Surprising Facts About Your Mac Computer

After a year, using my MacBook Air, got slower and slower, and the browser even froze. I checked out "All my files" and found out that most of my images where double, triple and some were even seven times stored! For hours and hours, I deleted images and files. Learning about your Mac computer, and using these tips from CleanMyMac will save you time and space on your Apple device - that I had wasted. Learn here about your Mac:
.
Your Mac computer has huge “ghost” folders
System files on your Mac’s hard drive take up easily 60 gigabytes on average, according to MacPaw engineers. These files are mostly useless — logs, caches, and application leftovers (like iTunes junk). And what’s even sadder, you can’t access them even if you have admin rights. Due to system errors OS X may sometimes lose permission and needs a cleaning.
.
Mac stores just everything
Every picture you viewed on Facebook or elsewhere on the web may stay on your Mac forever. Until you clean it manually. For instance, Twitter alone stores an image cache of many gigabytes within the depths of your Mac.  Even the most innocent websites store their cache in virtual memory, which means your Mac eventually gets slower.  And, the longer your apps work in the background, the more cache it generates.
Browsers are meant to collect cache data to give you a quicker access to the websites you’ve already visited. But very often this turns into real mess, resulting in browser freezing, persistent notifications, and pop-ups. Your Mac remembers everything you clicked, watched or even typed to your friends. Think of the chat history in your messengers. Some of them store data remotely on their cloud servers. To sum it up, a regular browser cleaning is a practice worth thinking about.
.
Some Apps Drain the Battery
Junk applications or a stealthy malware running in the background can drain your Mac’s battery faster. Surprised? Yes, Macs do get infected with junkware and there’s no easy way to get rid of it. Ironically, this may happen after you’ve downloaded an antivirus software (some free antiviruses can be a nightmare to delete).
.

Battery Issues:
Every application which heavily exchanges data with an online server is a potential battery-drainer. The same goes for numerous opened tabs in browser.  But if your battery dies too fast you shouldn't immediately rush to a store to buy a new one, there's still something you can do. First, go to Activity Monitor app and check which programs are using more power. Quit and uninstall all the unused vampire applications.
.

Your Mac Loves Copies.
iTunes and Photos being generally superb tools, but have a strange habit of creating excess copies of files whenever they can. For example, if you keep your photos in the iCloud library, all your images are stored in the cloud.  But when you view these images on your Mac, Photos creates cached copies locally.  So even if you keep all your photos in iCloud, their local copies are still wasting space on your Mac.
iTunes has long-established reputation of a tricky application because of the Library issues.  After many years of use and back-uping, it may be out of order.  The music folders you deleted years ago may still be indexed and contain useless artwork and playlist files.  And, if your music collection is big enough, these junk files may result in gigabytes taken from your memory.
.

Your Mac Stores Too Many Extra Languages.
Your Mac can speak nearly all Earth’s languages, but all those hundreds of localizations are taking a whole lot of space. Why keep these 150 language versions forever in your system?
