I've been trying to install Garuda dr460nized in my late 2013 iMac running the latest Catalina without luck.
I create the bootable USB using either dd or balenaEtcher (tried both). I get the option to boot from the USB so it is being recognized. However, after passing the grub menu to boot from garuda I get the screen with the eagle, where it spins for about a minute or less and then stops completely (I have waited even more than 40 minutes but does not continue from there).
Thank you, sir! booting the ISO with non-free drivers was the reason. Changed to free drivers and was able to install without issues. I'm exploring the edition and looks and feels great! Everything is working, including wifi.
The only thing I noticed so far is that the screen brightness cannot be adjusted at all. I know this is a common issue so I will research about it. If you can guide me in the right direction, it'd be highly appreciated.
You've probably have a 3k, 4k or 5k screen ... or a Retina display. They're hi-def or HiDPI and you're likely at full brightness. It's one of the areas where you'll have to do a little manual maintenence on Garuda, and Linux in general.
