Safari Extension for v.6?

@penglish - you're quite welcome! Glad I was able to help clarify things. :)

@Jonathanm1 - of course; it's definitely not rocket science. Nobody wants to pay more than they have to, and "free" is always good.

But perhaps it does require a little further examination. To use your own example, Apple makes its money when you purchase the hardware they sell you; the OSes which run on that hardware (macOS and iOS) are useless without the hardware. That's why Apple can make them "free": because only people who own Apple's hardware can make any use of it, and the cost of continuing to develop/maintain/secure macOS and iOS is quite literally baked into the cake of the purchase price you pay for the hardware. If you think you're not paying for macOS and iOS, you're wrong -- it's just that there's no measurable, separate cost, so it's easy to miss or even trick oneself into believing it doesn't exist.

Let's flesh out your example a bit further. You say you purchased a Mac that came preinstalled with OS X Mountain Lion (10.8). That would mean your purchase date would have been between July 25, 2012 when Mountain Lion was first released, and October 22, 2013 when Mavericks (10.9) was released. In other words, your Mac is between five and six years old. I'm glad it's still working for you; Macs tend to be great like that. But a five or six-year old computer (even a Mac) is pretty old, and the day will come in the not-too-distant future when you'll either start wanting a newer, faster model or you'll actually need to get one in order to be able to run necessary modern versions of things. And when you do, part of the price of that new computer that you pay to Apple will go to all of the folks on the software side who kept you in "free" macOS upgrades during the entire lifetime of your previous Mac. That's just the way it works; neither Apple nor any other company runs their software business as a loss-leader without compensation of any kind.

Moving now to our case. With us (AgileBits), the software - 1Password - is all we do. Since we don't make smartphones or computers or tablets to sell you, we can't conceal the cost of our software by folding it into the purchase price of a device you buy from us. More importantly, we also refuse to take venture capital funding from "angel investors" to whom we'd then be accountable, and whose interests for 1Password might be very different from our own or that of our users. We prefer to make the entire cost of developing and supporting 1Password visible to the potential user, instead of trying to conceal the true cost behind ad sales or marketing your "user profile" data to "selected partners, so you can each fairly decide for yourselves whether 1Password is "worth it" to you. With 1Password, you get the peace of mind that comes from knowing that the entire revenue stream of the company developing the app in which you store your most important, sensitive data comes from the direct sale of 1Password to users (either in license or subscription form), you are our customer, and not our product.

@Jonathanm1 - yep, adding an SSD can really increase the speed of things on an older Mac using either a "Fusion" drive or an old spinny-platter hard drive. But even that boost only gets one so far; it can't increase the bus speed, and eventually the rest of the system that can't be upgraded as easily as swapping out some RAM or the hard drive becomes old enough that Apple will drop support for it the next time macOS is upgraded. That can be anywhere from six to ten years, depending upon multiple factors, including Apple's discretion. So definitely enjoy your new Ferrari, but don't forget that it's not an indefinite upgrade. :)
