Tiger vs. Leopard on a "Tricked Out" G4?

I have a Sawtooth G4 that I've upgraded in just about every way imaginable:
1.7 GHz Sonnet processor
2 GB RAM
128 MB 7200 RPM hard drive
128 MB ATI Radeon 9800 Pro video card
I run graphics applications such as Photoshop and InDesign on this Mac, and find they're somewhat sluggish. Additionally, my processor usage goes to 100% even if only a few applications are running.
I figured that the upgrades I've made would allow my Mac to run Leopard, which it does. But would I see any improvement in performance using Tiger?

Well, I don't know if it's in the cards for you, but replacing that 5400 RPM disk with a faster one would help, but a modern SATA drive with 16/32 MB buffer will really speed OSX up on any version, or for more speed...

  • Client Upgraded from Tiger to Leopard Can No Longer Connect to Tiger Server

    I just finished upgrading a G5 2GHz DP Powermac from Tiger to Leopard. This was an Archive and Install upgrade with importing the old settings. After verifying the account migration, including .Mac connectivity, and fixing all 3rd party software compatibilities/upgrades, I tried to connect to our Tiger 4.11 server by clicking on the server's Icon in the Shared section of the Finder Sidebar. The finder then switches to browse the the server for shares: "Connecting..." is displayed under the tool bar, with a "Share Screen..." and "Connect As..." buttons to the right.
    At this point the "Connecting..." remains displayed with the spinning circle in the bottom right of the Finder window.... spinning. This situation continues for several minutes until is seems the system gives up.
    If I click on the Path button on the Tool Bar, and go up to the Shared level, ALL the Shares on the Network are displayed, including all the Tiger Client machine shares. I can click on the triangle beside the Tiger Client's icon, and all the drives and home directories on the Mac are listed. All the client shares can be accessed without any issues. NOTE: There are no other Leopard clients on the LAN.
    Prior to the Leopard upgrade, this client could connect to the Tiger server as well. All the other clients on the LAN can access the Tiger server also.
    On the Leopard client I have tried clicking and the "Connect As..." button and using the menu "Connect to Server" and specifying the server's IP, and I get the same "Connecting..." message with a "non-connecting" result.
    I can only assume that somehow the Account Name and password are not being passed correctly. But, using "Connect As..." should resolve that. However, "Connect As..." does not give me a user/password window!
    If I check the AFP Access log on the Server, the only messages displayed are "Mounted Volume..." No messages in the error log, and no messages in the "Connections" section.
    Can anyone help me figure out why the Leopard client can not connect to the Tiger Server?
    My apologies if the description of my problem is a bit disjointed. I have been thrown into server admin and am learning "Trial by Fire".
    Any help or suggestions on how to resolve this issue will be greatly appreciated.
    Thanks

    OK. A quick update.
    After waiting for about 10 minutes for the rotating circle in the bottom right corner to stop, I was able to click on the "Connect As..." button. It took another 10 minutes, but the Connect As window eventual popped up. I entered the Userid and Password (saving to Keychain) and was able to see all the sharepoints on the the server. I browsed all the connected drives and folders without issue.
    I then disconnected from the server. Reviewing the AFP logs on the server shows messages for the connection Login and Logout.
    I then tried to reconnect to the server, and again another 10 minutes wait, although this time the Leopard client eventually connected automatically with the proper User, as per the AFP logs confirms.
    Although, the client can now connect to the server, for it to take 10 minutes will be unacceptable to management, not to mention the end user. Tiger clients can connect in a couple seconds!
    Is there a way to reduce the Leopard login time to, say, a couple seconds, like it does with the Tiger clients?
    Again, any help or suggestions would be greatly appreciated.
    Thanks

  • Can I run Tiger and Leopard on the same computer

    Hi folks.
    I've been meaning to install Leopard for ages but have never got round to it (I bought the retail box when it first came out). I have upgraded my RAM to 2GB and my hard drive to 320GB with no problems.
    My upgraded hard drive has been partitioned into 2 equal parts of 160GB. These appear on desktop as Mackintosh HD1 and HD2. HD1 is the disk with all my files, music, OS etc and HD2 is empty
    I have 2 bootable clones of my present system - one is on a 160GB external and the other is the original 80GB HD that I replaced.
    My question is this - can I install Leopard on to my 160GB external HD, then clone it on to the empty HD2. If I do this would I be able to run both Tiger and Leopard on the same Macbook?
    Is there any problems with this plan? Would I be able to transfer between the 2 OS and how do I install Leopard on the external drive. Is it just a case of inserting the Leopard DVD and choose the external drive as the target?
    As usual thanks in advance
    Del

    # Original Tiger in the internal HD, New Leopard in the external HD.
    # New Leopard in the internal, Legacy cloned Tiger in the external.
    # Split internal, one partition with Tiger, another with Leopard.
    Leopard is backwardly compatible with older Macs, just make sure yours fulfills the minimum system requirements, both use the same filesystem format, so each can see the other. You can't run both at the same time, unless you purchase the server version of Leopard and run it virtualized. 99.9% of Firewire external HD's are bootable, some USB's are bootable but have to test first. You can choose which system to boot from by pressing the Option key at boot time, before the chime. Just make sure the external HDD is plugged in and turned on if that's where you want to boot from.
    When I migrated my PBG4 from Panther to Tiger, got an external FW HDD, cloned Panther onto it, upgraded using Archive and Install, cleaned up, customized and tested it. When I was satisfied all was ok, cloned the original Panther onto another partition of the external HDD, wiped and tested for failure the internal HDD, then cloned the known good and tested Tiger into it. Only thing that died along the way was my old and ancient Photoshop v2.x, that refused to run on Tiger.

  • Mail no longer working after upgrade Tiger to Leopard

    I know that there are some reports out there on the Internet but I can not find a solution that I trust. i upgraded from Tiger to Leopard and ever since my Mail program has completely disappeared. it is no longer in the dock, it is no longer in the applications folder and I went into the Mac Harddrive and found i. I dragged the icon on the dock and when I now start Mail the bar on top of the screen shows me that it started, but no windows come up. Under File most options are grey. i can see that all my mailboxsettings are still there. I have Entorage 2004 as my default mailprogram, but that gave never problems in the past and I use Mail for my google account. Under View in the menu almost everything is grey.
    can someone help please? thanks so much.

    In addition the article cited, if you ran 10.3 or earlier prior to upgrading to Tiger, once-upon-a-time, you might also need to remove two files with MessageSorting in their names.

  • FireWire slows from 60MB/s to 16MB/s when switching from Tiger to Leopard

    Hi Folks
    This is a big problem for FCP users so I'm posting this here (as well as on the Leopard discussion board). After upgrading to Leopard I noticed a substantial drop in FireWire disk performance. While in Tiger I could sustain 60MB/s against a FireWire800 RAID0 drive. After doing a clean install of Leopard the same drive wouldn't go past 16MB/s reading and about 30MB/s writing.
    Note that I'm well aware of the usual suspects - Spotlight, Time Machine, some other process hitting the disk. This is NOT what's going on.
    I can boot back and forth between Tiger and Leopard and see the above-mentioned speed change. I even went to the Apple Store and booted my machine off of their vanilla installs of both OSes and verified the problem.
    Turns out the specific version of the MacBook Pro is important here. The latest refresh does NOT repro the problem. However, my version, MacBookPro2,2 the first refresh (which was the first to have a FW800 port) DOES repro the problem.
    I've tried this with various Oxford-based FireWire drives and seen the same behavior. Anyone else have this version of the MacBook Pro willing to try this and post their results? You could use most any benchmark program to test throughput - Xbench is fine and free - but I've been using this one (free as well and one-button easy):
    http://www.aja.com/ajashare/AJAKONA_System_Testv2.app.tar
    Thanks and let's hope Apple fixes this one quickly!

    You might consider getting a firewire 800 card and see if that helps. Maybe they'd let you try one out at the apple store. Never a bad idea to have a second firewire bus anyway.
    Or even better, get a SATA card and some external sata drives (I've got both a firewire800 and sata card for my macbookpro - but I've got the earlier model that only has firewire 400 internally). btw, I'm still on tiger.

  • Switching from Tiger to Leopard or Snow Leopard

    Hi-
    I have a desktop G5 iMAc running OS 4.10.11 and need to upgrade. What's the process and how much trouble am I going to get into doing this with my current software, mail programs, etc.?
    Thanks-
    DMitzelfeldt

    First, a G5 won't run Snow Leopard, so that's out.
    The main problem with Leopard will be finding a copy. If you call Apple (try to avoid their regular sales department which will tell you to buy a computer capable of running Snow Leopard) they may still have copies. Once a newer OS comes out they pull all older versions from their shelves and online store. Otherwise there's the used market but expect to pay around new prices anyway.
    As for software, the main thing you'll lose is Classic and any OS9 generation software. I'd ask about specific software issues on the Leopard forum since they are the ones who have actually experienced a switch. I don't think there are any major ones unless you're already running ancient software.
    By the way, one thing you can do for free is update to Tiger 10.4.11 since your profile says 10.4.10

  • Re: I don't have a dual-layer drive, can I install Tiger or Leopard?

    "This tip is ready for consideration"

    Hi a brody,
    Maybe it's my training that states to focus on what we can do, but I'd suggest changing the double negatives to positives. Let me know as that does leave out the "if and only if" implication of the "can't" statements which you may want to keep.
    Mac OS X 10.4 Tiger, and Mac OS X 10.5 Leopard come on what appear to be larger than 4.7 GB discs. This does not mean you need a dual layer drive to install them. Some Macs capable of installing Tiger or Leopard came with a built-in CD-RW, or CD-ROM drive. For those a compatible Firewire DVD drive for booting Mac OS X can work instead of replacing the internal drive. Tiger also came in a limited edition Media Exchange Program CD installer package, which you may be able to find in the open market. The limitation for each is dependant on other hardware:
    1. If your Mac shipped new with no Firewire, you {color:red}may be able to{color} install Tiger {color:red}with{color} a special third party addon software known as XPostFacto.
    2. If your Mac shipped new with less than 867 Mhz built-in processor (including dual processor 800 MHz or less), you {color:red}may be able to{color} install Leopard {color:red}with{color} a special third party addon software known as Leopard Assist.
    3. If your Mac shipped with a processor upgrade card installed, and #2 is true, a firmware update may be available from the processor upgrade card vendor that allows Leopard's installation.
    4. Tiger {color:red}needs{color} at least 256 MB of RAM.
    Leopard {color:red}needs{color} at least 512 MB of RAM.
    If you have a lot of dashboard widgets, you may need to increase RAM to improve performance on either operating system. The RAM needs to follow Apple's specs to ensure smooth operation. Only get RAM with a lifetime warranty.
    5. Officially you need for Tiger:
    "At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools" from: http://support.apple.com/kb/HT1514
    And officially for Leopard you need:
    "9 GB of available disk space or more" from http://support.apple.com/kb/HT3759
    However, I would add to that if your hard drive doesn't have at least 15% of the drive free in addition to that, you may experience significant slowing down in the operating system function. This number has been arbitrarily discovered by many users.
    6. When installing Tiger or Leopard, if your machine shipped with Panther (10.3) or earlier, be sure to get the retail Tiger or retail Leopard.
    The Tiger installer is a san serif gray and white X with a spotlight on the center of the X on a black background.
    The Leopard installer is a san serif black and gray X on a pink galaxy centered on a black background.

  • "Moving" Tiger and Leopard OS's from G4 (32b) to G5 (64b)

    I plan to image Tiger (10.4) and Leopard (10.5) from my Power Mac G4 (Quicksilver 2002) to a recently acquired a Power Mac G5 (Early 2005). My questions are:
    1. Tiger and Leopard were installed on a G4, a 32 bit processor, but the G5 is a 64 bit processor. Do I need to do anything after I’ve “installed” the G4 Tiger and Leopard on the G5 to have them function as 64 bit Operating Systems (a.they can detect which processor they are installed on automagically and don’t need my intervention OR b.I have to toggle something OR c.I have to reinstall one/both of the Operating Systems on the G5 for them to function as 64 bit Operating Systems)?
    2. How can I tell if the OS is running as a 32 bit or 64 bit process?
    TIA.

    Hi Barubin,
    I'm no expert on OS X's internals, but I believe Tiger and Leopard's kernel still is 32-Bit, but allows 32-64-bit bridging. In Leopard's Activity Monitor I can only find two apps running in 64-Bit mode:
    usbmuxd
    IIDCAssistant
    The best way of getting 64-Bit is to upgrade to Snow Leopard on Intel, I'm afraid.
    Your target-disk method or BDAqua's suggestions should work just fine, but I usually find hdiutil to be generally more reliable, plus I can keep around a system image for safety's sake. When I say reliable, I mean that you can always interrupt the image creation by using CTRL-C or check whether it is actually throwing any errors. The GUI has hung on me on occasions. I also love UNIX, which helps!
    I've never done a speed comparison between Disk Utility and its CLI counterparts, but I like the verbosity/flexibility provided by the CLI. It's a matter of taste, really. If you're not comfortable using the CLI, stick to the other options.
    The purpose of asr -imagescan (asr stands for Apple Software Restore), is to rebuild the target image and replace it with a checksummed and reordered (optimised) version, so it can then be verified against the contents of your target volume after you're restored the data. Also, scanning the image allows you to do a block restore, which is effectively a blazingly fast blind copy. In a matter of minutes you can easily restore 15 GB of data into your chosen volume, as opposed to not scanning it with asr or Disk Utility and the restore operation defaulting to a normal image mount --> data copy operation, which is slow and inefficient. It's a tradeoff really. You can wait for ages restoring, or creating the image
    I rather wait for image creation since it's the safest and cleanest option data-wise.
    Check out:
    $ man asr
    $ man hdiutil
    I'm confident it will all work just fine with your heart transplant!
    Cheers

  • Just upgraded Tiger to Leopard.  Clarisworks not supported.   I can successfully convert CW4.0 doc's to AW6.0 doc's using MacLink Plus Deluxe but the problem is I than cannot print them or convert to PDF, either.

    Just upgraded Tiger to Leopard.  Clarisworks not supported.   I can successfully convert CW4.0 doc's to AW6.0 doc's using MacLink Plus Deluxe and then work on them but the problem is that I cannot print them.  Neither can I convert to PDF.

    If I was trying to get someone else to do my work,
    I wouldn't be posting this saying what I have said
    would I? I'm not unwilling to do the work myself.From what was stated in your OP, it seemed that you
    were.I'm sorry if it seemed that way. I don't want something for nothing. I've spent MANY hours, which I don't have, trying to work this out. I have hit a point where I don't think my expertise is going to solve the problem. That's why I've turned to some experts who might say something along the lines of, "Hey, I know what that is...you're compiling against... and on the Unix box, it's compiling against..." I was NOT looking for something like, "See the code below that fixes your problem."
    The only problem is that I don't have direct access
    to the sun unix machines I'm running the app on,
    so I can't run a profiler on it. Ah, okay. So the only knowledge you have of how it
    performs on those machines is from your instructor
    running it and then telling you how long it took?No. I can SSH into the servers and run the program from a command line. But I wouldn't be able to install any profiler programs.
    You could ask your prof to run it with -Xprof or
    -Xhprof or whatever. Or you could put in a bunch of
    timing statements to get a rough idea of which parts
    are making it take that extra 39 minute or whatever.is -Xprof a java command line option? If so, I will look into doing that. Maybe it's available on the machines at school. Thanks for that input.

  • I just upgraded my older G5 from tiger to leopard and it is now at 10.5.8, I was unaware that the new system did not support the classic envoirnment and cannot access my 6.0 version of Photoshop, which I use often...how do I get P.S. going again?

    I just upgraded my older G5 from tiger to leopard and it is now at 10.5.8, I was unaware that the new system did not support the classic envoirnment and cannot access my 6.0 version of Photoshop, which I use often...how do I get P.S. up and going again?

    Niel...
    I installed Leopard 10.5.6 and then it upgraded to 10.5.8, when I installed it I had the old info saved to a "previous systems" folder, where most of my artwork, etc. were saved, I have a one terabyte Lacie backup that unfortunately did not work as it was intended...it saved the new info and not the old. I did look into the system preferences folder and found the classic file, of course it wouldn't launch...but I have the old G 5 startup discs and will try to do it as you stated. I will try also to move it out of the previous folders file to my hard drive and see how that works.
    thank you for your time and help,

  • Mail app on Tiger and Leopard no longer bring in mail from non-apple servers

    My husband's computers use Tiger and Leopard (10.5.8) to access his email on the Mail program.  His mail is from Comcast and uses the Comcast server, not apple or iCloud.  His mail suddenly stopped working a couple of days ago.....as it did on one of my machines that still uses Tiger.  He had not done any updates that could have broken the software.  He does not have iCloud except on his phone and he doesn't even have a .mac address.  There is no reason for the comcast server to not be able to be accessed by Mail app.
    He did finally update everything that needed it and it still does not work.  Why would Apple's change over to iCloud break email access from other servers and how can we fix it.  He really doesn't want to do his mail on Comcast's web site as it's slow and awkward.
    Thanks for any help you all can offer.
    Paula

    Thank you for answering.
    I know it shouldn't have been able to stop those accounts from working on the Mail app but it did.Out of 4 machines, 3 stopped working at the same time.  The 4th is on Snow Leopard and continues to get my Comcast mail.  But the one Tiger machine and 2 Leopard machines no longer access any mail from any server.  Shouldn't be possible, but it happened.
    I don't want to delete accounts because I don't want to lose the old email in the different folders on there and the software is acting so bizarrely, I know the mail would be lost. 
    I checked all the settings and compared them to the one on Snow Leopard that still works.  The settings are all the same.  The only difference is the OS.
    And to make things more frustrating, I found that several entries in my Contacts book were either deleted or scrambled with phone numbers for person A in the entry for say, person C.  I mean it's a real mess and this all happened after I got a notice from Apple that they were shutting down all their mobile me stuff and sending everything to iCloud.  Syncing is obviously a mess now and I don't even want my stuff sync'd there.  My husband has never even signed up for iCloud but since he has an iTunes account, thus an Apple acct, they appear to have automatically put him on iCloud too.  And....mail quit working unless he gets it on his iPad or iPhone.
    We're fed up with Apple's insistence on total control of it's customers' previously working equipment.  We have no desire to upgrade to Lion or it's next iteration. We have been happy with what we have and asked only that it continue to just WORK. 
    It's become a rotten Apple in the past few years.  We've been with them a long time but  we're watching other companies closely for something that will do what we need without the draconian control.
    I have a feeling the only way to "fix" Mail.app is to upgrade to Lion and we won't be doing that.
    Thanks again.

  • "Clean" update from Tiger to Leopard

    Hi folks,
    I plan to update to Leopard when it comes out next week. Since I'm on my first Mac and don't have any experience with installing/upgrading Mac OS I've got a couple of questions.
    What I'd like to do is to back up all my stuff on an external drive (I already do that for a while) and then do a clean install of Leopard (that is: erase the harddisk before installing instead of a "live" update). The reason I'd like to do this is that I found out that there's a lot of unused stuff that came with the pre-installed Tiger on my MBP that just wastes space. And some third party applications/drivers that I wanted to check out when I was becoming familiar with working on a Mac also waste space, and a clean install is good way to get rid of this cruft
    So the first question is: will I be able to do an "expert" install where I can influence what will be installed (at least to a degree, e.g. select which language files to install) ? I guess only people with access to beta releases of Leopard will be able to answer that, so how is Tiger in this respect ?
    Let's assume I now have a clean install of Leopard. I now want my old data back. I know I can backup my iTunes music on CD's/DVD's and should be able to load them back (anything I would have to look out for here ?). I found a document describing how to handle other Apple applications at http://docs.info.apple.com/article.html?artnum=301239 , do I need to look out for something else (apart from third party applications) ? My biggest concern is Keychain, BTW.
    Thanks for the help,
    Marc

    Hi folks,
    so I'm on Leopard now Here's what I did. Sorry if I misname programs because I've got the german version and translate back to english.
    First, I made a "normal" backup using iBackup just to be sure, then did the real backup: I cloned my Macintosh HD partition using Carbon Copy Cloner to an USB disk. I made sure that I was able to boot from that partitition (I've set it as the start volume in the system preferences and it came up fine). I also made a backup of my bought music in iTunes.
    After double-checking back and forth I decided I'm ready and went and bought Leopard. I then started the installer and used the disk utility to erase the Macintosh HD volume. I customized the install to not install the languages I don't want and not install the printer drivers (3.8GB...). The install went fine and I was presented with the migration assistent.
    I chose to migrate all accounts except my main account because I wanted to only copy the stuff I really need. Unfortunately I don't remember what else I've checked/unchecked. So I was finally able to log in using my administrator account and created a new main account. And now to my manual migration:
    One of the first things I had to do was fix the owner of my account in the backup: because I haven't migrated it the user ID was wrong, so I had to "su" to my admin account and then "sudo bash" to become root and "chown -R myname:staff /Volume/Backup/Users/myname". No idea why the new main group for my account is "staff", but "id" says so. I guess there's a good reason for Apple to do that
    First thing I wanted to migrate was my KeyChain. I guess I wasn't very clever, but it worked: I opened the KeyChain Helper and added my old KeyChain. I pressed Apple-A to mark all entries in my old keychain and moved them to my new keychain. It worked... but I had to enter my password for each entry, and there were a lot of them :-/
    Importing the Safari bookmarks was a peace of cake: there's a "Import bookmarks" menu entry. Nobrainer.
    Then I copied my iPhoto folder and realized there's no iPhoto application: so I popped in my MacBook Pro installation disk, ran "Install Bundled Software Only" to install iDVD and iPhoto. Haven't tried iDVD yet, but iPhoto seems to run fine and only copying the iPhoto directory was enough.
    I didn't "migrate" my Mail settings as I'm using IMAP, so just entering the data again was faster and sure to work. I haven't really used the addressbook so I haven't tried migrating it.
    Re-importing my bought music in iTunes using the backup DVD was also a no-brainer and I re-added the rest of my music to the mediathek (it still doesn't support Ogg Vorbis...).
    The rest of my stuff are documents that don't need any special handling so I copied them with Finder. Haven't checked whether Heroes Of Might And Magic V and Civilization IV run but so far everythings seems to be fine. I had 9GB of free space before the update, now it's 40GB... I need to subtract a few GB because of the games and apps I need to reinstall, so let's say 30GB but all in all it was quite success
    Bye,
    DarkDust

  • Help - Migrating from Tiger to Leopard Server via Apple Maintenance Program

    Hi, I'm to upgrade an Apple Xserve running Mac OS Tiger to Leopard. There was an Apple Maintenance Program purchased for this Xserve. I plan to do a clean install on the server, however, I don't know where to find Leopard's serial number or if I need one or if I can do a clean install via AMP.
    This was the first AMP sold in my country I think and the VAR was a little clueless, it wasn't our plan to upgrade until now and I don't know who to ask.
    I have the media, but it wasn't the one that apple sent, the VAR just made me a copy of a Leopard Server. I have the license program agreement, there it is stated the License Number (amp - xx -xxxxx format), the License Date, the Sales Order # and something label PO.
    Could somebody please point me out how should I proceed? The server is being moved from its intended use so a clean install is no problem (and prefered).
    Thanks in advance
    Rafael

    You should get the media directly from Apple complete with "xsvr-"serialnumber in an envelope in the (snail-)mail.
    We have customers which didn't get the serial or DVD in the envelope so we had to contact Apple again.

  • Upgrade from tiger to leopard on a power mac G?

    can i upgrade from tiger to leopard on a power mac G5?

    Yes, however, read about the pitfalls below.
    Mac OS X 10.5 was release October 26, 2007.  Its 10.5.8 update is the newest operating system available for PowerPC Macs that meet its requirements.  It is available occasionally by calling Apple online store's phone number, even though the website does not show it.  Many want to upgrade to Leopard because of i-Devices (iPhone, iPad, iPod) bought saying iTunes 10 or later is recommended.  To check if that really is required, look at the i-Device requirements section of this tip
    If your Mac is Intel, and running 10.4.11 or earlier, and meets the hardware requirements of 10.6, a less expensive upgrade solution is to upgrade to 10.6 directly.  No need to upgrade to 10.5 unless your software won't run in 10.6.
    Software listed for Intel Mac and PowerPC Macs can run on 10.5 for the platform indicated in the link. For Leopard you need
    867 Mhz on a single processor or faster (1 Ghz and higher are faster).
    256 MB of RAM (preferably 512MB of more based on arbitrary experience).
    9 GB of hard disk space (arbitrary experience adds another 15%) free.
    Macs newer than August 28, 2009 can't run Leopard, and require a minimum of Snow Leopard.
    Dual booting Mac OS 9 and Mac OS X 10.5, check this tip:https://discussions.apple.com/docs/DOC-1757
    Classic is not compatible with 10.5.  10.4.11 on a PowerPC Mac or earlier is needed for Classic.
    Mac OS X 10.5 is the earliest version of Mac OS X that will run iTunes 10.  This is necessary for numerous i-Devices (iPad, iPhone, and iPods).  To find out which require it, see this article
    http://en.wikipedia.org/wiki/ITunes_version_history
    Should you require only iTunes 9, and are running a minimum of 10.4, backup your data at least twice, check in Apple menu -> About This Mac if you have a G3, G4, G5 (which is PowerPC), or Intel Core (which is Intel) make sure you are running 10.4.11 PowerPC or 10.4.11 Intel (depending on the aforementioned processors), and download iTunes 9.2.1.  The only reason you should upgrade to 10.5 is if some other software is required.
    Boot Camp is only available on Intel Macs with 10.5 and higher.
    Time Machine backup software first appeared in 10.5
    You have several options of installation which are explained here: https://discussions.apple.com/docs/DOC-2209
    All of which I recommend you backup your data at least twice before upgrading, and have sufficient disk space to install, and all your third party applications and drivers are known to be Leopard compatible, and after backing up your data you dismount and disconnect all but Apple keyboard and mouse and if there is an external display, that too. And just before you install repair permissions.
    If any of the above terms confuse you, ask on the Discussions board what they mean, and one of the people who knows will gladly assist you.
    You must use the installer disc that looks like *, and does not say Upgrade, Dropin, or OEM, if you choose to upgrade to Leopard.

  • Just curious... comparing Tiger and Leopard???

    Maybe some of the older mac users can answer this question for me. I just got my macbook in June 2007, preloaded with Tiger. Tiger worked perfectly, no bugs, no crashes. Now it seems with the upgrade to Leopard that there have been lots of problems with the OS, and everyone keeps proclaiming how they like Tiger so much better. This got me to wondering, when exactly was Tiger released, i.e. how long did Apple have to fix all of its bugs? Does anyone remember, when Tiger was first released was there as much of a problem upgrading from the old OS (Panther?) as there is now with the upgrade from Tiger to Leopard?
    Just wondering...

    A lot of people like what they already have and don't want to work at optimizing their system, upgrading or changing to new programs, or buying new hardware with performance in mind. There are always hidden costs to upgrading to a new OS. If you don't want to pay for these costs, then there is no reason to pay for the OS.
    Owners of older Macs should run XBench 1.3 before deciding to overload it with a new OS that's designed to run on totally different hardware than they purchased just a few years ago. If your overall score is above 65 you will probably do OK, not great, just OK. If your score is above 100 then you will probably do very well. These numbers are subjective - without authority, YMMV.
    My MBP benches at 139 with all tests enabled. 183 with the hard drive test turned off. This machine has a good chance of being able to keep up with Leopard and the next cat.
    I've maxed out the ram, and upgraded the hard drives. None of my programs are running PPC code. Every program I use is specifically designed to run on Leopard (just bought the new SuperDuper today).
    I did the Leopard upgrade after I cleaned up Tiger. Make sure that Activity Monitor says every process or program is running for your actual platform. In my case everything says Intel. Everything was backed up to 2 different drives (one bootable).
    I had no problems with user accounts, and Time Machine has worked flawlessly.
    The only real bug I've come across in Leopard has been the need for including my DNS info in the network settings because my Mail program was sending messages with a 30 second delay.
    I never get a beachball.
