Removing Caches and other Temporary files can save space on your hard drive and in some cases even stop apps behaving erratically or sluggish. The following steps will show you how to safely remove Cache, Log and Temporary files from your system. Removing these files triggers the applications to build a new file when it’s. Apr 19, 2017 This video demonstrates how to access the caches folder on the Mac so that you can clear and clean caches and temporary files in Mac OS. MacOS Sierra and newer: - Hold down the SHIFT key to reveal. Feb 21, 2017 The concept is how can Unity make it simpler to work out what files can be trimmed, can I just delete the Library folder or only some sub-folders. With a Temp post/prefix or Generated / Core branches then it becomes much clearer what files can be removed safely.
You’ve no doubt heard the term cache and temp files, at least as it relates to your Mac. There are numerous times when removing a cache or temp file may be part of a troubleshooting tip to return an app or the system to a more robust condition. It’s also common to hear about removing these files to free up space on a Mac’s startup drive.
But before we head down the road to clearing out cache and temp files, let’s take a moment to find out what functions they serve, and whether it’s really a good idea to remove them willy-nilly.
(Third-party utilities, such as TinkerTool System, can help you remove troublesome cache files.)
What Are Cache Files and Temp Files?
Cache and temp files serve a similar function; they provide a place to temporarily store data in files on your Mac.
Cache and temp files serve a similar function; they provide a place to temporarily store data in files on your Mac.
Cache files are accessed and updated frequently, and they can remain after the app or system function that created them has closed or exited. They can also remain through shutdown or restart cycles.
Temp files are created by an app or system process to temporarily store data that is later used by the process that created the file. Unlike cache files, temp files are usually removed by the process that created them, usually when the process exits, or during a shutdown or restart cycle.
Examples of cache files include browser caches that save the information from a webpage. When you return to the same page, the browser can load the page data from the cache file, provided the page data hasn’t changed. This saves you the time it would take to access the web server and download the entire page again. Pitch perfect ost download torrent.

Another type of cache you use everyday on your Mac is the DNS cache. Like the browser cache, the DNS cache can let your Mac grab the IP address of a website it has visited recently without having to perform a DNS lookup, which can take a great deal of time.
Other caches are used by the system to store frequently used icons, images, and just about any type of information that is used over and over, where storing the data is faster than recreating the information every time.
(My system temp files are located in a folder named T, at the end of a cumbersome pathname.)
Temp files, on the other hand, are transitory; they tend to be removed once the app or process that created them is terminated. An example of a temp file is an application that has many levels of undo. In the loosest of terms, the undo temp file holds the state of the app at each point a command was issued, letting you go back in time (undo) to previous states. When you quit the app, the undo temp file is deleted since it’s no longer needed.
Temp files can also hold static items, such as an image, or data that will be used frequently by an app but doesn’t need to be saved beyond the current app cycle.
Where Are Cache Files and Temp Files Located?
The Mac has two primary types of cache files, System and User, which are located in three primary locations. Unhide library on mac. The system caches are located at /Library/Cache as well as /System/Cache. The user caches are located at ~/Library/Cache. The tilde (~) in the last cache location is a shortcut for your home folder. So, if your home folder was named tnelson, as mine is, the full path would be /Users/tnelson/Library/Cache. As you can see, it’s easier to just use the shortcut than to type full pathnames.

Temp files, especially those used by third-party apps, can be located just about anywhere, making some app temp files difficult to track down. However, apps that follow good coding practices will make use of a few standard locations. Unfortunately, many of these standard locations are hidden from the Finder, blocking you from direct access. You can use the following Terminal tip to open a Finder window on two of the most used temp locations:
- Launch Terminal, located at /Applications/Utilities.
- Enter the following at the Terminal prompt: open $TMPDIR
- Hit Enter or Return on your keyboard.
- A Finder window will open on the current system temporary directory.
Note: The Finder window will have a different name for this directory. The $TMPDIR is a variable that holds the current temp directory pathname.

(Terminal’s “open” command can be used to view the directories being used by the system for temporary storage.)
The second common temp location can also be found using Terminal. Enter the following at the Terminal prompt:
- Open /tmp
- Hit Enter or Return on your keyboard.
- A Finder window will open on the tmp directory.
Should You Remove Cache and Temp Files?
Generally speaking, the Mac’s operating system is pretty good at managing both cache and temp files. The Mac OS includes maintenance routines that are run at specific times to clear out unneeded cache and temp files. In addition, most temp files are cleared out automatically by the app or process that created them. The Mac OS will also remove many of the temp files whenever you shut down or restart your Mac.

Even though the Mac OS tends to take care of cache and temp files, there are times when manual intervention may be appropriate. As mentioned earlier, deleting cache files is a common troubleshooting tip. In these cases, a specific cache file may have become corrupt, and as a result, contains bad or meaningless information that is causing a related app to lose its mind. Cache files can also become excessively large, leading to long load times for the app that makes use of the file, or unusually long times for executing a specific function.
(Using the Managed Storage feature of OS X Sierra, I found over 70 GB of cache files used by an app I haven’t used in quite a while.)
The other common reason to remove cache and temp files is to increase the amount of free space on a storage volume. In researching this article, I discovered that a number of cache files used by the Steam gaming platform had grown to over 70 GB on my Mac. This was a surprise, since I haven’t used Steam in over a year, and really had no use for those cache files. The Steam cache files got the heave-ho.
But before you dump your cache and temp files, remember that generally speaking, cache and temp files are designed to improve the performance of an app or service. So, unless you’re having issues, including needing more free space, or an app that’s behaving badly, it’s probably better to leave the cache and temp files alone and let your Mac manage them.
Removing Cache and Temp Files
Warning: Before you remove any cache or temp file, make sure you have a current backup of your Mac.
One method for removing these files is to simply navigate to their location and send the various cache and temp files to the trash. You can use the Finder and the tips mentioned above to locate the files. Do not, however, delete the various cache folders; just the actual cache files within the folders.
An even easier way to access and clear out the files is to use a third-party app designed to assist in managing cache and temp files.
(Cocktail provides an easy-to-use interface for deleting cache files.)
A number of these apps come to mind; most are available as demos to try out:
- Cocktail: This is a general-purpose utility for repairing and optimizing your Mac. It also gives you access to many of the Mac’s hidden settings, including the ability to run the various cache maintenance scripts.
- Onyx: Provides access to hidden Mac features, system maintenance, and the ability to customize the system and some apps.
- TinkerTool System 5: Provides access to many hidden preferences and settings of the operating system. Includes the ability to restore caches if you discover that removing a cache didn’t fix an issue.
Remember that cache and temp files are there to help performance. For the most part, I don’t recommend wholesale removal of these files as any type of “maintenance” practice. Instead, selectively removing a cache or temp file as part of a troubleshooting process can be a useful task.
So, your Mac is running out of storage. Download mac os 10.7 1. You try to figure out what’s taking up your disk space by clicking the Apple logo on the top-left of the screen, selecting About This Mac, and hitting the Storage tab.
To your surprise, you see a yellow bar representing “System” that seems to occupy way more space than you think it should. In the example above, it only shows 207 GB, but take a look at this Apple discussion — some Mac users report that System Storage takes an astonishing 250 GB.
Worse yet, you have no idea what’s included in “System” storage, because clicking the “Manage” button brings you to this System Information window… and the “System” row is greyed out.
Why does my Mac system require so much space?
What does it contain?
Is it safe to remove some of those system files?
How do I regain more storage space?
Questions like these may easily get to your head. Although my Mac now has a good amount of disk space available, I’m always wary of files that are taking up more space than they should.
I have no idea why “System” is greyed out while “Documents,” “System Junk,” “Trash,” etc. allow you to review the files based on size and type. My hunch is that Apple does this on purpose to prevent users from deleting system files that could lead to serious issues.
What Files Are Included in System Storage on Mac?
During my research, I found many people report that Apple counts iTunes backup files and app caches (e.g. Adobe video cache files) in the System category.
Since it’s greyed out and we are unable to click on that category for deeper analysis, we’ll have to use a third-party app to assist.
CleanMyMac X is perfect for this kind of analysis. Since I tested the app in our best Mac cleaner review, it immediately came to my head when I saw “System” was greyed out in Storage. Note that CleanMyMac isn’t freeware, but the new “Space Lens” feature is free to use and it allows you to scan your Macintosh HD, and then show you an in-depth overview of what’s taking up disk space on your Mac.
Step 1:Download CleanMyMac and install the app on your Mac. Open it, under “Space Lens” module, first click the yellow “Grant Access” button to allow the app to access your Mac files and then select “Scan” to get started.
Step 2: Soon it’ll show you a folder/file tree and you can hover your cursor over each block (i.e. a folder). Cant see library folder under my user folder mac. There you can find more details. In this case, I clicked “System” folder to continue.
Step 3: The file breakdown below indicates that some Library and iOS Support files are the culprits.
The interesting part is that the System file size shown in CleanMyMac is much smaller than the size shown in System Information. This puzzles me and makes me believe that Apple definitely has counted some other files (not real system files) in the System category.
Mac Temp File Cleanup
What are they? I have no clue, honestly. But as reported by other Mac users who experienced the same issue, they said Apple also considers app caches and iTunes backup files as System files.
Out of curiosity, I ran CleanMyMac again for a quick scan. That app found 13.92 GB in iTunes Junk. Further review revealed that the junk files are old iOS device backups, software updates, broken downloads, etc.
But even after adding this amount to the original system files returned by CleanMyMac X, the total size is still a bit less than what’s returned in System Information.
If cleaning the System Storage is still not enough to bring your Mac available disk space to a normal level (i.e. 20% or more), see below.
What Else Can I Do to Reclaim More Disk Space?
Remove Temp Files On Mac
There are tons of ways out there. Here are a few of my favorites that should help you get back a decent amount of space quickly.
1. Sort all files by size and delete old large files.
Open Finder, go to Recents and look at the Size column. Click on it to sort all recent files by file size (from large to small). You’ll have a clear overview of what items are eating up a large amount of space, e.g. From 1 GB to 10 GB, and from 100 MB to 1 GB.

On my MacBook Pro, I found a few large videos that could be transferred to an external drive.
Note: If the Size column doesn’t show up, click on the Settings icon and select Arrange By > Size.
2. Remove duplicate files.
Don’t forget those duplicates and similar files! They can stack up without you being aware of it. Finding them is sometimes time-consuming. That’s what Gemini 2 is designed for. Simply select a few frequently used folders (e.g. Documents, Downloads, etc.) in the main zone of Gemini. Asa asha album download torrent.
It then scans them and returns all the duplicate files that might be worth removing. Of course, it’s always a good practice to review them before doing so. You can also read more from our detailed Gemini review here.
