Upgrade from panther

I would like to upgrade I have an Imac OS X G5 version 10.3.9
I would like to upgrade to tiger of whatever newer version that I can .
How do I go about this?

Hi mangonew!
Some additional and possibly repeated info;
If your Mac meets the Leopard System Requirements, the Full Retail Version, of the Leopard Install DVD, can be purchased at The Apple Store (U.S.), Apple retail stores, Apple resellers, and some Online vendors.
If you know what to look for, a Full Retail Version, of the Leopard Install DVD, can be purchased, sometimes less expensively, at some online Apple retailers, Amazon, eBay, FastMac, HardCore Mac, etc.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.
Leopard is on DVD.
The disc should look exactly like the images in the above links, and not say Upgrade, CPU Drop-in DVD, or "This software is part of a hardware bundle purchase - not to be sold seperately." on it.

Once Leopard 10.5.x is installed, you can use the Mac OS X 10.5.7 Update.
You may also find this Leopard Installation and Setup Guide PDF useful.
The posted RAM System Requirement is the bare minimum.
For optimum performance, more is recommended.
As a precaution, before upgrading the OS, you should create a backup of the entire system, or at least, any data you do not wish to lose or corrupt.
In addition to the Archive & Install procedure, there is also a Simple Upgrade, or an Erase & Install option.
Review the info here About Installation Options.
Specifically; "About Upgrade to Mac OS X
Upgrading to Mac OS X takes a little longer than installing it on a volume without Mac OS X, but it is the least intrusive way to install--most of your existing settings and applications are left untouched during an upgrade. In other words, you won't have to configure a lot of settings afterwards."

Upgrading from Panther 10.3.9 to Tiger 10.4.3

My brother has a 17" 1.8 IMac and wants to upgrade from Panther 10.3.9 to Tiger 10.4.3 so he can use Aperture, Apple's new software. Since I have always helped him in the past with his upadates, I prefer doing clean installs by reformatting the hard drive before doing a major upgrade like the aforementioned. Is this the preferred method or should I attempt to install over Panther without reformatting? I'm rather reluctant to go to 10.4.3 based upon the number of negative experiences reported by people who have done so, but if he wants to use Aperture, according to the system requirements needed to run it, he has to perform this update. What recommendations do any of you have for making a safe migration from 10.3.9 to 10.4.3? In other words, what is the best and safest method of updating?
G5 2.3 Mac OS X (10.4.1)

Tom,
Don't forget this forum is the hospital ward. Don't let the preponderance of bad reports make you think an update is bad. These are usually cases where people haven't taken the proper precautions while updating which should always be taken.
Mac OS X doesn't technically have a clean install option. For reasons why I say not, see this user tip:
http://discussions.apple.com/thread.jspa?messageID=607614
The best method of upgrading depends on how well the machine is functioning in 10.3.9. If it has sufficient space, sufficient RAM, has not had any kernel panics, the following sequence of steps is recommended:
1. Backup your data.
2. Make sure all your hardware and software has compatible drivers for the operating system you are going to. Verify all the applications you are going to use are updated.
3. Dismount and disconnect all third party peripherals.
4. Upgrade and install to 10.4 with a retail 10.4 installer disk. Do not use a system specific disk on a different machine. Buy the box family or single user pack from an Apple software reseller.
5. Repair permissions with Applications -> Utilities -> Disk Utility
6. Run the 10.4.3 combo update:
http://www.apple.com/support/downloads/macosxupdate1043combo.html
7. repeat step 5.
Do steps 1 and 5 before and after any update as a general practice in anycase. Application installers often have a tendency to want to mess with permissions and sometimes don't put them back causing problems later on.
Now if you are having issues launching specific programs, or programs unexpectedly quitting now, or 4 language screens those need to be isolated before you update.

Why upgrade from Panther to Tiger on G4 iMac?

I have two iMacs. I use a G5 recently upgraded from Panther to Leopard 10.5.5. My wife has a G4 with Panther 10.3.9.
Now that I have Leopard I have a Tiger install license available.
Are there good reasons to upgrade my wife's G4 to Tiger?
She uses it heavily for e-mail, internet, and MS Word.
She's networked to my G5 through Airport and we use printer sharing and file sharing.
Her G4 works great, but I'm wondering about security issues.
Comments?
-Bob

Correct me if I'm wrong but I think Apple is still releasing Security updates for Panther too, isn't it?
I think some of the Panther software is starting to show its age limitations for Internet capabilities, and things like iTunes for all the new iPods, etc. On one hand if you're not actually having problems then my feeling is an old computer best runs software designed for it. On the other hand I am not sure you would lose any functionality if you did upgrade. I think most Panther applications run on Tiger, the system requirements are pretty similar. It's not like when you upgrade to Leopard that you suddenly lose Classic support and it requires (demands?) a faster processor. From my personal perspective upgrading to Leopard really makes a big difference in capabilities both ways and may even be a negative upgrade if you run old software the way I do. Upgrading from Panther to Tiger didn't have any downsides and had several upsides in terms of software is still being brought out for Tiger.

Upgrading from Panther to Tiger. Is it worth it?

Hi there. I have been debating this in my head for quite some time. It is worth upgrading from Panther to Tiger? What are the benefits?
Thanks,
dave

Hi dave!
If you do decide to upgrade, Tiger is available for purchase at The Apple Store (US).
Jaguar and Panther, are no longer available directly from the Apple Online Store, as Tiger 10.4.x is the most up to date OS.
A Full Retail Version of the Tiger Install DVD, can be purchased rather inexpensively, at some online Apple retailers, Amazon, eBay, AppleRescue, (as cornelius mentioned) etc.
Be sure not to purchase grey, upgrade or machine specific CDs or DVDs.

Need to upgrade from Panther

I need to upgrade from Panther so that I can sync my ipod but I also use classic Mac os 9 for some programmes. If I upgrade will I loose the ability to use these programmes or can I still run classic. Help someone.......also I am not completely confident so be gentle....I need clear answers. Please help.

Hi.
If your machine meets the system requirements for Tiger, then you can install it.
Tiger supports the Classic environment (runs OS 9.2.2), so you'll be able to use your classic programs.
Good Luck.

Having problems upgrading from Panther to Tiger

Hi there!
I'm new to this place, but very desperate to find answers. I have been trying to upgrade from panther to tiger for the past week and have gotten a mess. I have to restore my old panther system after a panic kernal while trying to install tiger. I have tried to upgrade, install and archive and erase and install tiger and the same keeps happening: after 30-30% installation of essentials, I get a "try installing again" message and immediately goes to a blank blue screen. I have to reboot from my eDisk on the external hd and re-install my old system. I've done EVERYTHING I can find on the web and in the install suggestions. Everything has been updated (firmware, sofware, etc.), I tired disconnecting external devices except the keyboard and the external dvd I need to install and still the same thing...over and over and over!
So, now I'm down to the fact that I need to install CDs (internal) instead of DVD off the external drive. However, when I went and downloaded the form for the exchange the Tiger versions listed (MA453Z/A, MA454Z/A) do not coincide with the version I purchased (M96397/A). So I'm trying to figure out what this version is that I purchased and if it has anything to do with my big install mess!
So, any ideas out there? Glad to hear your input!

Call 1-800-MY-APPLE WRT media exchange program and the DVD version you have.

Leopard Upgrade from Panther Forgot Mail Messages

I just upgraded from Panther to Leopard. My iPhotos, Word documents, Bookmarks, everything except email messages made it thru the upgrade and are accessible. My problem is that although all of the Mail user settings are fine, and I can send and receive mail, my inbox, sent box, etc. are empty. Do I have any hope of seeing the contents of them again?

It seems Tiger lost my Mail files. I restored from backup, then started Mail again. It imported in less than 1 minute, then started up normally.

Upgrade from Panther Server with Raid1

Trying to upgrade from Panther Server with software Raid1. Upgrade fails with "Could not prepare disk". I'm guessing it has to do with the RAID1? I need to upgrade and not do a clean install.
Could I upgrade to tiger server first?

Wow, Panther server. Ah the memories... Anyway, what you are running into is an issue with the actual Apple RAID software versions. If you run this command:
diskutil checkRaid
You should see in the result:
Apple RAID version: 1
That is your problem. Tiger and Leopard will only install on Apple RAID version 2 which was introduced in Tiger. But, all is not lost. Apple has provided a method to upgrade the RAID version without a break and a recreation. Again, using diskutil, run this command to see your options:
diskutil convertRaid
You will get:
Convert a 1.x RAID set (Mac OS 10.3 Panther or earlier) to a 2.x RAID set.
The filesystem must be mounted and resizeable (i.e. Journaled HFS+).
Ownership of the affected disk is required.
Example: diskutil convertRAID /Volumes/RAID
If the name of the volume is Data, then diskutil convertRaid /Volumes/Data should provide the fix you need.
Boot from your Leopard install media and then before attempting to install, open the Terminal and use the command above. Provided you formated as HFS+ journaled you will be fine.
*Make sure you have a backup!*
Oh, and if this fails, then run a diskutil list and hope that you did not install the OS 9 firewire drivers. If you did, then nuking and paving is likely your only option. In that case, I would suggest a clone, then a Raid break, then a creation of a new RAID set, then a restore, then an upgrade.
Again, make sure you back everything up. Be ready to revert back to your clone. Stop all services before upgrading. Export all users and groups. Just be safe. Panther to Leopard can be a tricky upgrade. If you are using MySQL, do a dump before attempting.
Hope this helps. Backup first. Backup many places.

Upgrade from Panther to Leopard on PowerBook G4

Hi-
I just bought Leopard (for $129 directly from apple) and am interested in knowing the steps I would need to take to upgrade from Panther (10.3.9) on a PowerBook G4 with the following specs:
Machine Model: PowerBook G4 17"
CPU Type: PowerPC G4 (1.1)
Number Of CPUs: 1
CPU Speed: 1.5 GHz
L2 Cache (per CPU): 512 KB
Memory: 512 MB
Bus Speed: 167 MHz
Boot ROM Version: 4.8.4f1
I have 11 GB of disk space available.
Do I have the correct system requirements to make this transition seamlessly? Anything else I need to get?
Thanks!

What's the difference between getting an external hard drive vs. the card? I'll definitely go with 160GB to be on the safe side.
See my reply in your other thread.
I keep reading that Archive&Install is giving people problems. Given my situation, would you recommend Upgrade or Archive&Install or Erase& Install?
I'm running Tiger and did not know that A&I was giving people problems on Leopard. If that's the case, I would definitely do the Upgrade (if that is an option like it has been on previous OSX installers).
My main thing is that I'm going to need to keep Office 2004 (which I learned should work on Leopard).
Given that, use the Upgrade method.
Unless... this may sound silly, but can I save it on disks or something? (I don't have the original install disks anymore).
That's not silly at all, and with some applications it will work. I do not know if that's the case with Office, but I would recommend against it. OSX often needs to "weave" parts of an app into itself via the installation, and copying the actual app will not do that. If you have a disk image of the installation disc, that's a different story, and it will copy/work fine.
Also, when I do the backup (via Super Duper?), where does all the stuff end up living? If it's on my hard drive, doesn't that get taken away when I replace it with the newer/bigger one?
I use SD and think it's the best cloning app out there. You need to save it on an external source, otherwise you're correct, it's still "living" on your PB's HD, and if you erase that HD or something happens to it, all that data is gone.
In your situation, I would consider either an external HD or an enclosure. With an external, you'll be able to use if for backups, which would be a very good idea if you value your data. 300GB and even larger can be found for under $100. I'd recommend a FireWire model, so you can then boot your PB from it if you want/need to.
If money is an issue and you choose not to backup (a bad idea, as all HDs eventually die), you may get an external enclosure. Install the new HD in it, SD/clone your PB's internal HD to it, install the new HD in your PB, and you're good to go. 2.5" enclosures can be purchased for under $10.

Upgrading from Panther to Leopard tips?

Hi, I'd like to upgrade from Panther 10.3.9 to Leopard, ideally the newest version. I have an I-book G4, 1.33GHZ, currently 512 MB RAM and 30.98 GB available disk space.
First question, is 512 RAM enough, or would it be important to get additional RAM for best performance? I think the most I could upgrade to with this computer would be 1.25 GB RAM. Or would it be better to get Tiger instead? What's the worst that could happen if I run Leopard with only 512 MB RAM? Computer slowing down? I would mostly use it for web surfing and writing with Word 2004, so nothing complicated. Thing is, I wouldn't want to spend too much money on this old computer, and more RAM would be another 30$ at least.
Also, is there any upgrade version that might be cheaper to buy than the full retail version? If so, what is it called? If I get the full retail, are they all the same and should I basically be safe with any disk that has the large "X" on it (as opposed to the gray disks that might only work for specific computers)? Not all sellers offer the whole box, which is fine, I really just need the disk, but I want to make sure I'm getting the right thing.
Do you know of a good place to get Leopard for a good price? Is it generally safe to buy a used disk? I would only need it for this one install, don't care if the disk is dirty, as long as it works.
I still have the Leopard disk from my I-mac, is there any way to install Leopard from that disk, or is full retail the only option?

Leo uses more resoueces, especially Video card relaed...
Tiger Requirements...
To use Mac OS X 10.4 Tiger, your Macintosh needs:
    * A PowerPC G3, G4, or G5 processor
    * Built-in FireWire
    * At least 256 MB of RAM (I recommend 1GB minimum)
    * DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
    * At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools (I recommend 20GB minimum)

I still have the Leopard disk from my I-mac, is there any way to install Leopard from that disk, or is full retail the only option?
Sorry, no, it's Intel & machine specific.
main thing for her would be access to internet (being able to watch basic videos online, mail, search, see all photos on a website.
In the end, not much differences as far as that, both are outdated... but I use both daily on the Internet.
Do you know if the old AOL software would work with either Tiger or Leopard? My mother still uses that and is used to it, although I might be able to get her to just check her e-mail on Safari in exchange for better internet access.
No idea, but AOL became irrevelant decades ago, Apples Mail App can be setup in 10.4/110.5 to access most anything, & theres better/safer Browsers in eithere OSSX...
TenFourFox is the most up to date browser for our PPCs, they even have G4 & G5 optimized versions...
http://www.floodgap.com/software/tenfourfox/
I'd avoid vesrion 24 though, as it no longer supports plug-ins like Flash.
SeaMonkey seems pretty fast also, with many options...

Might also look into iCab & OmniWeb versions.

Be carefull when upgrading from Panther to Tiger

If you choose to upgrade from Panther to Tiger by using the Erase and install option on the Tiger DVD install disk, your XServe RAID won't mount. The problem seems to be that the driver for the RAID won't be updated in the process.
The solution for me was (by advice of Apple Support) to reinstall Panther. My RAID came up fine and I then did a upgrade to Tiger using the update and install.

Mattur:When I restart to install the OS, it goes into a Kernel Panic and tells me to restart.I take it to mean that you mean you put the install disk and open it and at the prompt you restart, and it goes into the kernel panic. I notice too that you sayI can reinstall Panther with the disk the computer came with , but I can't install Tiger..In other words there is a problem is with the Tiger disk.
Are you using a Full Retail Version of Tiger? Computer specific versions or update versions will not work.
If you are planning to install Tiger check out System Requirements to be sure your computer complies.
Good luck.

Can I get Tiger cheaper by upgrading from Panther?

Hi, I was wondering if I could get Tiger cheaper by upgrading from Panther. Is there such an option? I would prefer it as I am going to buy new system soon but I need tiger for next few weeks but don't want to pay the full amount. Any suggestions?

No you can't.
The price for the Tiger retail install package is the same regardless which OS X version you are upgrading from.

Can I upgrade from Panther 10.3.9 to Leopard 10.5.2?

I have a Powerbook G4 running 10.3.9. Can I use the OSX 10.5.2 disks from a newer MacBook Pro to upgrade the G4? I tried but a message comes up saying 'you cannot install this software on this computer' but I'd like to know why.

Limnos is correct. Also, note, the Find File system of 10.5 is much weaker than 10.3.9 for locating files quickly by name. Though if you find files mainly by content, then it is better to have Spotlight. See this thread on how difficult it is to work with Spotlight based systems:
http://discussions.apple.com/thread.jspa?threadID=1861415&start=0&tstart=0
Amnesty offers Dashboard Widgets without Tiger or Leopard:
http://www.amnestywidgets.com/WidgetBrowser.html
Launchbar offers almost the same facilities as Spotlight without getting rid of the Find File in the Finder that is faster for simple find by name file finding:
http://www.obdev.at/products/launchbar/
Maybe this is an opportunity to decide if you really want to upgrade that machine to Leopard or Tiger, or just stick with Panther. Unless you have some software that is Mac OS X 10.5 or 10.4 only compatible, I see no reason to upgrade your Panther machine to Tiger or Leopard. Furthermore, Upgrading to Leopard will disable the Classic environment, unless you add an Firewire external hard drive with 10.4.11 or earlier, or erase and partition your hard drive to have 10.4.11 or earlier on it.

Upgrade from panther to tiger

hi,
i have MacOS 10.3.9 installed on my dual 2GHz, Power PC G5 [512 MB DDR SDRAM].
The operating will not upgrade automatically from web.
i would like to upgrade to panther.
do i need a software disc to do this?
if so does it matter which version of panther i upgrade to?
do i have to upgrade to 10.4.1 first?
thanks!!!

You need to buy a retail Tiger disc. They are either 10.4.0 or 10.4.6, but either will work. Software update can then bring it up to 10.4.10 in one step.

Import Address Book after upgrade from panther.

Hello folks,
A friend of mine recently upgraded to leopard from 10.3.9.
Made backups but can't import her old addressbook files.
The way i told her to do it is just to take the addressbook folder from 10.3.9 and replace it in Users > library > application support in Leopard. This has always worked in 10.4 or from 10.4 to 10.5 but this time it wouldn't.
Any idea's ? She can't go back to Panther and needs those address cards.
Thanks for the help
Jay

I figured it would be the same as after an upgrade from Tiger, so i just copied the folder out of Application Support :/
Now that Panther is gone there is no way to go back and export it to vcards or archive anymore.

Upgrading from Panther to Leopard

Hello,
I wanted to upgrade my Powerbook G4 from Panther to Leopard. Was told I needed to upgrade to Tiger first then to Leopard. I bought the Leopard installation CD and will be using the Tiger installation CD that came with my MacBook. Am I good to go? I already enabled the "root" user and is trying to back up my files (which I have another problem with --- been getting error messages such as 1.) "One or more items can't be copied. Do you want to skip them and copy the remaining items? 2.) You cannot copy the item "Icon" because the name is too long or includes characters that the disk cannot display."
Would very much appreciate any help I could get =)
Many thanks!

As already mentioned you do not need to upgrade first to Tiger. In any event you cannot use an Intel version of Tiger on a PPC Mac or vice-versa. Fortunately, you can upgrade directly to Leopard from Panther or you can do an Archive and Install which is what I would recommend:
How to Perform an Archive and Install
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.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
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.
DO NOT ENABLE THE ROOT USER!! It is not recommended nor necessary for backing up your data. Copying files is not how you do a proper backup. Read the following:
Basic Backup
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):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Intego Personal Backup (Commercial)
9. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete FireWire drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.
Note that before doing your backup you should do the following:
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 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 shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (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.
