Library Chache Mac
You can delete app cache on Mac in the same way as user cache, by going to /Library/Caches and removing the insides of the folders with the app name. Proceed with caution! Not all app cache can be safely cleared. Some app developers keep important user info on cache folders. Backing up a folder before you delete is always a good idea. Delete caches and save disk space Authored by: TigerKR on May 01, '06 09:34:10PM Just for reference, I will reiterate what has already been said about the long-term importance (or lack there of) of files in the /Library/Caches directory. May 30, 2019 What is the Library folder on Mac? The Library folder In macOS is the system folder which keeps important support files, such as user account settings, preference files, containers, application scripts, caches, cookies, fonts and other service files. All these files help your Mac and applications to function as they should and work fast.

For an Intel equivalent of the disk space usage, try Disk Inventory, also free.
Also, to skip the typing everytime & for a graphical interface, these options are available in both maintenance tools of Onyx and iTweax.
The heavier-duty Onyx actually doesn't indicate the amount used by the Cache, which the light-weight iTweax does.
I recently recovered 5 gigs of hard drive space using Tiger Cache Cleaner. My iBook also starts up and runs noticeably faster now.
$ du -k ~/Library/Caches/ sort -n
Great for spotting where that space is going
(you may need to sudo it)
$ sudo -k ~/Library/Caches/ sort -n > du_cache.txt
to get a text file
Doesn't work..

I meant to add, that I want to add something like this to my ~/.bashrc:---
Father of Jeremy Logan
just use a . (ie. period) in place of pwd.. and no quotes. FYI: in unix the . stands for the current directory and a . stands for the parent directory.
It's easier than that!
du -k sort -n
du defaults to the present directory
(Comparable to TreeSize on Win-Systems)

I'm not sure if this hint has been posted before but if you get info on each application file there are installed language options. I went through all of my apps and deleted all of them except english. Most times this will halve the size of the app. Apple is notorious for installing 12 different languages for each app. I believe there is an apple script that does this automatically too.
Just be careful about deleting some application localizations. Some applications may have dependencies to those localizations. Some time ago, I remember a problem when someone tried to delete localizations, and they ended up having to reinstall that application.
Yep, certain apps can mysteriously misbehave after you've deleted their language localization files. And Apple software updates can reinstall ones you've deleted so it's not necessarily a one-time removal routine.
I don't see any reason to risk removing those files unless reclaiming disk space is a necessity and there are no safer alternatives.
I can recommend Monolingual (monolingual.sourceforge.net), a neat little software that does just that - removes language resources you don't want/need. I've been using it for a couple of years now without problems (making sure never to remove any of the English varieties (my system language).

Just for reference, I will reiterate what has already been said about the long-term importance (or lack there of) of files in the ~/Library/Caches directory.
Recently I discovered a bug in an application (the producer of said application was 'some kind of fruit company' who shall remain nameless), and the top level tech that I was working with confirmed that its no big deal to delete the contents of the ~/Library/Caches directory.
I'm not advocating that you empty the directory and then lock the folder so that it can never be populated, nor am I advocating that you empty the directory at all. I'm simply stating that you can empty the directory and its not a big deal.
If your Caches folder is out of control, then you should think about some sort of cleaning.
For comparison purposes, here are the current sizes for my (Mac OS X created) Caches folders:
/Library/Caches
24.7 MB
/System/Library/Caches
11.6 MB
/private/var/root/Library/Caches
16 KB
~/Library/Caches
80.2 MB
The oldest directory within the ~/Library/Caches directory was modified Apr 4 2006.
I'd be cautious deleting ~/Library/Caches/Metadata because it contains Spotlight proxy files used by iCal, Safari, and other apps. Something will eventually trigger those files to be regenerated but before that happens Spotlight searching may be temporarily crippled. I discovered that awhile ago with Safari bookmarks and eventually deleted and restored the Bookmarks.plist file to force proxy files to be rebuilt after other methods had failed to do it.
First, a true confession: Until very recently (i.e. today) I didn't know about the need to periodically delete the cache and as a result, mine was gigantic.
I deleted the cache by dragging it into the trash and then emptying the trash. Then I told the computer to restart. I understand it takes awhile to rebuild the cache, but I'm not sure what 'awhile' means. It's been almost 2 hours now and I'm wondering if that's normal for the (gulp) years worth of stuff that was stored in my cache. How many hours should I let this continue before taking some other action?
Thanks for your help.
Have you ever wondered why your Mac is running slow? Does it freeze when performing even just the simplest of tasks? Does it take a while to launch and switch programs? Everybody has gone through this excruciating pain at least once.
Even though the Mac is known to be a high-performance machine, it disappoints us sometimes as it slows down over time. There are numerous reasons why this happens. The main reason is a full hard disk. The more available space your Mac’s hard disk has, the more efficient your Mac will operate.
You may ask why your hard disk runs low on space. One of the culprits could be your hard disk cache has become loaded with unnecessary files.
What is Cache?
Cache files are data saved by browsers, systems and applications on your hard disk to guarantee a smooth user experience. It is mostly used to speed up processes.
For instance, Safari will load images on a webpage and downloaded them to the cache so that the next time you visit the website, you don’t need to download them again because they can be retrieved from the cache. This reduces the wait time to load webpages.
As time goes by, the number of cache files increase considerably. Even though they are temporary and can be deleted, most people don’t bother to do so. In turn, these cache files start to take up storage space resulting in lowered system performance.
Cache files include system cache, app cache, browser cache, library cache and more.
Although other operating systems store cache in different file locations, the Mac OS stores cache files in the cache folder.
How Does Cache Affect Your Mac?
Although the primary purpose of cache is to provide a smoother user experience, the constant build up of data leads to storage space issues on a Mac.
Cache files are small in size, however going a long period of time without cleaning the hard disk means that these cache files can increase to gigabytes in size, resulting in a system with a minimum of disk space to operate. It affects the smooth performance in which Mac computers are known for.
To avoid this from happening, it is recommended to clear your cache regularly.
How to Clear the Cache on your Mac Manually?
Mac systems are harder to clean compared to other operating systems as the destination is located within other folders and files. With the lack of knowledge on how to clean a Mac, the most inevitable question asked is: How to clear the cache on Mac?
Many people prefer opting for the longer route and cleaning the cache themselves. There are several types of cache files and each file is stored in different locations and cleared differently.
Here’s how different types of cache files can be cleared manually on your Mac:
User Cache:
User cache takes up the most space on your hard disk which is normally located in the User Cache folder “~/Library/Caches.”
Although a good cleaner locates and clears cache files well, manual deletion requires more work.
Reminder: User cache also includes sensitive data. Some users may encounter errors opening the files and system applications after clearing it entirely. It is recommended to perform a backup first.
To create a backup:
• Select “Go to Folder” in the Go menu of a File folder
• Type “~/Library/Caches” and press Enter
• Select all using ‘Ctrl+A’ and copy all folders and files
• Go back to Library and create a new folder ‘User Cache’
• Copy all data to the new folder
To remove user cache:
• Select “Go to Folder” in the Go menu of a File folder
• Type “~/Library/Caches” and hit Enter
• Go into each of the folders and delete every file
We recommend that you remove the files inside the folder, not the folder itself
After you have deleted all cache from the original location, you may delete the created backup as well.
System Cache and App Cache:
System cache is composed of files stored by system applications that run in the background of a Mac.
App cache consists of media files downloaded by the applications in order to speed it up, as well as system thumbnails, temporary downloads, and so on. Although useful, app cache takes up significant space over time and needs to be cleared.
To remove system and app cache:
• Type “~/Library/Caches” and remove the data inside of the folders with the app name.
One important thing is that not all app cache is safe to be cleaned. Applications are designed to keep essential data in some of the cache folders. To avoid mishaps, backing up cache data before cleaning is always a safe option.
In order to make sure no harm is done, you may delete the backup after some time.
DNS Cache:
The DNS cache is a type of system cache. These are old cache entries that translate internet domain names (e.g., drcleaner.com) into IP addresses on your Mac. Regularly clearing DNS cache ensures an uninterrupted connection to websites.
To clean the DNS cache:
For older Mac OS versions (before OS X 10.10.0):
• Open Terminal via Spotlight.
• Type into Terminal:
“sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder; say cache flushed”
• Enter admin password to complete.
For latest MAC OS versions (Mac OS X 10.10.0 and above):
• Open Terminal via Spotlight.
•Type into Terminal:
“sudo discoveryutil mdnsflushcache; sudo discoveryutil udnsflushcaches; say flushed”
• Enter your admin password to execute.
Browser Cache:
Internet browsing is the most commonly known activity on a device as well as a major source of income for many. While we browse from site to site, all activities result in a growing cache.
Browser cache consists of website data such as images, scripts, and so on, in order to speed up your browsing experience. It allows you to visit the same website faster with the use of the stored cache on the computer.
Aside from freeing space on your hard disk, clearing the browser cache accomplishes multiple purposes. It can secure privacy by deleting the browsing history. It can also potentially help to get rid of known errors such as error 404, 502, and so on, often caused by a corrupted cache.
Each browser stores cache differently, meaning, the process of clearing cache differs across browsers. As for the most commonly used browsers, Chrome’s cache location is in ‘Settings’, Safari stores it in ‘Privacy’, while Firefox’s location is under the History tab.
To Clear the Browser Cache:
For Chrome:
• Click the options icon at the top right corner of the Google Chrome browser
• Choose Settings
• Choose “More Tools,” in the left menu
• Click “Clear browsing data.” [Shortcut: ⇧⌘⌫]
• Select only Cached images and files and Browsing history
• Select ‘the beginning of time’
• Click “Clear browsing data” button
