Is Cleanmymac Worth It
Theres a very good reason why CleanMyMac built up an enviable reputation over the past four years and this version will only further enhance that.
Automatic Cleanup uses an intelligent algorithm to suggest files that are 100 percent safe for removal.

What Is A Startup Disk
A startup disk, as taken from Apple Support article, is a volume or partition of a drive that contains a usable operating system. Still confused? Lets break it down for you.
Your Mac hard drive consists of disks . Each disk has your Mac data on it, which consists of your operating system, applications, etc. Most Mac users have just one disk but power users may have two or more.
Lets look at an example of a Mac with only one hard disk:
- Your Mac’s hard drive is 500GB.
- It has one “disk” on it, so all 500GB of storage is on that disk.
- The disk has an operating system , and user data .
- And since you only have one disk, this is your startup disk: all 500GB.
A Mac with two disks will have the storage divided between them. The Mac drive with the OS on it is the startup disk while the other drive is just used for storage of files. Its possible to have multiple startup disks, but most Macs will only have one. And for proper disk cleanup on Mac, all drives are just as important.

- Your Mac runs unusually slow
- It heats up even when you’re not doing anything that would use lot of processing power
- Your Mac hangs randomly or apps crash
- Your Mac behaves in a way it doesn’t usually
If youre concerned, you can do a bit of investigative work using your Mac’s built-in Activity Monitor tool. Click on Spotlight to search for it. Once it’s open, you can see a list of all the programs and processes using processing power on your Mac. If there are processes that you don’t recognize using lots of resources, that’s a sign that malware may be present.
Top tip. Even if you suspect malware, it’s unwise to delete any processes until you’re sure what they are. Developers of legitimate programs don’t always name processes in a way that makes it clear what they are. Try searching on the internet for more information first.

If not, youll need to back up important files now but scan them with an antivirus tool first to make sure theyre not infected.

Android-specific malware has been on the rise in recent years, with huge ransomware and spyware infections affecting millions of users.

Norton is my favorite Android antivirus especially because it scans apps for malware before you download them from the Google Play Store.
For iOS users, there arent as many risks iOS is built with secure sandboxing, so theres no way for a malicious file or app to make changes to your device. However, iOS users still need to worry about unsafe Wi-Fi networks and phishing sites which can steal data, in addition to the very real problem of iPhone theft.
