the DVD, and does not say Upgrade, Dropin, or OEM. Install it, and then install the 10.6.6 combo update from:
    http://support.apple.com/kb/DL1349
    Q: Is it true that I can only get it from the Mac App Store?
    A: Presently this truth is based on current documentation as of the writing of this article. It may change, but we can't speculate as to its change. It has a better chance of changing if users request something different at:
    http://www.apple.com/feedback/macosx.html
    Q: What limitations might one encounter if it doesn't change?
    A: First off the 7 GB space limitation on the hard disc after it is installed. Secondly, the size of the download file requires significant time, unless you have a high speed broadband connection. Times expected are below -
    4 GB at:
    5Mbps is 2 hours.
    at 1 Mbps is 10 hours.
    at 384 kbps is 27 hours.
    at 56k kbps is 184 hours (nearly 8 days).
    If you include the 10.6.6 combo update of 1.06 GB
    add 29 minutes for 5 Mbps
    145 minutes (2 and 25 minutes) for 1 Mbps
    6 and a half hours for 384kbps
    A 24 hour day and 15 hours (for a total of a minimum of 39 hours) for 56kbps
    Remember the retail 10.6 currently does not include the App Store, and those upgrading from 10.5.8 or earlier will need to both buy the retail 10.6, and download the combo 10.6.6 update, not to mention ensure they have the correct processor and 2 GB of RAM. Finally once it is available, you'll have find out how long approximately it takes to install after the download is complete.
    These times do not include installation time, which on a MacBook Pro 3,1 15" installing on a Firewire 800 Newertech Voyager with WD10ACS-322J80 drive, 10.6.7, took 1 hour and a half to complete the installation from double clicking the install command to the registration screen. These times may vary by connection speeds from a non-dedicated connection, or background application usage of the internet. Any applications running when the installation process begins might interfere with the installation itself, and they should be quit first.
    The installer just before it starts has in its package contents an InstallESD.dmg file a DVD burnable image to install on additional computers in the home without downloading over again. So if you desire to reinstall without an extra internet download, extract that file, by selecting the installer in the dock, and control-clicking it, and revealing it in the Finder. Next Control-mouse click it, and select show package contents. Inside that folder is a Shared Support folder. That's where you find the DMG.
    Q: If I purchased a Mac recently, can I get it cheaper?
    A: Yes, visit http://www.apple.com/macosx/uptodate/ for details.
    Q: When will Lion become available?
    A: It became available July 20, 2011.
    Q: Which Macs can run Lion?
    A: Look at Apple menu -> About This Mac -> More Info, and see if you meet the Machine ID and RAM requires under the hardware. 2 GB is required for all These Machine IDs will run Lion:
    Mac Mini 2,1 and later
    MacBook 2,1 and later.
    iMac 5,1 and later.
    All MacBook Air.
    MacBook Pro 2,1 and later
    All MacPros.
    The Macs with the Machine IDs below will not run Lion (x can be any number):
    Mac Mini 1,x or PowerMac x,x
    MacBook 1,x
    MacBook Pro 1,x
    iMac 4,x, 3,x, 2,x, 1,x

  • Anyone provide accurate info on why after 1 yr, after guarantee period expiry the DVD player on our I mac running Intel core duo processor with OS 10.6.8 refuses to run DVDs? CDs run

    Can anyone provide accurate info on why after 1 yr, ( just after guarantee period expiry) the DVD player on our I mac running Intel core duo processor with OS 10.6.8 refuses to run DVDs?
    CDs run without problem and until recently the DVD we have (all original no pirated copies) ran; we have used a CD cleaner disc to no avail.

    Welcome to the Apple boards:
    I suggest an erase and install and use your backup for any important files you have.
    Did you perform a disk check/repair and permissions repair and a PRAM zap before updating? While not required, they are usually necessary to avoid issues.
    There are so many reasons for a bad install, that it is impossible to list them all.
    Out-of-date software, drivers, etc, haxies, and other software can cause problems.
    My three updates were without incident, so it is possible for a perfect update, but unless you supply us with details about your previous system, programs, apps, drivers, etc., it is not possible to figure out what happened.
    Again, whenever installing an update to an OS, a clone or other full backup is absolutely necessary, as reading the posts on this board indicate.

  • ICloud on older Mac running 10.6.8 - with Intel 2 GHz Core Duo

    Do I understand correctly that I can't upgrade to iCloud from Mobile Me, with an older Mac running 10.6.8 (with 2 GHz Intel Core Duo)?

    This will be the situation with Snow Leopard if you migrate your MobileMe account:
    Your email, calendars, contacts and bookmarks, and 'Find my iPhone' will be migrated to iCloud.
    Your iDisk, together with website hosting and Gallery, will continue to work as before until next June.
    Syncing of Dashboard Widgets, Dock Items and Keychains between Macs, and Mail Accounts, Mail Rules, System Preferences, Signatures & Smart Mailboxes between Macs & iOS devices, will cease altogether.
    You will be able to access email, calendar and contacts on the iCloud website at http://icloud.com provided your browser is reasonably up-to-date.
    You will not be able to sync contacts or bookmarks from a pre-Lion Mac.
    You will be able to enter the server settings for email manually in the Mail application and access your email.
    You will not be able to sync your calendars directly.
    Some people have been able to set up calendar syncing by using the method detailed here - this is an unsupported hack and may not be reliable, and may stop working at some future point. BusyCal is an iCal-like calendar application with extra facilities: it can sync with the iCloud Calendar while running on Leopard, Snow Leopard or Lion.
    There appears to be no method of syncing contacts (though Address Book on a Mac can be synced with Google or Yahoo address books - I don't know how reliable this is).

  • My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced.

    My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced. Is it internal battery for both, new logic board required, bad hard drive, or bad RAM?
    Help.

    Run an Apple Hardware Test using the original installation disk that has the AHT instructions on it.
    Try SMC and PRAM resets:

    It is possible that you may need a new PRAM battery.

  • Is there any way to solve the wifi problem with lion?

    Since upgrading to lion my iMac has been having severe problems connecting to my wifi router. As long as it doesn't go to sleep it is fine, but if it does then I have to restart the computer to connect to the router. I know that it is lion as I've got 2 iphones, 2 ipads, and 2 laptops in the house all operating without problems. Please any help would be greatly appreciated. I tried contacting apple and they won't help me unless I pay them, or sign up for apple care. I already paid for the **** computer and the OS why would I pay them to address an issue that is clearly on their end when my computer is still under warranty?

    There's a number of things you can do to try to diagnose the problem, and hopefully it doesn't have to do with a hardware problem.
    I think the number one reason people are having problems with Lion is because most of the installations are UPGRADES, not CLEAN installs. While it's much less of a hassle for an upgrade rather than a clean install, weird and random problems can arise from an upgrade to an OS.
    Another reason is the fact that this is a dot zero release, meaning it's version 10.7.0, meaning there are bugs that have not been fixed yet.
    So the first thing you can do is to repair permissions in Disk Utility and restart your Mac. I don't think that will exactly fix the problem, but it's a step.
    When it's restarted, wait a few minutes and put it to sleep and wake it up and report back.

  • Any problem with reinstalling updates?

    Hi. I have a simple question: Is there any problem with reinstalling the OS X updates, or reinstalling the combo update? That is, I'm running 10.4.7 now. Can I (re)install the the combo update over this already updated OS X? Will this mess anything up? Is it something even worth trying when troubleshooting?
    (This is another topic altogether, but FWIW, I'm trying to track down intermittent problems I have logging in, or the system unable to launch apps or shut down.)
    20" Intel iMac Core Duo   Mac OS X (10.4.7)   1GB ram

    Hi deepermotive, Welcome to Apple Discussions.
    Yes, you can safely apply the 10.4.7 Combo Updater. It does not matter if you have applied it before. This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing.
    This may help your other issues, if not post back.

  • On my Mac Mini, I keep getting this error message: "iCloud encountered an error while trying to connect to the server".  I don't have any problems with iCloud on my laptop / PC.  It works fine... Does anyone know what the problem could be?

    Your Mac must be on Lion (10.7) to run iCloud. Apple had to change the operating system to fully support it. Nevertheless, it is possible to get emails from iCloud without having Lion. Please tell me if this interests you.
    Anyways, here is the link to buy Lion (30 dollars, totally worth the upgrade ): http://itunes.apple.com/be/app/os-x-lion/id444303913?mt=12

  • Startup problem with Lion OS 10.7.3

    Just recently, I've been experiencing a startup problem with Lion. I don't usually have any issues running my Mac, so I'm at a loss why this is happening now.
    I have an Intel Mac Pro running 10.7.3. I usually leaving my Mac running all the time and only restart when the need arises. In addition to being my main computer, this mac alsocontrols a MacMini that serves as a music server thru screen sharing.
    This past weekend, I restarted my Mac and could not get past the grey screen. The mac chimes, the apple logo appears with the spinning gear, the blue screen briefly appears, but instead of progressing to the desktop it reverts to the grey screen with a repeating cycle of the spinning gear appearing (spins for a while, stops, disappears, reppears spinning, stops, disappears, over and over) - never progressing beyond that stage.
    I decided to reinstall the system and things have been fine for the past few days. Today, restarting again resulting in the same problem.
    I've tried several things without success. I disconnected all peripherals, reset the PRAM/SMC, ran Disk Utility from a install volume and ran repair and permissions (no problems reported). Tried safe mode startup - a progress bar appeared but never fully progressed and could not get to the desktop.
    Recent changes included updating the OS to 10.7.3 and Adobe Photoshop CS5.5 - no recent hardware changes. No bluetooth devices connected.
    Any thoughts? Thanks -

    Thanks -
    I've reinstalled the OS today and am back up and running.
    But, since this is twice this has happened within the past week, I'm worried about might be causing this issue - besides bad luck. My Mac is usually rock solid - can't remember the last time I've had to reinstall the OS in the past few generations of OS X.

  • Does Lion support MS Office for Mac 2011? The RoaringApps compatibility list shows Office 2011 having some unspecified problems with Lion.

    I'm running MS Office 2011 on Lion and it runs just fine.  No "Full Screen", but it runs just fine.  There may have been an update to install (I know there was an iWork one anyway), but even before I installed any updates Office '11 worked just fine.
