As regards running software on a Mac, there are solutions out there to let you run Windows software on a Mac. However, given that the best ones involve a cost whereas a refurbished PC can cost well under £100, that might be a better solution - you only need a PC capable of running an internet browser so the spec is pretty irrelevant. It also allows you to separate completely work computer use from home use.

I've tried both, in fact I've had two free trails with Cleaner planner and used it for 2 months before going back to Aworka.
Both well supported, both do the same with Aworka now intergrating GoCardless and PayPal .
Aworka is £100 pa paid in Advance where Cleaner planner is £25 a month.
A lot of members here very vocally support Cleaner planner but as you say I'm not sure how many have tried both.
