WeWu Level 1 Level 1

Hi all,

I have a mid-2012 MacBookPro Retina 15" running Lion 10.7.5 (11G63, which fixed the TimeMachine issue).


I teach at university and have to deal with 2-3 different beamers a day, maybe 8-9 different beamers and external monitors a week. Our school is equipped with HDMI and VGA  for most of the monitors and beamers.


I have issues with the MBPR crashing on waking up from sleep, or applications crashing (Dreamweaver and Keynote are favorites), and every now and then pictd decides to crash and I have to restart the system to fix that.


But I have an issue of the MBPR crashing when I remove the HDMI cable (sometimes when I insert it again). This is not just annoying - it's why I switched to Mac from a PC because I was sick and tired of blue screens. I only have 15 minutes between classes and do not want to have to reboot between classes, or have my system reboot in front of the eyes of the students (displaying the last letter I wrote, the last document I was writing, etc.).


It seems to be okay with VGA with a Thunderbolt adapter. But the HDMI (which is supposed to be a better resolution) actually always chooses 800x600 pixels (duh) for presenting, I have to manually choose a different resolution if I want more pixels.


Any ideas what the problem might be?

Thanks every so much!

MacBook Pro with Retina display, Mac OS X (10.7.5)

    try mdp to HDMI adapter as fast solution. Try other HDMI cable.

    When you have time try to find dependencies - when it crashes? Is it same beamer every time, or same software, or anything in common between cases?

    Try it at home with TV over HDMI.


    also posting here crush dumps can help a lot.

    The MBPR has a built-in HDMI - what is the mdp-2-HDMI adapter? I can't use other cables, as they are installed in the lecture hall. It is different beamers/monitors - and not consistent that it always crashes on the same beamer. This last one (which prompted me to write) didn't write a crash dump to the kernel (panic) log, the last entry there is from October. I will try and collect the next log - when I wake the system from sleep it seems to overwrite all of the logs.

    there should be some system in crashes, try to find it.

    Also it is strange that you have only 800x600 res. May be some settings in all beamers, done by admins - is it possible? Ask appropriate person.

    I have the exact same problem.


    I put my Macbook to sleep, take it somewhere, and insert an HDMI cable.

    Then, when I open the lid, it is doing a fresh boot... really annoying!


    I'm running Mountain Lion 10.8.2 on a 15" Retina Macbook Pro.

    Colleagues with just MBP on the same beamer don't have trouble, they get better resolution from the start, I have to change it by hand.

    I installed Xcode (all 4 GB of it...) and the frequency of crashes has decreased. I was about to state that this solved my problem when PowerPoint crashed in the middle of a lecture and I had to reboot the Retina, to the general amusement of the students watching me struggle with the machine. I still have trouble with occasional and non-replicable crashes of software (Dreamweaver, now iCal) just seconds after inserting the HDMI cable.

    I have the exact same problem too.


    My MBPR is crashing when I insert HDMI cable, system no response even I close the lid and monitor always on.


    I tried power on MBPR with connected HDMI cable, it just stop on gray apple.

    same problem here.


    15" MBPR completely freezes (no kernel panic or nuthin') when i connect HDMI.

    tried several hdmi cables, no luck.


    mini-display-port with vga: blinks once when i disconnect it, but detects nothing.


    also i have a dead pixel in the middle of the display, but i guess it's just time to get this fancy computer over to the israeli equivilent of the genius bar.


    any luck with anything, anybody?

    Here, new MBPr 2.7 with Panasonic Plasma thru HDMI without problem, 10.8.2 OSX.

    I had an OS update (Mac OS X 10.7.5 (11G63), Kernel version Darwin 11.4.2) and now it defaults to 800 x 600 pixels (at least without crashing), then adjusts itself to something marginally better. I can then set it by hand to the desired resolution. Not optimal, but at least noch crashing.

    Experiencing very same issue on 10.9.1 MBP Retina 15 2012
