DMG files can be helpful to keep on your Mac if you need to install programs on your computer, such as software updates. These files are disk image files, which can be mounted so that the disk image appears like a regular volume on your Mac.
This will allow you to access the contents of the disk image and install the program they contain.
However, if you don’t need to install anything and you won’t be using the files any time soon, then you can delete the DMG files to free up storage space.
What do I do with DMG files Mac?
DMG files, also known as Disk Image Files, are Mac-specific files that can be used to store data, as well as compress and encrypt files. In order to use a DMG file on your Mac, you need to mount it. This is done by simply double-clicking the DMG file, or dragging it onto the Finder window.
The DMG file will then appear as a new drive in the Finder window, or as a virtual disk in the sidebar. You can then open the virtual drive and either copy the contents inside to your computer, or you can use the files directly from the DMG file.
If you’d like to unmount the DMG file, you can drag it to the Trash, or choose Eject from the File menu.
What files should I not delete on Mac?
When it comes to deleting files on a Mac, there are certain files that you should not delete, as they can be essential to the system’s operation. Generally speaking, you should not delete any of the files located in the “System”, “Library”, or “Applications” folders.
Doing so could cause issues with how your Mac operates.
In the “System” folder, you should never delete any item with “. kext” in the name, as they are device drivers that Mac requires to run properly. You should also not delete any items with “. prefpane” or “.
mdimporter” in the name. The same goes for the “Applications” folder.
In the “Library” folder, there are several important files and folders that you should not delete. Again, never delete any items with “. kext” in the name. Do not delete anything in the “Extensions” folder.
The “Fonts” folder should also remain untouched, as Mac uses its fonts for system-level operations. Finally, do not delete anything from the “StartupItems” folder, as these files are required for certain applications to launch properly.
Finally, other items you should not delete include any system-level preference files (such as “. plists”), keychain files, and cached application data. Though these may not prevent your Mac from working in the event they are deleted, they could cause unexpected issues with certain applications or make your Mac run slower.
Additionally, be sure to not delete the home folder of any user accounts on your system.
In general, it is best to avoid deleting any system files that you do not understand. If you do need to delete a certain file or folder, it is wise to research exactly what it does first and make sure you have a backup of your Mac’s data in the event that deleting the file causes issues.
