Updating imac g5 from safari
There seem to be five factors involved here: CPU speed, G3 vs.G4, graphics processor, screen settings, and operating system.He also suggests that sometimes it’s possible to massage a dead pixel back to life.Dan From Brian Troisi: At Beta Macs, there is a model for 9 with a 12″ screen, 1 GHz G4, 256 MB RAM, 30 GB hard drive, Combo drive, and Air Port Extreme.Hard drive speed and system memory don’t seem to be factors, and as long as you have broadband, that shouldn’t be an issue at You Tube resolution.On most Macs, it’s not possible to change the CPU, CPU speed, or graphics processor, so for the best video playback on older Macs, my recommendation is OS X 10.3.9 and dropping your screen resolution to 800 x 600 or even 640 x 480 (on a notebook, stick with the native screen resolution).Also try switching from millions of colors to thousands.Even with Safari, the 400 MHz i Mac handles You Tube much better in Safari when set to 640 x 480 and thousands of colors. Macworld appeared in January and I realized I could discuss the issue with someone at the Samsung booth.
The Pith Helmet adds some basic but powerful content filtering to Apple's Safari browser.
They all have trouble running video, like say You Tube. Compared with my dual 1 GHz Power Mac G4, which is very smooth, the 450 MHz dual seems to be running at a lower frame rate under Tiger. I’m guessing that Tiger just draws too much CPU power for a G3 to handle these videos well. It occurs to me that You Tube videos are done using Flash, which may not be nearly as optimized for older Power PC Macs as Apple’s own Quick Time codec.
If anything, it seems a bit smoother in 10.3 Panther, which makes sense, since Tiger uses more CPU cycles for system tasks. On to Panther, which tends to have a lower CPU load. Okay, time to set up the 400 MHz i Mac G3 with 512 MB of RAM, the slowest i Mac to support watching DVDs, with an external Fire Wire drive, which will let me boot the same three operating systems. Off to i Tunes, where I viewed the streaming trailer for Kung Fu Panda on the i Mac at “full size” (press to keep i Tunes from scaling to full screen, which further taxes the CPU).
I also viewed the Kung Fu Panda trailer on my dual 1 GHz Power Mac G4, and it handled everything up to 480 HD beautifully.
The 720 HD version was acceptable, but I didn’t dare try the 1020 HD version.
