Manage Storage


It is generally a good computer practice to alway keep at least 15% to 20% of the Total Drive Capacity’s as Empty Space.


Allowing the computer to drop below these guidelines may eventually, cause unintended consequences including what this computer is experiencing.


There is Purgeable Space and there is Empty Space.


Purgeable Space which is Controlled by the Operating System. When the Operating Systems decides the computer needs additional Empty Space, it will move a portion of the Purgeable to Empty space


AFAIK - there is no User Actions to hasten this transition from Purgeable to Empty Space


It can day or longer before this will occur

TM Backup will make Snap Shot on the Internal Drive awaiting the TM Backup Drive to be attached. 


Only then will the Snaps Shots be transferred to the External Drive and deleted the Internal Drive.

Other / System Data: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.

Hi armnleg2,


It seems like your MacBook Air is running low on storage space, which is causing issues with your Mail application. The System Data occupying 206.98 GB out of the 245.11 GB available is quite a large amount, and it could be contributing to the problem.


To free up space on your home folder, you can start by deleting unnecessary files and applications that you no longer use. You can also transfer files to an external hard drive or cloud storage to save space on your MacBook Air.

Another way to free up space is to clear out the cache and temporary files. These files can accumulate over time and take up valuable storage space. You can use cleaning software like CleanMyMac or Onyx to help you clear out these files.


If you're still having trouble with your Mail application, you may want to consider rebuilding your mailbox or resetting Mail's preferences. This can help to fix any underlying issues with the application and ensure that it's running smoothly.


Overall, it's important to regularly monitor your MacBook Air's storage space and take steps to free up space when necessary. By doing so, you can avoid running into issues with your applications and ensure that your MacBook Air is running at its best.

Hi armnleg2,

Following up on our previous message, monitoring your MacBook Air's storage space is essential to avoid running into issues with your applications. Here are some recommended ways to monitor your storage space and keep your MacBook Air running smoothly:

  1. Use the built-in Storage Management tool: MacBook Air comes with a built-in Storage Management tool that can help you identify what's taking up space on your device. To access it, click on the Apple menu > About This Mac > Storage > Manage.
  2. Set up automatic backups: Automatic backups can take up a lot of storage space on your MacBook Air. By setting up a backup schedule, you can control how often backups are made and how much space they use.
  3. Clean up old files regularly: Regularly going through your files and deleting old or unnecessary ones can free up valuable storage space on your MacBook Air.
  4. Use cloud storage: Cloud storage services like iCloud, Dropbox, and Google Drive can help you store files off your MacBook Air's hard drive, freeing up space on your device.
  5. Uninstall unused applications: Uninstalling applications that you no longer use can help you free up space on your MacBook Air's hard drive.

By following these tips, you can monitor your MacBook Air's storage space and avoid running into issues with your applications. If you have any further questions or concerns, please don't hesitate to ask.
