So, my question is: when specifying system requirements for a
particular
feature (e.g. I'm moving my app towards using a MatrixMixer), which
should I
ask for - Mac OS 10.x, or QuickTime 6.x? Obviously I'll need to check
for
the existence of these features in my code, but I'd like to know what
to say
in my system requirements text too!
The headers should state the actual requirements for particular APIs.
Components in theory could exist on any system, but you can always
check for existence by trying to create one. In particular the Matrix
Mixer requires 10.3 or QT 6.4 (however I believe QT 6.5 fixed some bugs
in it).
I guess that requiring (for example) OS 10.3 implies that the user
will have
(for example) QT 6.5, as that's the distribution of QT which comes
with 10.3
(I think). So is it okay to specify the QT version as the requirement?
10.3 came with QT 6.4, but since QT 6.5 is a free upgrade I see no
reason to not require QT 6.5.
And what about OS X 10.0 and 10.1? I note that the QuickTime version
availability page
(http://www.apple.com/quicktime/download/version.html)
says that the version of QuickTime for Mac OS X is 6.5, but the
downloads
page (http://www.apple.com/quicktime/download/) says you need Mac OS X
v10.2.5-v10.3.x. Can't QT 6.5 (with related CoreAudio improvements) be
installed on 10.0 or 10.1? I'm assuming lots of people are still
using 10.0
and 10.1, given that 10.2 and 10.3 have been paid upgrades.
I believe there is a technote somewhere that states the highest
versions of QT supported on each version of Mac OS X, but no, QT 6.5 is
not supported on 10.0 or 10.1. And the reality is that most users of
10.0 or 10.1 upgraded to 10.2 or 10.3. Most people see very very few
users running on less than 10.2. Additionally, most Audio Units are not
available on 10.1 (since 10.2 introduced the Audio Unit v2 format most
Audio Units are in).
