- How many times do you need to be told this? Yes, it will work.
Someone above was incorrect with respect to the screwdrivers. As you can see from the replacement guide I posted, you need: Phillips #00 and Torx T8.
Got a tip for us?

- Great to hear!Hi thanks to all my buddies here I successfully installed the samsung ssd evo hd into my MacBook mid 2009!

- Yes, you should. It's a maintenance feature in OS X that will keep the drive in good condition. There are no disadvantages to doing it.
The instructions were given previously in the thread, but I'll repeat them here:
Assuming you are running OS X 10.11 El Capitan, open the application Terminal, paste in the following and hit Enter:
Code:
sudo trimforce enable
I dunno where you read that, but it is not true. Samsung SSDs work just fine with TRIM.
You may have read about an earlier Samsung EVO firmware issue that was causing slowdowns, but that was patched in a firmware update.
- Definitely not true. I've not heard of a single case of issues with it, and my own nearly 4 years of experience with Samsung SSDs with TRIM also doesn't give me any grounds for concern.
- It's not any simpler without it, and the age of the machine, once again, is no concern. Unless you consider it complicated to do the actual 5 second enabling of it. It requires absolutely zero user involvement past those 5 seconds until eternity.Thanks but it's an old 2009 MacBook I'll keep it simple so for now I'll pass on trim!
The only thing you achieve by not enabling it is making your SSD gradually degrade over time in especially performance and potentially stability.
Hi so I successfully enabled trim without any problems. Hopefully the 2009 MacBook will last longer
I have a late 2009 macbook with an ssd (adata, cheapy)
Trim on some samsung SSDs in mac will cause problems it is only one or two models (cant find link right now)
there are a bunch of SSDs which are trim blacklist in mac and should not have trim enabled.
Like I said it is very few.
I have trim enable personally.
240GB SSD and 6GB ram makes my 2009 macbook quite fast and usable for daily work tasks.
Edit:
found it.

- That's not a link. It's a nonsensical screenshot that says nothing at all about Macs or OS X.
- According to you. Please provide documentation if you want to contradict established knowledge.

You are mistaken. This queued TRIM issue was a bug in the Linux kernel and never impacted OS X.
we did this recently on a "late" 2009 MB; added all 4Gb RMA and a 480GB SSD. Allowed us to install El Capitan and works like a charm now.
my source was howtogeek.com
Will post direct link when home as it in favorites of my windows pc, im at work with my mac.
I have no experience with the said drives I only mention as may be useful to someone else thinking of upgrading.

I went and found the article.

Thanks for this information. I put in a SSD years ago and didn't even know about this being an issue until I read yours and others posts here. I'll be enabling TRIM tonight.
That is the same issue in the article I linked and it has nothing to do with OS X. This was a Linux kernel bug related to queued TRIM commands.
From this quote in your article, it appears the author is speculating the Linux bug (and blacklist) would apply to OS X, but it does not and the author is mistaken.
