Disk Sensei

I am always on the lookout for new Mac Utility apps. Recently, I came across a very thorough and helpful Mac Utility called Disk Sensei from Cindori Software. I have played with this app a little and I like it. But, there is one feature that is totally killer in my opinion


Disk Sensei

Disk Sensei (hereinafter referred to as DS) sells for $19.99 from the Cindori website. It is a pretty versatile app. I will not going to cover every feature here, just wanted to give you an overview, but with mention of a very special feature at the end. Here is the main window:

It shows information on the drive you select in the dropdown menu under “Apple”, upper left corner:

There are lots of maintenance tools to use on the selected hard drive. Here is the “Health” Tool:

You can check the overall health of your HD or any drives attached to your Mac. You can make a graph of the stuff on your Mac using the “Visual” Tool.

To me this seems like eyecandy, but some people might appreciate it. DS has a modest cleaning feature, I think I prefer other apps for this, but it would suffice if you only could get one app:

It also has a “Benchmark” feature which I think is pretty cool. You can check out the benchmarks on your Mac:

I have not gotten to the killer feature yet, hang in there. DS also has an “Optimize” feature which may help with a few things:

All of the above is just fine and dandy. I have used DS a few times and it seems to work pretty well, it would be a nice Mac maintenance utility if you needed one. It has a few features other utility apps don’t have as well. But, the killer feature to me is the “Trim” feature.


There is a ton of debate on the tech sites whether or not using Trim on your SSD drive is needed. As far as I can tell I think it is a good idea. After all, when I check my Fusion drive on my iMac using “System Information” I see Apple is using Trim, so it must be reasonably helpful right? Here is a brief definition of Trim:

TRIM is a command that helps the operating system know exactly where the data you want to move or delete is stored. That way, the solid state drive can access only the pages holding the data. Furthermore, whenever a delete command is issued by the user or the operating system, the TRIM command immediately wipes the pages or blocks where the files are stored. This means that, the next time the operating system tries to write new data in that area, it won’t have to wait to first delete it.

If I was installing a new SSD drive in my iMac I would definitely enable the Trim feature. Having said that, up until now you had to use the Trimforce command provided by Apple in Yosemite and El Capitan to enable Trim on your Mac SSD. This disables some security features on your Mac and does stuff “under the hood” so-to-speak. It is doable, but not a great implementation. Enter the Disk Sensei Trim feature:

Now all you have to do is enable Trim using DS and then restart your Mac. No esoteric Terminal commands or under the hood stuff. Well, there is under the hood stuff, but DS does it for you. This is so cool!

I do have one caveat here. I have not tried this because the only SSD drive I own is in an external USB 3.0 enclosure, my Tech Drive as you recall. You cannot enable Trim on an external drive, although there seems to be some question of being able to do it on a Thunderbolt external SSD. So, YMMV, but as far as I can tell from the Cindori website, it works just fine.


As far as I am concerned, the Trim feature may make buying this app worth while all by itself. Either way, Disk Sensei provides enough cool, useful features to make it a contender for your Mac maintenance utility app. I think a free trial is available. Try it, you might like it.
