Giving the necessary detail about system requirements in the description is what I do when different uploads have different requirements. You have made the right decision. Sometimes it can be better to make another page, but in this case DL #1 contains both v. 3 and 4 so the simplest thing is to retain a single page for the present.

After seeing the title of this post, it seemed like the appropriate place to upload a 3.21 version I found, so I did. However, it now seems like maybe it should be its own post? The originally-uploaded CD contains both OS 9 and OS X versions but was tagged in the download section as OS X. Mine is OS 8.6-9.2-only. In the “#1” and “#2” downloads section top/right, I don’t see a way to specifically define OS requirements PER UPLOAD SHARE, only PER PAGE. And, in this case, the docs indicate the 3.21 entry OS requirement is 8.6, but there’s no specific tag for that OS. All uploads look as if they’re 8.5-OS X compatible when they’re individually not. I tried to be very explicit in the body copy to combat these limitations and avoid confusion. Please advise and I’ll move it if necessary!

Its all activated on my G5 running 10.5.8. Check the peak 4.dmg, eveything you need is in there. Make sure you choose a name when doing the activation.

Bummer! No serial or authorization code

Yep. I think I will move all useful informations about version 2.5 on the other page & remove them here. I will let only version 4 & modify this page to follow the presentation...

[EDIT] Done ! All the informations have been moved to the other page. Now, this one only concerns Mac OS X compatible machines.

Didn´t see the BIAS Peak page either.
Lets see what we can make of it. Maybe add the installer and seperate v. 4?

Thanks for making something useful out of the page MacTouch!
I looked at the Peak 4 dmg and it works with Rosetta in 10.6.8.
Also there is a 3.2 installer (PPC G4) included.
Sadly 3.2 crashes my SheepShaver setup and the host. ASIO drivers are the likely culprit.

A serial is included, but the activation code is invalid.
The 14 day trial is possible still.

Hi 24bit,

I have found a version 2.5 of Peak on Internet. It seems to works only on PPC platforms. Should I upload it & modify also the page for ? BIAS ceased business in 2012...

If you have a copy, please upload.
If it should not match the ten year rule, it may still live on the sever hidden.
Maybe themacmeister can shed some light on this page?

Was this from BIAS also? It seems Peak was bundled with several early versions of Final Cut Pro (2, 3, 4, not sure about FCP1)
