I'm new on this forum, I appologize if I make a mistake :)...
I tried to install Niresh Catalina on my laptop, but I can't finish the installation properly.
I have a "Memory panic stackshot succeeded" error.
I seems to be an error due to "ACPI", with error "AE_ALREADY_EXISTS".
This is a link of a video of my screen in slow motion https://photos.app.goo.gl/BHkou4WEg33DA9ib7 (I can do another if logs are not visible enough)
This error appears after the 10-15min loading of the installation, after a reboot.
This is my laptop https://www.ldlc.com/fiche/PB00167274.html.
If someone can help me, I will apreciate a lot!
The laptop in question: Acer TravelMate 8472 TM8472 (Model: ZQ3) (refer to the "Spoiler" at the end if you want the machine specs)
"So what are you bugging us for?" Good question, because I am usually an introvert and usually just keep looking for answers but I could not find some. Jumping to it...
What does not work and I would like thoughts on:
Bluetooth does not register, used to on previous installs (sorry, I did not pay attention to see if this was caused by me updating to 10.8.5 but that was necessary for the below functions) (It does not work in Debian either - Ignore) LAN and WLAN - I have found Kexts (somewhere, I think I just lost them... dang it...) for the WLAN but I have yet to try them, nothing for the LAN I know this is cheating but I read that The NDISulator for FreeBSD (HINT HINT) is a port of NDISwrapper for Linux that runs Windows XP network drivers in Linux or BSD Brightness controls work from the middle down on the "Sun" brightness overlay, I got this far from following this: https://www.insanelymac.com/forum/topic/287133-guide-backlight-brightness-for-intel-80860046-1st-gen-hd-gma-5700mhd/ but I am kind of thinking of trying: https://www.insanelymac.com/forum/topic/287133-guide-backlight-brightness-for-intel-80860046-1st-gen-hd-gma-5700mhd/?do=findComment&comment=2214344 . My "magic number" is: 0xF I used DSDTEditor in Windows, since I figured all the drivers are loaded, to extract the DSDT and compile something that somewhat works... Wake from sleep issue - I tried the above guide for that but I get a no backlit display and I can see that the cursor in the password field is not flashing when I use an external light source, but it will reboot when I press Ctrl + Alt + Power "button" (it is actually a slider) and then also clear my freaking CMOS right down to the clock... yeah I have the ACPI fix implmented and it usually works... DVD Player.app reports that no viable video device was found (personally I don't care about the DVD Player.app problem, just wanted to put that out there for the heck of it) The microphone port always sounds like it is going through a [dirty] guitar effects petal no matter what sliders are adjusted
Likely causes of:
Bluetooth (BCM92046), WIFI (BCM943225HM) - So, I USED TO be able to turn on the WIFI from within Windows then reboot into Mac OS and have it work but I noticed recently that the indicator light for them turns off BEFORE it reboots now. When Windows or Android load, it lights up- "No... really, captain obvious?!"... anyways... working "No really Sherlock!" so OBVIOUSLY, the OS has to activate them... and preferably ignore the wireless switching button For the WIFI module, if you omit the 9 and HM in a search, results appear! Brightness - Will get reset to full "Bright light! Bright light!" when a "Load System Defaults" is applied from within the BIOS settings but like the WIFI and Bluetooth the OS will forcefully take control of it Microphone In sounding dirty - me being lazy with the audio drivers LAN (BCM57760) - I dunno... when I search it, nothing comes up...
"How did you get this far?"
Update the BIOS, this is oh so very important (refer to the battery section of the "Spoiler" for the reson) PLEASE BACKUP YOUR BIOS FIRST! PLUG THE MACHINE INTO THE AC ADAPTER/CHARGER! DO NOT FORCE THE COMPUTER TO SHUTDOWN NOR REMOVE THE BATTERY NOR UNPLUG IT FROM THE AC ADAPTER/CHARGER WHILE IT IS UPDATING! I WILL NOT BE HELD LIABLE FOR BRICKED MACHINES! So it will boot off of the (Niresh) Mac OS X 10.8 with no changes to anything "Awesome" but you may still need at least a USB mouse "Aww" If you have the option to remove the display drivers/kexts otherwise it will not to boot or not display If you forgot this, breathe "You think that's air your breathing?"... anyways... during the bootloader, go into single user mode [ -s ] and follow the on screen instructions to allow for modifying the files. You will want to PREFERABLY create a folder where Mac OS cannot read them and move the IntelHDGraphics Kexts into it You are likely going to need an external USB keyboard as well now that it is installed Now install the described Kexts in the "Spoiler" associated with the hardware to get more functionality and loose the USB HICs
Any help pertaining to the Bluetooth, WIFI, LAN, bizarre brightness and wake after sleep backlit display issue would be wonderful... Thank you for your time and I hope that I helped anyone else out with some of their own issues pertaining to the Acer TravelMate 8472 TM8472 ZQ3 no nVidia with i5 laptop...
