It started out on PowerPC processors but later transitioned onto Intel processors with Mac OS X Leopard (10.5) the last to natively support the PowerPC architecture and Snow Leopard (10.6) the last to support PowerPC applications on Intel-based Macs. Apr 23, 2014 This is a video tutorial that explains how it is possible to install Mac OS X 10.5 on supported PowerPC Macintoshes using a USB thumb drive. This should work on. It started out on PowerPC processors but later transitioned onto Intel processors with Mac OS X Leopard (10.5) the last to natively support the PowerPC architecture and Snow Leopard (10.6) the last to support PowerPC applications on Intel-based Macs.

Contrary to rumors that Apple would drop PowerPC architecture support with its newest OS, a tipster and possible Apple insider was able. Apr 24, 2020 As all of you know, according to Apple, Snow Leopard runs only on Intel chips. Also, as a lot of you know, PPC and Intel versions of OS X report themselves as such, ie PPC 10.5.
In late 2008, I wrote an article about the future of PowerPC Macs, The Future of PowerPC Macs and Software as Snow Leopard Approaches. Well, all the rumours have been put to bed: Apple have announced the next version of Mac OS X, and it isn’t looking good for PowerPC users.
Scheduled for release in September, Apple are offering OS X 10.6 Snow Leopard at a knock down price of only $29 for existing OS X 10.5 Leopard users. At this point, I was excited. I was sure all the rumours of Snow Leopard being Intel-only were rubbish.
Intel Only for Snow Leopard
However, read the small print. It is only for Intel users after all.
Since the release of Intel Macs, it has been a waiting game to see how long before PowerPC Macs were classed as extinct. Even before the mention of Snow Leopard, more and more software was being released as Intel-only.
When a new OS comes out, you expect new versions of software to be for that OS only – that is the forced progression of computing – but when the same OS runs on two architectures, it makes it a little more difficult.
The last G5 Power Mac clocked in at 2.5 GHz with 4 cores – still a very respectable machine, and certainly full of life – but it won’t be able to run Snow Leopard, Adobe Creative Suite 5, or other Intel-only software, yet a 1.5 GHz Core Solo Mac mini will.
With recent announcements, it just seems another nail in the PowerPC coffin. Okay, it was inevitable, but how long before owning a PowerPC – even a fast one – will mean not running the latest OS or latest version of software?
15 Years of PowerPC Mac OS Support
The PowerPC platform was introduced in 1992, although the first PowerPC Mac didn’t ship until March 1994. The last PowerPC Mac in production was the above-mentioned Power Mac G5, sold until August 2006. This makes some of the last PowerPC Macs just over three years old, making them “old hat” in a very short time.
September will see the launch of Snow Leopard. Every new Mac sold will come with Snow Leopard, and any existing Intel user with a spare few quid will be upgrading. By Christmas, the Mac world will be awash with Snow Leopard and probably will have have seen the first update (version 10.6.1).
PowerPC users will slowly become a smaller and smaller minority. More and more software will be come Intel-only, as well as Snow Leopard only, leaving Intel Leopard users out in the cold too – but at least they have a cheap upgrade option.
By October 2010, Snow Leopard will be well into it stride, rumours of Mac OS X 10.7 will be flooding the Mac community, Apple will have a new bunch of peripherals and fancy gadgets that only work on Snow Leopard – and the PowerPC platform, along with Leopard, will just about be forgotten.
It’s Inevitable
Unfortunately, there is nothing we can do about it. It’s part of computer evolution. While the hardware in your machine may still be good enough to do what you need, the latest software and latest trends require a newer OS. A newer OS won’t run on your PowerPC hardware (even though most of the time it would be physically possible); therefore you have to buy a new (or newer) computer to keep up with the latest standards.
And this evolution just keeps going.
I’m a PowerPC user. My 867 MHz Titanium PowerBook G4 meets the minimum requirements for Mac OS X 10.5 Leopard, but as soon as Snow Leopard is released, my PowerBook will start the downward slope of being out-of-date.
Of course it will still do everything I need it to do at present, but it is a downward slope.

Mac Os X Snow Leopard For Ppc 1
What is (Beta 10A190) Mac OS 10.6 Snow Leopard PowerPC? Back in the late transition days from PPC to Intel Apple had to eventually cut the rope for PPC. When early reports of developer beta builds of Snow Leopard surfaced, Apple neither clarified nor commented on the further PPC support of OS X beyond Leopard. But when the golden master was handed out it was clear — and communicated by then — that support for PPC was finally dropped. Things rested for years at that point (at least to my knowledge; Apple engineers knew better for sure). Then, mid-March 2020 I was hinted to a tweet by tesco@system2048 who posted a screenshot of a working SL-PPC This information sourced from this MacRumors thread: https://forums.macrumors.com/threads/snow-leopard-on-unsupported-ppc-machines.2232031/ What ingredients are needed to start experimenting? The easy way:Below, the file PPC_SL_10A190.dmg is a bootable disk image of a system just after successful installation. Simply restore this image to a disk or partition using Disk Utility, and you can boot into the first time setup of a working Snow Leopard PPC install. Note that you will need to select 'erase destination' when doing the restore from the DMG file to ensure that the image is properly bootable. For more information, watch the 6 minute video walkthrough of the process above. The advanced way:Obviously, a PowerPC machine is pre-requisite. A copy of a developer build of 10.6 (server or client) will be needed, in addition to a handful of original kernel extensions from 10.5.8, a USB drive (or even better, a firewire hard disk), and a helper system in form of a Mac capable of running 10.6 out-of-the box (e.g., MacBook 1,1 to 4,1, etc.). In addition, if the installer of a server build is used, then at some point a license key will be needed to finalize the installation. The client versions, of course, never needed such keys. Suitable Mac OS X Snow Leopard build(s) The search currently goes on for intermediate PPC/Intel builds of Snow Leopard, but at present, the version proven to work are the builds 10A96 (server dev preview) and 10A190. There was probably a working build of 10A96 for clients, but this for now remains elusive (these would be labelled something like 'User DVD' or 'User Installer'). Between the 10A96 build and the “Golden Master”/GM (10A432) are several releases which we are looking for. If and when these become available for testing, we can check them for their PPC compatibility! Generally, G4 and G5 machines capable of booting from external USB or Firewire drives should be able to install 10.6 Machines to be verified (that might or might not be able to boot/run 10.6 with additional tools or methods) are all G3 PowerMacs upgraded with G4 processors and/or required XPostFacto to running 10.4.x and/or 10.5.x in the first place. (exception: Pismo, see above). It may be also possible to add support for G4-upgraded PowerMac 8500s and other pre-G3 PowerMacs. Macs with G3 (or lower) CPUs will most certainly be ruled out here (i.e. the original PowerBook G3 or iBook G3). Initial patches to set up working installer media Once you have created an installer (for now, this would be the 10A96 Server edition) on a bootable drive (either FireWire or USB for [PPCs which are able to boot from USB]), get the 10.6PPC archive and either use the script 10.6 PPC.sh (which you will need to adapt to your volume name prior to running it), or copy the kexts to the correct Extensions folder on your installer drive. Check and correct the file permissions to root/wheel xxx x-x x-x via chown/chmod terminal commands, or use the great handy tool, BatChmod. This shell script will patch the installer to boot properly: https://github.com/julian-fairfax/osx-sl-patcher Also, the file OSInstall.mpkg must be copied to /System/Installation/Packages (delete/replace original package there). Be sure to verify the file permissions for that, as well. This is all best done with a more recent OS, but generally it should be feasible to do on a PPC running Leopard. (Have not tried this and done it on Catalina.) If all is done right, then this installer volume should be bootable on G4/G5 machines! 10.6_snowleopard_10a190_clientdvd.iso(7533.72 MiB / 7899.68 MB) / ISO image 56 / 2020-05-01 / 65097453a0b028293a41067b4e0b7d9f8bc14efc / / PPC_SL_10A190.dmg(3254.47 MiB / 3412.56 MB) Bootable DMG image of an installed system / DMG image 59 / 2020-05-13 / 3b4b1504373ea8f29c99b9f3bb7933348fb7527b / / Architecture Universal Binary Emulating this?
