I have been using this Opencore for about five months (my old mac is MacBook Air 2017) , and it was working very fast. Recently, it suddenly became very slow, and even simple browsing is now difficult. I think this may have happened because of an automatic system update.
Is there a way to restore the system to its normal speed? If not, is there a quick way to go back to the previous system version? I do not mind deleting all data; I just need the system to work properly again. ;(
