how to upgrade my Mac mini

I have a Mac mini running on macOS Catalina 10.15.7 I have tried to upgrade many time only to be told that the download has failed, or I don't have enough space. The latest update is Ventura which needs 11.78gB. There is over 35gB available on my Mac mini and it still won't download. Any ideas would be grateful accepted.

The macOS version you can upgrade to depends on the year your Mac was released.

Click the  (Apple) menu at the top of your screen and choose About This Mac.


Check the Compatibility of your Mac with newer versions of macOS:

➡️ macOS 11 Big Sur is compatible with the Macs listed here 

➡️ macOS 12 Monterey is compatible with the Macs listed here

➡️ macOS 13 Ventura is compatible with the Macs listed here



✅ - IF your Mac is compatible, then download the macOS upgrade installer app:

Click >  Big SurMonterey  or  Ventura.

Once downloaded, double-click the “Install macOS…” app in the Applications folder to begin the upgrade.


Please see > How to download macOS.

while the Ventura installer is only ~12 GB, it needs a lot more room to perform the upgrade. after downloading the installer, the Mac needs room for the installer to expand as well as needing room to shuffle things around during the upgrade. it is recommended to have ~ 50 GB available to attempt an upgrade.
