macOS High Sierra (10.13) Unsupported Macs Thread

Hi all, just bumping up this request for pointers on how to get my MBP 5,5 to boot HS again. I tried changing the system date to Aug 1, 2019, but still unable to get past the bright boot screen despite running dosdude’s latest post-install patch. Also unable to re-install HS in-place, because “the installed version is more current”. Wondering if I can somehow rollback my HS version, or force an install in-place? Thank you in advance for your guidance!!
Maybe I am just slow but there is not enough info to work with in order to help you.
What is the recommended patch that you installed? Pull your HDD out to recover your data from a different Mac and do a clean install.
Thank you for your response. Unfortunately, I don’t remember exactly which patch it was now, but it was through Patch Updater, and in the December timeframe.
Thank you for the suggestion to recover the data and do a clean install.
Thinking out loud, is there any risk to upgrading to Mojave on MBP 5,5? And is it possible to roll back from Mojave to HS?
Yes, it is possible, but I usually do a clean install. I am not sure if you can go "in place" from Mojave to High Sierra and keep your datas.
I suggest you to learn about APFS local snapshots, they will allow you to return to "where you once were" in a matter of seconds in case of a failed update. It is absolutely must for our unsupported machines.
Apple released the security update 2020-001 10.13.6 with Safari 13.0.5. Can it be installed without problems? Does the patch 2.7.0 still work or we need for a new version?

Any word on this?
Also, can someone explain what the Security And OS Standalone Updates method in the first post accomplishes? Is that how I should be applying security updates to patched systems?
The instructions in the first message are incomplete, a passage is missing. You must follow those of 10.14.
I just did the update on my 3,1 Mac mini, and it went perfectly. I didn't even need to do post-install again. In my experiences on this machine, the updates work much better, and this time perfectly, if you use APFS.
Hi. Even I didn't really need your patcher (until now I used it only to download macOS installers), I would say that I'm grateful for your software. But now I've a question for which I can't find an answer here or in other place. Is there a way to prepare an external drive to boot with an iMac 8,1, doing all the job on my (2011) MacBook Pro? Can I install High Sierra with normal Apple installer and then apply your post-install patches? Or need I to create a pached USB installer in any case? I want to prepare a bootable disk for a inexperienced person that leaves far from me, so she can boot from external drive (I hope and guess she can do this), open team-viewer so I remotely import her user to external drive and after I verified all works flawless, I will clone the disk to internal drive.

This refers to a MacBook 5,1 (Unibody, late-2008) and applying Security Update 2020-001.
I tried to modify the update package "SecUpd2020-001HighSierra.pkg" as downloaded from Apple (using the apple.com / Support / Downloads section on their websites) and as described in Post #1 of this thread (post #1) as to section 'Security And OS Standalone Updates'.
Even added this addition, so that the volume check is not performed:
function VolumeCheck(prefix) {
to
function VolumeCheck(prefix) {return true;
but - that did not help, I always get a result (see picture), complaining that some readout for JavaScript resulted in an error :-(
![Screen shot Macbook5,1 SecUpd2020-001 HS.png]( "Screen shot Macbook5,1 SecUpd2020-001 HS.png")
Thus, in the end I booted with DosDudes patcher, applied the patches fresh (just to be safe; also did select "Force Cache Rebuild"), then restarted and went with the update as available from the AppStore.
That did go through the first restart round, the second restart never progressed (while it does on supported machines), I thus shutdown the MacBook5,1 forcefully after some time, and the next restart showed it is on version 10.13.6 (17G11023).
Hoping everything is fine now ...

Download the update.
Open the update.
Move the update.pkg to Desktop.
Open Terminal.
Enter "pkgutil --expand " now AFTER THE SPACE drag and drop the .pkg from the Desktop into the Terminal window and type after ANOTHER SPACE " ~/Desktop/Expanded" hit Return and wait, this takes a little while.
Quotes are not needed.
Open Expanded folder and then open Distribution file in Text Edit
Scroll down to the line
function InstallationCheck(prefix) {
enter the text return true; so it looks like this
function InstallationCheck(prefix) {return true;
Save changes
*******************
If you are trying to install the update to an HFS+ disk then there is another alteration you can make, before flattening and creating the package.
Again in the Distribution file scroll down to
function VolumeCheck(prefix) {
again enter return true; after the bracket, so it looks like this,
function VolumeCheck(prefix) {return true;
Save changes
Go back to Terminal enter "pkgutil --flatten ~/Desktop/Expanded ~/Desktop/Modified.pkg"
Using the .pkg extension is crucial.
Quotes are not needed.
One thing to note is if your Mac like mine has different OS's on it on other drives this method will tell you that all drives are able to install the update, DO NOT INSTALL ON ANY DISK/ PARTITION, ONLY INSTALL TO A DISK/ PARTITION THAT HAS 10.13.X ON IT. Select your disk wisely, and double check."
If I wanted to replace the original video card of my old MacPro 3.1 (ATI Radeon HD 2600) with a Metal compatible video card which card could I buy?. I don't have big graphics needs and I don't use games, I would like an inexpensive card to be installed quickly and that works immediately. Obviously it must be compatible with Mojave, now I use High Sierra.
GTX 780 3gb I have works beautifully, mine isn't flashed for Mac so no efi boot screen, but if you can find a flashed one you'd be golden!
For me, this upgrade caused a weird video card issue - after restart, it started behaving like it'd lost its driver (or as if it'd restart in Secure Mode). I'd be happy if there'd be an explanation and/or a possible solution for that. Finally, I could eliminate the problem by using the appropriate Quartz Debug app (however I don't really know what I was doing), still, I can feel that the problem is still present in the system.

Every security update has caused issues for me when I updated through the MAS, they would always fail with a recovery partition error, and the update would never show up under About This Mac > System Report > Installations.
I don't understand why but for some reason, after I updated my iMac 9,1 last night with both Security Update 2020-001 as well as Safari 13.0.5, both installed without issues from the MAS and both show up as installed in both the System Report and in the MAS itself.
Wonder what's changed now.
6 Gig GTX 980 Ti FTW also running very well, mine is flashed as i also run boot Camp (cough) windows
for gaming
Apple has released the Security Update 2020-002 for 10.13.6. Can it be installed without issues? Does Patcher 2.7.0 work or do we need an updated version?
The Best way to get a clean trouble free install of DosDudes Patched OSX 10.13 and 10.14 on an unsupported Mac
is to format the drive as APFS - GUID from the start with Disk Util before you install OSX
That way you get a clean install, and no up date issues,
Not to mention that APFS format runs noticeably faster and is more secure
than a standard Mac OS Extended (Journaled) installation.
just remember to Back up your personal Data before you do the formatting.
All the GTX cards from GTX 660 to latest will run fine,
Just remember to use the GTX 680 OSX 10.13 drivers for High Sierra,
It is a good idea to used a flashed card though so you can have a boot screen.
If you are running Boot camp Windows, I would suggest installing ReFind on your OSX drive
so you don't have to hold the Option key at startup,
I would also recommend installing ReFind If you are NOT running Boot camp Windows,
as it makes it far easier to access you recovery drive and any bootable media at startup,
such as OS installer CD's-DVD's-Thumb Drives and external USB drives when you want to boot from them.
I used this method when I installed DosDudes Patched High Sierra on My Mac Pro 3,1 and MacBook Pro 4,1
and I have had no hassles at all with either machine.

Unlike Security Update 2020-001 and Safari 13.0.5, which installed on my iMac 9,1 without issues through the MAS, Security Update 2020-002 and Safari 13.1 downloaded and installed through the MAS with the following error at the end of the install process:
The operation couldn't be completed.
(PKInstallErrorDomain error 112.)
After the restart, I got the Updates Not Installed notification. No updates available to install in the MAS.
FWIW, Safari now shows as version 13.1 and in About this Mac, the OS build number shows as 17G12034.
Hello guys is it worth ir to downgrade from mojave and install high sierra on imac 8.1 and mbpro 5.5 ?
Mojave and even Catalina works fine, but it seems like GPU is not working to its full potential in 10.14 and 10.15 would i get better performance in 10.13?
