to save time for those using mac. As mentioned by @ParadingLunatic ovf hash needs uses sha256 on newer releases. Here is the command for Mac Catalina

$ shasum -a 256 vmName.ovf

On MacOS 10.15 i had to use

tar -cvf vmName-NEW.ova --format=ustar vmName.ovf vmName-disk1.vmdk vmName.mf

to get it imported.

Thanks! The --format=ustar made the difference for me
