#TRIM ENABLER MACBOOK PRO SSD FAILURE MAC OS#

(A kext is a kernel extension, or a driver, in Mac OS X) In OS X 10.10 (Yosemite), Apple has introduced a new security requirementВ called kext signing. And as detailed in theseВ two posts., this issue was due to a new feature in OS X Yosemite. Please see the latest post on Trim in Yosemite:ДЄs some users may have noticed, if you try to enable Trim on OS X Yosemite, you can get stuck with a grey screen with a stop sign during boot. The extra drive caddy enables us to keep costs to a minimum by only needing the smallest SSD to boot from, while data can be shifted off to the spare drive.ДЄny problems or questions?

#TRIM ENABLER MACBOOK PRO SSD FAILURE UPGRADE#

That said, if youвЂ™re considering replacing your Macbook just because itвЂ™s slowed down, this SSD upgrade could really help. ThereвЂ™s also the formatting issue - donвЂ™t start deleting any data until you have a full external backup somewhere and donвЂ™t forget once itвЂ™s all working again to set up a proper triple backup solution (in fact, you could use your spare internal drive as a daily bootable backup just in case). The best rule of thumb before attempting to perform serious modifications on a laptop (or any gadget for that matter) is if you canвЂ™t afford to break it, donвЂ™t do it. Luckily no damage was done to the cable, but there were a lot of screws and a lot of work getting it open again. The problem - IвЂ™d forgotten to reconnect (or accidentally pulled out) the motherboard ribbon cable. This time around, I screwed it all back together and it failed to turn on. This is not my first time opening it up either - IвЂ™d already upgraded the main drive to the 500GB model years ago.

This procedure isnвЂ™t for the faint of heart. The next step is to format the new drive open up Disk Utility, select the drive, and format it with one partition and the usual journaled file system (the defaults). You can do this using the free TRIM Enabler utility. TRIM enables better performance by optimizing the file deletion process, and makes a significant difference.

Once booted, youвЂ™ll want to enable TRIM on the SSD, as Apple doesnвЂ™t enable it by default for non-Apple approved drives.

#TRIM ENABLER MACBOOK PRO SSD FAILURE INSTALL#

Turn on the Macbook and things should boot just fine as always - itвЂ™ll recognize and read your existing OS install thatвЂ™s not in the DVD drive caddy. Fix in the memory plate, clip the battery back in, and youвЂ™re done. Close the lid, replace the side screws, flip over, and replace the rear screws. Replace the motherboard ribbon and fix the keyboard back, slotting in at the front first. This will result in superb boot and application launch times, and who needs a DVD drive anyway in this day and age?Д¬lose the case up in the reverse order that you opened it. WeвЂ™ll then shift the current hard drive over to that, and place the SSD in the primary hard drive position. Today, weвЂ™ll be opening up the laptop, removing the DVD drive and replacing it with a hard drive caddy. Best of all you won't be sacrificing storage space, since we'll be putting your old drive where the DVD drive was. Programs will launch a lot faster, your boot time will be cut dramatically, and it'll feel like a new machine. Basically theyвЂ™re solid state memory, meaning no moving parts and significantly better performance. Is your old Apple laptop starting to struggle? Is the boot time so long that you can actually go out and buy a coffee? If so, perhaps it's time to think about upgrading your main system drive to a low cost SSD and getting rid of that useless old DVD drive.
