Description

**Guide(s):** OpenCore Install Guide, perhaps others (that I'm not familiar with)

**Link to pages with issue:** Every [`config.plist`](https://dortania.github.io/OpenCore-Install-Guide/config.plist/) page (Penryn, Clarkdale, Sandy Bridge, ... not sure about AMD; however, the quirk was required to boot 10.7 in QEMU, virtualizing Penryn on Zen 2)

**Issue:** The "AllowRelocationBlock" quirk, under OpenCore's `config.plist`'s "Booter" dictionary, is required to boot any version of macOS below 10.8 (exclusively) due to said versions not having implemented support for kernel sliding (KASLR). Without it, memory allocation will fail, presumably when allocating memory for the relocation block.

**Sources:** [OpenCore documentation](https://github.com/acidanthera/OpenCorePkg/tree/master/Docs) ("Configuration", section 5.5.1) + [this issue](https://github.com/acidanthera/bugtracker/issues/1854#issuecomment-964543309) on acidanthera's bugtracker
