Launching UE 4.26.1 ON OSX 10.13.6

I am a new user trying trying to launch 4.26.1 on a MacBookPro 15 running HighSierra 10.13.6, Intel Core 2.9Ghz i9, 16 gig ram, Radeon Pro 560X 4096 MB Intel UHD Graphics 630 1536 MB. I have Installed Epic Game launcher and downloaded 4.26.1 engine. When Launching I get no error messages, nothing happens after attempting to launch. I have made sure UE4Editor is “allowed incoming connections” on my firewall. Any help would be appreciated. Thanks.
