Hi, totally new to LO, some searches show problems with opening in Yosemite 10.10.5, could someone confirm you just can’t open it in Yosemite 10.10.5? thanks
The link above is for libreoffice.org help. The bottom line is that you need macOS 10.10 (Yosemite) or higher, and a version later than LibreOffice 4.3. The main limitation is with Base, in that a JDK is required (as opposed to the more usual JRE).
A fix for installation under 10.10.5 is at Q64253.
