I upgraded to 8 GB of ram today from 4 GB and my macbook is restarting randomly in about 10 minutes after booting

Here's the crash log

Hope someone can help

EDIT: Safe Boot Has resolved My problem, Thanks

  • If you boot in Safe mode dos it work than? – Ruskes Jun 18 '15 at 15:23
  • Let me try. Just a minute – Dreamjar Jun 18 '15 at 15:32
  • Also in that crash report you cut of the bottom part where it says RAM .... Could you run the Apple Hardware test? I can not fix your hardware but we can try to find out if a software is making the problem. – Ruskes Jun 18 '15 at 15:39
  • How can I do the hardware test? – Dreamjar Jun 18 '15 at 15:58

    "Safe Boot has fixed my problem" isn't really a description of what solved the problem! Did you find the problem by using safe boot, or are you still only able to work in safe boot mode? – Rampant Jun 18 '15 at 20:16

First step in Troubleshooting to do is to start in Safe mode. (Hold Shift during start up)

That will eliminate 99% of foreign applications causing the problem.

That will also show if it is a hardware problem. Sometimes it is enough to start in Safe mode to fix small problems.

If problem continues, run the Apple Hardware test, that might show problems with hardware. (hold "D" during start up).

For more clearer picture of your system, I recommend to run the EterSoft analytical tool. EtreCheck is a simple little app to display the important details of your system configuration.


The best way to resolve hardware RAM issues is to isolate this around one of the sticks of RAM. This is most likely a hardware issue, that will only show as a bunch of random software impacts, making it really hard to diagnose.

Remove all the RAM, and put in only one new 4GB stick in, then start the Mac. If it boots and runs, then you have a good stick. Try the other one.

If the Mac won't boot with either, then try mixing a 2GB with a 4GB stick, as you already know your 2x 2GB sticks work. (sometimes you need both DIMM slots filled).


Your Etrecheck report shows the RAM to be OK.

8 GB RAM Upgradeable

    BANK 0/DIMM0

        4 GB DDR3 1333 MHz ok

    BANK 1/DIMM0

        4 GB DDR3 1333 MHz ok

It also shows some obsoleted start up items that you can remove.

Startup Items:

HWNetMgr: Path: /Library/StartupItems/HWNetMgr

HWPortDetect: Path: /Library/StartupItems/HWPortDetect

StartOuc: Path: /Library/StartupItems/StartOuc

Startup items are obsolete in OS X Yosemite
  • After a long session of using my Macbook it again restarted without any warning and I did a hardware test, but there were no issues, now I am doing an extended hardware test. Is it possible that the problem must be hardware? – Dreamjar Jun 19 '15 at 10:36
