Happy 5th Birthday OpenCore Legacy Patcher!

Today is OpenCore Legacy Patcher’s 5th birthday!

On Dec 1, 2020, at exactly 12:08 CST, the very first 0.0.1 developer preview of OCLP was released to the public.

I would like to take a moment to thank khronokernel, dhinakg & all the developers!

Take a moment to read Khronokernel's (Mykola) wonderful OCLP retrospective article. You can learn more about the history of OCLP in one his last blogposts before he was hired by Apple.

I also made a retrospective thread on Twitter if you would like to take a look
