Cannot Upgrade to Sonoma
Hello
I am currently running macOS Monterey 12.7. I had to stay in this OS until I got all of my files from my Drobo to my ThunderBay drive, since Drobo was no longer compatible.
Now I am attempting to upgrade to macOS Sonoma, but getting the error:
Update not found
The requested version of macOS is not available. Please check if your Mac is compatible with this software.
I then attempted to update to macOS Ventura and got the same error.
I have the Late 2013 Mac Pro with 3.5 GHz 6-Core Intel Xeon E5, 32 GB 1866 MHz DDR3, AMD FirePro D700 6 GB. 234 GB of hard drive space available.
It shows in the app store that these tow upgrades are compatible. How can I upgrade?
Thank you
Cooch
Mac Pro, macOS 12.7
