Hi folks! MY CURRENT HARDWARE: iMac 14,3 (late 2013) 21.5-inch model; 2.9 GHz Intel Core i5, 8 GB RAM, 1 TB HDD, ext. SuperDrive USB 3 self-booting thumb drive with MacOS Mojave installer ready MY CURRENT MACOS: MacOS 10.12.6 Sierra (Time Machine backup) OTHER SIGNIFICANT SOFTWARE: Microsoft Office 365 (2016) Adobe Creative Cloud (InDesign CC, Photoshop, Acrobat Pro, Illustrator, etc.) Final Cut Studio 3 (includes Final Cut Pro 7) iWeb 2009 I followed the 9-to-5 Mac video instructions and now have a self-booting Mojave installer on a thumb drive. For years, I have had conflicts with old drivers and software cluttering my system and slowing it down. Malware scans and system cleaning has only been partially effective. It's been over decade since I last clean-installed the MacOS. I've put this off for too long. Now, it's time to clean-install Mojave. Out of options here. I takes over five minutes to boot up my system. Apps often launch slowly as well. I have plenty of loose ends and compatibility concerns, but I've decided to look at clean-installing and moving up to Mojave. Is there any special technique I have to use to clean-install off of my bootable thumb drive? I also have a Windows 10 installer disc here that I bought several months ago so I could run Windows-only software occasionally. Is there any special preparation I should be aware of for that? Thanks in advance.
