![]() ![]() So i contact apple support to get a solution to this, they advise me i must upgrade my laptop. I've managed to download OS sierra (Which is literally just a direct link download dmg from apple, on an article "how to install mac os sierra" that is the EXACT same format as the high sierra article, yet the high sierra link goes to the app store. many of which are not compatible with cataline yet, meaning upgrading is not an option I am a VFX artist and on-set coordinator in the film industry, so i rely on many applications and plugins. so more research turns up there is a terminal command that will directly download a mac os installer via apple servers. now the catalina has been released this feature is not possible. It should be noted aftter some research, i found this workaround WORKED FINE before the release of os catalina. im running mac os 10.4.6 on this macbook, so it takes me to "software update" in system preferences, where it proceedes to give me this error So i do my normally google for the apple link to get os high sierra, it takes me to the MAS, great! i click "Get". So my next option is to wipe the drive, use my macbook pro to create a bootable installer of os high sierra and use that to fix my damn mac pro. eventually boots into normal recovery mode revealing mojave as option wipe the disk using disk utility and start a restoreĢnd snapshot fails unknown size (around the same)ĬMD+shift+opt+R. which it doesnt allow me because my amd gpu is not metal capable, and i cant use the nvidia only because i wont see the recovery screen. ok recovery mode should work?īoot up using CMD+R. My next step was to try and get high sierra back. I chose Macintosh SSD, it manages to boot but there is obvious visual glitches and running horribly (as its using the unsupported GPU) i realize my mistake after checking the nvidia drivers and checking for updates. it gave me 2 options: Mac os installer or Macintosh SSD i then added my 5870 back in, and rebooted holding option to choose my disk. what i didnt know was there were no web drivers compatible, after an hour i shut the computer down via power button. I begin the installation, it goes smooth for the first phase, when it restarts i knew i wouldnt see a boot screen for awhile as there was that second progress bar to go through. i upgrade the firmware (as mentioned earlier) and start it back up. So i start the installer with the 5870 removed, it allows me to go ahead with upgrading my firmware. I did this because the mojave installer thinks the 5870 is my only gpu when its in there. So i started with removing my Raedon 5870, which i run together with the 980ti powering different displays. I run mojave on my 2019 macbook pro, running final cut pro X for some of my indie projects i run a newer version on my laptop that is not compatible with os 10.13.6 (my Mac Pro OS at this time), so i wanted to upgrade for this reason. i should have left it here, but i got greedy. Now this problem was purely from my own lack of research.Īs apple advised in their guide on how to install mojave on a 5,1: i upgraded my firmware to 144.0.0.0.0 The mods that are relevant to this are as follows:ĮVGA G2 1000w gold+ PSU powering the gpu fully so ive got a modded mac pro 5,1 that i bought and owned directly from apple in 2012 (so im the only owner). Modded Mac pro 5,1 upgrade to mojave rabbit hole, can she be saved? Hi there. Thanks for any anticipated help, much appreciated. Ive tried the "Reballing" as well and trying physically hard wiring and soldering etc, but even being a fully trained technician I decided in the end to do as minimal hardware changes as possible. Question? is there a way around this? because once the files are deleted, I can run the app developed by DOSDUDE1 and have my macbook boot up on the Intel GPU processor in a lower resolution all done in the least complicated way:) The Macbook is an i7 and with a 1TB HDD runs El Capitan 10.11.4 etc etc which I can certainly still use. ![]() “AMD2400Controller.kext” can’t be modified or deleted because it’s required by OS X. I came across a solution where you can take out the HDD and put it in an earlier model, I've a working 2009 model and then I accessed the Amd*.kext files in the extension folder and tried to delete them:( but I get the following message I've tried various solutions and have tried to avoid all the command line commands sugested in single user mode etc. I have the proverbial problem with the GPU on a late 2011 macbook pro.
