Lets Try on Ryzen Laptop 🙏

[maly70]

if macOS 26 is not installing you might need to change smbios to a compatible one

Such a shame for me, I will have to wait to get home from work to get this going. Should have just booked a sick day 🤣

The installation stops right after the first boot.
I have a 2019 Mac Pro, and smbios is still supported by Apple.
Need an Opencore update?

I am not certain but the fact that the installation is not successful on Intel at the moment could be (see attached).

The Beta Release is for Silicon Macs. Maybe we with Intel have to wait for sloppy seconds.

I guess the kexts need to be updated try -lilubetaall and see if that works

I tried that and same issue still persists

[jalavoui]

lilu and probably a lot of kexts miss this extra line

 

 

not sure about MacKernelSDK compatibility with os version 26

 

also kexts with this init logic might fail

Tahoe's kernel version is 25.

[maly70]

it is installing now, I removed RestrictEvents kext , It use to give me an error regarding server error(could not contact server...) now after I added macOS 26 beta in system settings I worked good

[jalavoui]

clover seems tobe using 26 instead of 25

In that case by my estimation, it will be anything past 2 to 3 days before we can run it on a Hack.

I say this because there seems to be a development stagnation happening on Github as far as Updates are concerned. 

 

Then again maybe the Developers were waiting for the new macOS to drop and we will get a flurry of Updates to accommodate this new one.

Hope not wishful thinking on my part because at the moment my face is firmly pressed up against the glass looking in at Tahoe but can't smell or taste it.

Interesting. Everyone, including me, gets different errors.😂

I'm enjoying the new look on my iPhone.

Yea my install panicked half way through the first reboot.

Unfortunately I didn't take note of where it halted.

I too have it on my phone but for me that's not good enough.

I need it on my machine, I can live without it on the phone.

After making changes to Config.plist, I get a message that it is not compatible with MacPro 7.1  😂
