I'm seeing a common Mac OS Catalina (10.15.6) fault with accountsd/deleted and Siri? It seems to be extremely serious! Does anyone know the cause or solution for this? My computer seems to be overheating a lot and has very very high CPU usage!? Is this because of overheating or something else with Siri and a demon? (Side question: what combination of CPU speed, RAM, and video card is necessary for any Mac running OS X to be a speed demon? Does such a machine truly exist?). Five run Mac OS X, one runs.

Rating: 5/5 Easy installation transformed by 2008 iMac to a speed demon January 29, 2018 Like the review summary notes my old out of date early 2008 iMac was transformed to a speed demon, no more waiting for the 320GB hardwire to spin and start up locating files and opening applications. I would recommend this item to a friend! There might be RAM speed differences, there might be hard drive performance differences, and there definitely was a pronounced OS difference: the Quadra 660AV is running Mac OS 7.6.1 while the Mac SE is running Macintosh System 6.0.7.

A quote from the article:

'Sporting the most powerful Intel chip currently available in Apple's lineup, the 15-inch, 2.16 GHz dual-core MacBook Pro is, simply, a speed demon. There has never been a Mac laptop this fast. It's so fast, it even outpaces professional workstations in several key benchmarks. What's more, with its ability to run both Mac OS X and Windows operating systems, it's two computers in one. There has simply never been a better time to buy an Apple notebook computer.'

Speed Demon (brendan A.) Mac Os 8

I’ve been using Classic Mode on G4 Power Macs for years, but now I have a 2.3 GHz Power Mac G5 with dual processors. It can’t boot Mac OS 9 natively, but it can run Classic Mode. How fast is it?

One beautiful thing about dual-processor Macs is that they can fully dedicate one CPU to Classic Mode. If you run Classic on a single processor machine,there can be times when it can tie up the entire machine, something I used to run into when uplading site changes using Claris Home Page.

Time to pull out the old benchmark tests!

Speedometer 3

The base machine for Speedometer 3 is a Mac Classic with 2 MB of memory, the original 40 MB hard drive, and System 6.0.7, which rates 1.0 on the basic tests. (KWhetstones and Dhrystones are absolute numbers.) This predates PowerPC Macs, so the code is native 68k only.

  • CPU: 876.00
  • Graphics: 121.48
  • Disk: 1517.00
  • Math: 2054.24
  • Overall: 895.67
  • KWhetstones: 30,000/sec
  • Dhrystones: 600,000/sec

My fastest points of comparison are a 266 MHz Beige Power Mac G3, which scores 134.8 on the CPU test and 637.9 on math, and a 233 MHz iMac Revision B, which achieves a 69.1 score in graphics and 13.3 on the disk test. These are obviously a far cry from what a dual processor system running at roughly 10x the clock speed can provide.

Speedometer 4

For Speedometer 4, the base machine appears to be a Quadra 700 or Centris 650, both 25 MHz 68040 Macs that nominally rate 1.0 on most tests. Speedometer 4 supports both 68k and PowerPC Macs natively.

  • CPU: 81.02
  • Graphics: n/a
  • Disk: 5.038
  • Math: 39087.5
  • KWhetstones: 803,213/sec
  • Dhrystones: 2,147,483/sec.

The last (and fastest) Mac I tested using Speedometer 4 was a Digital Audio Power Mac G4 upgraded with a G4 running at 1.53 GHz. It’s CPU score was 93.4-93.7 depending on OS, easily outperforming the Dual G5. Its disk score or 4.8-4.9 nearly ties the G5, but it’s math score is just 10% of what the G5 provides.

My long-gone 400 MHz PowerBook G4 running Mac OS 9.2.2 natively scored 30.6 on the CPU test, 3.35 on the disk test, and 1124.6 on the math test. Such a low clock speed, yet the CPU scores almost 38% as fast as a 2.3 GHz G5 – that’s shocking and perhaps indicates an issue with the benchmark test itself.

MacBench 5

In MacBench 5, the reference system is a 300 MHz Blue & White Power Mac G3, which scores 1000.

  • Processor: 5015
  • Floating Point: 6095
  • Disk: 12118

For comparison, my 400 MHz PowerBook G4 running Mac OS 9.2.2 natively scored 1282 on the Processor test, 1519 on Floating Point, and 457-2237 depending on hard drive and cache size in the Disk test.

I ran MacBench 5 on that 1.53 GHz upgraded Digital Audio Power Mac G4. When natively running Mac OS 9.2.2, it scored 3714 on CPU, 3773 on math, and 3508 on disk, all of which the Power Mac G5 handily beat.

SpeedRun PPC

I have lots of more up-to-date results for SpeedRun PPC, which was written specifically for PowerPC Macs in the Classic Mac OS era. All supplied results are for machines booting Mac OS 9.2 natively. I had to set graphics to thousands of colors; the other benchmarks were all run in standard millions of colors mode.

Here’s how the Dual 2.3 GHz G5 scores:

  • Graphics: 1156
  • Harddrive: 1481
  • Processor: 803
  • RAM: 4444
  • Overall: 1971

If you think that sounds impressive, it does, but there is one instance where an older, slower G4 Power Mac outperform it. On the Graphics test, a 1.0 GHz Dual Quicksilver 2002 hits 1273. The 867 MHz Quicksilver comes close on the Harddrive test, scoring 1365 – not too far behind my Dual G5.

The Power Mac G5 wins handily on overall performance, with a score of 1971. That dual G4 reaches nearly 75% of that performance at 1416, indicating that a dual 2.3 GHz G5 system is nowhere near as much faster than a dual 1.0 GHz G4 Mac than processor speed would lead you to expect.

Conclusion

This 2.3 GHz Power Mac G5 with dual processors is a very nice machine, and the fact that it runs Classic Mode is wonderful. It’s no speed demon by today’s standards. Even the earliest Core Duo Macs introduced in 2006 have more power. But they can’t run Classic Mode, and this is one of the fastest Macs than can (the dual 2.5 GHz, dual 2.7 GHz, dual-core 2.3 GHz, and quad-core 2.5 GHz G5 Power Macs are the only faster PowerPC Macs).

No, the G5 is not a much superior to the G4 as clock speed would predict, but overall it does provide superior performance to the other Macs I’ve tested using Classic Mode. I suspect a 1.25 GHz dual-processor Mirrored Drive Door might give it a run for its money, and it’s possible the 1.42 GHz FireWire 800 model could outperform this G5 overall, but those tend to still command a pretty premium price.

If you need good Classic Mode performance, check your local Craigslist. You may well find a bargain like mine for under $100 – sometimes half that. And you do want to buy locally; these big, heavy beasties cost quite a bit to ship.
