Hi,
My storage is almost full and I would like to install Mojave on my Macbook Pro (OS X Yosemite). Do I need to delete things or is there a way to add space?
You add space by removing things from your home directory (e.g. movies, music, photo libraries, etc.) to external storage. Anything moved to the Trash that you want to delete needs to be followed by Empty Trash to free up that space. You will need at minimum, around 20 - 25GB of free space on the boot drive to fully perform the installation.
not enough space on Mac to install Mojave
