Plus useful information for Mac users...
"An option for MacOS 10.13 and 10.14 users
————————————————————--
Affects MacOS users who are stuck with 10.13 and 10.14.
We cannot support MacOS 10.13 or 10.14 as we do not have anyone willing to do it, or who has the knowledge to get it working. For this reason, the later releases of ElectrumSV do not work with those versions of MacOS. Users however who are stuck with 10.13 or 10.14 have reported that ElectrumSV 1.3.4 works fine. For this reason we are making it available again on our web site."
