Hi, I’m looking for a patient tech-savvy person to give my desktop a thorough clean. It’s a mid-2018 iMac, running a bit slow due to clutter, dust, and a few unused programs. I’d like you to physically clean the exterior, remove dust from vents, and perform a software tidy: uninstall unused apps, clear caches, organize files, and optimize startup programs. Please bring anti-static wipes and a small air blower if available. I’d prefer someone comfortable explaining simple steps I can repeat myself and happy to work around my schedule between 9am and 5pm. Access will be at my home in Dublin. If you can also back up important files before making changes, that would be ideal.
