macOS 13 Ventura on Unsupported Macs Thread

[thadoggfather]

Out of curiosity why are you still on Sierra? I know a lot of people who never upgrade but I would like to know what people’s reasoning is. I can never run old OS’s due to continually degrading software support

it works fine. dont wanna fuss with boot camp either it works fine with win10 and all my home-brew stuff.
32-bit support.

No reason to upgrade really, for a period of time of several years it was my primary and only machine so the risk wasn't worth the possible benefits.

My primary is now M1 Air on Monterrey

as I said before the difference is the Generation of CPU 2016 Models use the i5-6360U / i7-6660U while the 2017 models use i5-7360U / i7-7660U. the difference is the support of 10Bit HEVC Enc/Dec-oding Capability of the 2017 machines and the 2016 doesn't support it and its a core feature of Ventura so the 2016 ones got dropped mostly because of HEVC

Could've still been supported without HEVC

Possible but 10 Bit HEVC is advertised as a CORE FEATURE meaning any System which don't support it won't run it Out of Box. That's the Same with Windows 11 Requirement for TPM2.0. Machine doesn't support it so the OS won't support the Machine Out of the Box

You can always tell when someone(s) don't bother reading the posts in the thread before theirs. 🤦🏻‍♂️🤣

 

[adam25255]

Please read the first post on page 1. Pre-haswell (2013 and older) macs are unable to boot the OS

I meant in future.(after patches are done) BTW someone had success with 2012 mini.

Spoiler: Spoiler: Current issues with Ventura on legacy Macs

Not officially supported in macOS Ventura, but currently not or only partly capable of running it

• Machines without AVX2 support will no longer boot
• This means devices with Ivy Bridge CPUs and older, basically all Macs older than Late 2013
• Would require an opcode emulator to work around it
• GPU drivers from before Kaby Lake (Intel) or Polaris (AMD) are removed
• Even if you can boot, you might not have GPU acceleration

Developers will investigate readding support. No guarantees

*More information will be posted as time goes by. Thank you for your patience as the developers and testers tirelessly work on getting new patches ready.

This is the command in terminal to see if mac CPU support AVX2

sysctl -a | grep machdep.cpu.features

You'll get a report out like this:


machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0 RDRAND F16C


So MacMini late 2012 Ivy Bridge and iMac late 2013 Core i5 out off race at the moment ...

Monterey is still going to get supported for a couple of years though

That’s not the point. It won’t get the newest versions of macOS. Security updates and patches are not even remotely the same thing.

Oh I know, I was just saying that it's not totally unsupported.

So am I good as it seems?

Just an OpenCore Legacy Patcher update needed if I understand correctly?

 

[Cognizant.]

well its not fully unsupported apple pushes security and Safari for Monterey for alt least 3-4 more years

Unsupported in this context means it doesn’t get new versions of macOS. That’s it. There’s no semantics.

sorry but i do not think that AVX1.0 is AVX2.0 🤔

So MacMini late 2012 and iMac late 2013 out off race at the moment ...

The late 2013 iMac, Haswell processor, supports AVX2

 

[FlorisVN]

both my 2014 and 2012 macmini's dont support AVX2 unfortionetly.
And other 2012 ,2011 and 2009 mac's I have also dont support it.

 

[netkas]

this thread aren't going to be as great as other unsupported thread.
all amd drivers of type x86_64h, h is for haswell, that basically mean avx2.0 is required, and those binaries are really using avx2:
just an example from x6000 gl driver bundle:
000000000001491e vbroadcastss %xmm5, %xmm5

only haswell based models has some chances, like mini2014, but intel graphics driver are KBL+ only
Ah well, they have only made trashcan usable with macos starting with 12.3.1 and now dropped it, previously had 8 years of reboots, rendering the machine mostly unusable.

The 2014 Mac Mini should support AVX2

 

[tchek]

The late 2013 iMac, Haswell processor, supports AVX2

Core i7 so ...

 

[Mystere65]

Core i7 so ...

Core i5 too

 

[tchek]

Core i5 too

There is no AVX2 on Core i5 only AVX1 on iMac late 2013 i5 even if they are Haswell both i5 and i7.

Summarizing from my Monterey's post (https://forums.macrumors.com/thread...unsupported-macs-thread.2299557/post-31155260):

1- MacBookPro11,2 installs and boots (on external USB SSD) Ventura just by using a supported board ID on config.plist. No Kext was used in the experiment.

2- The display is recognized as a 47in monitor without any acceleration (dropped support for Intel Iris Pro - Metal 1)

3- Touchpad only clicks and moves the cursor around (no scroll, etc.)

Can't wait to try out future versions of OCLP...

Thanks

I have the exact same config (MacBookPro11,2), I was able to install and boot Ventura by using 14,3 as the spoofed model in SMBIOS settings. Have the same issues as reported by you.

 

[TOM1211]

AVX 2.0 using the leaf7_features command on MacBook Pro mid 2014 i7 was hoping for 10 years out of MacBook Pro 2014 and at 8 years support plus security fixes it will have made it will be interesting to see if M1 gets that length of support good luck to those attempting.

[maclogon789]

There is no AVX2 on Core i5 only AVX1 on iMac late 2013 i5 even if they are Haswell both i5 and i7.

According to the Intel spec sheet for the 4570R on the late 2013 i5, AVX2 is supported

Intel® Core™ i5-4570R Processor

May I still be in business to run Ventura OSX13 under OCLP if it can be revised for OSX13?

My mid-2015 iMac 15.1 27" Retina has an Intel i5 4590 3.3 GHz Haswell processor that does support AVX2 according to the site below. (I am currently running OSX12.4 Monterey under OCLP 0.4.5 with no issues)

If only Apple would actually support MacOS versions for that long with things like Xcode.

Late 2015 27" iMac with Core i7.
No AVX2 support.

Looks like Apple is disabling it or not reporting it correctly in Monterey.

According to Intel, my CPU supports AVX2.
Instruction Set Extensions - Intel® SSE4.1, Intel® SSE4.2, Intel® AVX2

 

[Payne Mononymous Bachman]

What does AVX2 allow for if I may ask? Or why is it necessary.
