Hi. I just clean installed 10.7.3. Everything looks fine. I also have a thumb drive if something wrong happens. I created the boot drive and we I installed, 10.7.4 was available in MAS, so it was like "d'oh!". I see that 10.7.4 is out. As I haven't started yet to install the apps, it has any sense to clean install again with 10.7.4 to start with it? I ask about the improvements in security due to "flashgate". What do you think?
