I have MBP late 2011 that was 4GB RAM. So I upgraded it to 16GB. It boots fine and I can use with Firefox and some other apps, but when I try to use it with some apps (Android Studio and XCode) those apps sometimes works and sometimes crashes.
The OS itself runs fine, except of instability on some apps after upgrade
I'm not sure why but I read this and it says maximum memory is 8GB. Anyone who can help shed light on this? I don't know what to ask better than this as I'm still confused with what is happening.
After running Apple Hardware Test I got an error. I believe something is wrong with one (or all) of memory modules. Here's a screenshot
