Mondoslug Posted October 13, 2006 Share Posted October 13, 2006 Hi, excuse my ignorance. I just got a Mac Pro & immediately upgraded the firmware just because and then installed Boot Camp. Is there a way to go back to the previous firmware if I choose? Been years since I owned a Mac. Does it involve a clean install or something & will I need to re-partition & install XP again since the Mac Drivers disc was created after the updated firmware tweak? TIA!

asap18 Posted October 13, 2006 Share Posted October 13, 2006 why would you need to revert back to the old firmware? Link to comment Share on other sites More sharing options...
Mondoslug Posted October 13, 2006 Author Share Posted October 13, 2006 Hi, thanks. I don't know that I need to. I found a thread on a Digital Audio forum and was just curious. It's specific an audio app Pro Tools which can be finnicky at times. This is the post below. Not necessarily the gospel but I was just wondering how you do it anyway. Thanks for the rply >>>DON'T update the firmware if you're not updating to OS 10.4.8!! 10.4.7 runs waaaay slow with the new firmware. PT will run, allright (it runs pretty much on the card, right?), but every little drop-down menu is a drag... Repeat do NOT install new firmware on your intel-based mac if you're not updating the OS. Btw. PT HD is 'not tested' with OS 10.4.8, but maybe somebody tried it?<<< Link to comment Share on other sites More sharing options...
lord_muad_dib Posted October 13, 2006 Share Posted October 13, 2006 so.. why you shouldn't upgrade to x.8? Link to comment Share on other sites More sharing options...
hatoncat Posted October 16, 2006 Share Posted October 16, 2006 To answer the original question, no, Apple does not permit firmware downgrades. Apple does have a firmware recovery disc. That disc will revert your firmware to the older version, but only if the firmware update was not successful. It is available at http://www.apple.com/support/downloads Link to comment Share on other sites More sharing options...
ConMan Posted October 17, 2006 Share Posted October 17, 2006 Here's one reason not to do the firmware upgrade: (I've attached a screen shot--hopefully it worked.) Bummer. And that restoration CD--no dice. Works only if you didn't "successfully" run the upgrade. I was kinda hoping you guys would know of a way to downgrade, but from what I've read, it looks like I'm outta luck. Guess I'll be shipping it back to Apple to let them fix for me. Sigh... what a sad first post for me. :-( Link to comment Share on other sites More sharing options...
hatoncat Posted October 17, 2006 Share Posted October 17, 2006 Right... exactly what I said above. I don't see anything wrong with the screenshot, leading me to think you have a non-firmware hardware issue. Such issues can manifest due to the process of a firmware update, but have nothing to do with the firmware code itself. Regardless, there is no reason to downgrade firmware. Apple only makes changes that need to be changed. If there ever is a "firmware bug"... Apple will quickly issue an updated firmware to patch it.

ConMan Posted October 17, 2006 Share Posted October 17, 2006 Hmm. Wow--you're right. I just checked the posted screenshot on my PC, and everything looks fine. Well, suffice to know that on my MacBook the colors, hues, and contrasts are so out of sync that it is nearly impossible to use the computer.

hatoncat Posted October 17, 2006 Share Posted October 17, 2006 Please search, the color change was prompted by the Mac OS X 10.4.8 update. If you have a more extensive color shift than that, contact AppleCare. Link to comment Share on other sites More sharing options...
brbo Posted October 23, 2006 Share Posted October 23, 2006 firmware restoration CD won't let you restore firmware to original factory state. maybe we will have to wait for next firmware update, deliberately corrupt the firmware in the process of upgrading and then use the firmware restoration cd to downgrade to original firmware. i liked the original firmware best as my macbook was super silent for the most part and not too hot to use it in my lap.

Stadsport Posted October 24, 2006 Share Posted October 24, 2006 As mentioned, the color changes are from 10.4.8. I believe there's a "fixed" color profile floating around. Link to comment Share on other sites More sharing options...
