Start with the largest files and work your way down. After you scan your drive you I could see large and common files, for me, it looks like some old Virtual Machines ( Windows and Kali Linux) and over 100GB of photos. I use Space Gremlin on OSX to find large files ( this is not a paid endorsement). I would always recommend you backup files and clear up space (and deal with the problem). I would not recommend you use Apple iCloud to extend your storage and move unused files to the cloud. I have let my free space dwindle to a mere few GBs of free space. I have blogged before about my backup plan but of late I have ignored my own advice. I have a number of guides on moving away from CPanel, Setting up VM’s on UpCloud, AWS, Vultr or Digital Ocean along with installing and managing WordPress from the command line. Apple OSX computers that only have Solid State storage need at least 1/5 free space to remain free all times to prevent the drive from wearing out ( by using free sectors repeatedly) It will happen to everyone, you will run out of space ( on your computer or device) and you will need to free some space.
