Chosen Solution
Hi everyone, today the following happened to my MacBook Pro 15” - 2011: After couple of hours of use it spontaneously rebooted showing the message: “your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up.” Around 20 min later, the same happened again. The MacBook Pro is running macOS HighSierra fully updated and no new software were installed recently. I tried both PRAM and SMC reset, but the problem persists. At this point, I formatted the drive and installed the whole system again. The situation is the same with the addition that now it reboots every time I try to shut down the mac. I tried to use the keys “ctrl+opt+cmd+eject” but it reboots immediately after pressing them showing the same problem message. All the component are original with the exception of the hard disk that was replaced with a SSD and the RAM that was completely replaced with new one. After installing the new components (ca. 3 years ago) i performed PRAM and SMC reset and never had an issue until today. Any idea on how to solve this issue? Thanks a lot!
I wouldn’t be surprised you would be starting having the first signs of a GPU failure. Download and try to run Valley, a graphic benchmarking app from Unigine: https://benchmark.unigine.com/valley If it’s a GPU issue your Mac will reboot or shutdown in a matter of minutes. If it’s not a GPU issue copy and paste or take a screenshot of the few lines of the report that should be showing after you get the kernel panic.
I agree with @arbaman probably a failing GPU. I have kept then running using gfxCardStatus fix software. This software allows you to just engage just the integrated GPU. gfxCardStatus places a small icon in the menu bar and displays a small n for nVidia or i for the currently active Intel graphics chip set. Just use your mouse to switch manually between the two when needed. If you disable the nVidia card permanently, you will should also notice an increase in your battery life. https://gfxcardstatus.en.softonic.com/ma… There is a new fix coming down the pipeline that I listened to on one of Rossman’s video with DosDude. It has to do with reprogramming the GPU itself. I have ordered the programmer in from China and will try to do a guide on this after I get it USB Downloader Jtag ISP Programmer ispDownload Cable Lattice FPGA CPLD HW-USBN-2 https://www.ebay.com/itm/USB-Downloader-… @danj thought this might be of interest to you ;-)
I downloaded and tried Valley as you suggested. The benchmark went all the way through. Once finished I changed the configuration from custom to extreme for the test, but the MacBook crashed before I could start it. Below the screenshots of the report showed after the crash. Thanks!
