How to unhide and access the var folder on your Mac?
What is a var folder?
Although there is little information online, it’s clear that the var folder was designed to improve operating security. It was designed to improve permissions (rwxr-xr-x) over previous temp and cache locations, such as the
/tmp folders. According to Apple developer information, the var folder refers to “per-user temporary files and caches.”
This means that this is a temporary or cache file that is not in the Home folder. This way, cache data — which Apple is keen to store — is not transferring data over a network. It makes cache data more secure and keeps everything in one place instead of scattered around multiple files and folders.
Var folders store an awful lot of data. Although there are some suggestions that these folders are emptied every three days, other research suggests that isn’t true. You could be at risk of a huge cache of data sitting on your hard drive, and some of that might contain personal user information. Instead of letting that sit around and take up space, some users choose to locate and delete this cache every few weeks or even days.
How to access the var folder?
One of the easiest ways to permanently uncover the var and other hidden folders is to use Terminal.
- Go to Terminal — Applications > Utilities.
- Type in the following command:
defaults write com.apple.Finder AppleShowAllFiles YES
- After this command, type
killall Finderand press Enter. This will relaunch Finder.
- Now, this should show every hidden folder, including var.
- Once you are ready to hide them again, go to Terminal and input the following commands pressing Enter after each:
defaults write com.apple.Finder AppleShowAllFiles NOand then
There's an another way to access the var folder by using the Finder.
- Open Finder.
- Press Command-Shift-G to open the dialogue box.
- Input the following search:
- Now you should have temporary access, so you should be able to drag it into the Finder favorites if you want it to stay visible.
Either way, now you should be able to gain access to the hidden var folders. With this access, you can delete any unwanted cache files that take up too much space. But always be careful when deleting anything: if you aren't sure what it does, it is probably best to leave it alone. Reboot or restart your Mac, as that should automatically clear out bloated cache files and folders.
