Easy ways to upgrade Macbook Pro's flash storage fr 256GB to 2TB

sunhux used Ask the Experts™
Anyone has a step by step instructions/guide on how to upgrade
a Macbook Pro 13" (2012 release)  flash storage of 250GB to 2TB?
Ideally all the apps (including MS Office, etc) & data are ported over.

Will need to install OSX to the new 2TB SSD or if possible, can I
use Acronis CDROM to just do a bare metal backup & restore
over?  I have Acronis though it's about 9 years ago version
which I've successfully tested (booting up from CD) to
restore for Windows laptops.

I'm a complete newbie in Macbooks & OSX.  

Pls recommend the compatible brands of SSD for the
Macbook Pro 13"  (Yr 2012) that could fit in.  Reckon it'll
void warranty but it's out of warranty any way.

Required sequence is to have a Mac shop do this for you.

Apple machines usually require hacking/shorting connections on cables when you try installing an OEM (non-Apple) drive into an Apple machine.

I've done this successfully on old iMacs. Never on a laptop.

What generally happens when you install an OEM drive without hacking the cable is you'll hear your fans ramp up to max, as the OEM drives don't have the Apple modifications which send temperature data to OS, so OS sees drives as running at high heat levels 100% of the time, then ramps up the fans.

Extremely annoying.

I'm a fan of the upgrades sold by Other World Computing (www.macsales.com) and have installed a number of them in personal laptops and desktops over the years. They have videos showing step by step procedures, buying guides that show you compatibility, and kits that include both the upgrade item and any necessary tools for opening the case and installing it. There is even a phone support line with a knowledgeable person in Chicago Land that you can call if you get stuck.

Their guide for upgrading the SSD on your 2012 13" MacBook Pro shows links for both the regular and Retina screen versions. Use the Apple menu "About This Mac" to identify your exact version (click the button for System Report... to get the Model Identifier (e.g. MacBookPro9,2 or MacBookPro10,2) to find out exactly which model you have.

My most recent experience was upgrading the hard drive on a 2011 iMac. I could have bought it from New Egg, e-bay or the like and saved a few bucks, but there would be no guarantee that the hardware would be compatible with my iMac. When I bought it from Other World Computing, the drive came with a temperature sensor and carrier, so the new SSD bolted in the same place as the old rotating disk hard drive and the fans stayed quiet.

I do not advise using Acronis to make your changeover. Instead, make sure you have a complete Time Machine backup of your Mac. Then download the operating system installer from Apple onto a USB flash drive; your Mac can support the latest operating system (Catalina OS X 10.15). Boot from the USB flash drive, install the operating system on your new SSD, then import apps and data from the Time Machine backup.
Here's some other ways.  There's no need to make a flash drive or use 3rd party software.  Get the SSD from Other World Computing (OWC).

Back up to a Time Machine disk first no matter what you do.

If you have an external enclosure for the new SSD, you can boot into recovery mode using command r and install your current version of OS X onto the external drive.  Once installed, go into command mode and "bless" the external disk so that it can be bootable.
Swap the SSDs and boot.
Restore from Time Machine, or use Migration Assistant to migrate the data from the old SSD.

If you don't have the external enclosure, you can also Swap in the 2TB SSD first.
Boot into Internet  Recovery Mode by holding option command r during boot.  
Select Disk Utility and format the new drive.  
Quit Disk Utility.  
Start Internet Recovery to install the Original OS that came with your system.  
Upgrade OS X to  the latest OS X. (Catalina as of this writing)
Restore from Time Machine backup.

Again, there's no need for any 3rd party software if you're familiar with the Mac OS.  You can technically boot into single user mode and used dd to clone the disk.  You can also boot into recovery mode and use disk utility to clone the disk.  There are multiple ways to duplicate data on your Mac.  You can even Recover the OS, then use rsync to copy the files.

I never had trouble with cables or Mac disk on old Mac Pros and Old iMacs.  I never bothered with flat/thin screen iMacs, because we went with Mac Pros instead.  I have upgrade Macbooks Pros and Airs with no issues when ordering from OWC.
If you're in the USA, the Magnussan Moss Act allows you to make repairs and changes to your system without voiding your warranty.  The manufacturer must prove that you materially damaged your system before they can refuse warranty.  Switching a SSD does not void your warranty.  Your system lost its warranty coverage due to age, so it's a moot point.

You should find out the law your jurisdiction.  There may be something similar.  Don't brainwash yourself with the false idea that opening your system will void your warranty.  A lot of companies have been slowly pushing that idea, but it's wrong, especially in the USA.  It's their way of slowly taking away the right to repair.  They brainwash the masses into accepting their agenda and forgetting the laws that protect them.  Then they quietly attempt to pass new laws to water down the original hard won rights.  It's easier after people are brainwashed so they don't object.

MacBook Pro 13" with Retina Display? Yes

It's actually 2013's model as my colleague told me  2012's model can be opened (he has opened his
& added a 2nd SSD for Windows while original SSD still on OSX) while my kid's model is soldered &
he advised that it's best an authorized Apple shop opens it


> opened his  & added a 2nd SSD for Windows while original SSD still on OSX
ie his Macbook Pro  2012  supports 2 SSDs in it.

Can my model support 2 SSDs?

The compatible SSD are listed in the above link. The SSD is not soldered but you need to be skilful in opening up your MacBook Pro.

You can have one SSD only for your MacBook Pro.
Only the RAM is soldered.
