Still run Tiger on my Dual 2.7 PowerPC.  Benefits upgrading to Leopard?

Hello, I decided to put this post here, instead of in a more general hardware discussion, due to Logic Pro being my main app concern.
I am using a Dual Processor 2.7 PowerPC G5 Power Mac, with the latest version of Tiger. I have heard several mumblings about it not being entirely worth upgrading some powerpc machines to Leopard, due to Leopard not being tailored to run as beautifully, as Tiger was, on powerpc's. Is there truth to this? Is the chance of hardware failure increased? What type of performance might I expect upgrading to Leopard, with overall system usage, as well as with Logic Pro 8, when compared to Tiger? I would hate to have some of the responsiveness I currently have to be lost!
I I currently have 6.5 gigs of Ram installed.
Thanks so much for your responses! I would love to hear stories from people who have my same Power Mac model, as well as any other input!
=D

My 2¢:
I am using a Dual Processor 2.7 PowerPC G5 Power Mac
Slightly faster G5 than my old workhorse, which runs very nicely in 10.4.11
What type of performance might I expect upgrading to Leopard
If you looking for a boost, then IMO, none, or at best, very little.
Is the chance of hardware failure increased?
Very unlikely. There's no reason that an OS upgrade would affect hardware, other than any incompatibility issues which might arise.
I would hate to have some of the responsiveness I currently have to be lost!
You may.
I also have a MacPro with 10.5 and although it's a much faster machine, for me Logic is less stable. To be fair, this might be because of my external hardware.
The main question I have is why?
What advantages do you think Leopard may have for you? Time machine? Spaces?
If your system already runs well, is stable, and does everything you need, why jeopardize it?
If it ain't broke…

  • Can I install Tiger in a Dual 500 MHz PowerPC G4?

    Can I install Tiger in a Dual 500 MHz PowerPC G4, or is it better to stick with 10.3.9? I'm having some problems so I was going to wipe he hard drive and re-build everything from scratch o I was wondering if migrating to OS X 10.4.9 is worthwhile or even compatible with this PCU. Thanks.

    Yes you can run 10.4 on your dual 500, I have a dual 450 (I overclocked it to 550...) and it runs pretty fast. You need a minimum 192 MB of RAM to install it and a minimum 128 MB of RAM to run it. I would suggest having at least 512 MB of RAM when running 10.4.
    What problems are you experiencing? If it's just lagging and seeming slow it may just be worthwhile to clean some temp files and clean up your disk. IMHO, 10.4 is a much better system than 10.3, and runs much smoother. I can guarantee you that your system will run much smoother if you wipe the disk clean and put a fresh install of 10.4 on there, and also get a decent amount of RAM in there. After I upgraded my RAM to 1.5 GB, I noticed a substantial difference in speed, and got a lot less spinning color wheels. But one thing that you need to always keep in mind is to KEEP YOUR DISK CLEAN!!! Clean the temp files often and limit your internet downloading. If you keep your computer on all of the time, restart it every once in a while. There's a lot of little things you can do to increase speed in OS 10.4. Use spotlight and recent applications. Fill up your dock. Don't clutter the desktop, etc. There's plenty of articles on the net to help increase speed without adding anything else to your system, just navigating through the OS differently.

  • G5 Dual 2.7 - should I upgrade to Leopard?

    Tiger is fine, but just purchased standalone Leopard. Having buyers remorse after hearing that others with my configuration have not had a pleasant time.
    Need constructive input. Time is money with these installations -just want to make sure I should keep Leopard only on Intel Macs. Also- how about iMac G5?

    Hi Kurt Triffet;
    I am running Leopard on a PowerMac G5 Quad without any problems at all.
    But sine you say that Tiger is fine and that time is money, I would say that foregoing the upgrade to Leopard might be the best plan in your case.
    If you do decide to go ahead with Leopard, I would strongly suggest that you clone the system drive and test the clone to be sure it boots. Once you do that I would suggest you do an Upgrade to get to Leopard. With the clone as a fallback in case anything goes wrong you should be able to get back to the current working system very quickly.

  • Remote IP address invalid - not using Leopard, still on Tiger

    I am looking for help! I see many solutions for people having this problem who are on Leopard, but my work MAC is still running Tiger and I am now getting this error when someone tries to video chat with me. When I try and video chat with buddies, the error I get back is "Erica (workMAC) did not respond" (Note: Erica (work MAC) is my user name...). I did not have trouble with this previously. The only thing that has changed since the last time I video-chatted is that the static IP address our internet provider assigned to us has been changed, due to recent upgrades to the service in my area. I suspect this is a culprit, but cannot find out how to fix the problem. Suggestions?

    The Error 4 refers normally to one end being on Leopard and the problem being at then end.
    It is normally seen by the end without the problem.
    I have not seen it Tiger to Tiger chats.
    As you are on Tiger that does not preclude the others from being on Leopard.
    However I would still be interested in the new Internet Service.
    I have heard of situations during upgrades where in (Downstream) and out (upstream) data is actually over two routes to maintain speeds.
    Effectively the ISP routes you through two IPs in fairly simple terms
    This may have something to do with what is going on here.

  • How can I upgrade to Lion or Mountain Lion if I'm still using Tiger 10.4.11?

    I have an old (5 years +/-) MacBook that is still running on 10.4.11. I want to upgrade to a better OS but I think I need to increase the memory in the computer to be able to upgrade. Is this true? If so, how do I go about it?
    Thanks!!

    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
         Are my applications compatible?

  • Have old MacBook Pro running tiger 10.4 want to save date to external hard drive and buy newer MacBook and still use same drive. Any suggestions, most  WD drives say nothing about os tiger 10.4.

    Have old MacBook Pro running tiger 10.4 want to save date to external hard drive and buy newer MacBook and still use same drive. Any suggestions, most  WD drives say nothing about os tiger 10.4. The OS compatibility  is much newer on the data.  Totally confused. Not a computer person.

    I haven't checked reviews recently but there's a difference between bare drives and drives with enclosures.  Western Digital made some of the most reliable drives last time I checked, though the enclosures weren't all that great.  It is convenient to get both in one package but I usually buy a highly rated enclosure and then put a highly rated drive in it myself.  OWC sells some good enclosures but if they put a so-so drive inside of it then the package is only as good as its weakest component.  If you get a package from them, ask them what drive is inside (some vendors have no idea what's inside  -  went to an Apple Store recently and they couldn't tell me what was inside some of their Apple brand enclosures).  My first thought if buying a new drive would be to buy a OWC enclosure with a WD drive, but chek around because I may be out of date.
    10 years ago Seagate was one of the best drives. Now they rate poorly in reviews.

  • Can I run Tiger or Leopard with these specs? + why is computer so slow?

    I have an ibook dual USB with a 600 MHz Power PC G3 processor, 256 MB SDRAM. Right now I have 3.53 GB available on the hard drive. I need to be able to run Tiger on it for my work as an online writing tutor and freelance writer. I send files to Windows users, so I'd like to be able to run Leopard when it appears.
    Is there any way I can update this computer--more memory, faster processor?--so that it will run these operating systems without taking a million years and/or crashing frequently?
    Right now, it's running extremely slowly as is. For example, I just tried to open Systems Profiler to give more info about the computer, and after 2 minutes it still hadn't opened.
    I'm thinking I should spring for a new laptop when Leopard comes out, or maybe get one now with Tiger before my computer becomes totally fried.
    Advice? Thanks!

    Hi, and welcome to Apple Discussions.
    What is the hard drive capacity? You are running with it very full right now. I recommend keeping at least 5 GB available. Maybe you could do a bit of housecleaning to make a little more space available?
    I don't recommend installing Tiger on a G3 iBook. In my opinion, OS X 10.3.9 is the optimal installation for the 600 MHz iBook.
    How long has it been since you did any hard drive maintenance? If it's been awhile, try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
    You will see your normal desktop. Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say?
    Select the named boot volume in the left sidebar ("Macintosh HD" unless you've renamed it). Repair permissions on it.
    See if a little hard drive maintenance helps speed things up a bit.
    Additional RAM would help the speed a mite, but a new MacBook is likely the wiser choice.

  • Can you still buy Tiger?

    I want to upgrade to Tiger on a PowerBook G4 so it will be running the same system as other computers in the house. Can I still buy Tiger? All I can find in the Apple Store online is Leopard, and I don't want Leopard.

    You need to buy it from a 3rd party, and it's expensive ($150-200), unfortunately.
    Here's one example:
    http://hardcoremac.stores.yahoo.net/macosx10tire.html
    There are cheaper ones, I'm sure. You could try eBay/Craigslist. But, be careful! Be sure you are buying authentic retail discs - they will be black with the X. They will NOT be gray - those discs only work with the specific model and build they shipped with.
    Hope this helps...

  • I have a Macbook Pro 15" that is three and a half years old.  Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?

    I have a Macbook Pro 15" that is three and a half years old.  Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?
    I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
    This was my first Mac since an old Apple II GS.  After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc.  Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
    I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
    That said, any tips?
    Thanks
    It does have a crack on the left of the screen case about 3/4'' up from the bottom.  I've posted that as another question.

    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. Drive Genius provides additional tools not found in Disk Warrior.  Versions 1.5.1 and 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 was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or Lion 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. For more about malware see Macintosh Virus Guide.
    I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
    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 command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
    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 mode before 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):
    Carbon Copy Cloner
    Data Backup
    Deja Vu
    SuperDuper!
    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.
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little.

  • Recommend Panther or Tiger for QuickSilver Dual 1ghz?

    Hi, I'm faced with re-installing my OS, and would like a recommendation as to which OS to use. I'm currently using 10.3.9. Aside from the usually application compatibility issues, is 10.4 going to be to demanding on my old beast, or is it a good match?
    I really have no problems with 10.3.9, other than an undetermined issue that is forcing me to re-install. Also, I'll be using a fresh disc, and retaining my old setup during the transition.
    thx,

  • Can you run Tiger and OS 8.6 on the same computer? RE: Repair Permissions

    Hello,
    I don't fully understand how "Repair Permissions" work and when it is needed and therefore I would like to post this question for some clarification. Using "Repair Permissions" for troubleshooting is a controversial issue. I read this interesting opinion about Repairing Permissions and now I am concerned that it may not be safe for me to install my old OS 8.6 on my OSX installed computer due to a "permission" conflict between OS 8 and OS X.
    Could someone confirm this with me please? Could this cause some file permission problems?
    I would use OS 8.6 to run my older Adobe Illustrator 8 application and photoshop 6. And then I will boot onto Tiger for everything else. I would switch a few times per day back and forth.
    Basically, is it safe to run Tiger on the same computer that has OS 8.6 installed on it? (I am not concerned about making 8.6 run in the Classic environment because I know that doesn't work - I am refering to having separate bootable installs)
    [1] http://www.unsanity.org/archives/000410.php
    PS I am aware of how to change my startup OS on this particular computer (b&w G3). I would have to have the two OSs on the same volume and launch X by pressing x -key during startup due to the fact that OS 8.6 doesn't have the Startup Disk feature introduced in OS 9. That was an earlier separate discussion that has since been solved.
    PS
    I could choose to instead use my OS 9.2 but I have reserved that OS for another computer unfortunately. However depending on the outcome of this post, I might have to reconsider.

    This is a really difficult issue to resolve! Apple doesn't have much documentation that covers running OS 8 & OS X on the same drive. There are, however, a few things that it might helpful to know:
    1. Repairing permissions with Disk Utility in OS X won't touch user-created files. It only repairs things that have a receipt file, which are created by installers. The unsanity reference explains this; you might want to review that part of the article again.
    2. Disk Utility has a separate repair OS 9 permissions function (accessed in the menus), but AFAIK, this only repairs permissions on the OS 9 system folder "blessed" by the Classic system pref as the one to use for Classic. I doubt this would be useful for the OS 8.6 system.
    3. Of greater concern than mis-set permissions is file system damage. Under no circumstances should you use any disk repair utility on a Tiger drive except those that "know" about Tiger's file structure. This rules out using Disk First Aid from either OS 8 or OS 9, or any OS 8 or 9 third party utilities. (See this Apple document for the details.) I don't know if this also applies to OS 8's 'rebuild desktop' function, but I would avoid it to be on the safe side.
    4. If you do decide to reformat or partition your drive for dual booting (as you mentioned in your other thread), do so only with Tiger's Disk Utility & remember to check the 'install OS 9 drivers' option or you won't be able to boot into OS 8 or 9, even if you have a viable system folder for either on the drive. See this Apple document for more info.
    5. In light of the above, it is well worth getting OS 9 to use with Tiger on your B&W, as long as any older apps you need to run are compatible with it. (There should be no need to use OS 8/9 with text files anyway, since OS X can handle all the old text formats.) In fact, unless you need to use some peripheral that has no OS X driver, you probably will do just fine by using Classic with the old apps, eliminating the need to reboot completely.
    6. If you need to buy OS 9, one inexpensive source is OWC's Mac OS 9.1 - OEM CD. At $35, it is a cheap way to avoid the headaches of OS 8 with Tiger! Note that you can upgrade from this 9.1 version to 9.2.2 for free with Apple's updates available from the Mac OS 9: Available Updates web page.

  • Can I use a 3T disk on a G5 running Tiger?

    I am trying to upgrade the hard drives in my 2004 2 Ghz Dual Processor PowerPC G5 running Mac OS X 10.4.11.  (I need Tiger to run some older apps.)  I replaced the original Maxtor 250GB SATA with a 3T Hitachi Deskstar.  I'm hoping to install a second 3T drive and mirror all my work using RAID1.  I would like to use this machine to drive my Nikon Slide Scanner and manage large archives of TIF and Raw photographic files.
    Since Tiger would not recognize the larger drive, I used Disk Utility from a Leopard DVD to partition the drive into 2 parts: 1T and 1.8T.  These partitions checked out when verified with the Leopard version of DU.  I have successfully copied my applications and files to the smaller partition (I'm using it now), but the Tiger Disk Utility tells me I have problems with the 1.8T partition.  I get the message: "The underlying task reported failure on exit."  I had successfully repaired the partition with the Leopard version of DU ("Invalid file clump size."), but cannot repair it using Tiger DU.
    Questions:
    Is there a disk size limit under Tiger?
    Is it possible that I'm encountering a timing problem with the bigger faster disk?  Is there a different jumper setting I can use?
    Is this likely a problem with the drive itself?
    Is there another utility that I can use with OSX 10.4 that will fix this problem?
    I've searched discussions and boards for the last day or so, and am not finding any answers.
    Help would be appreciated.

    To promote file contiguity and avoid fragmentation, disk space is typically allocated to files in groups of allocation blocks, or clumps. The clump size is always a multiple of the allocation block size. The default clump size is specified in the volume header.
    http://dubeiko.com/development/FileSystems/HFSPLUS/tn1150.html#HFSPlusBasics
    To use Partitions of more than 2.2TB they came up with GUID Partition Scheme, as APM had the 2.2TB limit. Drives also now use Advanced Format...
    http://en.wikipedia.org/wiki/Advanced_Format
    I've read that 10.4.11 is supposed to deal with that, but it's not 100% clear to me if that includes G5 Macs running 10.4.11, or only Intel Macs, or whether there might even be some split between early & late G5s with that capability.
