macOS 10.14 Mojave on Unsupported Macs Thread

[trifero]

Hi @jhowarth
In order to install SecUpd2020-002Mojave, you must expand the .pkg file and then modify the "distribution" file.
Like this:
Move "SecUpd2020-002Mojave.pkg" file to the desktop
Open Terminal and writes this:

cd ~/Desktop

Press enter

pkgutil --expand SecUpd2020-002Mojave.pkg NewFolder

Press enter

Wait a few minutes
Go to the "NewFolder" folder created on your desktop and open the "Distribution" file with a text editor

Add: return true;
at the end of this line: function InstallationCheck(prefix) {

Like this: function InstallationCheck(prefix) {return true;

Add: return true;
at the end of this line: function VolumeCheck(prefix) {

Like this: function VolumeCheck(prefix) {return true;

Save the file

If you have not closed the terminal, write or simply copy this:

pkgutil --flatten NewFolder SecUpd2020-002MojaveModified.pkg

Press enter and wait a few minutes for the package to re-create

But if you closed the terminal, re-open it and writes this:

cd ~/Desktop

Press enter

pkgutil --flatten NewFolder SecUpd2020-002MojaveModified.pkg

Press enter and wait a few minutes for the package to re-create

Once the operation is completed, launch the file "SecUpd2020-002MojaveModified.pkg" The message "This software is not supported on your system" should no longer appear and the update should install.

AFTER INSTALLATION YOU MUST RESTART ON THE USB KEY AND RE-APPLY THE POST-INSTALL PATCH WITH CACHE REBUILD OTHERWISE MOJAVE WILL NOT START

Be careful if you have several OS on more disks/partitions in your mac because these modifications make it possible to install this update on any OS disk/partition.
AT THE BEGINNING OF THE INSTALLATION BE CAREFUL TO CHOOSE THE DISK/PARTITION OF MOJAVE AND NO OTHER.

Odd. I installed it in a non supported Mojave Mac without any problem.

Did you install it from the downloaded installer or through the Software Update mechanism?

How exactly did you handle the security update installation? Did you attempt to capture the first reboot during the security update installation so that you could option boot into the patched installer to reapply the patches? Or did you allow the machine to attempt a failed reboot and then did a hard reset to get back into the patched installer to reapply the patches. This is where things are unclear to me.... do you have to allow the machine to apply update changes after a first reboot before we reapply the patches or do we have to wait for a final failed reboot and do a hard reset at that point. I worry that if I attempt to do an option reboot too soon, I may be skipping some updates applied by the security update.

For me the last 2 security updates when I downloaded the updates then clicked on restart install the updates I would get the black screen with the Apple logo and progress bar and then a bit into the install my Mac would reboot right back into Mojave. What worked for me was to boot into the Mojave patcher check csrutil-status in the terminal and then typed csrutil disable in the terminal, the did a Pram reset command-option P and R let it chime a few times then booted back into the Mojave Patcher re-applied the post install patches then booted into Mojave checked the updated then downloaded it -restart it went through and applied the post install patches and it worked

Doing a parameter reset would seem quite unwise if you are using a machine with multiple drives and patched macOS releases like Catalina. Also, are you saying that the Security Patch is re-enabling CSR on the target volume? I thought dosdude1 added a patch on Mojave that disabled CSR on each boot, no? My real concern is whether we are only partially patching out that checks made in the Security Patcher such that it might not really be completing properly.

 

[TimothyR734]

I am only running macOS Mojave on my iMac 9,1 and doing a pram reset is to make sure all I have is in nvram is "no-compat-check" and and csr-disable is making sure SIP is disabled

When I installed the modded stand-alone SU 2020-002 update, on the first reboot I booted into the USB patcher tool and ran the post install patch and forced the cache rebuild. I didn't wait for the 2nd reboot, and it went fine.

So when you ran the modded stand-alone SU 2020-002 update installer, did it install the security patches before it initiated the reboot or not? My experience has been that Apple tends to apply their installation changes after the installer reboots upon that next boot. So if you short circuit that aren't we preventing the changes from being installed?

Also, after the installation, are you seeing the 18G4032 version when you click on the 10.14.6 version number in the 'About This Mac'?

Hello. I've just updated my mac pro 3,1 to mojave with dosdude1 method. All went perfect. Now I started to work and Photoshop is slow and in some browsers I have strange behaviour/flickering. Is it possible that my GPU, NVIDIA GeForce 8800 GT 512 MB in combination with mojave is the cause? If so, is there a solution or do I have to upgrade my GPU?

It happens before the reboot. So once you start the update process with the stand-alone installer you get the typical install window and if memory serves me it then exits to a black screen with the installation progress bar, after that completes it reboots, and I remember it was then that I alt-booted into the USB patcher tool to run the patches and rebuild cache. On the second reboot it was a normal boot back in where it will show that the update has been installed - through the About this mac > system report > installations.

I have the same set up except 2 of the 8800GT cards. When it first came out I jumped on it, but I've long since moved back to Sierra, 10.12.6. It's great here, stable, AND I have run into many that have said the same. MōwJāvé is the transition, was suppose to be High Sierra, to the all 64 bit Catalina. Catalina ran great too. But some of my must have apps that are 64bit didn't work so well. So, although I had minimal problems, I trust that there may be things that would be needed to support those cards that might be gone or altered enough to cause issues. I didn't feel all that stable in it. I may try it again, almost have a couple of times.

Did you apply the Legacy Video card patch after installing Mojave.

 

[womkeX]

Did you apply the Legacy Video card patch after installing Mojave.

I did the patches that were checked, when I chose my 3,1. So I'm not sure. I can do the patches again.

 

[L Caputo]

If you boot back up to your Mojave Install USB, then select Post Install Patches from the small panel that pops up on the bottom left of the screen. Select your machine model, Mac Pro 3.1 and then look through the list of options selecting the ones you need, check the Legacy Video Card option and this should provide the acceleration needed so the graphics run
smooth. Then reboot with Force Cache Rebuild checked. Hope fully this will solve your problem.
How long have you had 8800 GT in your mac. When I bought my Mac Pro 3.1 12 years ago it had an 8800GT
which lasted for 7 years before boiling itself, and that was meant to be a good life for it. Most folk were only getting about 3 years out of it. Now running an Nvidia GeForce 680 which is a 'Metal' capable card.

Hi all,
Mojave 10.14.6 (18G5033) SecUpd2020.003 successfully installed on MBP5,3 (After Distibution file modification)

Restarted on USB drive and reapplied Postinstall with Force Cache rebuild after update.

Only replaced AppleGVA.framework (for videos fluidity), HIToolbox.framework (for dock menu shadows), SiriUI.framework and Siri.app (for waveform) and all seem to be working properly for now.

The Legacy Video Card option did it. Thanks for the tip. Did small test in Photoshop and looked ok. Tomorrow I will work again and test it all day. Thanks for the tip.

It's still the original GPU, so I guess I'm a lucky.

Does the Nvidia GeForce 680 card works plug and play?

I read a thread about the RX 580 in Mac Pro 3,1 - but it's bit tricky and above my knowledge.

SO I downloaded and installed the security update my 2011 mini told me was available this morning. I rebooted with the dosdude patcher, reinstalled all the patches selected for my 5.1 mini and everything appeared to be fine, machine rebooted and everything is back, or so I thought...

I have no internal sound. The machine doesn't even recognize it. I rebooted to the USB patcher, reinstalled the audio patch, rebooted again, nothing. This is all I see.

I normally use this only for music, and the internal for all other things like youtube and such.

Any ideas?

EXCELLENT !!

Did the security update today. Everything went OK apart from the fact that the software update badge is back (offering Catalina). I tried re-doing the fix given by @alphascorp - either I'm not doing it correctly or it doesn't work anymore. Well - it sort of works initially, but when I press Check For Updates in Sysprefs the badge re-appears. If @alphascorp is around: could you please confirm that it still works. And maybe for completeness, post the fix here again if it does (or better still, add it to the front page). Thanks.

That's strange. I've downloaded it from there this morning and now it's gone but I can see it on my phone. Anyway you can go deeper: https://support.apple.com/en_US/downloads/macos
