Renewing the subscription on a Mac is almost impossible and the instructions are counter-intuitive . If you follow the download instructions you get an .exe file which is useless. You seem to have two options available - 1. download a free trial or 2. a new purchase. I am already using CCleaner so I don’t need a free trial and, having already renewed my subscription, I do not need to buy this again. Why, when the subscription renewal payment is made, can you not simply extend the existing license without some protracted and seemingly futile and hugely complicated process?
