*Know Your Mac’s Upgrade Options, Phil Herlihy, The Usefulness Equation, 2008.08.26. Any Mac can be upgraded, but it’s a question of what can be upgraded – RAM, hard drive, video, CPU – and how far it can be upgraded.
*The Future of Up-to-Date Browsers for PowerPC Macs, Charles W Moore, Miscellaneous Ramblings, 2009.08.31. With Intel-only “Snow Leopard” shipping, software support for PPC Macs will continue its decline. Also, a look at SeaMonkey 2 and Camino 1.6.9.
*Optimized Software Builds Bring Out the Best in Your Mac, Dan Knight, Low End Mac’s Online Tech Journal, 2009.06.30. Applications compiled for your Mac’s CPU can load more quickly and run faster than ones compiled for universal use.
*Tips for Installing or Reinstalling Mac OS X 10.4 Tiger, Adam Rosen, Adam’s Apple, 2009.06.10. Mac OS X 10.4 uses less memory than Leopard, supports Classic Mode on PowerPC Macs, and, unlike Leopard, is supported on G3 Macs.
*PowerPC Architecture Was Not a Failure, Dan Knight, Mac Musings, 2009.02.16. CNET’s Brooke Crothers calls PowerPC a failed architecture, but 12 years of PowerPC Macs, IBM’s blade servers, and three game consoles tell a different story.
*The ‘Better Safe Than Sorry’ Guide to Installing Mac OS X Updates, Charles W Moore, Miscellaneous Ramblings, 2008.12.16. Most users encounter no problems using Software Update, but some preflight work and using the Combo updater means far less chance of trouble.
*Why You Should Partition Your Mac’s Hard Drive, Dan Knight, Mac Musings, 2008.12.11. “At the very least, it makes sense to have a second partition with a bootable version of the Mac OS, so if you have problems with your work partition, you can boot from the ’emergency’ partition to run Disk Utility and other diagnostics.”
*Will Snow Leopard Support Some PowerPC Macs?, Simon Royal, Tech Spectrum, 2008.11.26. It just doesn’t make sense that Apple would ship a new OS that won’t support Macs sold less than three years ago.
*Leopard runs very nicely on PowerPC Macs, Simon Royal, Tech Spectrum, 2008.11.19. Some claim that Mac OS X 10.5 is so optimized for Intel Macs that it runs poorly on PowerPC hardware. That’s simply not the case.
*The future of PowerPC Macs and software as ‘Snow Leopard’ approaches, Simon Royal, Tech Spectrum, 2008.11.13. Apple phased out Classic Mode and G3 support with ‘Leopard’ last year, and next year’s OS X 10.6 won’t support any PowerPC Macs. Will other developers abandon PowerPC as well?
*How to clone Mac OS X to a new hard drive, Simon Royal, Tech Spectrum, 2008.10.07. Whether you want to put a bigger, faster drive in your Mac or clone OS X for use in another Mac, here’s the simple process.
*Tiger vs. Leopard: Which is best for you?, Simon Royal, Tech Spectrum, 2008.09.22. Two great versions of Mac OS X, but unless your Mac is well above the minimum spec for Leopard and has lots of RAM, stick with Tiger.
*Apple Trumps Microsoft in Making the 64-bit Transition Transparent to Users, Frank Fox, Stop the Noiz, 2008.09.18. To use more than 4 GB of RAM under Windows, you need a 64-bit PC and the 64-bit version of Windows. On the Mac, OS X 10.4 and later already support it.
*SATA, SATA II, SATA 600, and Product Confusion Fatigue, Frank Fox, Stop the Noiz, 2008.09.08. In addition to the original SATA specification and the current 3 Gb/s specification, SATA revision 3.0 is just around the corner.
*Does running OS X system maintenance routines really do any good?, Charles W Moore, Miscellaneous Ramblings, 2008.08.26. Mac OS X is designed to run certain maintenance routines daily, weekly, and monthly – but can’t if your Mac is off or asleep.

*Do matching pairs of memory make the iMac G5 go faster?, Bare Feats, 2004.10.27. Although matching pairs benchmark up to 29% faster, real world tests show no significant difference in performance.
*The iMac List, an email list iMac users
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 G5Mac Os X 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.Mac Os For Imac G5 5590
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 OptionsHard Drives and SSD
All G5 iMacs support one internal SATA hard drive.

*Why You Should Partition Your Mac’s Hard Drive, Dan Knight, Mac Musings, 2008.12.11. “At the very least, it makes sense to have a second partition with a bootable version of the Mac OS, so if you have problems with your work partition, you can boot from the ’emergency’ partition to run Disk Utility and other diagnostics.”
*Will Snow Leopard Support Some PowerPC Macs?, Simon Royal, Tech Spectrum, 2008.11.26. It just doesn’t make sense that Apple would ship a new OS that won’t support Macs sold less than three years ago.
*Leopard runs very nicely on PowerPC Macs, Simon Royal, Tech Spectrum, 2008.11.19. Some claim that Mac OS X 10.5 is so optimized for Intel Macs that it runs poorly on PowerPC hardware. That’s simply not the case.
*The future of PowerPC Macs and software as ‘Snow Leopard’ approaches, Simon Royal, Tech Spectrum, 2008.11.13. Apple phased out Classic Mode and G3 support with ‘Leopard’ last year, and next year’s OS X 10.6 won’t support any PowerPC Macs. Will other developers abandon PowerPC as well?
*How to clone Mac OS X to a new hard drive, Simon Royal, Tech Spectrum, 2008.10.07. Whether you want to put a bigger, faster drive in your Mac or clone OS X for use in another Mac, here’s the simple process.
*Tiger vs. Leopard: Which is best for you?, Simon Royal, Tech Spectrum, 2008.09.22. Two great versions of Mac OS X, but unless your Mac is well above the minimum spec for Leopard and has lots of RAM, stick with Tiger.
*Apple Trumps Microsoft in Making the 64-bit Transition Transparent to Users, Frank Fox, Stop the Noiz, 2008.09.18. To use more than 4 GB of RAM under Windows, you need a 64-bit PC and the 64-bit version of Windows. On the Mac, OS X 10.4 and later already support it.
*SATA, SATA II, SATA 600, and Product Confusion Fatigue, Frank Fox, Stop the Noiz, 2008.09.08. In addition to the original SATA specification and the current 3 Gb/s specification, SATA revision 3.0 is just around the corner.
*Does running OS X system maintenance routines really do any good?, Charles W Moore, Miscellaneous Ramblings, 2008.08.26. Mac OS X is designed to run certain maintenance routines daily, weekly, and monthly – but can’t if your Mac is off or asleep.

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 G5Mac Os X 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.Mac Os For Imac G5 5590
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 OptionsHard Drives and SSD
All G5 iMacs support one internal SATA hard drive.
