[MrProgrammer]

Hello! I ran a scan on my MacBook, and the scanner reported that XCAssets in the BaseSystem.dmg was a malware backdoor.

Any info on this?

Download OpenOffice only from http://openoffice.org/download.
Q03: How do I install OpenOffice on a Mac?

If you downloaded what you thought was OpenOffice from somewhere else, move it to the trash. There is no BaseSystem.dmg in Apache OpenOffice so I can't help further with your problem.

Edit: If your computer has a BaseSystem.dmg file, it came from some other software you installed. OpenOffice doesn't use or need it.

Good luck if you choose to install Big Sur. I would guess that OpenOffice has not been tested on that operating system.

Pretty sure that I did the d/l from that location. Nevertheless, I will delete that file and uninstall, and reinstall from a fresh download. Will post results.

Googling BaseSystem.dmg reveals it is an Apple operating system file and is not related to OO or LO Base.

False positives are unfortunately common.

Well, my face is red.

I assumed, because it had Base in the name, that it was related to my recent install of OO. Instead, it was part of the InstallCatalina package, which was part of a bootable USB I had prepared.

So, false alarm. Sorry to take up everyone's time.
