JijiTheFox Posted June 25, 2020 Share Posted June 25, 2020 Hi All, I'm trying to install Catalina via Clover, however, it hangs on ACPI errors. I've managed to reduce this from 6 to 4, but there's still some outstanding. I'm thinking this may require DSDT patching to get by, but on the below information, how to do I gauge what I need to locate, and change values to? I've been lucky with past machines, rarely required a DSDT edit. The EC patch for Catalina has been applied. Model - Lenovo A540 CPU - Intel® Core® i5-4258U (2.9 GHz) Chipset - Haswell Boot - UEFI Clover GPU - Intel Iris / HD Graphics 5100 Resolution - 1920 x 1080 Storage - 1TB hard drive RAM - 8GB Link to comment Share on other sites More sharing options...

JijiTheFox Posted June 26, 2020 Author Share Posted June 26, 2020 Hi MaLd0n, I've attached the untouched tables within the CLOVER folder, incase there's anything else that could be problematic. CLOVER.zip Link to comment Share on other sites More sharing options...
