Thanks for amazing help o_e_l_e_o I wasn't focused so nearly download the malware from the fake Joinmarket site.
Would you mind editing your previous comment to remove the link? Just in case anyone else skimming the thread clicks on it without realizing.It's safer I'll postpone using Joinmarket until I've set up Linux on old Mac I've come to own that'll be an experience learning as I ask questions.
That is certainly the safest option. Since all coinjoin wallets need to be connected to the internet constantly in order to work (you can obviously disconnect but you won't be able to perform any coinjoins while disconnected), it is safest to have a separate clean machine dedicated to coinjoins if you are going to be coinjoining frequently or large volumes.It's fair Kruw gets invited to post opinions ahead of locking the thread.
The other Wasabi thread already contains all his opinions if you care to read them. They are just the same nonsense Wasabi talking points repeated ad nauseum. 
Thanks o_e_l_e_o for amazing advice.
