Mac Os can't find updates.

[Rikchell]

Im using catalina 10.15.6, there is an update for 10.15.7 but mac os says that the system its already uptodate. If i donwload and try to install manually i get unsuported system error. If i try to make a new pen drive and download from the patcher the new version i can't get the installation to work. I don't now how to update to 10.15.7.

The new pen drive is the way to go. It should work. I was able to upgrade to 10.15.7 using that method (with patch to handle 64 GB on my MacPro3,1 but MacPro4,1 and MacPro5,1 don't have that problem).

Use Terminal to update, like this:

• Open Terminal and enter: sudo softwareupdate -i -a
• Insert your password

AND/OR

• Create MacOS Update.command file with TextEdit in Applications folder with text: #! /bin/bash sudo softwareupdate -i -a osascript -e 'tell application "Terminal" to quit' & exit 0
• Run in Terminal: chmod u+x /Applications/MacOS\ Update.command
• Right click ”MacOS Update”, click ”Hide extension”. Copy a nice icon from a .png file or from another app file (file info) to the upper left corner of the file info window.
• Run the app regularly and enter your password when requested.
• To run it at startup, add MacOS Update in System Preferences > Users & Groups > Login Items

DISABLE AUTOUPDATE

• Run in Terminal: sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate AutomaticDownload -boolean FALSE

Maybe even better solution without Terminal windows or password prompts (no need for sudo, it seems):

• Launch Automator
• Select Application
• Select Utilities > Double click ”Run Shell Script”
• Select shell: ”/bin/bash”
• Add this to the text field: #! /bin/bash sleep 30s osascript -e "do shell script \"softwareupdate -i -a\""
• Save to Apps with filetype App. Give it an icon.
• Add to System Preferences > Users & Groups > Login Items
• Run at will.

Installed a fresh Catalina 10.15.5 with last Catalina patcher but cannot find any update, the result of command sudo softwareupdate -i -a is 'No updates are available'
