More on Photoshop 5.5/Altivec Bug: I've updated my earlier post on the Photoshop 5.5/Altivec bug with disturbing info from a Yikes G4/400 owner that states his system didn't have the problem until he overclocked it to 450MHz.
So far the systems that have the problem (verified here) are 450MHz G4s. As I noted earlier
- I had hoped this was not related to the G4 errata (which was the reason for delays in 500MHz G4s) but now I wonder. I cringe at the thought that the G4/450's CPU errata may be responsible for these image problems but let's wait until more is known about the issue before assuming the worst.
QT Out of Date Fix: A reader responds to the reader request earlier today (now removed) asking how to fix the 'QT components out of date' startup error message:
"I had the same problem with this error message. I'm running a beige G3 266 minitower w/ 8.6 (if that makes any difference) I downloaded the stand alone full installer from apple's website... http://www.apple.com/quicktime/download/support/ The Game News page has an update from Graphic Simulations on Mac Descent 3 status. Remember to support companies that make Mac games to let them know there is a Mac market for quality games like Descent 3. See my article on programmer Duane Johnson and Descent 3 for an example of the amazing graphics in the game.
Apple G4 Software DVD Player Tests in non-G4 Macs: Many readers have asked recently if the Apple G4/AGP system's software DVD player will work in other Macs (with a DVD ROM drive of course). As a test I installed a retail Rage128 Orion PCI graphics card in my B&W G3 with DVD drive (removing the OEM Rage128 with mpeg piggyback card). I copied over the G4's DVD player and DVD extensions (requires DVDruntimeLib extension as well as the Region and Navigation manager). The software DVD player would not work however, reporting the player was "not compatible with this machine". (A reader correctly noted that since the player works on an iMac DV system, it must check for a system ID, not a G4 CPU.) As noted in yesterday's news, the player requires an ATI card to even run in the G4/AGP system. It did work with a PCI Rage128 Orion (retail) card so an AGP graphics card is not required.
ATI VR 128 Status: [Update: Deanna Perkins of ATI just confirmed they have shipped cards to distributors and that all backorders should be filled in the next few weeks.] I almost hate to mention it without a dealer confirming they are arriving - but the latest info I have is that Mac Rage128 VR cards are shipping to dealers now (see ATI's Pricing Page). If anyone gets one or finds one in stock (really) let me know.
I updated the post on the PS 5.5/Altivec bug with a sample image showing the unwanted color bars seen in a JPEG file after applying the Twirl filter.
Photoshop 5.5/Altivec Bug: A reader notes an odd problem with the Altivec G4 extensions enabled (see the update below for the latest feedback on the problem):
"Mike, I tested this here on my G4/450 with PS 5.5 and saw the problem with the 'twirl' filter (horizontal color bars in the image - see sample). I hope this is just a Photoshop bug (or video driver issue) and not due to G4 chip errata.
"Mike,
"You may not be aware but Adobe has posted Premiere 5.1c and a new device control plugin. This was to address issues concerning the inability of G4 systems and OS 9 - to use Premiere to import/export DV video to Digital camcorders. If any readers have a solution, please contact me. While on the subject, iMovie/iMac DV owners might want to check the tips on the Apple iMovie Gear page that has workarounds for some Firewire Camcorder problems by brand name and model.
"Hi Mike, I welcome feedback for readers on how well this works (especially in OS 9) to perhaps get back some of the lost performance readers are noting in applications and benchmarks.
Also note that as mentioned by Promax and in my TurboMax IDE card review, audio/video playback issues (dropouts/stuttering) will occur with IDE drives connected to the card if it is installed in pre-Apple G3 systems. There is no known fix for this if the card is used in other than Beige G3 or later systems.
Yikes ROM Update: A reader scolded me (in fun) for missing the fact Apple posted a Power Mac G4 ROM 1.8.1 update yesterday. This update is for PCI based G4s only and is said to fix data or file corruption with Virtual Memory on and Photoshop crashes when Extensis Photo Tools are installed. The lower sidebar here has links to Apple's Software updates and TIL updates pages every day, but I was very busy yesterday (off the net) and missed it.
Speaking of DVD, I'll be testing the G4's Software DVD player in a B&W G3 with Rage128 Orion card today (no mpeg card on the retail Rage128). I suspect the player requires a G4 CPU, but will verify this since many readers are asking. Remember that as mentioned here previously, there is a shareware Mac Software DVD player (beta) at http://fred.elma.fr/Soft_DVD/soft_dvd.html. This is noted in the FAQ's DVD topic area for future reference.
"Mike, I installed CPU Charger on my 132mhz PM 9500 (I know, an upgrade card is pending :o) running OS 8.6. And with mutliple apps active, yes there is a noticeable improvement in the front application's performance - most notably if it's a graphic intensive program. However I ended up disabling the Init.
"OpenGL 1.1.1 and later will not work with ATi drivers designed for OpenGL 1.0 (such as 4.0.1). The converse is also true. I am guessing you used 4.0.1 since Mac OS 9 does not install drivers for the Rage Orion card. To fix this problem you will have to get OpenGL drivers for OpenGL 1.1.1" Owners of retail ATI cards should watch for updates at ATI's web page. Note that Apple G4 systems with OS 8.6 also ship with OpenGL 1.1.1 installed.
For a blast from the past see what was on the front page news here one year ago. Monday's News Summary

The recent features page has a lists reviews/articles you may have missed. For a guide to finding answers to questions - see my Site Guide page. Considering a G3 Upgrade? Check the CPU Upgrade Owner's Survey results and search for owner reports by Mac model and/or card brand. Readers post new entries daily and the database is updated several times a week. I urge any owners that have had problems to report this via the Survey Form. Always give the most weight to recent owner reports (dated in the listing) as in many cases problems are later found to be due to settings errors, slow L2 cache, etc. Note: Before sending tech support related questions please check the Answers to Common Questions, Troubleshooting page, Site Contents, CPU Card reviews/articles, SCSI reviews articles, Graphics card reviews, Tips/Misc, Message Boards and Help pages - in many cases the answers to your questions are there and they have far more detail than I can list in an email. For Apple G3 system info - see the G3-ZONE. Please try the Men in Mac Help page as an alternative on requests for tech support to help me be able to spend more time on reviews and getting caught up in mail. Thanks. |
