Updating the mac system

Now connect your laptop to a wired network – don’t use Wi-Fi.
Want to check for software updates in Mac OS Mojave?
Perhaps you’re wondering where system software updates went in Mac OS Mojave?
While this change may be unusual to some Mac users, other longtime Mac users will recall that Mac OS X used to deliver system software updates through a “Software Update” control panel too, but that went out of favor for a while as updates then arrived through the Mac App Store “Updates” tab.
The App Store continues to be where you download updates to Mac App Store apps however, so as part of a general update and maintenance routine you’ll want to be sure to check for system software updates as well as the Updates tab of the Mac App Store still.
This is a serious problem, and when it occurs you’re probably looking for a solution as soon as possible.
Here are several potential causes behind this malfunction and the fixes that can help you get back to normal.
Sometimes this Touch Bar update is especially sensitive to internet connections or doesn’t respond well to other factors in the update process.The best way to deal with this is to reinstall Mac OS entirely. You don’t have to erase your disk to do this, which means you should be able to keep almost all your saved data (which is unlikely to have caused this particular problem).When turning your Mac on, simple hold down the “Command” and “R” keys to get started. From here, choose “Reinstall Mac OS.” When prompted, choose “Continue” and follow the instructions to complete the reinstallation.This problem is often traced back to Mac Books that have the Touch Bar.The Touch Bar acts much like a built-in accessory, and has specific firmware dedicated to its operation.
