The PowerPC platform had a long life on Macs. The first Power Macs arrived on March 14, 1994, 10 years after the first Mac – the Power Mac 6100, 7100, and 8100, running the PowerPC 601 CPU at speeds of 60, 66, and 80 MHz respectively. The PowerPC G5 came to the iMac in August 2004, over a decade after that.

The 2004 iMac G5

The G5 iMac introduced a new form factor to the all-in-one Mac. Where early Macs had been cute little boxes with 9″ screens, the first iMacs were curvaceous enclosures with 15″ displays, and the G4 iMacs had hemispheric bases with 15″ to 20″ screens that seemed to float above them, the iMac G5 put all the electronics directly behind the display. Not counting the stand, it was about 2.5″ thick.

The Mid 2004 iMac G5 came in 17″ and 20″ versions, using the same IBM PowerPC 970fx (G5) CPU that had already been used in the first generation Power Mac G5s (June 2003) as well as the second (April 2004). The iMac G5 has a single CPU – 1.6 and 1.8 GHz on the 17″ model and 1.8 GHz on the 20-incher.

Unlike top-end Power Macs that have a memory bus running at half of CPU speed, the G5 iMacs ran their memory bus at one-third of CPU speed, making them a bit less efficient. Here’s how benchmark results compare the August 2005 iMacs with the June 2004 Power Macs using the same speed CPUs:

17″ 1.6 GHz iMac, 842
1.6 GHz Power Mac, 918
17″ 1.8 GHz iMac, 985
20″ 1.8 GHz iMac, 985
1.8 GHz Power Mac, 1047

In each case, the Power Mac G5 has a performance edge over the iMac G5 – 9% at 1.6 GHz and 6% at 1.8 GHz.

By way of comparison to previous iMacs, the 1.25 GHz 17″ iMac G4 scores 631, while the 20″ model comes in at 616. The entry-level 17″ 1.6 GHz iMac G5 has about one-third more power than the G4 it replaced, while the 20″ 1.8 GHz G5 sees a 60% gain in processing power.

Several factors contribute to this improvement. The iMac G5 clock speed is 28-44% faster to begin with. The memory bus runs at 533 or 600 MHz vs. 167 MHz – over three times as fast. The G4 has a 64 KB Level 1 cache and a 256 KB Level 2 cache as part of the CPU plus a 2 MB Level 3 cache. The G5 has a Level 1 cache with 64 KB for instructions and 32 KB for data as well as a 512 KB Level 2 cache on the CPU. There is no need for a Level 3 cache with its faster memory bus.

The 1.5 GB/s SATA drive bus in the iMac is 50% faster than Ultra ATA/100 in the G4, although the drives installed at the factory are unlikely to saturate that bus. All 17″ and 20″ G4 iMacs support up to 2 GB of system memory, as do the first two generations of iMac G5.

Curiously, all G5 iMac use Ultra ATA/133 for their optical drive – faster than the Ultra ATA/100 used for optical drives in the Power Mac G5!

For expansion, the Power Mac G5 has three USB 2.0 ports and two FireWire 400 ports, as well as analog audio-in and audio-out.

As for resolution, all 17″ G5 iMacs sport a 1440 x 900 pixel display, while the 20″ versions use a 1680 x 1050 screen. First generation G5 iMacs use Nvidia GeForce graphics and shipped with OS X 10.3.5 Panther. Bluetooth and AirPort Extreme were optional.

The Mid 2005 iMac G5

Apple moved the iMac G5 speed forward by 200 MHz in May 2005, putting 1.8 GHz and 2.0 GHz CPUs in the 17″ model and 2.0 GHz in the 20″. The new models replaced Nvidia graphics with Radeon 9600 and 128 MB of dedicated video memory.

New to the iMac was the Ambient Light Sensor, which adjusts screen brightness to its surroundings. 802.11g AirPort Extreme and Bluetooth 2.0 were now standard features, as was Gigabit Ethernet.

These were the first iMacs to ship with OS X 10.4 Tiger.

The Late 2005 iMac G5 Gets iSight

Apple shook the Macintosh world by announcing in June 2005 that it would switch from PowerPC chips to Intel x86 CPUs “within a year”. Those of use using Macs were stunned. Apple had long touted the advantages of its PowerPC RISC CPUs against Intel’s x86 architecture. Now it was poised to follow the PC world.

Apple didn’t quit introducing new PowerPC models right away. We assumed the Intel transition wouldn’t take place until May or June 2006. It came months before that in January 2006, but that didn’t keep Apple from introducing one last generation of G5 iMacs in October 2005.

This time there were only two models – a 1.9 GHz 17″ iMac G5 and a 2.1 GHz 20″ iMac G5. New features included a built-in iSight webcam (a Mac first) and 512 MB of system memory on the logic board, allowing for a maximum of 2.5 GB. Graphics were upgraded to Radeon 9600 Pro.

These were the only G5 iMacs with an infrared sensor for use with Apple’s Remote Control, which was included with the computer and designed to control Apple’s new Front Row media center software. The Late 2005 iMac is also thinner than the earlier models.

Operating System

All G5 iMacs can run OS X 10.4 Tiger and 10.5 Leopard, the last version of OS X to support PowerPC Macs.

Tiger runs decently with 512 MB of memory, while Leopard really wants 1 GB. Tiger supports Classic Mode, which allows you to use software that runs under Mac OS 9. Leopard has no support for Classic Mode.

In general, Tiger will run faster than Leopard on PowerPC Macs, but with Leopard you will have access to some newer software that isn’t compatible with Tiger. Unless you need to run something that requires one OS or the other, you should find both run very well on G5 Macs.

My preference is to configured G5 Macs with both, using a smaller partition (perhaps 1/4 of the hard drive) for Tiger and the rest for Leopard. Since there are some more modern browsers for Leopard that are not compatible with Tiger, I usually run Leopard – but should I need it, Tiger is available to me with a restart.

Expansion Options

Hard Drives and SSD

All G5 iMacs support one internal SATA hard drive.

Bear in mind that you cannot use hard drives larger than 2 TB with any PowerPC Mac. This is a limitation of the Apple Partition Map (APM), which is required on any drive that will boot a PowerPC Mac. This applies equally to internal drives, SCSI drives, USB drives, FireWire drives, eSATA drives, and even shared Mac volumes on your network.

For all-out speed, you can use a Solid State Drive (SSD), and its performance will only be limited by the speed of the iMac’s 1.5 GB/s SATA bus. OWC is currently selling it Mercury Electro SATA Rev. 2 SSDs for the following prices:

60 GB, $42.99
120 GB, $64.99
240 GB, $112.99
480 GB, $187.99
960 GB, $344.99

I wouldn’t recommend the 480 GB or larger drive in a G5 iMac unless you had a very specific reason for it. These machines almost always sell for under $100 on the used market.

If you need a lot of capacity, look at 7200 rpm hard drives, which start at about $60 for 1 TB. A 2 TB drive should cost under $100, and that’s the highest capacity a PowerPC Mac can handle.

Memory

We used to say you can never have too much memory, and with memory this reasonably priced, I suggest you just go ahead and do the 2 GB upgrade.

Here are current prices from OWC:

Mid 2004 and Mid 2005 iMacs

1 GB: $17.49
2 GB: $25.79

Late 2005 iSight iMacs

1 GB: $11.99
2 GB: $20.79

And What Will You Do with It?

For word processing and spreadsheets, I’m still a huge fan of AppleWorks. You should be able to pick up a copy of version 6.x for $20 or less on eBay. A good free writing tool is the Bean word processor, which I use for quick writing tasks.

If you’re using Google Docs and Google Sheets at work or school, you’ll be happy to know that you can access your files and work on them from a G4 or G5 iMac and TenFourFox or Aurora.

If you’re a Microsoft Office fan, Office: 2008 is the last version compatible with PowerPC Macs. It runs just fine on these iMacs, although it is a bit bloated – an issue with almost every edition of Office ever released. Used copies are very cheap on eBay, especially the Student &Teacher edition, and you’ll pay about $75 for a fresh copy. Nice if you need 100% Microsoft compatibility, but I’ve survived without it for years.

A decent replacement is LibreOffice, which is no longer being developed for PowerPC, OS X Tiger, or OS X Leopard. LibreOffice 4.0.6.2 is the last version to support Tiger on PowerPC, and version 4.3 is the last for Leopard on PowerPC, but I’ve been unable to find a link anywhere. LibreOffice makes it difficult to find anything except for the latest version on its website. (The current version of LibreOffice requires OS X 10.8 Mountain Lion or later.)

Mac Os X Snow Leopard Imac G5

LibreOffice is a decent free alternative to Microsoft Office, although it is slow to load even on a fast Mac. See Speed Up LibreOffice on Your Mac for tips on getting a bit more performance from this powerful freeware.

Older versions of Photoshop and Photoshop Elements will run nicely, and there is also iTunes included with OS X – an older, less cluttered, more intuitive, nicer to work with reminder of how wonderful iTunes used to be.

Low End Mac will be putting a couple of these up for sale in the near future.

macOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone and other Apple devices. And it’s been built from the ground up with privacy and security in mind.

Featuring all-new, dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display.

Easy to Use When it’s simple to
do
everything, you can do anything.

On a Mac, everything is designed to work just the way you expect it to — from operating it with simple, intuitive gestures to asking Siri to find a file to having your apps automatically update themselves. Whatever you set out to do on a Mac, there’s much less to learn and that much more to accomplish.

The Finder lets you easily browse and organize the files on your Mac — and those stored in iCloud Drive. View files by icons, in a list, or with Gallery View, which helps you quickly locate a file by how it looks. Drag and drop files into folders in the sidebar. And use the Preview pane to see all of your files’ metadata, quickly create .zip files, and share using the handy Share menu.

Dark Mode adds a dramatic look to your desktop and apps that puts the focus on your content. Dynamic Desktop makes your Mac even more beautiful with time-shifting desktop pictures that match the time of day wherever you are. And Stacks keeps your desktop free of clutter by automatically organizing your files, images, documents, PDFs, and more into tidy groups.

Spotlight helps you quickly and effortlessly find what you want, like documents on your Mac, movie showtimes, and flight departure and arrival times. Just type a few keystrokes in the Spotlight search field and autocomplete immediately shows you relevant results.¹

A simple two-finger swipe from the right edge of your trackpad brings up Notification Center — the same one you use on iPhone — where you can see all the alerts that have come in recently. It’s also where you’ll find your Today view, which you can customize with helpful widgets or handy information pinned from Siri searches.

Siri helps you get things done just by using your voice. It also helps you get more things done at the same time. So you can finish your document while asking Siri to tell your coworker that it’s on the way. Looking for the presentation you worked on last week? Just ask Siri.² And with Apple Music, Siri can be your personal DJ and recommend music based on your tastes, and tell you more about songs, albums, and artists.³

Continuity All your devices.
One seamless experience.

Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. And when friends text you — regardless of the phone they have — you can respond from your Mac, iPad, or iPhone, whichever is closest. When you copy text or an image from one device, you can paste it into another with standard copy and paste commands. And with Sidecar, you can extend your workspace by using your iPad as a second Mac display. You can even unlock your Mac with your Apple Watch. No password typing required.

Privacy and Security We believe your data belongs to you. Period.

Everything you do with your Mac is protected by strong privacy and security features. That’s because we build data security into everything we make, right from the start.

Privacy. You trust our products with your most personal information, and we believe that you should be in complete control of it.

iCloud All your stuff on your Mac.
And everywhere else you want it.

Every Apple app uses iCloud — it’s the magic behind the seamless experience you have with all your Apple devices. So you always have your photos, videos, documents, email, notes, contacts, calendars, and more on whatever device you’re using. And any file you store in iCloud Drive can be shared with friends, family, and colleagues just by sending them a link. iCloud Drive also lets you access files from your Mac on your iPhone or iPad. It’s all done automatically. Just like that.⁵

Accessibility We make sure that everyone is able to use a Mac.

macOS comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, providing many features you won’t find in other operating systems. Voice Control lets users control their Mac, iPad, and iPhone entirely with their voice. And features such as VoiceOver, Accessibility Keyboard, FaceTime,⁶ and Text to Speech help everyone get more out of Mac.

Mac Os X Tiger Imac G5

Technology Advanced to the core.

macOS features powerful core technologies engineered for the most important functions of your Mac. Thanks to Mac Catalyst, you can now enjoy your favorite iPad apps on your Mac. With SwiftUI, developers have a simple way to build better apps across all Apple platforms with less code. Create ML gives developers a faster and easier way to build machine learning into apps. And support for virtual and augmented reality lets developers create immersive worlds for you to step into.

Compatibility Need to work with Windows?
Mac does that, too.

With macOS, it’s easy to transfer your files, photos, and other data from a Windows PC to your Mac. Work with popular file types such as JPEG, MP3, and PDF, as well as Microsoft Word, Excel, and PowerPoint documents. And, of course, you can run Microsoft Office natively on a Mac. If you want, you can even run Windows on your Mac.⁷
