If you ask me a question such as why my Mac keeps freezing, there might be several typical problems behind. Your Mac can freeze if the free space is very low, the memory is insufficient, macOS is old, a lot of programs get launched automatically at startup, or some incompatible applications are working in the background. Malware, broken system files, or hardware issues could also lead to performance. Installing software updates, deleting excessive files, and keeping track of resource usage through Activity Monitor are good habits. If why does my Mac keep freezing is something you experience continuously, you can start your computer in Safe Mode or do Apple Diagnostics for more advanced troubles.
