How to remove caches from the machine

It is recommended to delete the caches from your machines as generally these are of no use and occasionally caches become corrupted, impacting the performance and stability of your Mac. Deleting caches won't interfere any process going on your machine and should be done as there may be quite a few extraneous cache files in your ~/Library/Caches folder.. However, over time a cache speeds up your computer (assuming that you do some things repetitively), so if you aren't experiencing any problems, you may want to leave your caches alone. On the other hand, if it has been a long time since you have deleted your caches, or if your machine is running slowly, or if you are experiencing uncertain problems, it might be a good idea to flush them. While Apple doesn't recommend doing this routinely, they indicate that it is a good idea in certain situations. Some other famous sites also recommend this.There are two steps to delete cache from your machine:
1) /Library/Caches (Macintosh HD > Library > Caches)

2)~/Library/Caches. (Macintosh HD > your username > Library > Caches)

If you want to be on the safer side, just create a new folder on your desktop, and drag everything from your Caches folder into it and reboot the machine. You can trash the folder on your desktop when you confirm that all the applications are working as they should.
