Laggy rMBP

[ggonzaga07]

I have a Macbook Pro Retina 13" which I bought around November of last year with these specs:
Haswell i5 @ 2.40 GHz
8GB RAM
256 GB SSD
After its 1 year anniversary I have noticed a decrease of performance which has been bothering me a bit, it isn't something that is making my computer worthless but it bothers me from time to time. Do you think I might have a virus?
I don't really have many programs running. For example, right now I have Safari, Messages, Powerpoint and CCleaner running. CCleaner is only running because I'm scanning through the computer to clean system logs etc.
I have VirtualBox with I think 2 Windows OS's running but I never use them. They occupy a good amount of GB in my system, like 20 GB total. I'll delete them but I think that its not it.

Performance Tips For Mac OS X​

After its 1 year anniversary I have noticed a decrease of performance which has been bothering me a bit, it isn't something that is making my computer worthless but it bothers me from time to time. Do you think I might have a virus?

No, since there are no OS X viruses in the wild. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 12 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). 3rd party antivirus apps are not necessary to keep a Mac malware-free, as long as a user practices safe computing, as described in the following link.

​

Read the What security steps should I take? section of the Mac Virus/Malware FAQ for tips on practicing safe computing.

CCleaner is only running because I'm scanning through the computer to clean system logs etc.

You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.

​

These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space. In fact, deleting some caches can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt.

​

Many of these tasks should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance. OS X does a good job of taking care of itself, without the need for 3rd party software. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.

I suspect it's Ccleaner that may be the issue. The reason I said so is that, I have installed Ccleaner in a Windows machine (yes I know it's not OS X) and since then it slowed to a crawl - deleted it and sure enough it was back to normal. Now, I have not installed it on my rMBP - wary of having the same fate as my windows after install..AS I've said, it's all a hunch

No, since there are no OS X viruses in the wild. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 12 years ago.

Whilst OS X is fairly secure, what you say about OS X not having viruses is simply not true. You can get some useful information on OS X malware here:

With that said, common sense is easily the best protection against infections on any operating system, at least when it comes to running and installing software - security vulnerabilities are another matter entirely.

Yes, it is absolutely true. To disprove that fact, name just one OS X virus that exists in the wild.

You can get a sales pitch there, since that's a company that wants you to use their product. There are more unbiased sources of malware information than an antivirus software company.
