My wife has an old Macbook Pro 2010 15" 2.8 i7 that we have always just considered ded, especially since she primarily works on a 2017 iMac 27 and iPad, both of which we bought last year. Unfortunately, she needs something with a little more power than the iPad when she travels for business. I was just reading about upgrading the RAM in the iMac, which I am definitely going to do in the very near future, and got the idea to update her dinosaur MacBook Pro, which has basically been lying dormant for the better part of 2-3 years. My thought, based on some upgrade threads here, is to upgrade the HD to a 850 EVO 500 GB SSD and max out the RAM at 8 GB, even though it is only DDR3-1066 from OWC. I was also thinking about replacing the battery, but I am not sure if it needs it yet. All of these seem fairly straightforward to accomplish, at a 1/10th of the price of buying a new mac laptop, and should provide the ole bird with some new legs when called to limited action. But planning these upgrades got me to thinking about whether I need to check if this system is even worth upgrading, like testing if the CPU, logic board, graphics card, etc. is in good working order. I am a windows guy who is slowly being pulled over to the Apple dark side, so I am not sure on what to run or how to run these diagnostics to see if everything is in decent enough working order. Does anyone have any recommendations on what (1) needs to be done to see if the upgrade is worth it, (2) I should do to prep the system, or (3) any other recommendations for what to update/ upgrade? Many thanks!
