I have a 2019 27" i5 iMac with 24 GB of RAM and a 2 TB Fusion Drive, running the latest version of Ventura. I have a Time Machine backup drive and a Carbon Copy Cloner backup drive attached. Because I want something portable, I'm thinking of getting a refurbished 14" MBP with 16 GB of RAM and a 1 TB SSD and selling my iMac. I've consistently had just over 1 TB of files on my iMac. A lot of those files don't need to be on my Mac, but since I have 2 TB of iCloud storage, it hasn't mattered. To see how much I can offload from my system drive, I copied over 200 GB of files (120 GB of which is my iTunes library) to an external drive and deleted them from my iMac. The used space before I did this was 1070 GB. The used space after deleting all those files is still 1070 GB. The amount of purgeable space before and after has remained at 157 GB. Yes, I emptied the trash and rebooted my computer. Any ideas why the amount of free and available space on my system drive hasn't changed?
