My 2012 macbook pro would have still been working today had an unfortunate water damage incident not happen a couple years ago. It was theseuses macbook in a way. Trackpad had been replaced. Microphone replaced. Battery replace. RAM upgraded to 16gb. SSD upgrade. Disk drive swapped out and replaced with hard drive caddy making use of that extra SATAIII. It was no slouch. Sure it was only a dual core but 2.5ghz is plenty for a lot of things and most software doesn’t even make much use of multithreading anyhow. Not anything I’d try and run on that computer at least. It could handle creative suite and that was enough. Older games like TF2 worked great too like 80 or 100fps with a little config wonking. I can’t even get my replacement m3 pro running TF2 that well albeit over wine because valve doesn’t like arm.
