system data in the iMac growth unexpectedely to 4 GB, I´m afraid to delete any file that may be crucial how can I clean the system data?
iMac 24″, macOS 14.1
You do not want to clean the System data. Attempting to do so is guaranteed to wreak havoc with your Mac.
The best way to manage your storage space is to let macOS work the way it is supposed to. Keep your software up to date and reboot the computer maybe once a week to allow the system to clear caches and do other housekeeping.
A good rule of thumb to use to keep your Mac running smoothly is always keep available a minimum of ~10% of the total drive capacity. in other words, if your drive is 1 TB (1000 GB) keep at least 100 GB free. This way macOS has room to copy, move and otherwise do file management in the background as you use it.
If you need to free up space, start by connecting an external drive and moving your biggest files and your many least used files off of your startup drive and onto the external for storage. Photo libraries, music libraries and videos generally use the greatest amounts of drive space. There are utilities you can use to discover your largest user files so you can move them to another drive. OmniDiskSweeper and Daisy Disk are two that come to mind.
Make sure you always back up your stuff on a regular basis. If you aren't backing up your data you will lose it sooner or later.

When system data unexpectedly grows to a large size on your iMac, it's understandable to be cautious about deleting files. Here are some steps you can take to clean up system data safely:
1. Clear Cache Files:
- Cache files stored by various applications and the system can accumulate over time and take up significant space. You can use third-party cleaning tools like CleanMyMac or Disk Doctor to safely clear cache files without risking important system data.
2. Remove Unused Applications:
- Review your installed applications and remove any that you no longer use or need. Uninstalling unused applications can free up space on your iMac's storage.
3. Delete Temporary Files:
- Temporary files generated by the system and applications can also contribute to the growth of system data. Use cleaning tools or manually delete temporary files stored in directories like /private/var/tmp and /var/folders.
4. Check System Logs:
- System logs and diagnostic reports can accumulate over time and consume disk space. You can safely delete older logs and reports to free up space. However, be cautious and avoid deleting recent logs that may be needed for troubleshooting.
5. Empty Trash:
- Make sure to regularly empty the Trash on your iMac to permanently delete files and reclaim disk space.
6. Run Disk Utility:
- Use Disk Utility to verify and repair disk permissions and disk errors. Running First Aid with Disk Utility can help resolve any issues with the file system that may be contributing to the growth of system data.
7. Monitor System Activity:
- Keep an eye on system activity and resource usage using Activity Monitor. Identify any processes or applications that are consuming excessive system resources and address them accordingly.
8. Backup Important Data:
- Before performing any cleanup actions, ensure that you have a backup of important data stored on your iMac. This will provide a safety net in case anything goes wrong during the cleanup process.
By following these steps, you can safely clean up system data on your iMac and reclaim disk space without risking the deletion of crucial files or data. If you're unsure about any specific files or actions, it's always a good idea to seek assistance from Apple Support or consult with a professional technician.

Please, please do not follow any of the instructions being given by Heretostay59. Most of them are wrong, some of them, including the suggestion to use third-party "cleaning" software are downright harmful.
D.I. Johnson has given very wise advice.
+1 on not following the advice of Heretosay, some of the advice provided is rubbage and should be ignored as it can cause damage to Mac OS and make your Mac appear buggy, run slowly and do nothing that Mac OS cannot already do!
On the other hand, D.I.Johnson's advice is spot on!
You REALLY need to find a better AI to steal from. This one is for the birds, it is almost all either useless or actively harmful advice.
