Bob Gaetjens Posted December 5, 2020 Posted December 5, 2020 Hello! I have recently upgraded my 2015 MacAir to Big Sur to my extreme detriment and discomfort. Everything is slow. So, I'm thinking of attempting to downgrade back to Catalina. Will I have any compatibility issues with Photo, Publisher and Designer? I assume I would have to redownload them after downgrading. Thanks! Quote
Staff Lee D Posted December 8, 2020 Staff Posted December 8, 2020 You shouldn't have any issues but I would fully remove them from your system first. Then after downgrading log back into the store and download fresh versions to install. Remember to also backup any existing files you wish to keep. Quote
