I have a 2011 15" MBP with 16GB RAM that is having issues... Whenever I run video video intensive applications (Video Surgeon and others) my computer locks up. I have to hold the power button down and reboot. I've taken it into the local mac authorized shop and it passes all tests. However I locked it up for them by running the app, and their response was the logic board is bad. The kicker however is they say the unit is obsolete and they can no longer get parts for it. This was confirmed by the local genius bar as well. I REALLY love this computer, and don't relish the idea of dropping almost 3k to replace it. So I guess I have a few questions: 1) Is this true, a 2011 is no longer supported? Seems odd but if so let me know. I'd be willing to spend $500 or so to keep this running, I just put in a 512GM SSD this summer! 2) I considered some refurbished units of similar age at a reasonable price ($600-900) but they only come with a 90 warranty. This does not seem wise. 3) If I HAD to, I could afford a new one, but not plan "A". Also, I've read about a lot of issues with keyboards, batteries etc. I do a lot of S/W development and use different VM's to run servers (Real resource hogs) and for the price of a new MBP, one can find laptops with 32-64GM RAM. I've seen lots of people rant that nobody needs more than 16GB RAM (I remember Bill Gates saying nobody will ever need more than 64k RAM...) But my guiding principal has always been when buying a new computer, get the mostest you can afford to help delay the inevitable obsolesce. So, my 7 year old MBP has the same RAM limits of the current model?! According to this and other sites, don't expect anything more than cosmetic changes for 2018 on the MBP, 32 GB someday. I realize #3 above kind hits the "Should I buy now or wait" button that everybody hates, not my intent, just tying to articulate my options as I see them. Thanks in advance.
