Apple macOS (Mac OS X)
The software and hardware prerequisites for installing on a Apple macOS computer are as follows:
• LibreOffice 6.3.x: macOS 10.10 (Yosemite) or higher
• LibreOffice 6.2.x: macOS 10.9 (Mavericks) or higher
• Intel processor
• 512 MB RAM
• Up to 800 MB available hard disk space
• 1024x768 graphic device with 256 colors (higher resolution recommended)
It is a recommended best practice to back-up your system and data before you remove or install software.
Notes:
• For certain features of the software - but not most - Java is required. Java is notably required for Base.
• Due to an issue, there are the following restrictions with Java: on macOS 10.10 and newer, JRE isn't found, JDK is required
• LibreOffice 4.3 can still run on OS X 10.6+, but please understand that this support ended when 4.3 was retired on May 27, 2015.
