It's not just you – your Mac really does take longer to log in than it used to. That's because certain programs configure themselves to start with your Mac, and so when you log in they load in turn, adding seconds to your startup time.
Some programs are essential at startup – your anti-virus tool being a case in point – but many aren't always needed. What you need is some kind of means of controlling what these startup items do, and Startupizer aims to give you all the tools you need to do so.
Not only can it be used to disable programs completely, freeing up resources for those apps you don't need loading with your Mac, it can also be used to delay startup or allow programs to only start at certain times of the day – perfect if you only need a specific program during work hours, for example. You can even configure programs to start (or not to start) when a specific key is pressed during logon.
It's all very simple to use: switch the program on and a list of login items will appear. Choose how you want them to behave using the drop-down menu and then configure advanced options – like schedules and hotkeys – if necessary.
It's an app you're likely to use once or twice before it's set up to your satisfaction, and will appeal largely to those who frequently restart their Macs. The rest of us can probably just about get by without – particularly considering the price tag.
