Just upgraded my mac.
2011 to 2012.
I can see why the word ‘upgrade’ might cause amusement.
The new 2012 has dual boot. With Catalina and Sonoma. The person I bought from was really knowledgable in computing and macs so I am confident.
My 2011 has been used to the max. I put 16gb in as well as a 1tb SSD and recently a brand new battery.
And want for a better word it started to slow down. I had everything on back up and erased everything. It was a good time to ‘upgrade’ as a lot of letters on keyboard not even legible.

So. Can I stick my 16gb ram from my 2011 into my nee 2012. Which only has 8gb ram. I was told I can. As it wil just have a few less MHz.
And same with battery. Was told I can put this brand new battery in my 2012. No pony moving SSD for now as this nee 2012 has a 1tb SSD.

Is running Sonoma on this max advisable? The dual boot thing cause slowness??

Thoughts welcome.

Should be able to. The worse that would happen is that it won't work correctly, and you'll have to swap out the RAM again.


The battery is the same. It's an A1382.

Actually the battery is different.
The wattage is different. And it’s much bigger. Didn’t fit at all.
The 16gb has gone in and registered ok.
Will need a new battery.

Wasn't your original machine a 2011 15" MacBook Pro?

Ah no. It was 13 inch.
The ram seems to be ok tho. The ram I took from my 2011 13” into the 2012 15”. It’s registered on ABOUT

Ok, the 13" does have a different battery than the 15". It's important to give all the information as required.

The only difference in the two is the speed of the RAM. In the 2011, it is 1333mhz and in the 2012 it is 1600mhz. I think you can even mix RAM of two speeds.

You can get aftermarket batteries on Amazon. Look for one with good reviews.
