Yep, it's a good piece of software. I've been using that for about 3-4 years or so,..works well. The same happens if you "make" a Fusion Drive yourself (or Core Storage Drive which is more the "Real" technical name). It does the same thing. Install that programs, and it works well to control the fan noise. Well worth the money for it :)) (and a "home made" Fusion Drive works well, as you then get the same benefit of space, but with the benefit of the behind the scenes SSD,….very useful).
Glad you saw the benefit of the software though,…you'll keep in your arsenal for useful software for quite some time :)) Can never have enough space,…or good software,….lol ;)) Kind regards Daniel --- Daniel Kerr MacWizardry Phone: 0414 795 960 Email: <daniel AT macwizardry.com.au> Web: <http://www.macwizardry.com.au> **For everything Apple** NOTE: Any information provided in this email may be my personal opinion and as such should be taken accordingly, and may not be the views of MacWizardry.
