macOS High Sierra (10.13) Unsupported Macs Thread

[Philotech]

Hi, I got the same iMac 9,1 but with the standard Nvidia GeForce card. I can tell you that with the backlight control patch, there is no problem anymore with the brightness controls. After the patch they work fine.
Maybe anyone else can help you with your sata question?

I also have the same early 2009 iMac with the standard GForce graphics card (nVIDIA GeForce 9400 256 MB), and brightness control works like a charm, unlike under (not-High) Sierra.
HOWEVER, pretty much on every 3rd to 6th resume from sleep, the screen does not wake up again (i.e. the backlight does, but not the LCD, so all remains black), and I have to hard-restart the iMac which is very annoying because despite the SSD (replacing the original hard disk drive), restart until all applications are running again and CPU utilization is down to normal takes REALLY long (as in, 15 minutes).

I have searched all the web (almost literally) but found no solution to it. Any help?

Re-install the backlight control patch using the Patch Updater application.

Thank you!

[doublepost=1520587483][/doublepost]So we both have the exact same iMac 9.1. I also put in an SSD 850 Evo. And till this day the Mac works surprisingly good.
But, I am noticing that everything inside the box that is mechanical is slowly getting at it’s end, sometimes the ventilation is struggling.
On your question; maybe the Video card or motherboard is coming to its end of life. I’m waiting on the same sort of symptoms to send my machine on it’s well deserved pension.

Does anyone have a working two finger click trackpad solution for MacBookPro 4,1 trackpads? If I try to load the el capitan kext the computer reboots, not sure if I could modify the plists on the high sierra usbmultitouch kext or not. If anyone has figured this out let me know, as it seems weird all the other multitouch functions are working.

Well, I installed High Sierra yesterday, it all worked flawlessly, except for the Os not recognizing my extremely old Apple keyboard after the very first boot. I was also surprised to see it working snappier than El Capitan (even if it is probably due to my multiple in-place upgrades from Leopard to El Capitan over the years, I guess a new installation from scratch was probably needed). Thanks to everyone who made this fantastic tool possible!

Installed High Sierra on my iMac 7,1 that was upgraded with a T9600 CPU. Amazing that this old machine is running just fine, can even play 4K videos with VLC 3.01.

B.T.W is it safe to go ahead and install the macOS High Sierra 10.13.3 Supplemental Update. Wouldn't want to install it and then can't boot up or something else goes wonky.

Yes, it is safe! And highly recommended.

Sweet, thanks a lot man, went ahead and installed it with no issues.

Windows 10 has to be installed on a partition formatted with NTFS (can format during the install). I tried a few different methods to create a Win10 USB drive installer but could never get different Macs to recognize it, but they recognize the blank DVD when I burned the Win10 ISO to it. Bootcamp probably does something to the USB drive to get the Mac to recognize it but you can't use bootcamp to create a Win10 USB on High Sierra because it will say your Mac Pro isn't supported. Here's what I did for my MacBook and iMac that aren't officially approved by Apple to run Win10:

- Download the Win10 64bit iso (must be 64bit) from microsoft directly and burn to a dual layer DVD (it's slightly too large to fit on a regular blank DVD).

- Using disk utility make a partition on your hard drive for the Win10 install and format it as MS-DOS and master boot record. Name the partition anything.

- Put the Win10 install DVD in your drive and shut down. Start up and hold down option to get the boot options. Choose the picture of the disc that says Windows, not the one that says EFI. In a few minutes the Win10 installer will load.

- Choose to make a new install (not upgrade) and select the partition you formatted as MS-DOS. Click format then the "next" button on the bottom left will be clickable and the installer will do its thing. After 30 minutes or so you'll be at the Win10 welcome screen and will choose different configuration options then will boot to the desktop.

- Download the Bootcamp 4 and 5 drivers from apple. The Win10 install should have generic drivers for the Mac Pro ethernet but if not you'll need to find a way to get the bootcamp drivers on your Windows install (download on your Mac install and copy to a flash drive formatted in FAT32 for example).

- Copy the Bootcamp 4 and 5 driver folders to the C: drive on your Win10 install.

- In the search bar on the bottom of the task bar type "cmd" then right click the command prompt program that pops up and run as admin. Change the directory to the C: drive then to the apple folder in bootcamp 5 driver folder. After you're in that folder you'll type msiexec /i bootcamp.msi and the bootcamp 5 installer will load. after about 10 minutes bootcamp will be installed and you'll restart your computer. Make sure you option boot and select windows to get to the Win10 install.

- The drivers for your Mac pro should be installed now but you can check the device manager under "this pc". If you see any hardware with a ! next to it you can select it and choose to update the driver. Choose that you want to browser for the driver and to search sub folders for the location. Select the bootcamp 5 folder and if that doesn't have the driver search again but choose the bootcamp 4 folder.

That's about all there is to it. If you have any questions pm me.

Thanks Thanks Thanks

I've installed windows a few times previously. Never before like this. I guess you could say it happened this time intentionally by accident without bootcamp. Then, I've attempted to install bootcamp software a couple times. And, maybe has worked but? Also I guess the EFI is on the USB thumb drive? DK DK DK. I may need to boot via Bios anyway. That's my next hurdle.

BTW - Can't get boot options via option key without old GTO-429? installed [even then?] The purpose of installing windows is to flash "new" GTX 680 cos High Sierra won't on previous Ford Sapphire RX 460.

GTX 680 works perfectly well OOTB in Mac Pro 3,1 except no boot screen - so tempted to just live and let live thanks again.

[ softwareupdate ] Cannot install System Update 10.13.1 or any other app.

• App Store hangs when Update tab selected.
• softwareupdate command hangs at the terminal.
• I have run diskutilty First Aid and repair permissions
• I tried deleting com.apple.softwareupdated.plist and other suggested remedies for softwareupdate hangs.

...

I had something very like this doing an upgrade install on an early 2009 iMac. The cure was a clean install, restoring apps and such from a full backup (SuperDuper but CCC or Time Machine would presumably work) taken just before the clean install. The clean install also fixed a weird problem where attempting to scan from our Canon MF8280 would lock up the Canon until it was power cycled.

Any tips or troubleshooting suggestion are much appreciated.

( If softwareupdate can be fixed I am going to install a SSD and wifi card to make my 10 year old 2008 iMac "feature complete" again. ​

Thank you for great smart software that keeps my iMac 24" Early 2008 running!

It's sound like you enabled SIP. When SIP enabled, launchd can't inject my patch to softwareupdated. Without a running softwareupdated, softwareupdate and App Store are carshing.

 

[kschendel]

SIP was most definitely NOT enabled in my case, but it's worth checking.

Hello,
I'm trying to install High Sierra with a USB key made with the Patch of dosdude but i have a problem during the installation. I have the message " Request failed to initialize"

Someone has a idea or solution to fix the problem ?

Macbook Pro 5.1 (Unibody Late 08 with 8Go RAM and CRUCIAL SSD MX300 525GB)
Thanks

Yes, 1: reformat your USB stick and make the patch install-drive again. Or 2: use another USB stick. It's not uncommon, some drives won't do.

 

[CNiles38006]

It's not recommended that you convert the drive to APFS when using this patch, as it seems to cause some issues. If you choose to do it, however, you can do so in Disk Utility after booting from the patched USB installer drive... Just open Disk Utility, unmount the volume you want to convert, then in the Edit menu, select "Convert to APFS". Afterwards, apply the post-install patch with the APFS Patch selected.

I followed your instructions and converted my startup SSD to APFS with no issues, everything running smoothly. Your patch has really helped breathe new life into my "obsolete" iMac 7,1. Thanks for your efforts and keep up the excellent work.

I upgraded my Mac Pro 3,1 using DosDude1's macOS High Sierra Patcher today (on a new partition , fortunately, of my SanDisk Ultra II 960 GB Sata III 2.5 inch SSD).
However when I start up on my new High Sierra partition, it loads past the grey Apple and then goes to a blank grey screen and stops. Is this because of my AMD Radeon R9 270x 2048 MB graphics card? Any ideas please? Thanks.

 

[gto47]

Try formatting with HFS instead and see if it works. APFS drive support is spotty.

Another example of the nVidia 9400M glitch. Check out the 4th image of this (depressing) CNN article:

http://www.cnn.com/2017/11/14/africa/libya-migrant-auctions/index.html

View attachment 744277

Interestingly, this glitch in the CNN article doesn't happen in Firefox. The video in the CNN article I'm talking about is mid-article, and is the video that shows the map of the region.

However, Firefox does show the 9400M video glitch if you directly play the iPhone X video:

I wonder what the difference is.

DosDude1 came to the rescue for me: apparently nVidia is the way to go. I bought a GTX 680 graphics card and now High Sierra works on my Mac Pro 3,1

Anyone looking forward to the soon to be released 10.13.4 update.
Also will it be a simple App store update or will it require more of dosdude's magic?

Magic? It’s works without any magic if the App Store patches are installed. If WebKit based apps(safari, app store, itunes) not working after installation, only onix is required. This can be happen on any real, supported mac, so this thing is not only related to unsupported macs.

Yeah, I’m looking forward to it. Only for the iMessage syncing in the cloud, it’s finally going to happen.

I've heard this mentioned before but I'm baffled. Unless I've imagined it, I see the same messages on all my devices already. How is that happening if not through iCloud? Or is this something different?

Yes, there is a nice difference. You can do a little experiment: delete a Photo or little videofile in a iMessage threat of choice. On MacOS 10.13.3, you will see this media file will be deleted, but it will not be deleted in the same threat on your iOS device. (In beta MacOS and beta-iOS it does) This will also be the case for individual threats between Mac OS and iOS.
