Help on Installing Mac OS
I have difficulties to install mac OS in My 2019 iMac (5K Retina 27 inch) now. The iMac was on Sonoma 14.x (not the latest one) before. I tried to update it to Sequoia through the settings. At the beginning, it shows "can't verified the download". I googled, then tried to logout the Apple ID and login with Safe Boot. I can download through the settings now and start the installation. But it shows "An error occurred loaing the update" during the installation after 1st reboot. I couldn't go back anymore. So I tired all the followings: 1: Using recovery mode, erase the disk, then choose "Install Sequoia". Same issue above "an error occurred loading the update" 2: I create a Sonoma bootable USB on my another macbook, and try to boot from USB in my iMac to install. But no luck, same issue. 3: Swithing from wireless to wired and try 1 and 2 again, same error. 4: The only thing work now is that I choose to install for the cloest version which is Mojave. It works. But as long as I tried to update, it will fail again with the same error above. Can anyone shed some light here? Thanks!4
