I have experience with both Linux and Mac OS environments. In a previous role, I was responsible for installing and troubleshooting various operating systems, including Linux and Mac OS. One instance that stands out is when I helped a client who was having issues with their Mac OS after a software update. The system was running slow and some applications were crashing. I started by checking the system logs to identify any errors, then I cleared the cache and repaired disk permissions, which resolved the issue. Similarly, for Linux, I've worked on setting up dual-boot systems and troubleshooting network connectivity issues. My approach is always to methodically diagnose the problem and apply the most effective solution.
