However, it looks like there is a problem with your install and as I’m not a Mac user, I couldn’t say whether this is local to your machine or an issue with Homebrew, but fundamentally it would seem that this has not installed wget on your system and that being a dependency.
can you elaborate on the consequences of not having wget installed? i was able to download the firmware and gateware and LimeUtil --update seems to be working now. Thanks for the link.
wget is a command line application for downloading things like say a single firmware file from a website, or an entire website or multiple websites. In this particular case wget not being installed meant that “LimeUtil --update” tried to run it and failed, so it could not download the firmware. So then you needed to manually download the firmware and gateware files with a webbrowser and place them in the correct directory where LimeUtil expected to find them and then it ran as expected.
