Utilizing Multiple-Processors in Classic Mode?

I have four PPC based scientific programs that will only run in classic mode. They take hours to run each, and so I am considering purchasing a Power Mac G5 Quad (2.5 GHz) to do so. Question: Can I run the 4 programs simultaneously, and can I ensure that each one runs on a different processor so that I will get the desired performance increase? (I currently run the programs on an iMac G5, OS X 10.4.11, and can run them all together if I want - but that doesn't improve performance...).
thanks,
Photonic

Apple made G4/500DP, 533DP, 800DP etc. And there are still cpu upgrades for pre-MDD models. The 1.42DP was the fastest made at the time, but not the only one, and not without some heat and noise issues.

One report showed Classic running on G5.
http://www.xlr8yourmac.com/G5/g5firstimpressions.html
And for some applications, they aren't written to, or benefit from running on multiple cores. And Classic is probably just such an application. OS 9 was not known for being efficient at giving foreground and background apps more cpu cycles.

Finding a way to run Classic efficiently on a current 2.8GHz 8-core Mac Pro?

You said that right now it takes hours to run currently on your iMac G5. Your Intel iMac running @ 3GHz might be able to run SheepShaver, but the more I looked into it, the more iffy it seemed. But that would answer the question of whether you need to look at a new $1500 Quad G5, or invest in something else. or use your new iMac.

SheepShaver - Although it took me a few days to get it up and running, in hindsight, SheepShaver was the easiest of the three to install and configure. This is due to the fact that, while it requires a ROM file like the others, this ROM file can be obtained from Apple installation CDs or update disk images available from their Web site. http://www.atpm.com/12.09/classic.shtml

What iMacs run System 9 software in Classic Mode and also iLife in Sys 10?

I understand that there were versions of System 10 that ran on iMac G3s that would run old System 9 software in Classic Mode, and also would run iLife (special interest in Garage Band and iMovie). What model of iMac would do this? What hardware requirements should I look for? What would be the optimal configuration to do what I'm trying to do?
Can I hook up an external floppy drive to an iMac? Are those drive still easily acquirable?
What versions of systems 10 ran in Classic mode? I've heard that System 10 with Classic mode can be buggy. How significant is this? When did System 10 stop running in Classic mode? Is it traditionsal to get System disks included when you buy an iMac off of eBay?
Thanx.

Ed,
The last version that would boot into classic is 10.4.X (.11 last version). That said I was never a fan of classic mode. It never seemed right to me that's why I set those few up as dual booters. They were used in a classroom with pre k thru middle school kids.
If you are using classic mode and it runs good for you than go for it.
My computer at school runs at 600 Mhz and has 256 Mb of memory. How much memory would you suggest.
Tiger will actually run at 256 but would be better at 512 or 768.
How would a machine like that do as part of a wireless network?
It should do fine. It will need a special adapter (which I can supply) and the original Airport Card.
Could it be connected to a network that's administered by a PC?
Should be no problem. Our's is set up that way and wireless Macs work fine. The problem I've seen w/ PC administered networks is the Administrator him/herself.
what is a G3 slot loader?
There were two types of G3 iMacs, the early tray loaders and the later slot loaders.
700 and 800 eMacs will also run OS 9.
So I just upgraded our music room at the school. It has iMac G3s 450 - 600s, eMac 1.25s, G4 Minis and Intel Minis. So we're running iLife 09 and 05.
Garage Band 09 will only run in 10.5.6 and that will only run on a G4 or better w/ a processor 867 MHz or faster. My son runs it on his eMac 1.25 GHz w/ 1.5 GB RAM.
Oh for your kid check out Kid's Pix 4 it runs in either OS. Our kids are also crazy about Zoombinis.

Installing Classic Mode on Tiger, DVDs, emulators

I want to install classic mode on a Mac running OS 10.4 (Power PC processor). We have DVDs for three different kinds of Mac of the same generation, but none of them come with the extra tools CD/DVD that is mentioned in Apple's instructions and in other posts as containing OS 9. The install DVDs are the Swiss (German) version. Is the third DVD only in the US version?
We have 9.0 CDs for two Power Mac G4s, plus one G4 computer that's broken, and one that's alive and well, running 9.2. Is there a way I could lift the system folder from this computer, copy it onto the hard disk on the 10.4 computer, and "bless" it, or is more required than the system fold for classic mode to run under Tiger? I'm wondering whether it's possible to install an emulator like Sheepshaver, since I could start with 9.0 and upgrade that to 9.2, and then transfer the necessary files (system folder plus ...?) to use the built-in classic environment.
Any help would be much appreciated.

You don't say exactly what computers are involved which places us at a disadvantage in helping you.
If you have a copy of OS 9.1 or greater on a computer you can simply copy the whole System Folder to a PPC running Tiger and set it up to be Classic. Put it at the root level next to OSX's "System". If you actually want to boot to OS9, that's where knowing the details of the computers and operating systems involved is essential.
Technically, system installations can be machine specific, but I think for OS9, and especially when used as Classic, this isn't as much an issue. Classic isn't in charge of any hardware anyway. Some people may post saying, "Oh, it absolutely must be installed correctly," but frankly I have copied OS9.2.2 from computer to computer as I worked my way through models and had it work on any model that supports OS9, and that was for booting.
If all you have are installer versions of OS9 on optical that is where you may run into trouble and may ultimately end up needing copies of the original discs (which likely are no longer available). You will have to get the computer to boot to the installer disc in order to get it to actually put a usuable copy of OS9 on the computer. Again, this is where knowing the exact disc versions and exact computer specifications is important.

Won't save in classic mode

I have a G3 iBook with OS 10.3.9 and OS 9 that runs in Classic mode. My applications that use classic won't save to disk. I get a message that says "File saving not allowed in that area". I bought the computer used so I don't know how it was set up. What do I need to do to get saving permission in classic mode?

Thanks for the tip.
I did run the utility and the log showed errors found and repaired. I ran it a second time and no errors found. I started up Excel, which runs on classic on my machine, and tried to save to the desktop. I got the same "Saving in this area not allowed" message. I bought an external disk by Lacie to use as a backup and I can't even save directly to that disk when running an application in Classic mode. I can save a file to disc in Texteditor, then open it in Word and save the file in Word, but I can't save a new file created in Word.

How do you install "Classic Mode"? The online guide doesn't match what I have?

HI -- I have a MacBook Pro and need to install Classic Mode so my kids can play some of their games ... I looked online, got instructions to go to the disks that came with my computer and that Classic Mode would be there. But it isn't. What am I missing???

There might be a terminology issue here.
Classic is the ability to run OS 9 programs on PPC-based OSX computers. It would not have been included with a MacBook Pro which runs an Intel processor.
Rosetta allows an Intel-based computer to run PPC based *OSX* programs. It will not allow you to run programs that required OS9. This *is* included with your MacBook Pro.
Are these OS9 (or below) games or PPC games for OSX?

T540p unable to right-click with virtual buttons in trackpoint or trackpoint classic mode 19.0.12.61

For a while now, I have wondered why the virtual buttons shown in the utility http://imgur.com/Lljj1Z7 don’t function as advertised. According to the utility, I should get a left click if I depress the left are of the touchpad, a middle click if I push on the bumps, and a right click if I depress the right half of the touchpad. In my experience, I get a left click regardless of where I depress the touchpad. The only exception is when I depress the bumps in the top middle of the touchpad—when I do that, the mouse enters some weird scrolly mode where I scan scroll stuff with the trackpoint. It definitely does not emit a middle click. But, more importantly, I cannot figure out how to get trackpoint mode to emit a right click. How do I get trackpoint classic mode to work? Is there a way to downgrade the drive or use a non-lenovo branded driver to get it to behave properly? Right now, I’m relying on an external mouse just to middle click and right click. I’m using Windows 10 b10240 and, as in the post’s title, my trackpoint driver is the latest listed on Lenovo’s support site (which I think WU actually installed for me)—19.0.12.61. Why don’t the virtual buttons work and are there any other workarounds that don’t involve using a mode other than Trackpoint Classic?

Looks like the middle mouse button can be made to behave with registry hacks discussed in https://forums.lenovo.com/t5/ThinkPad-X-Series-Tablet-and/How-do-I-change-Middle-Click-to-normal-Middle-Click-instead-of/m-p/1361971/highlight/true#M23357 . To quote:johnbruer wrote:

Which recent Macs run OS9 best in Classic Mode?

I'm not sure if I'm posting this in the proper forum. I wasn't sure where to post.
I have a old Power Mac tower with OS9 that's taking up a lot of space and I'd love to get rid of it. I've been using OSX on my laptop for years.
The problem is that I have zillions of documents in OS9 that I need occasionally so I'd like to transfer them to a newer and smaller computer that's capable of running Classic mode reasonably well. Any suggestions would be much appreciated.
Thanks!
macbook Mac OS X (10.4.8)

Hi monimac;
Since all of the recent Macs are based on the Intel processor which is incapable of supporting Classic, the short answer is none.
As I see it you have two choices here, either migrate the documents over to an application that runs under OS X or get a second hand systm that still supports Classic.
When I made the migration from OS 9 to OS X, I did not find converting my documents over to OS X applications to be that difficult of am undertaking.

Suddenly unable to print, or access Classic mode

Cannot print from any applications, and the error messages are absolutely no help.
"Unable to print"
"Cannot print document"
"Cannot print illustration"
and Classic mode won't open up.
Not sure how this happened, I didn't change any settings.

"The first is to repair 9 permissions in Panther's Disk utility"
This solutions worked a treat for me!
I'm so pleased you posted these easy-to-get-my-head-around solutions.
as i said, i first verrified the permissions, then i repaired the permissions.
I did both of these right from the disk utility. now starting up os classic works properly, and printing to both machies, over usb and ethernet works fine. i needed to re-add the ethernet prnter and do a small amount of finagleing to get the drivers to match, but that was not too difficult. the USB part was easy of course, because it's the only item attached using that cable; and there was no real networking to be concerned with.
honky, do try the suggestions posted, because they really were quite painless. and after days of panicking, they are a welcome resolution.
thanks again carl!

I NEED CLASSIC MODE AND I CANT UPGRADE!! HELP!!

So i just bought a new mac mini about a week ago and I am very excited to start using my copy of adobe photoshop cs2 again, but i have a copy of adobe photoshop 6.0 and i use and upgrade to go to photoshop cs2. I just found out that i cant install photoshop 6 because mac no longer supports classic mode! so how do i get classic mode with out having to downgrade to mac OS 9? is there another way around this?? I don't want to have to buy a 600 dollar copy of photoshop just to use the copy's i already have!

You may want to learn about upgrade pricing. It is unlikely that you paid $600 to upgrade Photoshop 6 to CS2.
Beware that CS2 was written for PPC processors. You have an Intel processor and Apple hints that a coming Lion may not support PPC apps. You might want to upgrade to CS5 while you have the opportunity before you fall out of the upgrade window (when CS6 arrives). CS5 is written for Intel.

Can't run software in Classic mode

Boy, I've tried to fix this myself and just can't. I have a new out-of-the-box Mac Mini with a generic USB keyboard. I've got some old Mac software (really old) which is really a main reason I bought the mini. I can't get Classic to run because it's not already installed. I have the OS9.2.1 disc, but I can't boot from the CD (I tried pressing C on bootup -- either my Mac can't boot from CD or my keyboard doesn't communicate properly). When I try to run the OS9 installer to get Classic to work, I get the hair-pulling error message that I need to run the installer in Classic
mode.
A friend said I need the discs which came with the Mini, but I don't think there are any. Can the software which should have come with it be downloaded and burned on to a new CD in order to create a bootable CD?
Argh!!! Please help!
Warren

Thanks -- I did try that, just forgot to mention it. the CD isn't one of the options in startup disk. It says I can choose the hard drive or the network, and I've tried both. A friend said that Mac Minis can't boot from CD -- don't know if that's correct or not, but I can't seem to get it as an option.
I've tried to find any CD that may have come with the Mac Mini -- my friend said to look for one called "additional software and apple hardware test CD that came with the Mac Mini" but that is nowhere to be found. Either it didn't actually come with it (my hunch) or the staff in the receiving department took them out for safekeeping and hid them in a drawer somewhere and have forgotten. (Also possible.)
I can't imagine that I'm the only person in the world with this problem, but my tech support staff warned me in the first place. I wanted to try using some macs mixed in with our PC setup (because they can run this software, and because it seemed easy) and they said that they wouldn't be able to provide much support, since they're all PC people. I figured "how much support can it need? They're designed to be easy to use!" Oh well.
I'd really be keen to get any more suggestions from anyone who can help!!

Running under classic mode - Standard Options

In WLS 5.1 server, there was an option to run under classic mode in a UNIX environment.
We just upgraded to WLS 6.1 and in the docs, http://e-docs.bea.com/wls/docs61/perform/JVMTuning.html
it mentions classic mode available in NT but not in UNIX.
Does anyone know if the java option -classic will work under 6.1 and if not, what
the new option is.

-classic asks the JVM to use the old non-HotSpot JVM. First off, why do
you want to use it? It's most likely slower.

Can I use the old Classic mode on a new iMac?

On my old iMac G5 running OS X 10.3.9, I also had a "Classic" mode that worked with all my old apps. I just bought a newer iMac (10 months old) running OS X version 10.6.6. Can I install Classic on it too? If not, is there some other way that I can run my old Photoshop, Word etc. on my new computer?

The various free Office-like open source applications are great, however learning to use the Gimp, for anyone who is used to the way Photoshop and Mac programs work, is a challenge. And that is an understatement of the case! Instead of struggling with the Gimp, for less than 100 bucks one can buy Photoshop Elements. It will do everything the Classic version of Photoshop would do, that "regular" people would want, and then some (there are some things that professionals do, such as working with CMYK, that Elements doesn't do). Another option is Pixelmator, but I've been trying it (it was on sale in the new Mac App Store), and it just isn't as good as PS Elements, and its regular price isn't all that much cheaper.

Using multiple processors and threads

Hi there,
Just a quick question... I am working on an application that is VERY processor intensive. There is no real way to improve this, but I do have access to a multiple processor server.
Can anyone tell me if Java code can be written to utilise more than one processor? I assume due to the VM, that this is unlikely - and that one must resort to the operating system used on the server, where hopefully the VM can be forced to use more than one processor.
If this is not possible - has anyone written applications that run across several VMs? Is this possible, and what is the performance like?
Thanks for any help.
Nick

The Java VM will indeed utilize multiple processors. Just create a seperate thread to do your work and it will schedule it. In fact it's way easier than most languages:
public class MyThreadimplements Runnable {
public MyThread() {
try {
Thread newThread= new Thread(this);
newThread.setPriority(Thread.MIN_PRIORITY); // see other enumerations to boost priority
newThread.start();
} catch(Exception e) {
System.err.println(e);
public void run() {
// do your work here
}

How can you FORCE Classic mode to run on an Intel Mac? OS 9 emulation Rosetta Software Design

Hello everyone, I had a few thoughts on running Classic mode on intel macs which I wanted to share.
Now I know little about software design, but maybe someone who does could tell me if these ideas I had are at all feasible:
Now in the first place I now that, technically, "Classic" mode went out back with Tiger because of the switch to Intel chips. Switching to Intel, Rosetta was required to "translate" pre and non-intel OSX applications, with the exception of Classic since Rosetta does not translate deep enough into the system to do that. As a substitute to Classic, SheepShaver, Basilisk II, etc. can be used to emulate OS 9, but these are very lousy applications compared to Classic mode.
Is there ANY way whatsoever Rosetta could be edited, or Classic itself so that it will work on intel macs?
(that is, with the exception of 10.7+ systems since these don't even use Rosetta)
I know if Classic was placed on an intel mac, it would tell you to download Rosetta, but from there will crashes because frameworks in the system's library does not support (or was not designed for) Classic...
So what I wanted to know:
What if an old, Classic supporting PowerPC system's library folder was added to an Intel computer in a location other then that computers real system folder (as not to confuse the real, current system) and Classic manually edited so that it would search for the needed frameworks/etc files in the new location? Would it work?
Since, after all, it now has the correct "system" to run on (which before Rosetta could not convert), do you think there's any chance it would work and function properly?
Now beyond that, I wouldn't know the actual results (or consequences). I suppose the main problem to consider would be that the the PPC's system frameworks/etc wouldn't work at all on an Intel (which leads us back to Rosetta lacking in this area), and since those frameworks will be searching for other files in the system library (which would bring them to the current, Intel system) the same results would happen: crash! Or maybe sensing the system was mixed up, one or more files would try to "fix" themselves, and in turn destroy the computer's real system.
So, would it be worth a try?
I'd love to hear any other thoughts on running Classic on Intel...

There is an "easier" way to acquire SheepShaver called Chubby Bunny and I have put together a post with some safe links that are relevant to this topic. I see that emaculation is one of them.
Why do you need OS 9 greater than 9.04?
Feel free to let me know if you need any more help.
With the newer Intel Macs, you have to run a Classic emulator such as SheepShaver, which requires you to extract the Mac ROMs from your older Classic Mac and then install Mac OS 9.
A related program is Chubby Bunny, which comes bundled with all of that included.

Can I use my Mac OS 9 emulator (classic mode) with OS 10.5 Leopard?

Hello,
This was the closest forum I could find to ask this question so please forgive me if it's not categorized properly.
I'm currently running OS 10.4 Tiger on my Mac and my OS 9 emulator works great. I've heard rumors that if I upgrade to OS 10.5 Leopard I can no longer use the OS 9 emulator and/or it will be eliminated all together. Can anyone clarify this for me?
I still use quite a few OS 9 applications, much less some older games which I really enjoy and do not want to lose the use of 'classic mode'. I would actually reconsider upgrading if I were to lose the use of it.
I've heard there's a workaround by using SheepShaver, but I've read a lot of mixed reviews on it so I'm hesitant to go that route should I decide to upgrade since everything is working so well with my current configuration. I'd like to take advantage of the new features in Leopard, but I don't think it's worth the sacrifice if I lose 'classic mode' by upgrading.
Any information/clarification would be much appreciated. Thank you.

Hi, lancisti -
Welcome to Apple's Discussions.
First, a point of clarification - OS 9 used as Classic is not an emulator program. SheepShaver is an emulator, but Classic is not. When OS 9 is used as an Operating System, it is referred to as OS 9; when used as a program under OSX to provide an environment in which many OS 9 programs can be run, it is referred to as Classic.
Unfortunately, Leopard (OSX 10.5) does not support OS 9 in any form, including Classic. There is no workaround supported by Apple for this.
As far as non-Apple workarounds go, SheepShaver is one approach, as you are aware. And, as you note, whether it works well, at all, or not seems a bit whimsical based on some users' reports. This may have something to do with SheepShaver not yet being ready for Leopard - that's purely a guess on my part.
Another solution would be to partition your hard drive, or add a second one, so that you can have a volume dedicated to OSX 10.4.x, which does support Classic and would allow you to continue using it. Or, since your machine is OS 9 bootable (using the model-specific version of OS 9.2.2 that came with it, and is installable from the machine's original disk set), set that additional volume up as an OS 9 boot volume.
