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.

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

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

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

Can I run Tiger and Leopard on the same computer

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

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

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

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

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

AI have an iPad and iPhone but am stuck with Tiger and Leopard. Will I stir be able to get my email on my PowerBook if I after I upgrade to iCloud? I don't have the cash to upgrade the mac right now.

I have an iPad and iPhone but am stuck with Tiger and Leopard on my old powerbook G4. Will I still be able to get my email on my PowerBook after I upgrade to iCloud? I don't have the cash to upgrade the mac right now. Just wondering what my email options are. Thank You.

You will be able to get your mail on the PowerBook. The calendars (iCal) will not sync; any events added to iPad and/or iPhone will not sync with the Mac but will sync with each other (that is: the mobile devices which are on iCloud). My MacBook Pro (Lion) and iPad2 (iOS5) sync fine; I still get my Mail on iBook G4, MacBook Pro (Snow Leopard) and iMac (Snow Leopard).

Droplet Script used to work fine in Tiger and Leopard, now doesn't

Hey everyone,
I'd like to apologize in advance, I'm not really good with AppleScript and was only able to create my droplet in the first place by changing little bits of a Droplet example script I found on the internet (I forgot where I found it, but it might even have been here at Apple).
The script worked perfectly fine in Tiger and Leopard but throws an error in Snow Leopard. The error says "Can't make alias "...filepath... "into type file."
The problem is that I can't find the problem in my script. I don't get any indication which line it may be and I hope someone here will be able to help me.
I also tried Script Debugger, but the script works there! So that doesn't help either...
I'd appreciate any help, here is the script:

else
set the default_name to text 1 thru -((length of this_extension) + 2) of this_name
end if
return (the default_name & "." & the new_extension)
end add_extension

Here's the faulty line:
--open the image file
*set this_image to open this_file*
The command open doesn't return anything that could be assigned to the variable this_image.
I also wonder if it wouldn't be better to add “as alias” at the end of each of the following two lines:
*set this_info to the info for this_file*
*set the item_info to info for this_item*
I hope this help.

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

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.

HELP!!!! Just upgrade to Tiger and now nothing works

Please help me iv just upgraded to tiger and now none of my programs will open they crash on start-up, and also when i restart i get a little box with a blue globe inside it. then it goes to the unhappy face in a folder icon, then eventually it starts up. Please help me im buggerd without the mac.

Hi Andy!
What size is the Hard Drive, and how much space is avaialble?
How much RAM is installed, and is it original or added?
Did you use a Full Retail Version, of the Tiger Install DVD, to upgrade?
Did you do an Archive & Install, preserving User settings & preferences, installation, and if so, is the Previous System folder still on the HD?

Syncing 2 operating systems Tiger and Leopard on 1 Mac is this possible ?

On my newly dual boot G5 I see myself living in both Tiger and Leopard equally and wanting to open access and update my Itunes, mail, calendar, and iphoto in either boot instance and be able to trust that all are in sync. Can it be done ? BTW the apps are all duplicated since there are two application folders 1 per OS, I knew you knew that

iTunes should update content when pointed to the Music file.
The only problem with this is that the two xml files get updated for each OS version separately.
I don't keep favorites, ratings, etc., so it isn't a bother to me.
For those that it matters, something like this may help:

You might also ask for suggestions in the iTunes forum.
The people that "live" iTunes are over there.....
WOW that worked japamac ! Thanks I'm going to test by adding media in one OS then see if it appears in the other's Itunes library. If it does then this is exactly what I was after !

G4 MDD FW800 Dual Boot Tiger and Leopard

I have a Power Mac G4 1.25 Dual MDD FW800 currently running Tiger 10.4.9. I would like to install Leopard on a partition or a second hard drive so I can dual boot between Tiger and Leopard. Will the FW800 model allow this without eliminating Tiger or creating any issues with using Tiger? I recall reading somewhere that the MDD FW800 could not run Jaguar and Tiger concurrently but I don't know if this is true? Anyone running this Tiger-Leopard dual boot setup?
Thanks Della

Your MDD's are FW800 also?
What you are asking doesn't matter.
ALL G4 machines, including ALL MDD machines, including the FW800 CAN maintain two or more OS versions (such as Tiger and Leopard) and CAN boot back and forth between the versions.
Any G4 that I have ever had, Sawtooth to MDD/FW800 has run two, three and four OS versions.
I currently have OS9, Panther, Tiger and Leopard installed on this machine.
Another source had told me that the FW800 MDD could not boot back to a previous version OS once a newer version OS had been installed ie once Leopard was installed you could not boot from Tiger again from another startup disk?
Your source is incorrect, and is telling you contrary to all the content of the entire internet regarding the topic.
The FW800 cannot boot to OS 9 (any version) nor can it boot to OS X earlier than 10.2.3.
As with ANY G4, it cannot run OS X Snow Leopard (10.6).
Those are the ONLY limitations.
ALL other OS versions after OS X 10.2.3, in any number of combinations, may be present as boot volumes on the machine.
If you had 4 drives with 3 OS versions each, as long as the version was within the machines compatibility, it would be fine and boot would be supported.

Running Tiger and Leopard togther?

I have a question and I'm not sure where to post it.
I am currently running 10.5.5 Leopard, but will be using a piece of software that requires Tiger. Is it possible to "live" partition my hard drive into a third partition (Leopard is #1, Windows via bootcamp is #2)and then change the startup disk mode to select Tiger with the install disks in the DVD (I have a legit copy...from my apple purchase)
Do I loose info? Does it ruin firmware settings for video/graphics cards, etc.?
If, instead, I create an external boot drive of Tiger, will I potentially mess up my computer with firmware stuff, etc...and ruin my Leopard installation when my computer starts in Tiger or restarts in Leopard?
I am confused. Does the firmware and other stuff get loaded each time OSX starts?
Is there another way to achieve my goal? Tiger running concurrently with Leopard but WITH LEOPARD INSTALLED IN THE MACHINE FIRST. This, after Google searches, seems to be important. Most installs describe Tiger being installed on the internal drive FIRST and Leopard installed on an external bootable drive.
Thanks for an response.

OK, now I think I've got it...and I thank you for your patience.
I have leopard on osx disk
I have bootcamp partition already on the disk with Windows
I must start disk utility, select my osx disk and add a partition by clicking the add or "+" button.
Adjust the size I wish to make each partition size.
Apply.
Now, final questions:
Why the mention of bootcamp...
because Apple doesn't recommend doing what you are about to do if the bootcamp partition is present.
is it just to allow the "option" key startup when booting?
No. that option is always there and has nothing to do with bootcamp.
or live partitioning?
no. this has nothing to do with bootcamp either.
Can I resize my windows, bootcamp partition, before I make these adjustments and additions for Tiger?
no. if you want to resize it you have to either use 3rd party software like ipartition or delete the bootcamp partition completely using bootcamp assistant and create a bigger one after that. This will of course wipe your windows installation so you'd have to reinstall windows if you do this.
I also understand that creating this partition may be permanent until I reformat a hard drive.
yes.
One last comment. make sure you have plenty (and I mean PLENTY) of free space when you do the partitioning. else the partitioning process will fail.
Thanks again for you help. And yes, my imac originally came shipped with Tiger disks and OS installed.

Installing Tiger AND Leopard

Help! My macbook pro has been acting funky.
1. It won't let me install updates because it can't find the folder "/".
2. Every time I launch word, it thinks it's the first time.
3. Front row thinks I'm not connected to the internet when I clearly am.
The guy at the genius bar suggested re-installing the OS that came with the mac (Tiger) and then my current OS (Leopard). Everything is supposedly backed up with Time Machine. If I put the original OS Tiger CD in, will everything be wiped out? I'm a little nervous about the whole thing.
Can somebody please help? Thank you!
Jolivet

The first thing I'd try is a Leopard archive and install (after repairing the folder permissions and verifying the disk with Disk Utility). That will not erase your data.
Can you explain why the genius suggested you install Tiger first?
If you can't archive and install, then the next option would be to install Leopard with an erase and install. That will definitely erase your data (it erases you hard disk), so all you have left if your Time Machine backup. When you fist start up the Mac with the new Leopard you should plug in your Time Machine backup disk and when asked, specify that you want to restore from a Time Machine backup.

Tiger and Leopard compared bit-wise.

Hi guys, I'm not very familiar with the 64-bit-friendly part of the OSs, and if you don't mind me, I'll ask...
1. Wasn't 64-bit already introduced with Tiger?
2. What sort of improvement will this bring to Leopard in this sense?
3. Will non-pro users benefit from this?
4. Are the MBP going to benefit from this as well (as opposed to a Mac Pro)?
I was trying to read a bit more online before posting this, but there's no traces of Tiger in Apple's website.
Thanks in advance.

For most users, I don't think 64-bit versus 32-bit makes any difference. I don't know the difference between Leopard and Tiger, in this regard. 64-bit does make the memory ceiling MUCH higher (over 4GB I think), so pros who need a lot of RAM will benefit. All new Macs going forward will be 64-bit (ever since the Mac mini went to Core 2 Duo). The remaining 32-bit Macs that will work with Leopard (officially), are: G4 Macs above the speed limit, Core Solo Macs (only the 1.5 GHz Mac mini), Core Duo Macs. 64-bit Macs include the PowerPC G5 Macs. It will be interesting to see if the next NEXT major Mac OS X release "cutoff" will be for 64-bit Macs only.

I just upgraded from Tiger to Leopard and had to download Firefox 9.0.1 again. There's no way to organize bookmarks like there was before. How do I delete a bookmark or change a bookmark's position in the queue?

I have an iMac.

"Bookmarks > Organize Bookmarks" has been renamed to "Show All Bookmarks" in Firefox 4 and later.
