Hi All,

This question has probably been asked a million times, but how do I sort out a slow MacBook???
I have the following MacBook:

MacBook Pro (15-inch, Mid 2012)
2.3 GHz Intel Core i7
8 GB 1600 MHz DDR3

and I apparently have 100 Gb left of a 500 Gb memory

Anyway, it is running PAINFULLY slow. To give you some idea, I spend most of my time watching the spinning colour circle, and I have just emptied my waste basket and had to sit watching as it counted the deletions one by one :(

I have no idea what the problem is. My suspicions are either one of 3 things, or perhaps its a combination of them all, Firstly, my hard drive is pretty full. Secondly it's pretty old now and although I got the maximum RAM i could at the time, it's not quite up to the job now as I'm running Mojave 10.14.6, and I feel ike with every OS upgrade it gets slower and slower. Thirdly, i use my MacBook probably only a couple of times a month, so suspect its always wanting to do updates or running them automatically whenever I log on.

The strangest thing is, some days it just seems to work perfectly fine, which is actually more frustrating than if it was constantly slow.

I have been meaning for a long time, to back it up using time machine and perhaps do a full system restore, and then reboot from time machine. Alternatively and I feel like I'm favouring this idea, i'm considering just drag and dropping all my files to an external hard drive. Reformatting my MacBook, and then re-importing them. The reason I am favouring this idea is, I feel that IF whatever is causing my issue is the fact that somehow over the years my files have just been badly managed and got messy, then surely if I was to back up using time machine and then reboot from said backup, then surely it would be completely reinstated with all the same issues??

Annoyingly I USED to be quite computer savvy, but with using them so rarely since i began work as a tradesman roughly 20 years ago, I feel like technology has left me behind somewhat. So please bear with me if I ask any strange or silly questions :)

I have tried Googling "Slow MacBook" but all that seems to achieve is a plethora of dodgy sites/software claiming to be a "quick fix" which I learned years ago to be very wary of.

Really hope you guys can advise me on the best course of action, as the alternative is to buy a new MacBook, which I'm happy to do, just a little reluctant to spend the best part of 2k on something I use so little if its not entirely essential to do so.

Thanks in advance.

Dan
 
Replace the ageing drive with a SSD and reinstall.
Should feel like a new machine again :)
This. My mother in law has an Early 2011 MBP. I swapped the spinning drive out for an SSD and double the RAM. The parts were more expensive then than they are now. Definitely worth the investment.

Machine still runs like a champ.
 
The OP's MBP shipped with flash storage.

If you've been upgrading the MBP over the years it might be time for a clean install…and probably the way you plan to do it. There could be some sort of corruption or compatibility issues lingering in your user account that, as you suspect, might be re-introduced with a Time Machine restore of your user account.
 
Thanks guys. Really appreciate the feedback. Didn't realise it was potentially such an easy fix.

Gonna buy a crucial 1 tb or possibly even 2 tb SSD.

With regards to the RAM. I currently have 8GB but have read somewhere that Apple claim that this is the maximum you should go to but I was hoping to upgrade to 16GB. Thoughts?? Any foreseeable issues, or is this potentially Mac trying to put people off doing their own upgrades/voiding warranties etc.

Lastly, I feel like i've seen 2 different layouts for the RAM slots. One side by side, and one on top of the other. Is this relevant to the 15" or 13" respectively?

Thats all for now.

Thanks again :)

If this is your model - no upgrade on RAM for you, sorry.

Here's how to upgrade the SSD, however:
 
Hi Wegster,
No my Macbook doesn't have a retina display.

Does that mean i CAN upgrade the RAM? And if so, can I go as high as 32GB or is that not really necessary? Would 16GB be perfectly sufficient do you think?

Thanks.

You can go up to 16GB.
 
It's NOT "the RAM".
It's THE HARD DRIVE.
Replace it
with an SSD, as others have said above.
You will be EXTREMELY PLEASED with the performance once you do this.

YOU can do this yourself.
It's VERY easy to do with the right tools:
- Philips #00 driver
- TORX T-6 driver
(get these online or at a hardware store)

ALSO...
Get something like this when you order the drive:
(very cheap)

ALSO...
Download CarbonCopyCloner (FREE to use for 30 days):

Put the SSD in the USB3 enclosure FIRST.
Then, use disk utility to erase it:
- if you're using Mojave or Catalina, choose APFS with GUID partition format
- if you're using High Sierra or earlier, choose Mac OS extended with journaling enabled, GUID partition format

Then, use CCC to clone the contents of the internal drive to the SSD.

NOW...
Do a TEST BOOT:
Reboot and hold down the option key CONTINUOUSLY until the startup manager appears. Select the SSD and hit return.

Do you get "a good boot"?
If so, look around to be sure things "look right".

OK, if you've got this done, NOW it's time to power down and "do the drive swap".
Go to ifixit.com to see the procedure (again, it's EASY).
Just be careful where the 3 long screws go.
You don't really need to disconnect the battery.
The hardest part is removing and replacing the screws.

Once it's back together.
Reboot -- AGAIN use the "option key" trick I posted above.
Do you get a good boot?
Do you get logged in ok?
Fine, one more thing to do:

Go to the startup disk preference pane and set the new SSD to be the "new boot drive".
Close system preferences and you're done.

Put the old HDD into the enclosure.
It now becomes a bootable backup!

Hi Fishrrman

Sorry just thought it may be a joint issue.

I'll get on with changing the HDD then, Thanks for the really informative procedures and tips, they will come in really handy. Especially the USB3 enclosure. Wasn't even aware such a thing existed. Looks like I came to the right place.

However, upon doing a bit more research, I discovered the following information on an Apple support website:

Storage1

  • 2.3GHz
    500GB 5400-rpm hard drive
    Configurable options:
    • 750GB 5400-rpm hard drive
    • 750GB 7200-rpm hard drive
    • 1TB 5400-rpm hard drive
    • 128GB solid-state drive
    • 256GB solid-state drive
    • 512GB solid-state drive
  • 2.6GHz
    750GB 5400-rpm hard drive
    Configurable options:
    • 750GB 7200-rpm hard drive
    • 1TB 5400-rpm hard drive
    • 128GB solid-state drive
    • 256GB solid-state drive
    • 512GB solid-state drive


    • My Mac only has a 2.3 Ghz processor. Does this mean I can only get a 512 GB SSD? Or is this info outdated?
  • Thanks for all your help so far, but I just want to make sure I don't buy something, attempt to use it and it's not compatible and may not be able to return it. Better safe than sorry.
