Best Mac OS for Mid-2012 15" Macbook Pro

Sep 22, 2018 4:49PM PDT


My 6 year old Macbook Pro is still running the Mountain Lion it came with.
Below are specs:

Mid-2012 15" Macbook Pro
1680 x 1050 Display with NVIDIA GeForce GT 650M
8GB 1600MHz DDR3

It a lot slower now due to the apps and garbage I have installed over the years.
So I am planning to backup all data, and install fresh OS.

Which OS version would you recommend which will still keep it running well for atleast next 2 years.
I mean the best compatible one with the hardware, without slowing down the machine too much.
I have installers for all the below which I downloaded offline over these years:

- Mountain Lion
- Mavericks
- Yosemite
- El Capitan
- Sierra/High Sierra

Thank you.

Is to run the latest that is supported. seems to note you can go to High Sierra.

For our work (office/lab) we run the latest because that is where our clients are at so we follow the clients. We never worry about "MacOS x.y.x is the fastest." But some have that issue. They need to choose the version they need. As such this is just how we run our show, so your answer may differ.

I have a 2012 iMac 2011 which struggles

to provide adequate service when running High Sierra.
With Sierra it is fine.

While Apple say that both our machines can run the latest OS, I would take that with a pinch of salt.
Being able to run it and being able to enjoy running it are two different things.

Step up to El Capitan and that's all good, move up one.

Your Time Machine backup will allow you to restore to the previous OS should you find one that stretches you MBP too much.

Seems the 8GB RAM is a good start.

Too bad they still have a HDD. I've been installing all SSDs now for some time.
