Will moving from Tiger to Leopard speed up or slow down my Dual 1.25GHz G4?

I'm currently running Mac OS X 10.4.11. If I upgrade to 10.5.8 (which I believe to be the final version of Leopard) do people feel that overall my Mac will run (& feel as if it's running) more quickly or more slowly?
My experience with Macs (17 years worth) tells me that, other things being equal, a newer OS normally slows down a given set of hardware. Also, according to the graphic on this page, the guts of Leopard appear to be very similar to Tiger. However I'm hoping against the odds that in this case Leopard might give me a speed boost.
I can't think of any features that Leopard has that Tiger doesn't that I'd like to use or that I feel I'm missing out on. It's just a possible speed boost I'm after, along with compatibility with the odd utility etc. that requires 10.5 or higher.
My main application usage at the moment is as follows: Microsoft Entourage 2008 (version 12.2.7) for email (although this may change - see my Topic here), Safari 4.1.3 for web browsing (& also occasionally Firefox 3.6.12), iTunes 9.2, QuickTime Player 7.6.4, and also more demanding creative software - primarily Adobe's Creative Suite CS2 (although I'll probably be upgrading to CS3 in the next few months) and occasionally things like Final Cut Pro 5.0.4.
Many thanks.

Leopard makes a few improvements in performance over Tiger especially in the graphics and video area. Otherwise you would not notice any changes in speed.

What are the advantages of moving from Tiger to Leopard?

Hello all,
I currently have an iBook G4 Mac with 1.25MB RAM and a 1.2GHZ processor running Tiger 10.4.11. I was thinking of upgrading to Leopard in order to get the longest life out of my system before I can afford a Mac. Before I take the pluge I'd like to consider what the advantages of the new operating system are, and it seems to me that the additional advantages are not too clear from the official documentation and Apple Store.
My system will not run Snow Leopard from the system requirements that seem to be coming out so I think this would be the best step to keep my Mac going and compatible for new software that I use for student work, which is primarily musically orientated plugin's and software for midi controllers and mixing. Do you think it would be worthwhile upgrading my system and it will be fast enough for efficient use?
Lastly if I do upgrade, what is the best way to install the new system while trying to preserve current applications and folders. Would it be best to use data migration to a external hard-drive and back again, or is there an easier way to maintain the system applications and files.
Thanks,
Robert

See the list of the 300 new features in Leopard and then decide if they are worth it to you.
Whenever I upgrade, I do an "archive & install". It will move your previous system files to a "previous systems" folder and install a new system from scratch. You can also have it preserve user and network settings, which is what I always do. It makes for a very smooth and reliable install with a minimum of fuss.

Will upgrading from Tiger 10.4.11 to Snow Leopard delete programs?

Sorry if this is a stupid question or answered a million times before, but will upgrading from Tiger 10.4.11 to Snow Leopard stop my existing programs (PhotoShop, Office etc) from running? I've got an Intel MacBook but I've never installed a new OS myself, so any tips gratefully received! Thank you.

You will lose the ability to work in any Classic OS applications that ran under system 9.
If I were you, before upgrading do yourself a favor and purchase an external hard drive that you can "clone" your Mac to. If possible, a large enough drive that you can have 2 partitions. In one you would clone your current system and apps. Then after the upgrade, clone again your updated system to the other partition as a emergency backup.
With the clone of your current set up, if need be you can rebbot to it so that you can use any of your "old" applications.

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.

Upgrading from Tiger to Leopard on and external (FireWire) drive...

Hi all,
I'm pretty sure this has been discussed somewhere on the www but after several hours of research, I'm embarrassed to admit I'm ready to call it quits (unless someone more tech savvy than I can help <:o)
I've been running my OS on a WD 500GB FireWire for the past couple of years. Switched to it shortly after realizing that the 80GB HD on my MacBook was insufficient for my needs.
Now I'm getting ready to upgrade from Tiger to Leopard and I've got some issues. Most importantly, when I launch the installer and it requires me to restart my system, I do so through both methods (holding down the "option" key to start up using the external HD and also by just allowing a normal boot under the old drive). In neither situation do I ever get the option to select where I'd like to install the new OS. In fact, when I allow the normal start without the "option" key being pressed, I don't even get to see the option to begin an installation. When I hold down the "option" key, I get the Mac OS X Install DVD screen (directory on the DVD), but it never gets to the point where I can start the installation.
I'm at a loss and getting a little frustrated (which has been my problem since I started with Macs--been a long time PC user and I'm always looking for the difficult way of doing things--so I'm probably just being PC-stupid as usual >;o)
Any assistance with getting me on the path to continued righteousness would be greatly appreciated. Thanks very much in advance!

PS: Despite the fact that I'm PC-literate and Mac-stupid, I've managed to convince almost a dozen people to switch to Mac, simply because I'm hooked and love how the Mac community sticks together and helps one another (and also because I can't stand the Microsoft kingdom!!! <:o)

Insert the Leopard DVD in the optical drive and restart the computer. After the chime press and hold down the "C" key until the dark gray Apple logo appears on the screen. After the installer loads select your language and click on the Continue button.
When the menubar appears select Disk Utility from the Utilities menu. After DU loads select your startup drive's 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.
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.
Continue with the installation process until you reach the point where you must select a Target drive. Select your Target drive then click on the Options button in the lower left corner of the dialog.
Select the Archive and Install option.
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.
Your target drive must have repaired OK when you repaired it. Otherwise do not continue.
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.
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.
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.
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.

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
Gary

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
Gary

Can't find mails anymore after update from Tiger to Leopard

I've just updated my IMac from Tiger to Leopard (OSX 10.5.6).
After opening the Mail program I just see the menu bar (no window for the postbox).
When I open the postbox via the menu bar, the box is just empty. Are my mails gone? Where can I find or restore them?
Thanks for help,
Vanillia

Let's force an overall reindexing via the removal of the Envelope Index. Note the special instructions when forcing the reindexing of IMAP or Exchange accounts in the following:
http://docs.info.apple.com/article.html?path=Mail/3.0/en/14019.html
This will force the reindexing of all the POP mailboxes and all On My Mac mailboxes. With regard to any IMAP accounts if you have any, the practical result of this action of removing the account folder, is that with the IMAP account still set up in the Preferences, Mail will connect to the IMAP server and create a new account folder, and while doing so will index the messages in the mailbox folders of the IMAP accounts on the server.
Keep me posted.

I upgraded my iBook G4 from 384MBytes to 640Mbytes and upgraded from Tiger to Leopard. After a few weeks the HDD failed. New Leopard install reports: "insufficient memory". I need Tiger install disks so I can install

I upgraded my iBook G4 from 384MBytes to 640Mbytes and upgraded from Tiger to Leopard.
After a few weeks the HDD failed. I bought a new disk, installed it and trued to install Leopard, but the install fails reporting "insufficient memory".
I assume the installation requires more memory than the OS actually needs to be able to run.
I need Tiger install CD/DVD so I can install Tiger first and then upgrade to Leopard.

Call Apple Customer Support 1-800-767-2775, provide the Serial Number and specifications of the Mac, and for a reasonable fee, they will supply a replacement set of system discs (if available).
The discs will be for the original version of the OS that was pre-installed when the Mac was manufactured.
You need much more RAM than that.

Do I need to backup my files when upgrading from tiger to leopard?

Not sure if I need to backup all my files before upgrading from Tiger to Leopard (to use a Mac Box Set), have bought a Seagate 1TB FreeAgent GoFlex Home hard drive to back up on. Was told I wouldn't need a WiFi router but have now discovered I would need a dual Ethernet port to be connected to the internet and the hard drive which my Mac mini only has access for one, either the internet or the hard drive. So I ask do I really need to back up before upgrading? or can you get dual Ethernet ports?

Only if your data has any value to you.
If everything works perfectly, you should lose nothing.
If anything goes wrong, it is possible to lose data.
Personally I don't want to trust my data to everything working perfectly so I back it up.
As to the question of dual ethernet ports, you don't need them actually. If you create a LAN with a router then the multiple ports on your router will allow you to connect to both the internet and disk at once.

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,

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.

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.

Lost emails upgrading from tiger to leopard

I lost emails (although mailbox folders are still there, just empty) after upgrading from tiger to leopard. Please help?!

I followed these instructions the last couple of times this happened to me. It works so well that I've made a text file with these instructions:
I got it to work by deleting all the values in the defaults database associated with Mail and the Junk rules. In my case I did the following:
Remove the Envelope Index file (~/Library/Mail/Envelope Index) from your user account.
Launch Terminal.
Copy/Paste this list into the Terminal window.
defaults remove com.apple.mail JunkMailBehaviorHasBeenConfigured
defaults remove com.apple.mail JunkMailHeaderFlags
defaults remove com.apple.mail JunkMailInfoPanelHasBeenShown
defaults remove com.apple.mail JunkViewerAttributes
defaults remove com.apple.mail LastTimeJunkWasVisited
defaults remove com.apple.mail NumberOfMessagesMarkedAsJunk
defaults remove com.apple.mail NumberOfMessagesMarkedAsNotJunk
defaults remove com.apple.mail UseJunkMailHeaderFlags
Watch the rapid execution of the text commands in the Terminal window.
Quit Terminal.
Launch Mail.
Follow the onscreen guides to import your mail and watch the mail database restore itself.
All mailboxes, drafts, etc., should be quickly restored. Mail launches and quits correctly.

I need to upgrade from Tiger to Leopard for Quickbooks 2009; can you point me to some resources that will walk me through the process (and point out any pitfalls)? Also is the product that outfits like Amazon or Buy.com are selling what I need to do the upgrade?
Thanks.

Hi ramonelkalsaw;
The only thing I would add it that while the upgrade process does claim that it will preserve things for you I would add that creating a bootable clone before starting the upgrade process is a good thing. It gives you an easy way to get back to where you were before you started very quickly just in case something goes wrong.

Upgrade from tiger to leopard

can I upgrade from tiger to leopard? can I do it online or should I buy the CD?

can I upgrade from tiger to leopard?
Yes, if the computer meets the system requirements for Mac OS X 10.5. If it meets everything other than the CPU speed requirement, you can still use it, but it can't be installed in the normal way.
can I do it online or should I buy the CD?
You need to buy a retail package. Online purchasing options involve the seller sending a retail package to you instead of providing a download.

Will moving from Tiger to Leopard speed up or slow down my Dual 1.25GHz G4?
