Sounds good to me. SuperDuper! (SD!) is a very good cloning software app and I use it as well as Carbon Copy Cloner (CCC).

Also glad that OWC (excellent organisation) confirm the SSD.

Keep us posted. Any problems, ask away.

Update...returned the WD external HD and purchased a Insignia™ - 2.5" Serial ATA Hard Drive Enclosure. Model:NS-PCHD235 SKU:5820005. Down loaded super duper and ready to start the process tomorrow. In reading and researching I came across this...If you install an SSD on a Mac, it's important to make sure that the TRIM command is running on the machine.
Is this something I need to do or be concerned with ?
I opened up about this mac / system information / sata/sata express and there is no indication of Trim Support !
Would appreciate any advice or what to do.
This is what is displayed !

You won't see Trim, with a standard rotational HDD drive. Trim is only applicable to SSD drives. After you install the SSD in your Mac, go back and see if it has been enabled.

Update: New SSD has been cloned with super duper and installed in the MBP.
All I can say is WOW !!!
What a difference in my MBP, so much faster and all seems to be working just fine.
I opened up about this mac / system information / sata/sata express and checked Trim Support, as you can see below it says "No" !
Must this be enabled to "Yes", if so how is this done. Came this far and don't want to mess anything up at this point without guidance from the forum.
What is my next step ?
Also, is it necessary to download the "Samsung Magician ?

Checked for macos updates..all is updated, even dowloaded mac high sierra again for a fresh install. Trim still nor enabled. Very confusing reading you have provided for a non tech apple user. However, is this something that needs to be done or just use my mbp as I always have ?
Doing some research as well to understand the workings of macos and came across this.
Should I proceed, with the below and is it that easy as described below or am I opening up a can of worms beyond my knowledge of macos ?
Also is it to my benefit or necessary to download the "Samsung Magician software that came with the ssd ?

Here's how to turn TRIM on:
Make sure you're logged into your Mac with an account that has Administrator privileges. Next:
1. Run Terminal (you can search for it with Spotlight)
2. Type in this command: sudo trimforce enable and press enter.
3. Type in the password of the account you're using, then press enter.
4. The system will display a notice, then ask you if you are sure you wish to proceed. Type in y and then press enter.
5. The system will then indicate that it will reboot and ask you if that's OK. Type y again then press enter.

Now wait for the system to restart by itself and you're done. If you check again, you will see that TRIM is now running on the system., checked for macos updates..all is updated. very confusing reading for a non tech apple user. However, is this something that needs to be done or just use my mbp as I always have ?

Again thanks to the forum for all of your help. Your knowledge is well respected !


I may have missed something but I would definitely agree with Ian's comments and use his suggested method using Carbon Copy Cloner (CCC).

But I see that SuperDuper was used instead, which will work well in a lot of cases, but unless the latest version has changed and included the feature, it does not clone the Recovery HD partition or provide the option to do so as far as I know, or unless it has changed and included the future that Carbon Copy Cloner does include.

New to macos so bear with me. How do I get a Recovery HD partition ?
Also reinstalled High Sierra and now when checking disk utility I now have the below noted under disk utility.
Have I done something I shouldn't have ? What did I do to get the below. Can this be undone or am I okay ?
Should I also enable trim or leave well enough alone ?

You just created a Recovery HD, normally invisible, partition by doing the macOS x reinstall. At least that's what would normally happen.

You can always test by restarting and holding the option key down and see if it is an option to boot from, or just restart and hold the command + R keys down.

Well what do you know...I did something right ! Learning macos very quickly from the wonderful help of the forum.
Now, should I go for it and enable trim or leave things as they are ?
Anyone else having issues with enabling trim on 3rd party SSD's.

I've only been involved with Trim once with my old MBPro and a SSD with El Capitan, but I just used TrimEnabler.app as mentioned earlier. It still seems to be working well.

Deciding..pay for the app (Trim Enabler) or trying to enable through the terminal.
Any forum readers have any input on this subject ?
I just want a healthy long life SSD !
What to do ! What to do !

@WW4B

I'm going out on a limb here and being controversial, which I very rarely do.

You have achieved a very great deal since you first posted (34 posts ago). You now have a working OS, a new SSD, Recovery Partition and so forth.

If I were you, I'd forget about TRIM for the moment, at least. I'd get to know my OS, learn new procedures, enrich my experience with the Mac - and then, maybe - after a few months, when your confidence is high, consider TRIM.

It doesn't need to be done now. And, whilst recognising TRIM's role in SSD operations, it's not critical. For years Flash Storage Drives of all sorts, including SSDs, ran perfectly well without it.

I'm just concerned that having got this far, you may undo the good through some mishap.

I shall now wait to be shot down by my Forum colleagues. :Blushing::Mischievous:

Well, Ian, I for one would tend to agree with you here, and very good advice I would add!!!

Keep in mind that an SSD like a spinning hard drive has a limited life. I'm not convinced that TRIM extends the life of an SSD but there are others who are more knowledgeable about these sort of things who disagree with me. The one thing that I will emphasize to you is that you need to make backups often. Time Machine is free and is included with your Mac and there are also excellent backup apps such as Carbon Copy Cloner and SuperDuper. Losing data nowadays is as silly as allowing your auto to run out of fuel while driving on the interstate. ;D

Here's an article that gives a pretty good answer and reason Charlie, and in a nice simple explanation that I can understand:

The use of TRIM can improve the performance of writing data to SSDs and contribute to longer SSD life.
... ... ...
The SSD TRIM command simply marks the invalid data and tells the SSD to ignore it during the garbage collection process. The SSD then has fewer pages to move during garbage collection, which reduces the total number of program/erase cycles (P/E cycles) to the NAND flash media and prolongs the life of the SSD. NAND flash wears out due to the long-term effects of the P/E cycle, so reducing the number of erases can lengthen the endurance of the SSD.
https://searchstorage.techtarget.com/definition/TRIM


And that reminder about having a good current backup is so critical, if there's data worth or needed to be saved.

But the backup also needs to be checked and confirmed that it's working, is just as important, as we discovered with my cousin's backup last weekend that had quit backing up with CCC due to disk/data errors last July 3, 2018 according to the date stamp on her email.

It has been an eye opening experience on the workings of macos. To be able to post a problem, issue or general knowledge question on this forum is so appreciated in the responses that are received in that they are so informative without bias criticism to the poster's ability in the workings of the mac world is refreshing. It is a very pleasant experience in posting and have all who belong to the forum either debate your issue or offer assistance. You can learn just as much, if not more, by reading the forum members replies to your posted issue(s) than at times by reading provided web pages that are often beyond the scope of understanding to the general user that are sometimes included in your replies. This is especially true for beginners in the mac world. It is the personal replies that are included with web attachments that set this forum aside from others.
To the forum members, senior and otherwise and administrators, my hat off to you all. I have learned a lot. Remember it is the personal interaction that set you guys apart.
Please keep up the fabulous work. I for one thank you !
