One of the routines relate to my laptop is to keep everything organised. This includes folders management, removing unused files or installing/uninstalling applications, etc.
For disk usage checking purpose, I use OmniDiskSweeper. Yes, I also have Macpaw’s CleanMyMac 2, but OmniDiskSweeper will do a simple and specific task as mentioned on its site:
OmniDiskSweeper is really great at what it does: showing you the files on your drive, in descending order by size, and letting you decide what to do with them.
One of the directories using lots of storage was
~/Library/Application Support/MobileSync/Backup/. This directory stores the backup of the iOS devices. I have iPad and also iPhone. I only have 250 GB of storage configuration for my Macbook Pro, and the backup consumes tens of GB.
To remove the unnecessary backup files, open iTunes, choose Preferences, and select the Devices menu. There are some old backups that I think safe enough to be removed. So, I did that. So, I only keep the latest backup for now.
The backup solution is pretty easy and straight forward. Even I don’t regularly synchronised my files, in most cases I only backup the media files especially photo. And, I prefer to use Image Capture to save the photos/videos to the folder I wanted.
