Common problems of MacOS Catalina that we help you solve

The MacOS Catalina system includes a host of new features and applications, but as is often the case with updates to software, It is also normal for some unexpected failures to occur. In this article we tell you the usual problems of MacOS Catalina and, of course, we also explain how to solve these incidents.

MacOS Catalina problems in the installation

Although the process of updating to Catalina is quite simple you will find the update in the Apple Mac App Store, some users have reported problems in order to download the update. The most common error codes, at least in the first days of Catalina's download, include messages such as "The network connection was lost" or "The MacOS installation could not continue."

If you've found these error messages, keep calm and keep going (doing other things in the meantime), since it probably just means that Apple's servers are saturated. A possible culprit is that many of your fellow Mac users have been trying to upgrade at the same time and that is putting more pressure on Apple's servers. If you are trying to download the files via Wi-Fi, you can switch to an Ethernet cable, which is more stable, for best results.

If the error is related to the installation cannot continue, one of the possible culprits could be the lack of disk space. The Catalina download file has a size of 6 GB and you will need 15 to 20 GB of free space to complete the installation. To check how much free space you have on your disk, click on the Apple menu in the upper left corner of the screen, select ?About this Mac? and then go to ?Storage?. You can manage your storage here and free up space if necessary.

If these issues are not to blame for your problems with Catalina, you may want to check if the installation file has been damaged or only partially downloaded. Use the Finder menu to find the ?Install MacOS 10.15? file and remove it, restart the system and try to download the necessary files again from the Mac App Store.

You can even try to log in and out of your App Store or iCloud account, if you have more problems. Once the file has been downloaded, you will be asked to perform the update. If not, find the Catalina installation file on your Mac's drive and double-click it to begin your journey to the dark side of your Mac.

How to troubleshoot MacOS Catalina with Sidecar

If you have an iPad in addition to your Mac, one of Catalina's best features is to be able to use your tablet as a secondary display. Called Sidecar, it is ideal for multitasking and illustrators, since it adds additional space on the screen so you can do more things.

Sidecar is compatible with the iPad 6 or later tablet, iPad mini 5, iPad Air 3 and the iPad Pro line. Be sure to download the latest version of Apple iPadOS on the tablets to take advantage of Sidecar, otherwise your Mac does not I can use this function. And although Catalina works on older Mac systems, Sidecar, as a feature, requires more modern hardware. This means that you will need a 27-inch or newer iMac computer, a 2016 or newer MacBook Pro, a 2018 Mac Mini, a 2019 Mac Pro, a 2018 MacBook Air or a 2016 or newer MacBook.

You will find the Sidecar configuration in the System Preferences application in the Dock of your Mac, and you must enable Wi-Fi, Bluetooth and Handoff. Keep in mind that laptop users must connect directly to a Wi-Fi network and cannot use Sidecar while they are connected to the internet connection of their iPad.

If you have an old iPad device or an old Mac computer, don't lose all hope. Third-party applications, such as Duet Display, have provided a Sidecar-like feature long before Apple launched native support in Catalina, and more enterprising Mac users can also follow a Reddit guide to get Sidecar to work with hardware from Old Mac.
