macOS 15 Sequoia on Unsupported Macs Thread

MacinMan said:
The limitation is, VMs can't use location services from the built in WiFi adapter, so I would need to get a USB one that I could connect directly to my Sonoma VM as a USB device, so it would be available in that environment directly.

I was under the impression macOS did not support USB WiFi adapters without disabling SIP and installing third-party kernel extensions… and only Intel. Would be interesting to see if you can do this in VM. Is it Parallels?

VMWare Fusion. I wasn't aware of the sip issues and WiFi, I thought, the device just needed drivers that were already installed, or offered a pkg installer.
 
updated to 15.7.3 and open core 2.4.1, But when installing root-patches it failed (15.7.3-24G419), when checking the Metallibsupportpkg library it misses a lot off files/folder. tried to download it manually, but the same missing files/folder.

Reinstall the root patches so that OCLP can download the 15.6.1 MetallibSupportPkg. 15.7.3 package was pulled because the patcher expected a file in the OS that no longer is there from 15.7 onwards and failed the patching.

i did that but i keeps downloading the 24G419 pkg and than failes. i fixed (i think) by renaming the 15.6.1 folder name in library to 15.7.3 so it can find all files/folders.

Oh yeah sorry, forgot to mention you indeed do have to rename the old if you do it manually.

Finally have a Sequoia build on my flashed 2009 cMP.

Overall things are working great except for Apple TV. Does anyone know if they made a change to require AVX / AVX2?

Since I did an update from an earlier unsupported version, I may have to do a clean install to resolve this, if this isn't a known problem.

Steps taken
  • updated open core to latest version
  • installed an upgrade of MacOS from Ventura
  • completed app updates as needed
  • Installed root patches
  • reverted all root patches
  • completed root patches again.
  • Tested following code in both True and False versions (though this may only work for Safari)
Code: 
launchctl setenv JSC_useJIT true; launchctl setenv __XPC_JSC_useJIT false

Anyway, Apple TV app closes immediately on app start, app store also will not load for me.

Fine if it is a known issue, I use this system for other applications that work fine.
 
Hi, I'm having problems with my mac pro 5,1 USB 1.1 PATCH

I used the OCLP patch, al installed flawlessly, but my keyboard and mouse are still not working without an USB HUB

What can I do?

Reboot with hub+keyboard+mouse attached. Reapply root patches.

Finalmente ho una Sequoia costruita sul mio cMP 2009 modificato.

Nel complesso funziona tutto alla grande, tranne che per Apple TV. Qualcuno sa se hanno apportato una modifica per richiedere AVX/AVX2?

Poiché ho eseguito un aggiornamento da una versione precedente non supportata, potrei dover effettuare un'installazione pulita per risolvere il problema, se non si tratta di un problema noto.

Misure adottate
  • aggiornato open core all'ultima versione
  • installato un aggiornamento di MacOS da Ventura
  • aggiornamenti dell'app completati secondo necessità
  • Patch di root installate
  • ripristinate tutte le patch di root
  • patch di root completate di nuovo.
  • Ho testato il seguente codice sia nella versione True che False (anche se potrebbe funzionare solo per Safari)
[CODICE]launchctl setenv JSC_useJIT true; launchctl setenv __XPC_JSC_useJIT false[/CODICE]

In ogni caso, l'app Apple TV si chiude immediatamente all'avvio e anche l'App Store non si carica.

Va bene se si tratta di un problema noto. Io uso questo sistema per altre applicazioni che funzionano bene.

Usa questo.

What does that Automator script do?
Click to expand...
Hi @PeterHolbrook

If you open this script with automator, you would see that it executes the following 2 terminal commands:

Code: 
launchctl setenv JSC_useJIT false
launchctl setenv __XPC_JSC_useJIT false

to disable the JavaScript Just-In-Time (JIT) compiler in macOS, but performance is drastically reduced.

This workaround addresses crashes in Safari, App Store, and Music apps

These settings are temporary and reset after reboot. To make them permanent, users must re-run the commands at each login.

Thanks for that.

I have an automator script to run the code I included in my post earlier. I will modify it to see if the 2nd false flag works for me.

Installed the updated MetallibSupport package 15.7.3-24G419 and root patched, on Sequoia 15.7.3: no noticeable change (probably based on the final Sequoia IPSW, which is still 15.6.1)…

… BTW, the latest Microsoft Teams now crashes, on MBP11,3 (previously, it worked normally…):

Edit: Downgrading to Microsoft Teams version 25290.302.4044.3989 fixed the crash; and this was possible also thanks to Homebrew, which currently has an older version: brew install —cask microsoft-teams. Let’s hope that a future updated version will fix the crash (which occurred also in a new, fresh test account: so it’s not user-related).

Edit: Updated to version 26004.403.4267.4118, and now the error is slightly different - a real mystery, also considering that it works on the similar MBP11,1 (luckily, I don’t need Teams)…

Updated on both a supported MM 8,1 2018 & an unsupported rMBP10,1 2012 running OCLP 2.4.1 from Sequoia 15.7.4 RC2 (24G508) to RC3 (24G512)

While downloading the update on the unsupported rMBP10,1 OCLP detected the download in progress and prompted to update the Metallib library:

No issues so far.

Hi,

I own an 2015 13" Macbook pro A1502. I updated to the latest Sequaio 15.7.3 using OCP. It works very however it suffers from one quirk:
Works very well on powering up, after using it for a while and even overnight(ie waking up from sleep mode) without powering down. I then shut it down. On powering up again the display is not right all the characters appear smaller and no wallpaper displayed. I solve this problem via reverting the patcher and then restart the unit and post patch again. Then it works well as normal. The process repeats everytime I power it down.
BTW I also own a 2015 15" i7 unit it does NOT experience this problem.
Anyone has any idea how to fix it?

Thanks in advanance appreciate all the assistance I got in the past.
