Thanks. A further question: I think I am using single user license, so if I install it on my two Macs, then after some months or years, I trash one of my old Mac and buy a new one, can I revoke that license and use it on my new Mac?
I had an Alfred 3 license on my old Mac, and a new Alfred 4 license on my new Mac. Can I just use my Alfred 4 license on my old Mac? How many seats does one license have?
