Lion on old Macbook Pro?

I have an older Macbook Pro and was wondering: would it handle Lion well? Here are the specs:
Model identifier: 3,1
2.2 ghz core duo
4 MB on-chip shared L2 cache
160 GB drive with about 35 gigs free
Any help would be appreciated. Thanks!

I only had the chance to compare speeds from Tiger through Leopard to Snow Leopard (and even Lion) on a 2006 MacPro 2xDualCore 2.66GHz with 8GB RAM and can't say that I witnessed speed-changes for worse or better through the OSX versions.
But mileage can vary.
Our residential Kappy (formerly known as The Professor) has made-up a nice list of Maintenance Tips and Tricks, that I quote below:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation.  TechTool Pro 4.5.1 or higher are Intel Mac compatible;  Drive Genius is similar to TechTool Pro in terms of the various repair services provided.  Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.  These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.  Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe modebefore doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Backuplist
Carbon Copy Cloner
Data Backup
Deja Vu
iBackup
JaBack
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.

  • Can i update osx mountain lion to old macbook pro 2.6ghz

    Hi, is it possible to update my old macbook pro 2.6GHZ Core 2 Duo/2GB/256MB to mountain lion? I don't know the build/model date? Serial no.W8******02D.
    <Edited By Host>

    Probably - this is what I 'found' in MacTracker:
    ...and that's what that Apple Serial Number website pulled up for that serial number. We'll have to wait for the OP to clarify!
    Clinton
    edit: but MacTracker also says that model can use OS X Mountain Lion... so regardless of model, the answer to the OP should be "yes."

  • Lion in old MacBook Pro.

    I have a 17" MacBook Pro 5,2, Inte Core 2 Duo (late 2009).
    Im planning to install Lion but have read some threads that its not so good in old computers.
    Any advice about this?

    Plenty of advise in the More Like This  Section on the right...

  • Install lion on old macbook pro

    I'm using a MacBookPro2,1 - purchaced 2007. 17 in. OS 10.6.8. 4 GB RAM installed. It only recognizes 3.
    I use this mac professionally for graphics and web development. I also have a .Mac account and I don't want to lose the use of it by not updating to Lion. I don't care about iCloud. Probalby won't use it. An this old macbook doesn't take advantage of some of the other techy trick that come with Lion like the mouse pad functions amoung others.
    I have Lion thumb drive that I am ready to install on a couple other Macs. An iMac (late 2007) and another MBP 15.
    First. Is this a wise move updating to Lion? If I do decide to do it, should I do a clean install or install over 10.6.8? I understand the importance making a full backup and making a clone of current system.
    I assume that the preferences I may want to bring back into Lion will be compatible after a clean install as they would be if I did an update over 10.6.8. Also all the programs I'm using now such as all Adobe CS4, Parallels 6, Microsoft Office 2008, will still work.
    I've read some disappointing experiences in these communities giving some concern for the usability and stability of my Macbook.
    Some feedback from some others using their macs as I do would most appreciated.
    TIA
    YM

    As you have a Lion thumb drive you can try Lion on an external drive to see if you like it. 
    If you have a clone on an external drive you can install (upgrade) Lion on this. Then you can boot from the upgraded external Lion cloned drive and use it to see if it is satisfactory.
    I you like it you can clone the external Lion to your Mac drive.If you don't like Lion you still have 10.6 on the Mac which can be re cloned the external drive

  • I want to update to LION,on my Macbook Pro duo core, (october 2006) because Adobe CC needs at least that. I know my computer is old, but works perfect to me and I do not want to stay in Adobe CS6 since I have access to Adobe Cloud CC. Please help.

    I want to update to LION,on my Macbook Pro CORE 2 DUO, (october 2006) because Adobe CC needs at least that. I know my computer is old, but works perfect to me and I do not want to stay in Adobe CS6 since I have access to Adobe Cloud CC. Please help.
    I probably dont want to go to Mountain Lion either because I've heard that it will slow down my computer, So, Lion 10.7 will be the perfect OS X for me.
    I have ne newest release of Snow Leopard installed and works great.
    Thank you ALL for your help.

    you will be ok updating to the new software but there will be some trade off. i have 3 macbooks 2006 that are all running the latest versions.
    some of the trade off are
    1-2 less of battery life
    slow wake ups from sleep
    slower start up time about 30-40 seconds longer then what you have now
    the operating system will use high % of your processer while idealing
    these are not the things you want to hear about a new os compared to the old one but this is how it is even with a new macbook pro. but it's not the end of the world. just make sure you have at least more then 2GB of ram and have a good harddrive and you will be ok.

    I have a 2 year old macbook pro  os x 10.5.8 want to upgrade to lion

    Mountain Lion Requirements:

    Check both above first. Then call Apple Sales & have them send you a retail Snow Leopard Disk(US $29)...there is no download. Update to 10.6.8, then go to Mountain Lion or Lion if you like(US $19).
    Don't know if Apple is still selling Lion...you'll have to ask Apple sales when you call. You need Snow Leopard to get the Mac app store where you can then purchase Mountain Lion...Lion is no longer available in the store.

  • Should I upgrade to Snow Leopard/ Lion using a MacBook Pro with 2.26 GHz Inetl Core 2 Duo Processor and 2GB Memory? Can my old macbook take it?

    Should I upgrade to Snow Leopard/ Lion using a MacBook Pro with 2.26 GHz Inetl Core 2 Duo Processor and 2GB Memory? Can my old macbook take it?
    thanks

    Yes. You should be fine with Snow Leopard, but Lion requires a minimum of 2 GBs of RAM. If you upgrade to Lion I would first upgrade your RAM to at least 4 GBs if your model supports it. Also, see:
    How to Install OS X Updates Successfully
    A. Repair the Hard Drive and Permissions:
    Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade:
    Purchase the Snow Leopard Retail DVD.
    Boot From The OS X Installer Disc:
    Insert OS X Installer Disc into the optical drive.
    Restart the computer.
    Immediately after the chime press and hold down the "C" key.
    Release the key when the spinning gear below the dark gray Apple logo appears.
    Wait for installer to finish loading.
    E. If updating:
    Download and install update(s) 
    Use Software Update, or
    Download standalone updater(s).

  • HT1444 How can I upgrade the OS on my 5 year old MacBook Pro 17.  It is currently running 10.4 (Tiger).  I have an IMac 27 running Lion but have Snow leopard discs which came with the purchase.  Can these be used to upgrade?

    If they are the grey discs which came with the iMac, then they will be machine specific and will not work on the MBP anyway. You will need to purchase a retail copy of Snow Leopard from the Apple Store for about $29 and upgrade from that. I presume your MBP is Intel and not G4.

  • Hi, Hi, Hi  I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard. The updated the combo update. Now stuck on blue screen at start-up. Need help. Greatly appreciated. Thank you.

    Hi,
    I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard.
    Then updated the combo update. Now stuck on blue screen at start-up.
    Need help. Greatly appreciated. Thank you.

    Downgrade Lion/Mountain Lion to Snow Leopard
      1. Boot from your Snow Leopard Installer Disc. After the installer
          loads select your language and click on the Continue
          button. When the menu bar appears select Disk Utility from the
          Utilities menu.
      2. After DU loads select your hard drive (this is the entry with the
          mfgr.'s ID and size) from the left side list. Note the SMART status
          of the drive in DU's status area.  If it does not say "Verified" then
          the drive is failing or has failed and will need replacing.  SMART
          info will not be reported  on external drives. Otherwise, click on
          the Partition tab in the DU main window.
      3. Under the Volume Scheme heading set the number of partitions
          from the drop down menu to one. Set the format type to Mac OS
          Extended (Journaled.) Click on the Options button, set the
          partition scheme to GUID then click on the OK button. Click on
          the Partition button and wait until the process has completed.
      4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

    Negative reviews are common place here as it is a trouble shooting forum. If you want to read the advantages, improvements and new features then go to the Apple site. If you are running Word 2004, Early Adobe suite, etc which are PPC programs, then don't update. Go to Apple logo in upper left menu bar, open About this mac > More Info > Software >Applications and sort by 'Kind' and look what PPC programs you have installed. If you are not prepared to upgrade these programs, then do not update to Lion.
    There are plenty of threads to read up on about this here. But remember that 99.9% of comments will be negative, even though the forums represent only a tiny fraction of the Millions of Lion Downloads purchased and installed with no issues at all. So basically it's your call.
    Good Luck

  • My Dad gave me his old Macbook Pro and I downloaded another version of Lion so it's tied to my ID and it worked but I cannot download and iLife apps at all? It doesn't even give me a choice to purchase it just say accept?

    My Dad gave me his old Macbook Pro and I downloaded another version of Lion so it's tied to my ID and it worked but I cannot download any iLife apps at all? It doesn't even give me a choice to purchase it just say accept? And gives me a dropbox that says that these apps are tied to another ID and I need to log into that ID in order to download it.

    The Apple Support Communities are an international user to user technical support forum. As a man from Mexico my first language is Spanish. I do not speak English, however I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
    This is a common issue with second hand Macs. The iLife apps came bundled free on this Mac and they are registered to your dad's Apple ID. The only way for you to acept them into your Apple ID is for you and your dad to contact Apple Care, explain that he has passed the Mac to you and ask that the iLife apps be released from your dad's Apple ID so that you may accept them into your Apple ID.

  • How to install windows 7 on Old Macbook Pro 15'inch 2.3 Core 2 Duo

    How to install windows 7 on Old Macbook Pro 15'inch 2.3 Core 2 Duo:
    I want to known how to install windows 7 on Old Macbook 15'inch 2.3 Core 2 Duo by using usb
    I try many time, but after restart bootcamp partition, apple show blinking folder error
    I think this firmware not support to install windows by usb
    NOTE:
    I Cannot install Apple New OSX Mountain Lion, Mavericks etc in this MAC
    If I cannot install windows 7 on this MAC, so tell me what I will do with this MAC  ? 

    I agree with the optical drive, mine acted strange, and i thought people were crazy and my drive was shot, but a simple cleaning disc worked miracles.
    But- are you trying to reboot with both the USB install and the DVD install both plugged in?  that would definitely cause confusion.
    Do this, reboot with NOTHING plugged in.  Once you hear the Mac chime, immediately press and hold option.
    You should only see the Mac HD, and Recovery Partition.
    THEN plug in your external DVD, and wait a min or two, you should see a disc icon appear next to the recovery partition that says something like windows.  If that doesnt appear after a min or two, unplug it and put the USB stick and do the same thing.  I had to do it this way on my mid 09 MBP.
    Let me know if this works to start the install.  If not we may have to start over with Bootcamp Assistant

  • I have had to "re-instate" "Mail" on my 5yr old Macbook Pro after it got "lost"during an s/w upgrade to Snow Leopard v10.6.8. In reinstated version all my Email archive folders are now missing from the screen. How/where do I find them ??

    I recently purchased Snow Leopard v10.6.3 in order to upgrade the OSX platform on my 5 year old Macbook Pro. That loaded without trouble. Then I needed to do an online upgrade from 10.6.3 to 10.6.8 (via 10.6.4) and there the trouble commenced !! Somewhere along the way, the "Mail" application simply disappeared! On advice from Apple telephone support, I did a "selective" reinstall of "Mail" from the Snow Leopard disk, but the version of Mail it loaded (v4.5) was wrong for use with OSX v10.6.8 and so it kept asking for the 'latest" version (v4.6) and just would not work. I tried a "Fix" download provided on the Apple site, that didn't work.
    I spent 2 hours at the Genius Bar of my local Apple Store and they finally found a fix, after some difficulty. Apparently there had been a programming error somewhere in one of the Apple update downloads.
    So now I have "Mail" back - but the Mailbox folders now not as they were before - particularly they do not contain my archive Folders that I had been using to store certain historic emails.
    I think the folder structure on "Mail" is now identical to that on my "BT Yahoo" screen - whereas before they had been different. My local Apple Store told me that it was practice now to synchronise the "Mail" screen and (for example) the BT Yahoo screen to be identical. This is well and good going forward - but does not help me with access to my historic "email filing system" !!
    Anyone help me find those missing folders ??  They must be stored somewhere, but where ??!!
    Cheers

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

  • How can i transfer data from old MacBook Pro, which is too old to update time machine, to the newest MacBook Pro?

    I recently bought a new MacBook Pro, and wanted to transfer all the data from my old MacBook Pro, but I get the message saying I need to update time machine on my old one in order to use time machine. However, my old one is too old to update. So I decided to use the cable to transfer, because I heard I can do it that way even though it could take time. But I have no idea what to do...
    Can someone help me?

    A Basic Guide for Migrating to Intel-Macs
    The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate.  Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
    Classic Environment, and subsequently any Mac OS 9 or earlier applications
    Screensavers written for the PowerPC System Preference add-ons
    All Unsanity Haxies Browser and other plug-ins
    Contextual Menu Items
    Applications which specifically require the PowerPC G5 Kernel extensions
    Java applications with JNI (PowerPC) libraries

    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius  work properly on Intel-Macs with Leopard.  The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.  Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

    OS X Lion: How to use Migration Assistant to transfer files from another Mac
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs.  The initial section below discusses Target Disk Mode.  It is then followed by a section which discusses networking with Macs that lack Firewire.
    If both computers support the use of Firewire then you can use the following instructions:
    Repair the hard drive and permissions using Disk Utility.
    Backup your data.  This is vitally important in case you make a mistake or there's some other problem.
    Connect a Firewire cable between your old Mac and your new Intel Mac.
    Startup your old Mac in Transferring files between two computers using FireWire.
    Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
    If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
    1. Set up a local home network: Creating a small Ethernet Network.
    2. If you have a MacBook Air or Late 2008 MacBook see the following:
    MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- What to do if migration is unsuccessful;
    MacBook Air- Migration Tips and Tricks;
    MacBook Air- Remote Disc, Migration, or Remote Install Mac OS X and wireless 802.11n networks.
    Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.

    If you need to transfer data for other applications please ask the vendor or ask in the  Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
