Thanks for the tip, I do normally do that as a first instinct when installing things. However, Megasync wasn't on the official cachyos repo for me like many things I end up looking for :( So I had to check the vendors website to see if it was even available on Linux at all.
Perhaps I should have just checked the AUR repository or installed it via a different method instead of doing all that beforehand. I admit it's my fault for not looking up what wget even was at first lol
