My Problem

I had nearly maxed out my 750GB HD, and was getting tired of waiting for my computer to do mundane things like open Mail. But otherwise I was very happy with my old machine; the screen looked fine, and it ran Yosemite with no problems other than a little sluggishness.

My Fix

So I decided to upgrade to a larger, faster, HD, and double the RAM from 8 to 16GB. I opted for a 1TB hybrid mainly because the SSDs are still too pricey, and the hybrid came in a handy kit from iFixit.

I first copied my old HD using Carbon Copy Cloner. I tried SuperDuper first, but it stalled on read errors that CCC skipped over and warned me about afterwards. It also copied much faster than SuperDuper did, finishing the job in about 4 hours where SuperDuper was only about 3/4 of the way through after 7 hours.

I verified that I could boot from the copied drive, then my daughter and I took apart the case, swapped out the HD and memory, and put everything back together. At first startup all I got was a black screen and beeps from the computer. Oops--didn't slot the memory in well enough. Another quick disassemble, fix, and reassemble, and everything went great.

My Advice

This upgrade was definitely worth it--my machine feels effortlessly fast again. I don't know how much credit to give the hybrid drive versus the increase memory, but I'm definitely glad I upgraded.

Other advice:

- Copy your files to the new drive *before* you install it; you save a step, and can know right away if your new HD works properly (rather than waiting hours for the files to copy).

- Carbon Copy Cloner worked better for me than SuperDuper.

- If you want a clean install, download Yosemite and install it on the new drive before you swap drives, then use Migration Assistant to copy your files. I didn't do it this way, but it seemed like a good option.

- Careful with those screws! One stripped head can ruin your whole day. Might be a good idea to order some replacement screws, just in case.

My Problem

I had only 4GB of memory on my 21.5" EMC 2428 iMac (2 x 2GB Dimms). My son was having trouble editing films due to low memory. I bought 2 8GB Dimms and added them so now we have 20GB of memory and no trouble with the editing.

My Fix

Adding the memory was simple. It took minutes.

My Advice

One of the simplest ways to get more life out of your iMac.

My Problem

I speed up my mac by adding 6 GB of RAM (using a 8GB RAM chip) and changing the HDD to a SSD.

My Fix

It took 30 minutes and everything went perfectly!

My Advice

Do not mixed up the screws!

My Problem

needed more storage, and wanted more speed

My Fix

easy -- the guide videos at ifixit were all I needed and more!

My Advice

Increasing RAM from 8GB to 16GB on an early 2011 macbook pro (OSX Mavericks) had almost no effect for most applications I tested (3x repeat processing after fresh reboot, internet and all other applications closed). HOWEVER, the hybrid SSD which I installed subsequently had a pronounced effect -- boot-time halved, and general use in the OS even with many applications running is now faster than ever!

My Problem

Sometimes my Mac "hung". The software I used needed at least 4 Gb Memory, but preferred 8 Gb.

My Fix

I replaced the RAM Chips by 2 x 8Gb Ram Chips and the standard Hard Drive by the SSD Hybrid one.

My Advice

Everything was explained very clearly : I had no problems to fix it.

My Problem

The computer was incredibly slow and was running out of free space.

My Fix

The repair was quite simple and intuitive. According to the comments, I didn't disconnect all the wires and the repair was still really easy.

My Advice

You can add thin pieces of foam to reduce HD vibrations.

My Problem

My MacBook was getting too slow.

My Fix

It was such an easy task, finished it in less than a min after opening it up.

My Advice

Big improvement than what I was experiencing before.

My Problem

J'avais un problème avec la capacité de la mémoire vive de mon MacBook Pro. Je suis passé de 4G à 16G de mémoire vive. Il réagit très bien.

My Fix

Très bien

My Advice

Tout était très bien expliqué.

My Problem

Just a slow processing computer ever since yosemite. 4 mb ram is not enough and 500gb hard drive not enough space.

My Fix

Easy, I figured while had it open a new SSDHD was nessery along with 16gb ram. With the great instructions, I had both done in about 1/2 hour once i started.

My Advice

Read all of the instructions and prep properly. Propper preparation makes for an easy time of it. Hardest information to find was restoring the HD from time machine backup. Its easy just not complete coherent instructons anywhere.

To get the Mac to read the new HD so you can install the backup the HD has to be Format it first. You can not formant it in recovery mode. Once the drive is formated you can boot in recovery mode and Disk utility will find the drive once its plugged in.

My Problem

Just wanted to max-out the RAM

My Fix

No problems

My Advice

Keep up with the screws, make sure you reinstall the correct screws in the correct holes.
