Tiger vs Leopard performance

What is the fastest?
I currently have leopard installed, but am thinking of going to Tiger as I find Leopard quite laggy.
I have a fast HDD, 2GB ram 1.67ghz PPC.
So what do you think?

To piggyback off Peter's advice about Dashboard: after a restart, Dashboard is loaded but darned near dormant, idling at a very low CPU usage level (you can confirm with Activity Monitor). Once you acces a widget, they all become active and start using much more resources.
I found a widget that will shut down the open widgets when you're through with them. Dashboard goes back the same sleepy state it's in after a restart. Really helps considering so many widgts are designed to "phone home" when active, thus using some bandwidth in addition to processor power.
I keep Dashboard on all our modern Macs because there are items I like to use from there. However, they all have the extra shut-down widget for when it's not needed.
The widget is here:
http://www.apple.com/downloads/dashboard/status/dashquit_berenguierduncan.html
I don't think its display of widget RAM usage is accurate but it certainly puts Dashboard in its proper place--a humble servant who only works when beckoned and quietly returns to its quarters when not needed.

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 may be able to install Tiger 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 may be able to install Leopard with 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 needs at least 256 MB of RAM.
Leopard needs 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.

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):

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.

"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.

List of sysctl add/del/changes between Tiger and Leopard

I've ran a quick diff between the sysctl values in Tiger and Leopard. Note: This is from two different macbook's, so some values may be changed due to hardware.
This should give folks an idea as to what buffer sizes, performance tweaks, etc. have been added.
If you're real bored, I guess you could revert everything network related back to Tiger values ... but, yeah, good luck with that. You may break more than you fix.
Most of these you can lookup on-line or in the kernel source to see what they do. Sometime in the next week or so I'll add descriptions if you don't have a network background or src code background.

Hey there,
I believe I'm having the same issue. I'm using Mail.app in 10.5 with a gmail account (IMAP). The issues is that in Tiger we had the IMAP option in the account settings "Advanced" tab to: "Automatically synchronize changed mailboxes." This option appears to be missing, and even more, does not happen in Leopard. What this means is that changes to folders (other than one's that you explicitly open/synchronize manually, will not shows updates in Leopard.
This is especially annoying with the "All Mail" (Archive) folder for Gmail IMAP in Leopard. In order to ensure that your "All Mail" is always up to date, you have to manually open it (to initiate a sync). Otherwise it does not auto update like it does in Tiger.
Thanks,
Shahrum

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.

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.

Tiger and Leopard on the Same MacBook?

I have a MacBook and would like to have both Tiger and Leopard on it. I Googled and found info that did not work for my "newer" machine. I purchased two months ago. I have a number of files that are Tiger only and will not be rewritten for Leopard. Can anyone offer a possibility of doing this for the newer machines!?!?!

To boot two different OS X versions, you need to have each version installed on a different bootable Volume. This can be on different partitions on the same drive, or on different drives, i.e. the internal and an external FW drive.
(Mac OS X and OS 9 can be on the same partition or drive for the older OS 9 bootable machines)
This is very useful when upgrading a Mac to a new OS, then you can perform the installation on a new drive and keep your old drive in tact, allowing you to boot the old and new OS version and access files from both drives.
However, when a Mac ships with a particular OS version, most of the time you can not downgrade to an older OS version.

How Do I Import Playlists From Tiger To Leopard?

OK, I give up. The following falls under the category “It Doesn’t Have To Be This Hard.”
I purchased a new iMac and went with the 24 inch Intel 3.06 GHz Core 2 Duo, 10.5.5. Sweet.
With my previous iMac (G5 Rev A., 10.3.9), I had Tiger 10.4.11 installed on an external HD and used it for my iTunes collection. All was well.
Now, with Leopard on the new iMac, I’m stumped as to how I can import the playlists from Tiger’s iTunes. I’ve imported the music and podcasts, etc. from Tiger but the playlists are empty. I have them listed but all except one have no music in them.
So, my questions (after performing a thorough review of the forums and entering every search term I could think of related to this issue) are these:
1. How do I import playlists from Tiger to Leopard so that I get music and playlists?
2. Where are the playlists stored? I cannot find them using a Spotlight search ( using Leopard), nor are they listed in the iTunes music files. So, where does Tiger and/or Leopard keep them?
3. At least one playlist made it from Tiger to Leopard. Why did the other playlists arrive but w/o music in them?
4. Is the problem I have described a common one? If so, why is there no easy fix for it. Or perhaps there is an easy fix but I’m too blind to see it.
Anyone with answers is encouraged to reply. I’ll sign off as “flyboy01” but in reality I’m “Stumped!”
Thanks in advance,
flyboy01

Just so you know, the difference in the version of the operating system has no bearing here as you would have experienced the same issue going from account to account on the same computer because you performed an incomplete iTunes transfer. As you inquired about where playlists are located, I will give you a complete break down of iTunes database structure as well as the proper technique for transferring your library.
_*INSIDE iTUNES*_
*iTunes Components: The Library and the Database Table*
The term library gets thrown around quite a bit when people discuss iTunes, but what you see in iTunes denoted as your libraries (e.g., music, podcasts, TV shows, etc.) is actually just a reference to your actual media library. iTunes is essentially a database package, just like your local public library’s computer-based card catalog system; the difference is that the content is electronic and owned by the user so you can also directly access the content through iTunes instead of having to go and (physically) retrieve it. Your actual library is the collection of media files you have stored on your computer. If you think of it in terms of the real world, your media files are the virtual equivalent of the books, periodicals, microforms, etc., in a real library and the folder or volume in which those media files are contained is the library.
While iTunes will allow you to add media to its library (iTunes library interface) from anywhere on any volume attached to your computer (e.g., branch libraries), iTunes generally expects your library to reside in a single folder (main library). In iTunes that folder is referred to as your iTunes Music folder and by default it is a folder named iTunes Music contained in your iTunes folder (~/Music/iTunes). The music folder can have any name and be located anywhere on any attached volume as long as you inform iTunes of where it is located by changing the iTunes Music folder location in the Advanced tab of iTunes’ preferences.
How you organize music within your music folder is unimportant, but iTunes must know the location of the (root) music folder in order to properly access the media files contained within that directory. The reason for that is because once you have defined a music folder location, or leave the default, that location is where iTunes will automatically place any new content that you add to iTunes’ library. Keeping the location of the music library straight is most important to iTunes users, such as myself, that keep their actual library on a separate volume from the system volume where the iTunes folder is located.
When iTunes uses the term library, it is actually referring to its database table file. Properly designed databases, particularly those that are scalable and that allow records (database entries) to be found or visually organized via multiple keys (metadata), as iTunes does, consist of two basic parts: the database, or source data (records), and the index table(s). In iTunes your media files are the records. Along with the actual media content, those files also contain a number of tags that provide a range of information about that particular media file (e.g., artist, song title, movie title, album, year, etc.).
The database table is the iTunes Library file located in your iTunes folder. That file is actually what iTunes references the vast majority of the time when you are browsing your collection. The table contains metadata about all of the media files in your library and it is that metadata that is displayed in iTunes when you browse your library. When you play content or edit tags, then iTunes directly accesses the files in your library. The table also contains your playlists and playlist folders, so that is the reason that Spotlight would seem to not find them on your computer’s hard drive; Spotlight most likely did list ‘iTunes Music Library.xml’, as that file is an XML version of iTunes database table.
If you copy the iTunes Music Library.xml file to the desktop on your old computer and open it, you will see the basic structure of the table. The first group of entries are the definitions of your media files—the code between the <dict> and </dict> tags—and contain the metadata that is displayed in iTunes and by which you can search and group music in iTunes various views. The definitions also contain metadata defining the location of the media file, if the track is enabled (checked) or disabled (un-checked), the (iTunes) track ID, etc.
If you scroll toward the end of the XML file, you will see the definitions of your playlists and playlist folders as well as some occasional data blocks that look like gibberish. The latter is the text representation of the binary code that defines the criteria for smart playlists. On thing that you will notice about the playlist definitions is that they do not contain detailed track info or metadata for the songs contained within the playlist(s). iTunes is a relational database, so the playlists do not contain any actual data, but instead a list of indices (pointers), the Track IDs, to the definitions for each track you have in your playlists. The definitions listed in the first part of the XML file also contain only a subset of the tracks ID3 tags. The definitions only require metadata for information that is relevant to permitting you to browse and organize your library in iTunes’ interface. In the track definition, the Location metadata is an index and points to the actual media file where the complete set of ID3 tags, as well as the actual media content, reside.
While your media resides in your music folder, the library structure you create in iTunes is actually a simple, albeit long, table stored in a separate file. Another component of iTunes is the artwork database kept in the Album Artwork folder. The Album Artwork folder contains a complex folder tree structure with proprietary .itc files at the leaves. I do not know what the exact structure of the .itc files is, but they play a role in storing image info for the various graphic-based views in iTunes (e.g., CoverFlow). Also, any songs you purchase from the iTunes Store will have the cover art stored in the Album Artwork folder; images that you add manually are stored in the actual media files.
*Transferring Your Library to a New Computer*
Now you see that there is more to iTunes than just your media files. Thus, if you want the playlists that you spent time building to migrate with your music collection simply copying the music folder to the new computer is not going to result in what you want: a complete transfer of the library you dedicated time and energy into organizing. When you transfer music files to a new computer iTunes builds a new library around that content and the only playlists that will be present are the defaults tha come with iTunes; your user-defined playlists will not appear on the new computer if you have not transferred the database table.
In order to successfully transfer iTunes to a new computer you need to move your library and everything that was built around that library. To perform a complete library transfer you need to follow this procedure:
1. *Consolidate your library* If you know for a fact that all of you media files are contained within a single root directory (e.g., iTunes Music), then this step is not necessary. If you do not have the preference to “Copy files to iTunes Music folder when adding to library” enabled, then there is a good chance that you will have orphaned media files and should consolidate your library just in case. To perform library consolidation go to Advanced > Consolidate Library (iTunes 7.x) or File > Library > Consolidate Library (iTunes 8).
2. *Transfer your database* Replace the default iTunes folder on your new Mac with the iTunes folder from your old Mac by transferring the entire folder. When asked if you wish to replace the existing iTunes, do so.
3. *Get the media library* If you keep your music in the default iTunes Music folder contained in the iTunes folder, then you have already performed this step. If not, transfer your music folder from you old Mac to wherever you wish for it to reside on your new Mac.
4. *Set up iTunes* Unless you already started modifying preferences in iTunes on the new Mac, when you launch iTunes you should see your music library just as you did on your old Mac.
a. If your library is in the default location, ~/Music/iTunes/iTunes music folder, iTunes will begin rebuilding your library after it launches. Once that process is completed, you should see your library with playlists and folders intact.
b. If your library is in an alternate location, you will see an empty library, but you should see your playlists and folders, albeit filled with broken links. Go to the Advanced tab in iTunes’ preferences and change the location of the iTunes Music folder to the location of your transferred music library. iTunes will begin rebuilding your library from the alternate folder. Once that process is completed your library should be just as it was on your old Mac.
5. *Keep your library consolidated* To insure that any new media that you add to iTunes stays with your main library when you add content to iTunes make sure the “Copy files” preference is enabled. If the “Copy files” preference is disabled then any content that does not come from the iTunes Store or ripped CDs that you add to your iTunes library will remain in the location where the content was originally placed.
Hopefully this helps you better understand how iTunes works and why simply transferring your media files results in a loss of your library’s structure.

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.

What will I lose when upgrading from Tiger to Leopard

I am relatively new to Macs and am concerned about what I will lost if we upgrade out Mac mini server from Tiger to leopard. There was a time when new Apple computers were not backward compatible, certainly Microsoft upgrades always have issues. Thus I have fear for performing an upgrade from Tiger to Leopard on our server without knowing what we are in for.
I looked at some of the discussion threads here and elsewhere. I see a lot of minutiae but none that would be an issue to me. Then again, no one seems to put out a publication (including/especially Apple) that say here are the possible drawbacks.
I guess our biggest concern in our existing data. Are there any types of document formats that we will no longer be able to read?
I assume Office, Photoshop and those types of programs will be fine as surely the publishers have issues the necessary updates. Is that correct?
Are there any mainstream issues that could come as a surprise to us and present serious problems?
Thank you,
Robert

I guess our biggest concern in our existing data. Are there any types of >>document formats that we will no longer be able to read?
Only if the applications which open those documents run in Classic.
And only if you do not have another program that can open them.
for example, Filemaker...I used FM5 (classic app)...OSX versions of FM were both overkill for my needs and cost prohibitive, so I never upgraded.
Lost access to all those files.
Fortunately, I was able to download a demo of FM9, open the files, export them to XLS format, then open them in either excel or numbers. Of course, lost the database functionality, embedded images were no longer there, and calculated fields failed, but at least the data fields converted.
The issue in photoshop, from what I understand, is saving to a network drive.
(possible file corruption)
Save locally, then copy to a network drive, and pshop should work fine.
Are you already on Intel, or are you on PPC? you may find some other quirks if you are also upgrading to an Intel based system.
Things like QT and browser plugins that are not Universal binaries.

Upgrade to Tiger or Leopard Possible or Desirable?

Hi:
We have an old PB that I brought out of storage to give to my son. Details on the machine are below.
Is it possible, and if so, is it desirable to upgrade this to Tiger or higher?
If so, could I just buy a copy of Tiger on e-bay, or does the version of Tiger that one buys have to be tailored to the hardware?
Thank you!

That Mac will go to Tiger or, if you wish, Leopard. Yet it's unlikely to be worth the time, trouble, and money to upgrade that machine. At the very least, you'd want to max out the RAM for peak performance and get a new battery (if you can find one from a reputable vendor), and then of course there's the not insignificant cost of retail discs of Tiger or Leopard to perform the upgrade. Retail discs are black; they're not the gray ones often sold on eBay to unsuspecting buyers who learn too late that gray discs of the OS are model-specific and can't be used to boot/upgrade their older machines.
When you can get a newer model used MacBook for as little as $150 -- here, http://www.macofalltrades.com/Refurbished-Used-Apple-Laptops-s/5.htm?searching=Y &sort=1&cat=5&show=300&page=1, for instance -- it's usually not cost effective to resuscitate and upgrade an old PowerBook.

UPGRADING TO EITHER TIGER OR LEOPARD FROM PANTHER 10.3.9

Dear gentleman
i have  doubt and i would like to have  your experienced point of  view><
if i upgrade from my PANTHER 10.3.9 to either Tiger or Leopard><
will i have same background failures i am having ><
or the new
upgrade os ( tiger / leopard)  software will give me a new healthy sistem , clean from all the recent Kernel Panic iam having since more then a week!!!??????????????????
i have been reading that a  clean installation of the same OS IT IS BETTER THEN A NEW UPGRADING ,
because the clean installation it will let out all the failures and so nothing of the >old troubles ( kernel panics and so others broken files and so on ) would be present effect my pc in that case!
is that truth????????????
what  you think ??????????
sincerely regards
wish a good week to all of  you

gio,
If you PowerBook G4 meets the Tiger System Requirements, or the Leopard System Requirements, and your Hard Drive is not failing, then you can perform an Erase & Install of either system.
That should make your Mac operating system, once again stable.
But if the Kernel Panics are being caused by incompatible peripherals, Hardware, or Third-Party applications or programs, once you reintroduce those items, you will once again have Kernel Panics.
If you do an Erase & Install of your original operating system, or Panther 10.3.x, the same would be true.

Upgrading from Tiger to Leopard on a G5 Dual processor early 2004 version

I am about to upgrade my OS from Tiger (10.4.11) to the newest version of Leopard on my Dual G5 PPC. I have an ATI Radeon X800 XT video card as well as a third party PCI firewire card added. 3.5G of RAM.
Should I expect any bumps or issues when upgrading? Also, will my system perform the same, slower or faster after install?
I am a heavy user of Aperture, Photoshop as well as Final Cut Express. I will be installing the newest version of Fotomagico once 10.5 is set up.
Any advice is greatly appreciated.
Pete

You should verify that all your critical software can run under Leopard or that there are upgrades available. Check with which version of Leopard the software is known to be compatible, and don't install a later version of Leopard.
Otherwise I suggest reading this:
Essential Steps Before Updating OS X!
Please do things right before updating OS X in order to avoid problems.
A. Repair Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger and Leopard.) 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 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) 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. Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means your backup drive (should be erased first.)
Source means your startup drive or volume.
C. If you are installing a new version of OS X such as upgrading from 10.4.x to 10.5.x, then I suggest you do the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
D. Download the Standalone Combo Updater from Apple.
Be sure you quit all running applications and disconnect all peripherals (except original keyboard and mouse) before running the installer. When the installer is running do not use the computer in any way other than to respond to an installer dialog.
Install the update by double-clicking on the installer package icon. When the installation is completed Restart the computer. Your computer will boot twice - this is normal. Upon completion of the update use Disk Utility to repair permissions. Not all permissions will seem repaired. You will get spurious reports regarding permissions related to iTunes, Front Row. These can be ignored. They will appear every time you repair permissions.
Following these basic steps should prevent most if not all updating problems. Note that if you have unrepairable disk problems reported in Step A then DO NOT update your system until those problems are resolved.

Shes slow! Tiger or leopard and whats acl?

HI sorry guys but im not very techy so i dont know if ill explain myself properly here but here are my powerbooks details first anyway.
Shes about 3 years old.
Model Name: PowerBook G4 15"
Model Identifier: PowerBook5,6
Processor Name: PowerPC G4 (1.5)
Processor Speed: 1.67 GHz
Number Of CPUs: 1
L2 Cache (per CPU): 512 KB
Memory: 512 MB
Bus Speed: 167 MHz
Boot ROM Version: 4.9.1f3
System Memory
Free: fluctuates between 85 and 95 MB
Wired: circ 96MB
Active: circ 256MB
Inactive: Circ 68MB
Used: Circ 421MB
Supposedly overall ive 20 GB free.
Dont know if ye need all that but anyway my problems are as follows.
Everything from programs opening to scrolling down or even highlighting a menu is painfully slow.Im seeing the beach ball constantly.
I cant open anything while burning a disc.
I upgraded from Tiger to Leopard recently hoping it would help milder versions of these problems but its just become worse. Should i just go back to Tiger?
Ive run Disk Utility and usually it comes up with a few things that it fixes but today it came up with a list a mile long filled with lines of
ACL found but not expected on "System/Library/User Template/da.lproj/Library/Audio".
ACL found but not expected on "System/Library/User Template/ko.lproj/Library/Fonts".
ACL found but not expected on "System/Library/User Template/zh_TW.lproj/Public".
ACL found but not expected on "Applications/Utilities".
ACL found but not expected on "Applications".
for example. Someone said i could have a virus! Is that possible on a mac?!
Any advice would be great!
Thanks guys.
Gemma.

Hi, Gemma. You can ignore all the ACL messages, according to this Apple article:
http://support.apple.com/kb/TS1448?viewlocale=en_US
It has nothing to do with a virus.
Your computer (which is Aluminum, not Titanium) has the bare minimum RAM for Leopard, and that's hard on performance. If you had performance issues while you were still running Tiger, upgrading to Leopard (which requires twice as much RAM) was not the way to resolve them.
Have a look at these two FAQ articles and try the tips provided in them:

Clean Install of Tiger or Leopard on PPC Mac Mini?

I have an older PPC G4 Mac Mini (the last one Apple made before they went Intel).
Earlier this year I bought an iMac and transferred everything of interest from the Mini to the iMac. I would now like to wipe-clean the Mini and re-purpose it.
So, my question is in 2 parts:
1) The iMac came with OSX Leopard and I purchased (and installed) OSX Snow Leopard. Can I use the OSX Leopard disc that came with the iMac to install Leopard on the PPC Mac Mini?
2) If I can technically do #1, would I want to? My think is that the OSX Tiger that came with the Mini is a PPC binary while the OSX Leopard would probably wind up being a universal binary. Would this adversely impact performance?

1) The iMac came with OSX Leopard and I purchased (and installed) OSX Snow Leopard. Can I use the OSX Leopard disc that came with the iMac to install Leopard on the PPC Mac Mini?
No. The copy of Mac OS X that came with the iMac is licensed only for use with that system, even though you've upgraded to Snow Leopard.
In addition, it's probably only going to work on an Intel-based Mac and won't even install on your PPC mini. The code may be universal but the installer is probably written to only work with the iMac the disk came with.
If you want Leopard on the PPC mini, you need to purchase a retail copy of Leopard. There should be no performance impact; in fact you may find that Leopard runs a bit faster than Tiger. Leopard will take up a bit more space on the hard drive, though, than did Tiger.
Regards.
