You should look into something like True RTA. Hard to beat for 100 bucks.

We have a few of these Sound Technologies analyzers at my job.Some have balanced in and outs and some are unbalanced in and out.These units are completely unsupported but we still find them to be highly useful.Very rugged and built like brick shithouses.
Oh yes
I have never owned a ST one but I do have a Tektronix 4084 and an HP8903b and they are both great units..I do use a ST low distortion oscillator with the tektronix because I couldn't find a cheap enough Textronix one to go in my mainframe.I do have a tektronix function generator but those have a higher distortion product that adds to measurements. That's why I really the HP,It has a sweep on it and an oscillator built right in.
Pete Millet has great software but not for MAC.

I really like the "Soundcard Calibration" feature of that software. That function is also referred to as "normalization," and it allows removing all the response issues from the system before making a frequency response measurement. I use the free version ARTA for audio work, but I haven't figured out how to normalize it yet. As a result, response measurements are pretty tedious. Difficult to believe they would leave this out, the program does virtually everything else you could ever want...

The free version of ARTA allows for soundcard calibration.
Check the manual starting at section 1.5/page 19.
Are we talking about the same thing? By "calibration," I mean frequency response compensation. There's no button to click in this program to normalize (flatten) the response. That's how it should be done.

Is there a Mac version? The website suggests not.
and haven't since 2007..I think our only option for us Apple users is to go with a USB sound card but and I have found a couple that are 130db S/N and 4 or 5 digit distortion..You can't really run an amp in at full power unless you pad it but then I question the accuracy of the power reading..They work well on preamps tho.

My wife has a broken down PC laptop. Maybe I can talk her out of it.
I did a search on Mac-related products. There are many to choose from, but like you say, there's also a learning curve.
Lew
The learning curve isn't too bad..You are a smart guy so I know you can figure it out.
