Does anyone know whether my QuarkXpress 2015 will still work if I update my MacBook Pro to macOS Big Sur?
I'm running 11.2.0.6 now and Quark works fine. Don't want to lose its capability.
Alternatively if a Mac is upgraded to Big Sur can I revert to macOS Mojave, or even toggle between the two?
Thanks in advance
MacBook Pro 15″, macOS 10.14
According this documentation >> Software
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
MacOS BigSur
