Si you recently upgraded your RAM of your Mac or you are simply suffering from freezes or sudden reboots, it would not hurt to find out if the fault is in the new installed memory or simply know that the problem lies elsewhere. For this, nothing better than a program that performs a test of it, making it work to see if it fails at any time and thus confirm it.
Actually this program is not an application as such that we can launch from our applications folder but it has been ported from UNIX and we will have to use the terminal in order to start the test.
The package installs a few files in the path usr / bin and once we have the terminal open we can launch it using the command:
memtest all NUM
Here NUM refers to the number of times we want the test to be performed, Since the more passes it makes, the more likely it is that if your RAM is in bad condition the failure will appear, in this way we will replace NUM with a numerical value, normally it would be 2 to perform two passes. If we leave it without value, it will make infinite passes until we stop the action with Ctrl + C
Personally, I have used this program because I expanded the RAM of the iMac when I bought it, however in the meantime I have been suffering some strange bugs in Safari and that after some preliminary checks at the end to rule out more serious problems I have passed the test with negative results, so I already know for sure that it is not the fault of the RAM. In short, it seems like a success to install it because due to its size of only a few kilobytes and the simplicity of entering the terminal and launching it with a command, it is highly recommended in cases of doubt and it never hurts to have a tool for testing by hand.
