OpenCore & OCLP Explained (OpenCore Legacy Patcher)

Thanks!

Your videos are awesome.

Good video! I OpedCore'd my 2012 MacPro for years, until MacOS Big Sur ... had to move on to some newer hardware then. Understanding OC is also super-important for Hackintosh builders

Perhaps Apple should introduce paid support for old Macs, I wouldn't mind paying a small fee for official support after a number of years, I'm glad we have OpenCore to fallback on.

I have a problem.. I have a PC hp 600g1 Hackintosh Ventura 13.5 is installed and installed opencore lagacy patcher0.6.8 But after patcher the graphics card hd4600, it happens that some applications do not work, either they open and close, or they do not open What is the problem and how to solve it Why does Opencore Legacy stop running s

Thank you so much for this video! Now I have a much better understanding of this whole, rather confusing, topic. I always thought that Open Core was some dubious borderline illegal software, but am now much more at ease with it.

This is fantastic! Thank you for taking the time to make this video!!

Great video

hello, pls help, i have installed and everything works, BUT I dont have hardware acceleration..video rendering is very slow..is there a way to fix that?? PLS HELP!! I7 8700 WITH GT 640 + OCLP latest 067...osx monterey

How quick are they to releasing a version of legacy patcher for new OS updates like Sonoma? My 2017 iMac was sadly chopped off and I don’t want Ventura to be the last version it runs. Does it usually take them weeks or months after the official major release?

Very helpful! THank you. I don't know if you can help me with this, but before installing Open Core Legacy Patcher and OS Ventura a few days ago, my imac was running OS High Sierra (hadn't been able to get above that update) and on an alternate boot, Linux had been installed. I think I f....d up and now I can only find a boot for Ventura which says EPI in it. Can I pull Linux and the old mac restore booters back out of the OCLPboot directly into Ventura, or has all the old stuff been overwritten by OCLPboot and OS Ventura? I am not much of a techie, but try. Thanks if you can refer me to any help to weed my other booters out of the OCLPboot directly into OS Ventura! AJ

Thanks a perfect summary and explanation

Hey, thanks for this amazing job! I was just wondering if it's possible to dualboot macOS Ventura along with either Win10 or Win11 on my 2014 13-inch MacPro.

Will future OS updates work, or will I need to repatch? Security updates etc...

Can I trust 0CLP with personal data on my machine? I know I have to make the decision myself and measure the risk blah blah blah, but do any of you have personal private information on an 0CLP computer? I mean what benefit do the OCLP guys get for doing this free work? Sure it’s open source but is it the actual code or is it just a copy of all the code and it’s what they say is all the code when it could be missing parts? Could these guys just look at anybody’s computer and what’s in it? I would love to Upgrade my computer but I don’t see the point of doing it if I can’t even use it for personal use. Do you or any of you out there? Have your personal information on these machines and if so why do you trust it? I would really like to know because I would really like to feel good about running Ventura on my old MacBook Pro and use Universal Control with my iPad. Thx

This is good stuff. Thank you for your time. Macgeek is a niche that is difficult to cater to and the macgeek audience on this platform is a difficult crowd. Thanks for taking the time. I am very appreciative of it.

I hope to update this iMac (2012) after I get a new M3 iMac/Mac mini this summer.
Could be that this goes through this process.

I thought I had to have a Metal supported gpu to do all this and run the new os. But it’s running Big Sur 11.7.6 on my cMP 5,1 perfectly fine with the Radeon 5770

A clarification please. Is open core restricted to the EFI partition, that is, it's on a different partition than Mac OS itself?

Great video this really is remarkable software. My question is what is going to happen when apple stops making an OS for Intel hardware??

Thanks for making stuff clear :)

for the os update model linux is way better and it is opensource

Hey, very good video and very informative so far. But I have one quick question! I have a mid-2015 Macbook Pro that has an aftermarket SSD, which Apple prevented from installing any subsequent OS. If I download and install OpenCore Legacy Patcher, will it allow the updates to go through on this aftermarket drive? I can't seem to find any documentation on this on the OpenCore installation docs, so I figured I'd ask before trying. Thanks :)!

OCLP has helped make my VERY upgraded Mac Pro 3,1 and my 2013 Retina Macbook Pro run better with unsupported OS versions than with the latest supported versions

I have 2 2011 5,1 Mac Pros and want to upgrade them both. I am curious, can I install OCLP on an external SSD drive just to test it out and then clone it to the internal one if I have issues? Also, does keeping the old bluetooth cards allow for hand off between devices or does it require the card to be upgraded?

i love how you make your own beats for the background, that's kinda sick

Could you use opencore to use an egpu with an apple silicon mac? Thanks

Can’t get it to work get I go through install then Mac reboots the. Takes me back to boot option every time

Infinite loop after finish iinstall...

What about Applr Keychain, is it safe and secure to use it with OpenCore ?
Thank you

I had no problem running MacOS Monterey til the latest Update on Virtualbox with a AMD Ryzen CPU and without soecific bootloader like Charmeleon or Clover, but Ventura is a different beast. Install performs normal but on first Boot after install it crahes and goes in a Panic loop.
However. I applied OpenCore legacy Patcher on a running Monterey and upgraded it with Ventura but it still runs into Crash panic loop at boot. Maybe its bc i cannot reach the Fuction keys required to let OpenCore Bootpicker apear on start? Can i use Legacypatcher or a trick to let Legacypatcher as the default boot option instead having to press keys combination during boot to make boot picker show up?

Greetings !
I have a question I recently installed Ventura 13.3.1 on a 2010 macbook with open core . Question , Can I use migration assistant to move data from a 2015 macbook pro running montery to the 2010 now ? I tried it and it gave me some trouble ....
Thanks ......

Great video

I just upgraded to the latest Monterey and I had to update the bootloader this time too . Really works great on my MacPro 5.1. Not yet ready for the latest OS though.

hi, i understand oclp 0.6.2 was just released. 0.6.1 and previous versions could not identify windows & Linux partitions at startup disk, because of which i had to go back to catalina-dosdude1....

OCLP efi bootloader fails to show partitions.. why?...Is this intentional

Can oclp 0.6.2 identify partitions... pls advise...thanks

I installed OCLP 6.1 on my 2012 Macpro a few days ago. I had a few issues but managed it after a couple of tries. I remember years ago hacking wifi firmware to get my wireless card to work on Linux. Compared to that, it was easy. It's so cool to be running Monterrey on old hardware! Thanks so much for these videos.

Thank you for the great overview!

Just found out about Open Core Legacy patcher today from a Mr. Macintosh video.

For sure I will update my trusty first ever MacBook Pro (Late 2013).

👍

Thanks Greg, you rocks !

Great explanation, I didn't really know how it worked, I just knew it worked. very insightful!

BRAVO! Very well explained!

Great video! Not too technical and easy to understand.

I work mostly with audio. I wish that something like Opencore existed for patching FireWire support into modern macos. I have 16 wonderful sounding preamps that will only work with Mojave or earlier. How would I go about developing an audio driver that would allow me to use my audio interfaces with big sur? Has anybody done this? Am I shit out of luck?

Why don’t you mention the Dortania guides?

Great Explanation!
I really haven't figured this out successfully, I kinda caved into buying a real Mac with the M1
Pretty sweet setup, still trying to figure out how to build a Hackintosh into my AMD TrueNAS Scale system im making to mess with.
Back in the early 2k's there was a ALOSHI DVD Image I belie it was called, I was able to get that version of OSX Leopard I believe it was, working on a PIII Dell tower & got it running ProTools.
but that was 20 years ago lol

Man I wish OC worked for me, and I wish I had the time to read and digest the full OC documentation so I could attempt the old school customized OC install. For me OCLP just never worked, and the so called community for me was next to non existent. The only support offered is a rather petulant and grumpy Baltic guy who simply doesn’t want to help anyone. I had to revert back to dodsude patching as that seems to work more reliably on my setup. I really wanted OCLP to work as it’s a brilliant bit f software and a really clever idea. Oh well

I've been far behind on what's been going on. Thanks for the update. And yes, the rapid deprecation of features is depreciating (not appreciated) :>

Thank you, for posterity, for doing this.
