bro. ur in a thread about getting it to run on unsupported macs. that is terrible advice
It is an open source project. So the other advice is to study and modify the code in branch macos-next, and help yourself. It is well written code but a substantial amount.
But sure any user modifications will be temporary, mainly to enable advance testing. The developers‘ work is the real thing.
 
MBP5,2 too updated to 26.0 b6. USB installer, external SSD.
Same modified OCLP 3.0.0n used for limited patching (non-metal graphics, USB1,1; but no wifi, audio).
Almost-smooth installation, failed once, resulting in the undesired extra - Data in volume naming, but no other negative effects.
MBP5,2 updated to 26.0b7 from b6 on external SSD, from USB installer. Again the modified* OCLP 3.0.0n used for limited patching. No surprises. Running fast enough to write this (with Firefox).

(*note modifications are temporary just to allow early Tahoe experimentation on my MBP5,2 and MBP11,1)


PS: this Tahoe SSD is now on the internal SATA, works well enough to "baptise" it this way.
For b8 I'll wait for the InstallAssistant.pkg, not sure if OTA would work. Need to boot the patched Tahoe with the bootloader containing the legacy USB map as foreseen in OCLP 300n (because of the USB1.1 patches, which make the internal keyboard/trackpad work) while without USB1.1 patches, the legacy USB map must not be present. OTA would transition from patched to unpatched while installing. With USB installer it's unpatched right away so clear which bootloader to use.

Exactly! If anyone wants Tahoe, he/she should modify and test himself/herself.
 
Tahoe-Patches are available for testing by developers only. For Suppose, if they even released it to public and anything goes wrong, people would blame devs! That's why there should be no preliminary support for Tahoe this year! Although previous macOS were available for testing but Tahoe's different!

We would probably see a release when issues are fixed and Apple makes macOS Tahoe official.

I know everyone is excited for macOS Tahoe. I am too excited! But we cannot harass devs by pressurizing them for beta support! I hope everyone agrees to my opinion! If not, feel free to prove me wrong.
 
I repeat, last year the situation was identical. I remember that some patches have made my machine unable to boot, I had to unpatch in recovery mode to rescue it. I didn't blame developers, no-one blamed developers, as we know that it is at our own risks.

T26B8/3.0.0n. OTA/OTW

Edit. A pleasant, unanticipated surprise, OCLP just asked to prepare while the B8 is downloading, (25A5349a). Could this be a long hoped for change.

I want any oclp dev to answer my question? If you like to answer it, otherwise ignore it.

September 9 is arriving in two weeks from now and macOS Tahoe will be officially released by Apple on September 12 or 16 because it cannot directly release on the same day I guess. Will oclp be able to release the patcher or atleast give us any ETA before releasing ?
 
You asking in the wrong place. This thread is a discussion between macrumors users about what they themselves are doing. If you want contact with the developers go to their Discord pages.
Okay actually I am shy to contact the devs there on discord. Do you think macOS Tahoe with OCLP with release when Apple releases official version?

I guess macOS Tahoe will be released by Apple in October. Because I cannot see release of any new M-Series Processor. If I am wrong, I would welcome anyone to set me right and tell me if it releases in September or October. If anyone don't agree with me, but if Apple releases macOS Tahoe on October 2 or 3, OCLP devs might have one more month to work on patches !
 
Because it might become for difficult for OpenCore Legacy Patcher v3.0.0 to release early. Maybe September could be the month of resuming commits on Github if Apple releases it one month after the release of iOS 26.
