Is it safe to try and put 10.4.7 on my new macbook?

[amycishere]

I keep on having audio feedback problems in imovie with the isight camera. People have said 10.4.7 didn't have this problem. I have had 10.4.8 and 10.4.9 and the problem persists. Can I update to 10.4.7 successfully not? Do I need to back up my hard drive?

It seems like the people who have the worst problems are those that worry a lot about a simple software update that millions of people do in five minutes without problems or even thinking about it.

Going from 10.4.9 back down to 10.4.7 (called a downgrade) is essentially impossible. You have to start over again from 10.4.7 or something lower than 10.4.7, find the 10.4.7 upgrade, and install that manually.

If your computer shipped with something greater than 10.4.7, then it is extremely unlikely you will ever be able to achieve this lower version number.

I'm assuming you've spoken to the Applecare folks about this? They might be able to provide some assistance to you that is more specific that anecdotal discussions that 10.4.7 might not have the problem.

There could be a more serious issue (hardware related) that might be resolved by talking to them.

Ok, thanks.

Oh, yes, have spent over 2 hours. In 10.4.8 the imput/oput volume had to be about at 27% or using isight in imovie would cause a very loud beep. Now with 10.4.9 I can have the imput and output at 49% with no beep but anything louder causes a big beep again.

So based on that, in 2 more updates you'll pretty much be up to full volume

Seriously, though, this sounds more like a hardware issue. Are you near an Apple store?

 

[juanster]

sounds like hardware to me too

They actually declared my first macbook DOA because of the same issue and the replacement they sent has the same issue so the product specialist says it must be a software issue.
