WOOFER  I'm just wondering/hoping, if this niffty little programme might be updated soon to let users with under 900MHz G4 Macs to install OS X 10.5?

It seems Apple have limited 10.5 for either Intel users or better than 900MHz G4's

Fingers x-ed.....

MACTINKER  Hi! XPF was recommended to me by a list mod to help in installing 10.3 on a beige G3 AIO. I have asked Apple and they tell me that 10.2 will install and run on this Mac just fine. I went to the list in question looking for 10.2. But the list mod was very encouraging about the superiority of 10.3 over 10.2, so I tried to dl XPF4.

I got a page of very strange code, and no actual dl at all. Thought you'd want to know about that.

Three questions:

1. Does anyone know what I might have done wrong in the dl process? I clicked the "Download now" button, that's all, and all that appeared to be necessary. Or maybe it can't dl to OS9?

2. If I can get hold of a set of 10.2 CDs, do I still need XPF? (Apple says no, just fyi, but if *users* have different actual experience, that's helpful to know.)

3. (Slightly OT) If I could just go altogether with X I wouldn't ask this, but: Does anyone have an opinion whether 10.3 is really so much better than 10.2 that I need to add to the complication of making the switch? It's going to be tight in the first place, as I need to partition the HD so I can have one side w/ OSX and the other w/ OS9, because I actually do use the built-in floppy and zip drives, both unsupported under all versions of X. Can't go get a USB floppy drive, because the AIO does not have USB ports, which are required by 10.3.

Thanks for your time.

MACGURUGUY  I think this is the version that has worked the best. Finally stable on PowerTower Pro w/Sonnet 800mhz G4 card. Keeps this machine and investment going for the long term. Ryan (the author) has definitely put in some long hours developing this software, and I can tell you that he has come quite a long way. This software actually works quite smoothly compared to a year or so ago (when I couldn't get it to work at all). Ryan is also frequently vocal in the forum associated with this software (which hadn't been the case previously). If you've got an Old World machine with a fairly speedy processor (I really wouldn't recommend using OS X on anything slower than 500 mhz), then this may be the time to make the leap to OS X.

I highly recommend...

ROB J. SHREAD  Hi. I've been playing around with XpostFacto for a few months now on and off. I've got an 8600 and a 9600, both retierd. I've got a G3/300 board for them and 512 ram as well as an UWscsi/ATA66/usb all on the PCI bus.

Originally I wanted to put OSX on the 9600 becuase then I could run an additional graphics board and a FireWire card.

Panther wouldn't run on the 9600, I couldn't work out why for a while.. It'd bring up the Gray Apple but then just stall during boot. I worked out it was becuase both of my graphics boards were too old for Panther. I used the settings with in XpostFacto to try and fix this, the closest I got was half of the installation screen.. Until I come accross a beter PCI graphics board the 9600 is a no go for 10.3.

Although I knew the graphics would be slow, I turned my attention to my 8600. After playing with configurations for a while, I worked out that I could run OSX of the UWscsi bus (PCI) as long as I set up a helper drive on the Mac's internal bus. Basically to act as a diversion during boot. I also had to slow down the boot procedure (throttle) to allow for this to happen before the Mac got upset.

This worked, and so my 8600/G300 with 512mb is running Panther resonablly well. (I was suprised at how quick it was actually).. I had actually bought an additioanl 2mb of VRAM for the logic board.. but under OS9 it insists on using it for a second display on the composite video out regradless of what I tell it. OSX see's the full 4MB on the board and lets me run 1024/768 at 24bit.

So, there you go.. One did One didin't, Nither straight forward. (I went to reagrange the drives in the 8600 last week.. won' even boot OS9 now) You win some ya loose some.. Cheers.

BTW: A logitech USB mouse and a Medion Graphics-tablet perform nicely.

In fairness, Sonnet's tech people were very responsive; I have no problems with their customer service. They had told me way back when to contact them by phone about the Jaguar problem, but I got sidetracked and moved on to other things.

Today, though, I needed to install Jaguar on the old system, so I decided to give XPostFacto a try. It worked like a charm. I'm most impressed.

PURRING ALONG IN 10.3.5  The OS X 10.3.5 update hasn't broken anything I've found on my two XPF-upgraded machines. Although I was updating from 10.3.4, I downloaded and ran the 10.3.5 combo updater. I ran the security update right before that (apparently not needed, as it was included in the 10.3.5 update). I ran the JAVA 142Update1 package afterwards.

Everything's been working great for me for some time. About the only thing I could have asked for in the past would have been some sort of hardware compatibility scanning utility to use beforehand. It was a bit of a feat installing on a 9600 with old video cards. I was able to do it nearly-blind using one old card giving me mostly-unreadable dithered monochrome during the OS X install, switching to my other (different) ancient card afterwards for normal use. Neither card would work for both. The support forums were very helpful, but it would have saved considerable time to have a utility spot the more obvious (to the informed) potential problems.

Performance 10.2.8 vs 10.3.3:

CPU: + 30%

HDD: + 30%

RAM: + 250%

Grafik: slow (25% of 10.2.8)

But the display of videos likes better and faster than under 10.2.8.

Thank you very much for this utility. It's a very great work.  
(Version 3.0a17)

DAVE PURDY  Well done, Ryan. Really nice. Just a few tweaks and improvements needed.

Although technically still at alpha status, I have used XPostFacto 3.0a17 to install Panther (10.3 and 10.3.2, both upgraded later to 10.3.3) on two Beige G3's (530MHz and 420MHz). They are very usable now with Panther, running just the onboard ATI Rage Pro video. My main work computer (Beige 530MHz) is running Panther. It is snappy enough (not as quick as my MDD 1.25GHz of course) and seems a bit more responsive than Jaguar. Very satisfying results.

I did have a few hiccups along the way. They were best avoided when I:

1). Freshly partitioned the target HD with separate OS 9 and OS X partitions (OS X partition within the 1st 8GB),

2). Installed 9.2 on the OS 9 partition first, booted into 9.2 and started XPostFacto's Panther-install process from there,

3) Directly after the first CD in the installation process finished and the computer booted Panther for the 1st time, I switched System Preferences>Energy Saver>Hard driver never sleep & Screen sleep after 1 hr. This seemed to eliminate/lessen the frequency of the video panics (mentioned at http://www.opendarwin.org/bugzilla/show_bug.cgi?id=1708 ). After that installation, booting (from both HD and CDROM) has been normal.

The video panic was (black screen, unrecoverable from it) initially a problem - repeatedly half way through the second install CD the screen would go black and the installation would halt. The solution of setting the screen to sleep after an hr or 30 minutes was a counterintuitive one (for me at least), but it has continued to work for me. The video panics still sometimes appear, but only very infrequently (once a week or two). I am confident that Mr Rempel will find the source and a fix for this problem, just as he has solved some other issues.

Another area that should improve as this software progress passes the beta stage is that of installation ease. I had success only when doing an install on a truly fresh partition - a complete partition of the entire HD into 2 or 3 smaller partitions. Perhaps in later versions one will be able to install without having to repartition the entire HD.

My final item is a request... I hope that when the post beta XPostFacto is offered we can seemlessly and _reliably_ uprgrade our alpha or beta versions without having to reinstall Panther.

This product is a good one. Version 2 was indispensible for those who wanted to run their pre-Beige machines in Jaguar. Now version 3 is a must for those of us who want to move to Panther with our beige boxes.

I look forward to the finished product. It is well worth the $10 shareware fee.

ANONYMOUS  This will be the GREATEST thing since sliced bread for the "Beige" community! The only thing stopping me from sending money is the sleep issue :-( For me, on an older machine I would prefer to "sleep" the machine when I'm away from it (i.e. to save the life of aged components).  
(Version 3.0a16)

ANONYMOUS  Used 3.0a14 to install Panther on a Beige G3.

Built-in video was tried, but didn't work.

The mac has a 16MB ATI Rage 128 PCI card installed and it worked.

The mac is also upgraded with a 500Mhz G4 ZIF and the bus speed running at 83Mhz.

Installation was not effortless, but after a few tries it did work.  
(Version 3.0a16)

ANONYMOUS  Works great with a Sonnet WSG4 upgrade and Panther on my Wallstreet, but until sleep gets figured out I can't stick with it. When sleep gets wrapped up, there won't be a single reason to not go with it for me (even the S video out works perfectly!).

ANONYMOUS  Does anyone know if the built in Video In of a 8600 is supported?

MICHAEL RIECHERT  XPost is one of the best utilities in the mac scene and overall it is free. For two years I tried to install on my beige PowerPC G3 with 466 Mhz ( old Formac ziff card) and 640 MB RAM and ATI Radeon 7000 at first Jaguar and then Panther without any success. The way ended with MacOs 10.1.5. Yesterday I tried xpostfacto 3.0a15 and after twenty minutes I had installed Panther on my beige G3 without any problems. I updated to 10.3.3 afterwards. The system is fast and stabile with xBench value of about 36. I am now very happy, because I can use my old beige G3 with the latest system with very good speed. Many thanks to Ryan Rempel for his outstanding marvellous work. Greetings from Munich, Germany Michael

RHODEE  This piece of software is absolutely terrific. I don't doubt that Apple wished that they had done something similar for their customer base.

On a PM9600 G4 XLR8 450mhz, 1.216gb RAM and a Radeon 7000 ME video card, and using XPF3.0.a14 my Mac is as fast and fun to use as our ibook G3 500 mhz. Actually more fun since I have the larger 17 inch Sony monitor.

Now I must say that this has not been without some pain. But for most of us on these Legacy machines well worth the experience.

Cheers, Rhodee

EMMA PEEL  does it work with a Twentieth Anniversary Mac?  
(Version 3.0a15)

TONY  It does not work at all for my Powerbook G3/266 with 10.2 already installed and trying to go to Panther. I have tried various versions of XPF and all have failed!!

I have had to reinstall the 10.2....many hours of wasted time!!!  
(Version 3.0a14)

ANONYMOUS  Works flawlessly with OS 10.3.3 on a beige.  
(Version 3.0a14)

ANONYMOUS  Works perpekt with my G3 beige.

Bur i used an Panther 10.3.2 image (CCC) from my fresh iMAC G3 233 install.

Most problems maybe occur at booting from Panther CD (with XPF). My G3 beige won´t boot at this way to install Panther.

So i came to the idea to use an fresh Image from my IMAC after putting XPF Support (install extensions and bootx).

The 1,9 GB image take some time over LAN 10MBit but the G3 beige start up perfekt , after backcloning the image with CCC to beige and setting this partition as startup (using XPF).

MIKE S.  Testbed: G3/400 (Upgraded Power Macintosh 8600/300) running Mac OS X 10.2.8 with 464 MB RAM

Summary: Let's be honest; a new computer is expensive. Five hundred dollars will buy you a pretty good PC but five hundred dollars is not pocket change. Buying a new Mac is an even bigger investment and nobody likes to get rid of a perfectly functional computer.

Enter Ryan Rempel, creator of XPostFacto, an amazing combination of OS X kernel extensions (KEXTs) and a GUI front end that allows you to modify your Mac's Open Firmware and send Mac OS X start up commands.

XPostFacto achieves what Apple refuses to do; allow a wide range of PowerPC 604 (or better) Macs to install and run Mac OS X, breathing new life and functionality into the quality hardware Apple customers have invested premium dollar in.

Here is how it works, you download XPostFacto, double click the application, select an OS X boot disk (be it CD or HD) and click Restart. XPostFacto takes over from there and it works incredibly well.

If you dig deeper into the application you'll find options to designate an input and output devices via Open Firmware. This worked great for me as I have a PCI Radeon video card and as of XPF version 3 alpha 11 I now get the white Apple boot screen where as before I would see nothing but black until the "Welcome to Macintosh" Aqua progress bar would appear. It's a little touch, with some useful benefits, that makes the system feel more complete and less like a hack.

Advanced Users may opt to boot OS X into verbose mode or see any kernel panic info; even access the debug data that only a developer could love.

The execution is done with such beauty and ease that it completely belies the technical difficulty of what has been accomplished with this utility. Ryan Rempel is, in my opinion, an unsung hero of the Macintosh community.

This is a person who has allowed thousands of Mac users to be a part of this new Macintosh renaissance. People who Apple has willfully left behind in a bid for higher profit margins as they continue to intentionally obsolete perfectly functional computers by removing existing support from new Mac OS X releases.

XPostFacto is not perfect, some features simply do not work under Mac OS X while they do under Mac OS 9 but one can hardly hold this against the utility or it's author.

Simply put, XPostFacto increases the value and longevity of your "legacy Mac" and allows you to experience all of the incredible work that Apple's software engineers have done without requiring you to needlessly spend hundreds or even thousands of dollars on new hardware that you may not require right now.

Don't get me wrong, Apple's new hardware is amazing but I simply do not need a new machine for anything when my upgraded 8600 handles all tasks well; This is a testament to Apple's engineering prowess but their actions with regard to Mac OS X proves they are a large corporation like any other.

Pros:

• Mac OS X on your Pre-G3 Mac!

• Simple to use interface with powerful options.

• Now able to be used from Mac OS 9 or Mac OS X

Cons:

• It's almost unfair to mention any because this utility is constantly doing the impossible without a guidebook but in the spirt of balance...

• Some features won't work on some models (e.g.. sleep, system wide volume control, use of built-in video inputs) so be sure you read all release notes.

• May require some hardware changes and/or upgrades. (e.g.. I had to switch my internal SCSI drive to the slower SCSI 1 BUS to allow it to boot as it would halt when attempting to communicate with the disk on the Fast SCSI 0 BUS)

• Current version has issues with G3 L2 "backside" cache and defaults to disabling it (enabling it caused a kernel panic at boot on my machine but another utility, CPU Director, may have enabled it again. This is unknown as System Profiler may be giving me bad info)

Bottom Line: I have nothing but respect for Ryan Rempel and praise for XPostFacto. If you've got a PowerPC based Mac (no 601s or 603s, sorry.) that Apple has abandoned then give XPostFacto a try so you to can leave Mac OS 9 where it belongs... in the past.

C B PONTON  Ryan, you have done a BRILLIANT job with 3.0a11 so far, bar the L2/L3 cache config and on-board video glitches!!

I have used it to successfully install Panther on my Beige G3 Desktop (Rev.1), which I use as my main office computer since buying it new in 1995, alongside a less-used 1GHz Windows PC!.

It is fitted with a Sonnet G4 500/250 MHz 1 MB L2 backside cache (2:1 ratio), 768 MB RAM, Acard 6280M ATA/IDE PCI card, USB 1.1 PCI card, Maxtor DiamondMax Plus D740X6L060J3 60 GB HDD, external SCSI ZIP 250.

I did not remove/change any of the above before running XPostFacto, which successfully installed Panther in the 1st 7GB partition (required) on the Maxtor HDD.

It did so with L2/L3 config "on" as far as installing system from Install CD 1 but would not re-boot properly (ending up with "blue blank screen freeze") in readiness for Install CD 2. With L2/L3 config "off", the install and re-boot sequence worked without a hitch!

I used "0 throttle" and "force old video drivers" with verbose mode.

I also tried using Sonnet X Tune-up 1.2.7 to enable the L2 backside cache after installing OX 10.3 successfully. IT DID NOT WORK and in the process corrupted the formerly successful Panther install, preventing cold-booting even via XPostFacto!

So after another full (except for X11) Archive and Reinstall, I used the Powerlogix Cache Control X 2.1b4 application to enable the L2 backside cache. I then Software Updated to OS X 10.3.2 and ran SpeedStart to cure the 10.3.2 slow start problem.

All in all, it has only taken 15 hours to go from running OS X 10.2.8 full install to running OS X 10.3.2 full install with all current on-line Software Updates loaded, with everything (i.e. hardware and software) running as it did under OX 10.2.8! - NOT BAD.

Many thanks, Ryan. Keep up the good work!!!

ART KURTZMAN  XPF worked exactly as expected in loading OS 10.2 (later upgraded to 10.2.8)in two lagacy 8600 machines with with G4 processor cards. The computers are using ATA drives.

Thus far, the installation has proven to be perfectly stable and runs flawlessly.  
(Version 3.0a9)

MAC  Putting it simply. Xpostfacto is a remarkable advance in compassion for those who have a load of older computers and just can't quite justify their disposal. We are running a group of old macs as our servers and love what xpostfacto has done for us.  
(Version 3.0a9)

CHUCK  I've been looking forward to getting to put Panther on my Wallstreet Powerbook, but XPostFacto won't open. I don't have any 9 system on my machine and am running 10.2.8. Don't know what's the matter.

MACGURUGUY  A 'non' mac guru is just that. I gave my opinion of this product based on my experience. He made his comments as a political stab at my freedom of speech. The fact is that this whole product is a "wannabee" effort, because all of the machines it supports are no longer supported by Apple. YET, I applauded its authors efforts (this keeps getting ignored). If you want an honest opinion, all you have to do is read the comments, and make a decision for YOURSELF. I am a Systems Administrator, with two completely installed and networked mac systems in the last 6 years, which have been HIGHLY complimented. I deal with installation of software on a regular basis. My decisions to use a piece of software, both at work and home, is based on ease of use and installation. However, I would be willing to bet that a 'non' mac guru falls into the label of "computer geek". These people expect the rest of the normal world to understand and accept their intellect for wasting an entire day installing a piece of software, just to say it worked. Most of us have lives that demand us to use our time wisely. Therefore, the real question for using this software is: Are you a geek, or are you just looking to use your computer for work and pleasure?

And by the way, the nickname 'macguruguy' came from my former boss -- who introduced me to people as such.

PAWN  how bout this. i don't waste money i dont have . this utility, has worked on t he first time for me, each time i've installed OS X (any version). havent tried Panther yet. soon tho. my mac isnt a clone so maybe thats why it works properly with apple software. *7600 with 400 mhz G3, 384 mb RAM* soon to be a 700 mhz G4 with another sonnet upgrade. and im positive panther will install properly for me, with this software, cuz by the time i get panther... most the bugs should be worked outa this *ALPHA* release. Which most people are incoherant about.  
(Version 3.0a9)

MACGURUGUY  Don't waste your time with this program. While it is a brilliant effort, you will be far less stressed to purchase an actual G4 machine and upgrade it to your liking. I tried this program with two PowerComputing clones (for about six months), neither of which would run PROPERLY with Jaguar. I then purchased a G4 off of ebay, upgraded it with a 1.4 Ghz G4 chip, and installed Panther, which ran perfectly the first time.

GARY HOLDREN  I'm using an 8500 upgraded with a Sonnet Crescendo G4/450 card. This is a great app, but I'm confused. I upgraded to 10.2.8 using Sonnet's upgrade software and things run smoothly. As a test I upgraded to 10.2.8 on another drive using XPostFacto. The install went smoothly, but it runs like a dog. Very slow. It benchmarks at about half the speed as the upgrade from Sonnet. What am I missing. It's almost as if XPostFacto doesn't regognize the Sonnet card.  
(Version 3.0a8)

MARLEY  Just installed Panther on my Umax S900 with Xpostfacto 3a8. ATI Rad. 7000, Sonnet G4 450, 256mb of RAM, Sonnet PCI ATA card.

Was kinda a pain at first because it didn't want to finish the install with a IDE cdrom drive. I had to install with a old SCSI rom drive. Anyhow, thanks a bunch. This machine would be useless without this app. Works great and it's only Alpa. Oh and yes the bootscreen works for X. That didin't work with the older version of Xpostfacto.

ANONYMOUS  Take note, to whom it may concern: "XPF does not support 10.3 on Kanga or the Wallstreet Powerbooks yet, nor on the Beige G3"

ANDREAS MICHALAK  I tried XPF to get an Boot Screen from my ATI 7000 PCI. The G3 beige normaly adidnt´t show the gray boot logo or any textoutput (for fsck command etc.).

The option for selecting output device to the PCI ATYR100 card didn´t help to get an boot screen.

Any other G3 beige users with ATI 7000 PCI here ?
