I have downloaded the latest beta and tried testing Mac OS Catalyst. It consistently fails with a signing error. I tried using an iPhone 17.2 sim but that failed to install throwing up 'Unable to boot device because it cannot be located on disk', so I reinstalled the sim but got the same error. I then tried 17.4 which simply hangs on the install.
So friends, yesterday I was progressing using beta 2, but today I have hit a show stopper. Am I the only one?
