Why did my MacBook Pro Retina 2013 freeze?

Question

macOS

RMBP 2013, core i5, 4gb ram. Hangs tightly without reacting to anything. Launched: browser, translator, microsoft office excel, etc. on the little things. It recently hung for 4 minutes, rebooted forcibly.
What's the matter, how to treat? Free 30GB.

Answer 1

RAM. It is not enough)
Still remember what you set. It may be that some driver or some oblique program hangs the system

Answer 2

When you turn it on, hold down D and run various diagnostics

Answer 3

perhaps a memory leak, some process loads the nonpaged pool to the limit and the PC hangs, due to lack of RAM, it is worth monitoring the RAM consumption.

Answer 4

4 GB of RAM is very little, not to mention the fact that it is all the more small for a beech with a retina. I don’t know why Apple released it at all, and then in the next. The update removed this modification. Apparently, they really believed in OS X Mavericks, which in turn carefully handled the RAM (with Yosemite differently). In fact, 8 GB is close, 16 GB is best.

Answer 5

The same problem appeared, only PROshka is more powerful for me i7, 16GB. Did you find the cause and solution?
