Substitute for gfxcardstatus8/1/2023 ![]() ![]() The driver should survive software updates. Just launch the "Uninstall Rastafabi's eGPU Enabler.app" from the applications folder. If you disable monitor out in the costumisation section while installing my package you won't have those issues.If you have a 5k iMac you MUST have an external display or FileVault enabled to see the login screen! Refer to the guide linked above.You would need to judge whether your okay with this yourself. The default scaled retina resolution (2560*1440) won't be applied to 5120*2880 anymore, but only to 3840*2160.He also put up a guide dedicated for 5k iMacs. Many thanks for all the testers! - Especially DANgerous25 for his persistent retestings (I know it sucks).You should not use my package and goalque's script simultaneously.This also solves the login screen issues of the 5k iMac.) You can disable monitor out support in costumisation section of "Installation Typ", if you do not need it.The package will purge any of it's previous versions, so you can just install it.Run it (right click - open, if macOS blocks it).Using multiple eGPUs should work but needs to be tested. To properly set up your eGPU enclosure search the forum. Quadro Cards - Kepler/Maxwell/Pascal architecture.GTX Titan (xx) - Kepler/Maxwell/Pascal architecture.GTX 7xx (Ti) - Kepler/Maxwell architecture.Thunderbolt Macs (Thunderbolt 1 and 2 works, 3 untested) Whom is it NOT for (yet)? - AMD eGPU users. Whom is it for? - Professionals and amateurs requiring compute power using NVIDIA eGPUs, as well as people who want to drive additional displays and gamers. That got me the white screen and high fan noise.For 10.13 High Sierra NVIDIA eGPUs support please visit this thread please. If your MBP doesn't get to white screen before shutting down while attempting to boot, hold down the option key and boot into recovery disk. Previously I had tried GFXbench to test it, and it went straight back to no vertical lines at boot. It got heated up a bit but no GPU issue so far. I even plugged it into a cinema display and played HD on youtube. I then I let it cool down completely, (in fact I put it outside on the balcony.) I left it for about half an hour then switched it off by holding down the power button. If you boot and get vertical stripes > apple logo > white grey screen, let it run hot as the fans kick in block the keyboard from venting airflow or wrap the mbp closed in a blanket. I followed these steps and got a workable fix: Saw all the online action, the lawsuits etc… Hopefully apple will do a recall as it was bought by me for graphic intense tasks like video editing. ![]() I had similar non bootable problem with a MBP 17 inch (early 2011). gfxCardStatus (integrated only mode) is better in this respect so I use both and now I can say that the machine is very stable and reliable after all. After about a week of gpu-switch testing, however, I have to conclude that this solution has its drawbacks too: it works fine after shutdown (including abnormal or forced one), sleep, hibernation, but it does not prevent mbp from switching to dgpu on running graphic demanding apps such as googlemaps in browser. This saved me from frequent overheat shutdowns under blanket just to load the os (after overheat shutdown the system forcibly uses igpu but this state changes back after couple of boots so it becomes necessary to overheat again). The application runs from terminal, reportedly uses the same code as gfxCardStatus but writes the setting into NVRAM(PRAM) so machine remains switched to internal GPU on next boot(s)/wake(s). Please note that only source code is there so Xcode is requred to compile the binary. It seems that I have found more reliable or permanent software solution allowing to permanently disable discrete GPU and use mbp (mine is Mbp 8.3 17i early 2011) with broken discrete GPU (failing to boot) than gfxCardStatus 1.8-2.2.1, namely. ![]()
