We strongly advise you to be wary of upgrading to any new MacOS. Make a full time-machine backup before proceeding.

Is your Mac older than 4 years?

If your computer is more than 4 years old and its never had it’s Hard Disk replaced, installing a new OS is usually the time that the HDD gives up the ghost and fails….. mid-install.

We hope you took a full Time-Machine backup before you tried the upgrade. If not, you are risking losing your data.

Its not the end of the world but you may not be able to find 64 bit versions of your printer driver, printer utility or even Office 2011. Something to bear in mind.
