The apps that are downloaded in the App Store can be automatically updated using the check update function in the App Store. What is the fastest way to do that for all non App Store programs? If there are many non App Store programs, wouldn't it be hard to make sure that all apps are updated if the only way is to open the programs one by one? Also, what are some programs (both App Store and non App Store) that should be installed to keep the computer safe from being monitored/hacked? Thanks.
