Mac OS X is too thin, so dad no longer needs to worry about insufficient SSD capacity.

The current computer is equipped with the top 15-inch Retina MBP, 2.4G i7, 8GDDR3 memory, and Geforce gt0000m graphics card. It has extremely powerful performance and wants to ride the Spring Festival holiday, install a COD and try it out. If the result is a little installation, the system prompts that the hard disk space is insufficient. Check df and there is less than 10 Gb of available space, the BNS are equipped with a gb ssd, which is really a little small, but I usually use it to receive emails and write code. I don't have any action movies in the island country. How can I use them all? I checked the mail directory, which is only 1.3 GB, and the system cache is less than 1 GB. The Application directory, 18 GB, and github working directory are both normal. I deleted several installation packages, I made up a few G space, but I was too stretched. I scanned it again and found a/private/var/folders Directory with 96G space! Obviously too big. Put it under/private, it seems that it cannot be moved or be used. Google has found that many people are asking about the usefulness of this folder and there are various answers, there are several types

First, this folder is not large, just a few hundred megabytes. It doesn't matter if you delete or not delete it. To avoid unnecessary troubles, it is better not to delete it. But it's almost one hundred GB on my machine. You can't ignore it.

Second, you do not need to delete it. This is the system cache. After restart, the system will automatically delete it. I restarted the machine, but this folder still exists, still 96 GB

Third: This is a snapshot of the Finder and can be deleted.

Type 4: cannot be deleted. The system cannot be started after deletion.

What should I do if I haven't found an official explanation from Apple? You can only let go. Take out the mobile hard drive that was thrown on one side half a year ago, use the optical machine to make a backup, and then sudo rm-rf/private/var/folders... after a few minutes, the rm command stops returning. Restart the system. Everything is normal. Run df to check the disk usage. There is still GB available !!!

Haha, you can install COD. It is said that GTA5 may go to the MAC App Store this year ~~
