Has your Mac been acting a bit funny of late? Are you seeing the occasional system error thrown at you, with some random error code like error code 50 or something like that? If you start to see such errors often, it is probable that your Mac’s OS is corrupted or not set up properly.
In some cases, this is an easy fix with just a download of an update. If you didn’t know, any operating system from Apple goes through multiple iterations in the form of updates. Even old operating systems like Mountain Lion still continue to get updates from Apple. This means that very intelligent coders at Apple are still sitting and working on Apple old OS X versions, trying to give you a better, more stable operating performance.
So, even if you don’t use the latest operating systems like Sierra, El Capitan, Mavericks or Yosemite, please know that you might be getting updates nevertheless. It is up to you to download and update these updates and see if such updates will fix your Mac OS or OS X corruption problems.
Another way to check OS corruption is to run a test like Etresoft. Etresoft is a freely available software for Mac users that will tell them what is wrong with their Mac. It will list common OS errors and also give you other vital information that pertain to spamware and adware that are other major issues that can be tremendously slowing down your Mac. In fact, when you are asking yourself why is my mac so slow all of a sudden, it could be because you have inadvertently installed some spam or adware that is causing havoc to your Mac’s OS, causing it to become corrupted even if it wasn’t corrupted in the first place.
