... I'm in the process of purchasing a new mac laptop and I don't think it will support my Quicken 2007 so I will keep using my 7 1/2 yr. old mac desktop till it conks out because I can use the Q2007.
... subscriptions you purchase get added on to existing subscriptions., if you are already on a subscription,. (If you are using Quicken 2017, a new Quicken subscription replaces that, and does not add onto the Quicken 2017 expiration date.) Quicken doesn't sell them to you until you are within 6 months of your subscription expiring. If you purchase on Amazon (or elsewhere), there is an expiration date on applying the subscription code, so you can't go out and buy a few Quicken subscription terms, when you find a good price, and stack them one after the other.
