Installing Adobe Acrobat Reader DC is a two-step process. First you download the installation package, and then you install Acrobat Reader DC from that package file. If you have enough free storage of startup disk, you still can’t update to macOS Catalina 10.15.6, please access the System Preferences - Software Update in the Mac Safe mode. How to access the Mac Safe Mode: Start or restart your Mac, then immediately press and hold the Shift key. Release the Shift key when you see the login window. Most older Adobe apps were created using 32-bit architecture and do not work in Catalina. We have no plans to update apps that we no longer support or develop. The following table lists some common 32-bit Adobe apps that are not compatible with Catalina. (It is not a comprehensive list of all older. In my previous article, I wrote that all Macs that run macOS 10.14 Mojave will also be able to run macOS 10.15 Catalina.However, this isn’t entirely true. The Mid 2010 and Mid 2012 Mac Pro are the only two Macs that are capable of running Mojave that won’t be able run Catalina. If you see a message that the app can’t be opened because it’s from an unidentified developer or wasn’t downloaded from the Mac App Store, you can open the app by overriding the settings in Security & Privacy preferences. Sometimes a download is incomplete because the file was damaged. Try downloading it again.
