Guest ѕиоѡ Posted January 24, 2009 Share Posted January 24, 2009 Confirmed: replacing QuickTimeComponents.component works Replace this file inside System/Library/Quicktime Thx for the fix amigos! UPDATE: replacing the component renders Wiretap Studio useless (since it uses QT to encode/decode) so this is a bad fix. I replaced the component again with the 7.6 and app works again.

paduck Posted January 25, 2009 Share Posted January 25, 2009 I had no problems with Quicktime prior to the 7.6 update, then the dreaded lagging mouse issue came about. Replacing: /System/Library/Quicktime/QuicktimeComponents.component with a prior version from Time Machine solved the problem. Interestingly, I guess Time Machine doesn't let you drill down into packages or I would have been a little more surgical. Prior to replacing the file, I tried re-adding the EFI string for the video card, but no joy. This does bring up the question: what happens when you have software the requires features only available in 7.6? Do you have to upgrade your graphics card? I suppose if Apple upgrades their video drivers, then that might help remove the conflict... Link to comment Share on other sites More sharing options...
iamhappy Posted January 25, 2009 Share Posted January 25, 2009 Same here: After installing 7.6 -> jerky mouse while Itunes or QT opened. Replacing the .component file with the old one... seems to work so far. - no jerky mouse with 7.5.5 .component UPDATE: ScreenFlow is not working anymore. Crashes at start I replaced the 7.6 QuicktimeComponents.component file in /System/Library/Quicktime/ with the one provided here in the thread. Even changing back to the original 7.6 .component +repairing permissions will result in permanent crashes. But there is no error displayed in console.

mattrb Posted January 25, 2009 Share Posted January 25, 2009 I used munky's method and I dont get quicktime lag. This is a distribution issue, tested the result myself. Got lag on leo4all and iPC. Also take note of the fact that the distro's cant handle non-apple 8800gt rom's. This will not happen with munky, at least in my case. Link to comment Share on other sites More sharing options...
truefranco Posted January 25, 2009 Share Posted January 25, 2009 This fix will break iMOVIE ,tested by my self ,replased quicktime.component for older version and mouse lag gone but then iMOVIE do not export any video with audio include ,so we need a better fix Link to comment Share on other sites More sharing options...
cmdshft Posted January 26, 2009 Share Posted January 26, 2009 I'm not sure it would even boot... But then again, I could be wrong. It will boot because we can use the card natively in Windows on a MacPro. Link to comment Share on other sites More sharing options...
quetzalcoatl2435 Posted January 26, 2009 Share Posted January 26, 2009 Can you confirm that the card's BIOS is the same as those used in normal PCs? I wouldn't say that just because it works with BootCamp, it would work with a normal PC. If the cards used in Mac Pros are the same "generic" cards as the ones used in PCs, then this whole Quicktime-lag problem would need a different approach...

Guest ѕиоѡ Posted January 26, 2009 Share Posted January 26, 2009 Well, in between the lines I noticed some peeps with real macs have the same issue so it might be apple related. I'm sure there will be an easier fix then flashing the card pretty soon but this also means that we can't update vanilla style anymore and after all, thats why we bought our new hardware. It's a shame but it had to happen sometime right. Good luck with flashing guys Link to comment Share on other sites More sharing options...

InteliMac Pro Posted January 26, 2009 Share Posted January 26, 2009 I could be wrong but i seem to recall that the difference is mac cards have a 128 bit ROM chip, whereas off the shelf PC cards only have a 64 bit ROM chip. This is why Mac Pro's require Apple upgrade kits. When I upgraded the card in my Cube to a 6200 I had to send it to a guy to have it physically modded to a 128 bit chip and flashed. Then again i could be just talking out of my hiney Link to comment Share on other sites More sharing options...

Then again i could be just talking out of my hiney No your not although it depends on the manufacturer some like the eVGA that I have do put the 128k ROM on the board so as a result this card is a favorite among the Mac crowd looking for a cheap upgrade, from what I have read on the Mac Rumors site there has never been a problem flashing one of these cards.

I have an eVGA e-GeForce 8800GT p/n 512-P3-N801-AR depending on the model of Mac Pro your brother would need either the 32 or 64bit ROM to flash with I have included links to both threads. http://forums.macrumors.com/showthread.php?t=434092 http://forums.macrumors.com/showthread.php?t=471227 Link to comment Share on other sites More sharing options...
