Unable to download Catalina update
I have cleared 44.75 GB of storage to download the latest version of Catalina 10.15.6 and it is still telling me that I do not have enough storage available? Help please. I need this update in order to update my Xcode that runs my necesary medical device. This MacBook Air is only one year old and I had no trouble updating my Catalina back in December 2019. I am at a loss!
