Would suggest Drag and Drop to Trash and then empty the Trash.


Then commence a new download from the How to get old versions of macOS


As with an major Upgrade >>


Point # 11 - Do you have a Rescue Plan In-Place. This comprises having 3 Backups using 2 methods and 1 Off Site incase of Theft, Loss or Natural Disasters. A Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS


Point # 12 - For addition purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways. At least one Tested Clone and / or Time Machine Backup should be Off - Site

That is because it is Not an update.


It is an upGrade as in upgrading from Sierra to Catalina


The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.


With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install.  For Best results use Safari to commence the download as Others may not work.


Safari will open a redirect and open the Apple Store where the download can commence.


macOS Catalina 10.15 hardware requirements


macOS Mojave 10.14 hardware requirements


macOS High Sierra 10.13 hardware requirements



Make Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS


Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.


Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.


Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal  operation of the OS and may even Corrupt the OS requiring a Reinstallation

First of all, thanks for helping! As you may have read, I don't know much about this stuff haha!


So I found the macOS High Sierra-installation and macOS Mojave-installation on my computer already, but when I try to open it, it says they are both damaged.


Do you maybe know what this means and how to fix it?

I can't find update 10.15, what could be the problem?
